Server Actions in Next.js are asynchronous functions that are executed on the server. They can be used in Server and Client Components to handle form submissions and data mutations in Next.js applications. Here are some best practices when coding Server Actions:

  1. Server Actions Configuration: Learn how to configure Server Actions in your Next.js application. You can configure Server Actions behavior in your next.config.js file. Learn More (https://nextjs.org/docs/app/api-reference/next-config-js/serverActions)

  2. Server Actions Behavior: Server actions can be invoked using the action attribute in a <form> element. They are not limited to <form> and can be invoked from event handlers, useEffect, third-party libraries, and other form elements like <button>. Server Actions integrate with the Next.js caching and revalidation architecture. When an action is invoked, Next.js can return both the updated UI and new data in a single server roundtrip. Learn More (https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions-and-mutations#behavior)

  3. Authentication and Authorization: Treat Server Actions as you would public-facing API endpoints, and ensure that the user is authorized to perform the action. For example:

'use server'
 
import { auth } from './lib'
 
export function addItem() {
  const { user } = auth()
  if (!user) {
    throw new Error('You must be signed in to perform this action')
  }
 
  // ...
}

Learn More (https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions-and-mutations#authentication-and-authorization)

#

  1. Closures and Encryption: Defining a Server Action inside a component creates a closure where the action has access to the outer function's scope. However, for this to happen, the captured variables are sent to the client and back to the server when the action is invoked. To prevent sensitive data from being exposed to the client, Next.js automatically encrypts the closed-over variables. Learn More (https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions-and-mutations#closures-and-encryption)

  2. Additional Resources: For more information on Server Actions, check out the following React docs:

Remember, Server Actions are functions. This means they can be reused anywhere in your application. They inherit the runtime and the Route Segment Config from the page or layout they are used on.

Yes, you can use Server Actions to fetch data and pass it to your client page. However, it's important to note that Server Actions are primarily designed for handling form submissions and data mutations. For data fetching, Next.js recommends using getServerSideProps, getStaticProps, or getInitialProps.

That being said, if you want to fetch data using Server Actions, you can do so. Here's an example from one of the knowledge sources:

'use server'

export async function fetchItems() {
  // Fetch data here
  return data_in_memory;
}

Then in your client component, you can call this Server Action to fetch the data:

'use client'

import { fetchItems } from './actions'

export default function ClientComponent() {
  useEffect(() => {
    const fetchData = async () => {
      const items = await fetchItems();
      // Do something with items
    }
    fetchData();
  }, []);

  // Render your component
}

This example uses the useEffect hook to call the fetchItems Server Action when the component mounts. The fetched data is then available for use in your client component.

Remember, this is not the recommended way to fetch data for your components. The recommended methods are getServerSideProps, getStaticProps, or getInitialProps as they are designed to fetch data at build time or on each request.

Handling large amounts of data like 11k news articles from an API requires careful consideration of performance and user experience. Here are some best practices:

  1. Pagination: Instead of fetching all 11k articles at once, fetch a smaller subset and provide a way for the user to load more articles. This can be done using pagination in your API requests.

  2. Infinite Scrolling: Another approach similar to pagination is infinite scrolling, where more articles are loaded and displayed as the user scrolls down the page.

  3. Server-side Rendering (SSR): With Next.js, you can use server-side rendering to fetch the data at request time, which can be beneficial for SEO and initial page load performance. You can use getServerSideProps for this.

  4. Static Generation (SG): If the data doesn't change often, you can use getStaticProps to fetch the data at build time and generate static pages. This can greatly improve performance as the pages are pre-rendered and served directly from a CDN.

  5. Incremental Static Regeneration (ISR): If you're using static generation but the data changes over time, you can use ISR to update the static pages in the background after a certain period.

  6. Caching: Implement caching strategies to avoid unnecessary network requests. This can be done at various levels, including the API, server, and browser.

  7. Optimize Data Lookup Performance: If you're dealing with a large number of redirects or routes, consider creating and storing a redirect map and optimizing data lookup performance. Learn More (https://nextjs.org/docs/app/building-your-application/routing/redirecting#managing-redirects-at-scale-advanced)

#
  1. Streaming: If the data is large or computationally intense, consider using the Web Streams API to stream chunks of the payload as they become available, improving your users' perception of how fast data is loading. Learn More (https://vercel.com/docs/functions/streaming#how-web-streams-work)

Remember, the best approach depends on the specific needs of your application and the nature of the data you're dealing with.

