I want to fetch data from two API-endpoints in my api/route.ts. I need to send in an "carID" to pass along to the endpoint using a POST-request. How do I do:

Hi @grave ginkgo. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
To achieve this, you can follow these steps:
route.ts file:In the app/api/route.ts file, you can create two functions for fetching data from the two API endpoints using POST requests. Here's an example:
// app/api/route.ts
import type { NextApiRequest, NextApiResponse } from 'next'
async function fetchEndpoint1(carID: string) {
const res = await fetch('https://api.example.com/endpoint1', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ carID }),
})
return res.json()
}
async function fetchEndpoint2(carID: string) {
const res = await fetch('https://api.example.com/endpoint2', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ carID }),
})
return res.json()
}
export default async function handler(req: NextApiRequest, res: NextApiResponse) {
const carID = req.body.carID
// Initiate both requests in parallel
const endpoint1Data = fetchEndpoint1(carID)
const endpoint2Data = fetchEndpoint2(carID)
// Wait for the promises to resolve
const [data1, data2] = await Promise.all([endpoint1Data, endpoint2Data])
res.status(200).json({ data1, data2 })
}
In the example above, we're already running the queries in parallel using Promise.all().
To fetch the data in your client-side component, you can use the useEffect hook. Here's an example:
import { useState, useEffect } from 'react'
function CarData() {
const [data, setData] = useState(null)
const [isLoading, setLoading] = useState(false)useEffect(() => {
setLoading(true)
fetch('/api/route', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ carID: 'your_car_id' }),
})
.then((res) => res.json())
.then((data) => {
setData(data)
setLoading(false)
})
}, [])
if (isLoading) return <p>Loading...</p>
if (!data) return <p>No car data</p>
return (
<div>
{/* Render the data as needed */}
</div>
)
}
This example assumes that you have an API route at `/api/route` that corresponds to the `route.ts` file you created earlier. Replace `'your_car_id'` with the actual carID you want to pass to the API endpoints.

----------------------@vocal hazel How do I fetch data from a route I made? Do I have to make any kind of middleware? Use app-dir in NextJS13
vocal hazelBOT
Let me check the knowledge base for you. One moment! :books:
To fetch data from a route you created in Next.js 13, you don't necessarily need to use Middleware. You can simply use the fetch() function in your client-side component to make a request to your custom route. Here's an example of how to fetch data from a custom route:
app directory:// app/api/myRoute.ts
export async function GET(request: Request) {
// Fetch data or perform any required operations
const data = { message: 'Hello from myRoute' }
return new Response(JSON.stringify(data), {
headers: { 'Content-Type': 'application/json' },
})
}
import { useState, useEffect } from 'react'
function MyComponent() {
const [data, setData] = useState(null)
const [isLoading, setLoading] = useState(false)
useEffect(() => {
setLoading(true)
fetch('/api/myRoute')
.then((res) => res.json())
.then((data) => {
setData(data)
setLoading(false)
})
}, [])
if (isLoading) return <p>Loading...</p>
if (!data) return <p>No data</p>
return (
<div>
{/* Render the data as needed */}
<p>{data.message}</p>
</div>
)
}
In this example, we created a custom route called myRoute in the app/api directory and fetched data from it in a client-side component using the fetch() function and the useEffect hook. There's no need to create Middleware for this simple use case.

const onItemClick = (ship: ShipDataProps) => {
router.push(/ship/${ship.shipid});
};
Can I bring data along when useing routing?
vocal hazelBOT
Let me check the knowledge base for you. One moment! :books:
In Next.js, you can pass data to the target page using query parameters when using the router.push() method. In your case, you can pass the shipid as a query parameter like this:
const onItemClick = (ship: ShipDataProps) => {
router.push(`/ship?shipid=${ship.shipid}`);
};
Then, in the target page (e.g., pages/ship/[shipid].js), you can access the shipid from the query parameters using the useRouter hook:
import { useRouter } from 'next/router';
function ShipPage() {
const router = useRouter();
const { shipid } = router.query;
// Use the shipid to fetch data or perform any required operations
return (
<div>
{/* Render the ship data as needed */}
</div>
);
}
export default ShipPage;
shipid, it's recommended to use Next.js data fetching methods like getStaticProps and getStaticPaths for static generation or getServerSideProps for server-side rendering. You can find more information on data fetching in the Next.js documentation (https://nextjs.org/docs/basic-features/data-fetching).Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@vocal hazel the ship-object contains more information. is that lost? such as ship.imo
vocal hazelBOT
Let me check the knowledge base for you. One moment! :books:
Yes, in the example I provided, only the shipid is passed through the URL, and other information like ship.imo is not included. If you want to pass more data, you can add more query parameters to the URL. However, this approach is not ideal for passing large amounts of data or sensitive information.
Instead, you can use the shipid to fetch the complete ship data on the target page using Next.js data fetching methods like getStaticProps and getStaticPaths for static generation or getServerSideProps for server-side rendering.
For example, in your pages/ship/[shipid].js file, you can fetch the ship data based on the shipid:
import {{ useRouter }} from 'next/router';
function ShipPage({{ ship }}) {{
// Use the ship data as needed
return (
<div>
{{/* Render the ship data as needed */}}
</div>
);
}}
export async function getServerSideProps(context) {{
const shipid = context.params.shipid;
// Fetch the ship data based on the shipid
// Replace this with your actual API call or data fetching method
const ship = await fetchShipData(shipid);
return {{
props: {{ ship }},
}};
}}
export default ShipPage;
In this example, we're using getServerSideProps to fetch the ship data based on the shipid passed through the URL. This way, you can access all the ship data, including ship.imo, without passing it through the URL.

@vocal hazel Uncaught Error: The default export is not a React Component in page: "/ship/[ship]"
vocal hazelBOT
Let me check the knowledge base for you. One moment! :books:
It seems like you're encountering an error related to the default export in your /ship/[ship] page. The error message indicates that the default export is not a React Component.
To resolve this issue, make sure that you're exporting a valid React Component as the default export in your /ship/[ship] page. Here's an example of a correct default export for a React Component:
import React from 'react';
import { useRouter } from 'next/router';
function ShipPage() {
const router = useRouter();
const { shipid } = router.query;
// Use the shipid to fetch data or perform any required operations
return (
<div>
{/* Render the ship data as needed */}
</div>
);
}
export default ShipPage;
ShipPage function component and exporting it as the default export. Make sure your /ship/[ship] page follows a similar structure, and the default export is a valid React Component.Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@vocal hazel "use client"
export default function ShipPage({ params }) {
return (
<div className="bg-gray-100 w-full p-6 rounded-lg mb-8">
<h2 className="bg-white rounded-md text-lg font-bold