Yes, React cache is a function that allows you to memoize the return value of a function. This means you can call the same function multiple times while only executing it once. This is particularly useful for expensive computations or API calls.

Here's an example of how you might use it:

import { cache } from 'react'
import db from '@/lib/db'
 
export const getItem = cache(async (id: string) => {
  const item = await db.item.findUnique({ id })
  return item
})

In this example, getItem is a memoized function that fetches an item from a database. Because it's wrapped in cache, it will only fetch the item once, even if you call getItem multiple times with the same id.

However, it's important to note that the cache function from React is scoped to the current request. This means it won't work as a global cache. If you need to cache data across multiple requests, you might need to use a different strategy, such as the Next.js Data Cache or a third-party caching library.

Also, if your arguments are not primitives (ex. objects, functions, arrays), ensure you’re passing the same object reference. This is because the cache function needs to have only primitives as parameters.

Yes, using useCallback for your filter function can be a good idea, especially if you're passing the filter function as a prop to a child component. useCallback will return a memoized version of the callback function that only changes if one of the dependencies has changed.

This is useful when passing callbacks to optimized child components that rely on reference equality to prevent unnecessary renders (e.g., shouldComponentUpdate).

Here's an example of how you might use it:

const filterFunction = useCallback((value) => {
  // Perform filtering here
}, [dependency]);

In this example, filterFunction is a memoized function that will only recompute when dependency changes. This can help improve performance by avoiding unnecessary computations and re-renders.

However, keep in mind that useCallback has a cost, and it's not always necessary to use it. If your component is not rendering too often or the computation inside your callback is not expensive, then you might not need to use useCallback.

but i dont pass a function to the child. i am using the filter within the page

If you're using the filter function within the same component and not passing it down to a child component, you might not need to use useCallback.

The useCallback hook is primarily used to prevent unnecessary re-renders and computations when passing callback functions as props to child components. If a callback is defined within a component and passed as a prop to a child component, the child component will re-render every time the parent renders because a new instance of the callback is created on each render.

However, if you're using the filter function within the same component, the function will be recreated each time the component renders, but this won't cause any unnecessary re-renders or computations. In this case, using useCallback might be an unnecessary optimization.

Here's an example of how you might use a filter function within the same component:

const [list, setList] = useState(initialList);

const handleFilter = (filterCondition) => {
  const filteredList = list.filter(item => item.condition === filterCondition);
  setList(filteredList);
};

In this example, handleFilter is a function that filters the list state based on a filterCondition. This function is created each time the component renders, but since it's not passed as a prop to a child component, it won't cause any unnecessary re-renders.

Remember, premature optimization can lead to unnecessary complexity. It's often a good idea to start with the simplest solution and only optimize when necessary.

The useMemo hook is used in React to optimize performance by memoizing expensive computations. It returns a memoized value that only recomputes if one of its dependencies changes.

Here are some best cases for using useMemo:

  1. Expensive Computations: If your component includes a function with a computationally expensive operation, such as complex mathematical calculations or large array manipulations, useMemo can be used to ensure that this operation is only performed when necessary.

  2. Reference Equality: If you're passing an object, array, or function as a prop to a child component, and that child component is a React.memo or PureComponent, useMemo can be used to maintain reference equality and prevent unnecessary re-renders.

Here's an example of how you might use useMemo:

const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);

In this example, computeExpensiveValue(a, b) is only re-executed if a or b changes, otherwise, useMemo returns the memoized value.

However, keep in mind that useMemo is not a guarantee, and it's not a silver bullet for performance issues. It has a cost, and it should not be used indiscriminately. In many cases, React might still choose to disregard the memoized value and recompute it anyway for performance reasons.

If you're filtering a large array of objects, useMemo can be a good choice to optimize performance. It ensures that the filtering operation is only performed when necessary, i.e., when the array or the filter condition changes.

Here's an example:

const [list, setList] = useState(largeList); // largeList is your large array of objects
const [filterCondition, setFilterCondition] = useState(initialCondition);

const filteredList = useMemo(() => {
  return list.filter(item => item.condition === filterCondition);
}, [list, filterCondition]);

In this example, filteredList is a memoized value that is only recomputed if list or filterCondition changes. This can help improve performance by avoiding unnecessary computations.

Remember, useMemo is not a guarantee, and it should not be used indiscriminately. It has a cost, and it should only be used when necessary. If the filtering operation is not particularly expensive, or if the array or filter condition doesn't change often, you might not need to use useMemo.

Your useEffect hook seems to be doing a good job of filtering your data based on various conditions (dateFrom, dateTo, category, source). It's triggered whenever any of these dependencies change, which is the correct usage of useEffect for this scenario.

However, if the data set (data.pages) is large, this could potentially lead to performance issues as the filtering operation is performed on every render when the dependencies change.

To optimize this, you could consider using the useMemo hook to memoize the result of the filtering operation. This way, the filtering is only performed when data, dateFrom, dateTo, category, or source actually change:

const filteredData = useMemo(() => {
  if (data) {
    const allData = data.pages.flat(); // Flatten the pages to a single array
    let filtered = allData;

    if (dateFrom) {
      filtered = filtered.filter((item) => {
        const publishedDate = new Date(item.publishedAt);
        const fromDate = new Date(dateFrom);
        return publishedDate >= fromDate;
      });
    }
    if (dateTo) {
      filtered = filtered.filter((item) => {
        const publishedDate = new Date(item.publishedAt);
        const toDate = new Date(dateTo);
        return publishedDate <= toDate;
      });
    }
    if (category) {
      filtered = filtered.filter((item) => item.category === category);
    }
    if (source) {
      filtered = filtered.filter(
        (item) =>
          item.source &&
          item.source.name &&
          item.source.name.toLowerCase().includes(source.toLowerCase()),
      );
    }

    return filtered;
  }
}, [data, dateFrom, dateTo, category, source]);

This way, you're not performing the filtering operation on every render, but only when it's actually necessary.

#

Remember, useMemo is not a guarantee, and it should not be used indiscriminately. It has a cost, and it should only be used when necessary. If the filtering operation is not particularly expensive, or if the array or filter condition doesn't change often, you might not need to use useMemo.

You can use the filter method in JavaScript to filter out the objects in arr1 where the author is not in filtersAuthors. Here's how you can do it:

const arr1 = [
  {
    id: 1,
    name: "Name 1",
    author: "1",
  },
  {
    id: 2,
    name: "Name 2",
    author: "2",
  },
  {
    id: 3,
    name: "Name 3",
    author: "3",
  }
]

const filtersAuthors = ["3", "2"];

const result = arr1.filter(item => !filtersAuthors.includes(item.author));

console.log(result);

In this example, filter creates a new array with all elements that pass the test implemented by the provided function. The includes method determines whether an array includes a certain value among its entries, returning true or false as appropriate. The ! operator negates the result, so we're filtering for items where the author is not included in filtersAuthors.

Yes, useMemo does use a form of caching. It memoizes the result of a function and only recomputes the result when one of its dependencies changes. This can be considered a form of caching because it stores a value and reuses it until certain conditions (the dependencies) change.

Here's an example of how useMemo is used:

const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);

In this example, computeExpensiveValue(a, b) is only re-executed if a or b changes. Otherwise, useMemo returns the memoized (cached) value.

However, it's important to note that useMemo is not a guarantee. React may choose to "forget" the memoized value and recalculate it on next render, for example, to free memory for other operations. Therefore, useMemo should only be used for optimization, not for semantic guarantees.

Yes, you can use Drizzle with Vercel Postgres in a Next.js application. Here are the steps:

  1. Follow the instructions in the Postgres quickstart (https://vercel.com/docs/storage/vercel-postgres/quickstart).

  2. Install the drizzle-orm package to write queries, and the drizzle-kit package to define your schema and manage migrations:

pnpm i drizzle-orm
pnpm i -D drizzle-kit
  1. Create a schema.ts file for your database tables:
import { drizzle } from 'drizzle-orm/vercel-postgres';
import { sql } from '@vercel/postgres';
import {
  pgTable,
  serial,
  text,
  timestamp,
  uniqueIndex,
} from 'drizzle-orm/pg-core';
 
export const UsersTable = pgTable(
  'users',
  {
    id: serial('id').primaryKey(),
    name: text('name').notNull(),
    email: text('email').notNull(),
    image: text('image').notNull(),
    createdAt: timestamp('createdAt').defaultNow().notNull(),
  },
  (users) => {
    return {
      uniqueIdx: uniqueIndex('unique_idx').on(users.email),
    };
  },
);
  1. Install the @next/env package to load the environment variables outside of the Next.js runtime:
pnpm i @next/env
  1. Create a drizzle.config.js file in the root of your project, import the environment variables config, add the path to your schema file, and your Vercel POSTGRES_URL connection string:
import '@/drizzle/envConfig';
import { defineConfig } from 'drizzle-kit';
 
export default defineConfig({
  schema: './drizzle/schema.ts',
  driver: 'pg',
  dbCredentials: {
    connectionString: process.env.POSTGRES_URL!,
  },
});
  1. Use the drizzle-kit CLI to generate your tables:
npx drizzle-kit push
  1. Lastly, create a new client to query your database:
# 
import '@/drizzle/envConfig';
import { drizzle } from 'drizzle-orm/vercel-postgres';
import { sql } from '@vercel/postgres';
import * as schema from './schema';
 
export const db = drizzle(sql, { schema });
 
export const getUsers = async () => {
  return db.query.users.findMany();
};

You can find more details in the Vercel documentation (https://vercel.com/docs/storage/vercel-postgres/using-an-orm#drizzle).

The error message suggests that the 'dialect' parameter is missing in your Drizzle configuration file. The 'dialect' parameter is used to specify the SQL dialect of your database.

However, in the provided knowledge sources, there's no mention of a 'dialect' parameter for Drizzle configuration. Instead, there's a 'driver' parameter which is set to 'pg' for PostgreSQL.

Here's an example of how the Drizzle configuration file should look like:

import '@/drizzle/envConfig';
import { defineConfig } from 'drizzle-kit';
 
export default defineConfig({
  schema: './drizzle/schema.ts',
  driver: 'pg',
  dbCredentials: {
    connectionString: process.env.POSTGRES_URL!,
  },
});

If you're still encountering issues, it might be a good idea to check the official Drizzle documentation or their GitHub repository for more information.

The error message suggests that the 'driver' value 'pg' is not acceptable and it expects 'd1-http' instead. This could be due to a version mismatch or a different configuration requirement.

However, in the provided knowledge sources, the 'driver' is indeed set to 'pg' for PostgreSQL. Here's the example from the knowledge sources:

import '@/drizzle/envConfig';
import { defineConfig } from 'drizzle-kit';
 
export default defineConfig({
  schema: './drizzle/schema.ts',
  driver: 'pg',
  dbCredentials: {
    connectionString: process.env.POSTGRES_URL!,
  },
});

If you're still encountering issues, it might be a good idea to check the official Drizzle documentation or their GitHub repository for more information. It's also possible that you might need to update your Drizzle package or there might be a conflict with another package.

To make the key field unique and have a default value of a random number with at least 6 characters, you can use the default method provided by drizzle-orm. However, drizzle-orm does not directly support generating random numbers as default values. You would need to handle the generation of the random number in your application logic when inserting new records.

Here's an example of how you might do this:

import { InferSelectModel, InferInsertModel } from "drizzle-orm";
import {
  jsonb,
  pgTable,
  serial,
  text,
  timestamp,
  uniqueIndex,
} from "drizzle-orm/pg-core";

export const ScrapeTable = pgTable(
  "scrapes",
  {
    id: serial("id").primaryKey(),
    key: text("key").unique().notNull(),
    data: jsonb("data").notNull(),
    createdAt: timestamp("createdAt").defaultNow().notNull(),
  },
  (scrape) => {
    return {
      uniqueIdx: uniqueIndex("unique_idx").on(scrape.key),
    };
  }
);

export type Scrape = InferSelectModel<typeof ScrapeTable>;
export type NewScrape = InferInsertModel<typeof ScrapeTable>;

When inserting a new record:

import { ScrapeTable, NewScrape } from './schema';

// Generate a random number with at least 6 characters
const randomNumber = Math.floor(100000 + Math.random() * 900000).toString();

const newScrape: NewScrape = {
  key: randomNumber,
  data: { /* your data here */ },
};

ScrapeTable.insert(newScrape);

In this example, a random number with at least 6 characters is generated and used as the key when inserting a new record.

Please note that this approach does not guarantee the uniqueness of the key field. If you need to ensure uniqueness, you might need to implement additional logic to check if a key already exists before inserting a new record.

#

If the key field in your schema is set to be unique and you try to insert a new record with a key that already exists in the database, the database will throw an error. This is because the unique constraint ensures that all values in a column are different.

In PostgreSQL, which is used in your case, the error would typically look something like this:

error: duplicate key value violates unique constraint "scrapes_key_key"

To handle this, you could implement a check before inserting a new record to see if a key with the same value already exists. If it does, you could then generate a new random number and try again. Here's a basic example:

import { ScrapeTable, NewScrape } from './schema';

async function insertScrape(data) {
  let key;
  let exists = true;

  while (exists) {
    // Generate a random number with at least 6 characters
    key = Math.floor(100000 + Math.random() * 900000).toString();

    // Check if a record with this key already exists
    exists = await ScrapeTable.findOne({ key });
  }

  const newScrape: NewScrape = {
    key,
    data,
  };

  return ScrapeTable.insert(newScrape);
}

In this example, a while loop is used to keep generating a new random number until a unique one is found. Please note that this is a simple example and might not be suitable for all use cases, especially if you have a large number of records in your database. In such cases, you might want to consider a different strategy for generating unique keys.

The error message suggests that the argument provided to the where clause is not of the correct type. The where clause expects an argument of type SQL<unknown> or a function that returns SQL<unknown>, but it's receiving a Promise<QueryResult<QueryResultRow>>.

In your case, you're using the sql template string function from @vercel/postgres inside the where clause. This function returns a SQL object, which should be compatible with the where clause.

However, the sql function is being used with an await keyword, which means it's being treated as a Promise. This is likely the cause of the error.

Here's how you can fix it:

const exists = await db
  .select()
  .from(ScrapeTable)
  .where(sql`${ScrapeTable.key} = ${sql.string(randomNumber)}`)
  .execute();

In this example, sql.string(randomNumber) is used to safely interpolate the randomNumber into the SQL query. The sql function from @vercel/postgres helps to prevent SQL injection attacks by safely escaping any user-provided values.

In Next.js 14, you can access the URL parameters in several ways depending on whether you're working with server components or client components.

Server Components:

For server components, you can access the route segments through the params prop and the URL search params through the searchParams prop for a given page.

Here's an example:

export default function Page({ params, searchParams }) {
  // params and searchParams are available here
}

Client Components:

If you're using client components, you can use the usePathname, useSelectedLayoutSegment, and useSelectedLayoutSegments hooks for more complex routes.

Here's an example:

import { usePathname, useSearchParams, useParams, useSelectedLayoutSegments } from 'next/app';

export default function Page() {
  const pathname = usePathname();
  const searchParams = useSearchParams();
  const params = useParams();
  const selectedLayoutSegments = useSelectedLayoutSegments();

  // pathname, searchParams, params, and selectedLayoutSegments are available here
}

Note: The usePathname hook gives you the current pathname, useSearchParams gives you the current query params, useParams gives you the dynamic params in the current URL, and useSelectedLayoutSegments gives you the active route segments (children) below the Layout it is called from.

To use server components with TypeScript in Next.js, you need to ensure you are using TypeScript 5.1.3 or higher and @types/react 18.2.8 or higher. If you are using an older version of TypeScript, you may see a 'Promise&lt;Element&gt;' is not a valid JSX element type error. Updating to the latest version of TypeScript and @types/react should resolve this issue.

Here's an example of how you might define a server component in TypeScript:

export default async function Page() {
  // Server Action
  async function create() {
    'use server'
 
    // ...
  }
 
  return (
    // ...
  )
}

In this example, the create function is marked as a server action using the 'use server' directive. The Page function is a server component because it's exported as the default export from a module and it's an async function.

You can also define server actions in a separate file and mark all exports of that file as server actions:

'use server'
 
export async function create() {
  // ...
}

In this example, the 'use server' directive is placed at the top of the file, marking all functions within the file as server actions.

In Next.js, the params and searchParams props in a page component are objects. The params object contains the dynamic route parameters from the root segment down to that page, while the searchParams object contains the search parameters of the current URL.

Here's how you might define their types in TypeScript:

type PageProps = {
  params: { [key: string]: string | string[] | undefined };
  searchParams: { [key: string]: string | string[] | undefined };
}

export default function Page({ params, searchParams }: PageProps) {
  // params and searchParams are available here
}

In this example, both params and searchParams are defined as objects with string keys and values that can be a string, an array of strings, or undefined.

Please note that the exact types for params and searchParams can vary depending on your application's routing structure and the specific URL parameters you're expecting.

Based on the information provided, it seems like you're trying to access query parameters from the URL in your Next.js application but you're getting an empty object instead.

In Next.js, you can access the query parameters using the searchParams prop in server components or the useSearchParams hook in client components.

Here's an example of how you might do this in a server component:

export default function Page({ searchParams }) {
  const key = searchParams.get('key');

  // ...
}

And here's how you might do it in a client component:

import { useSearchParams } from 'next/app';

export default function Page() {
  const searchParams = useSearchParams();
  const key = searchParams.get('key');

  // ...
}

In both of these examples, searchParams is an instance of the URLSearchParams interface, which provides methods to work with the query string of a URL.

If you're still getting an empty object, it could be due to a number of reasons. For example, you might be trying to access the query parameters too early in your component's lifecycle, before they've been populated. Or there might be an issue with how your application's routing is set up.

Without more information, it's hard to provide a more specific answer. If you could provide more details about your issue, such as the relevant parts of your code and the exact steps you're taking to reproduce the issue, it would be easier to help you.

The searchParams prop in Next.js is an object that contains the search parameters of the current URL. However, it can also be undefined in certain situations, such as during pre-rendering of a page that doesn't use getServerSideProps.

In TypeScript, you can represent this with the URLSearchParams | undefined type. This means searchParams can either be an instance of URLSearchParams or it can be undefined.

Here's how you might define the type of searchParams in your component:

type PageProps = {{
  searchParams: URLSearchParams | undefined;
}}

export default function Page({{ searchParams }}: PageProps) {{
  const key = searchParams?.get('key');

  // ...
}}

In this example, the ? operator is used to safely access the get method of searchParams even if searchParams is undefined. If searchParams is undefined, key will also be undefined.

The error message "TypeError: searchParams.get is not a function" suggests that searchParams is not an instance of URLSearchParams as expected. This could happen if searchParams is undefined or if it's an object of a different type.

In Next.js, searchParams should be an instance of URLSearchParams when it's provided to a server component as a prop or when it's returned by the useSearchParams hook in a client component.

Here's how you might use searchParams in a server component:

export default function Page({ searchParams }) {
  const key = searchParams.get('key');

  // ...
}

And here's how you might use it in a client component:

import { useSearchParams } from 'next/app';

export default function Page() {
  const searchParams = useSearchParams();
  const key = searchParams.get('key');

  // ...
}

If you're seeing the error message in one of these situations, it could be due to a bug or a misconfiguration in your application.

To debug the issue, you could add some logging to your component to check the value and type of searchParams:

console.log(searchParams);
console.log(typeof searchParams);

This will help you determine whether searchParams is undefined or an object of a different type.

The best file structure for a Next.js project can depend on the specific needs of your project. However, Next.js does provide some conventions for organizing your files and folders. Here's a basic overview:

  • app: This directory is used for the App Router. It contains files that define routes and handle metadata.
  • pages: This directory is used for the Pages Router. It contains files that define routes, including dynamic routes.
  • public: This directory is used for static assets that need to be served, such as images.
  • src: This is an optional directory that can be used to organize your application's source code.

In addition to these directories, there are several top-level files that are commonly used in a Next.js project:

  • next.config.js: This is the configuration file for Next.js.
  • package.json: This file manages project dependencies and scripts.
  • .env, .env.local, .env.production, .env.development: These files are used to define environment variables.
  • tsconfig.json or jsconfig.json: These files are used to configure TypeScript or JavaScript, respectively.

Here's an example of what this structure might look like:

/my-next-app
├── app
├── pages
├── public
├── src
├── next.config.js
├── package.json
├── .env
├── .env.local
├── .env.production
├── .env.development
├── tsconfig.json or jsconfig.json

For more complex applications, you might also have directories for components, hooks, utilities, and other types of code.
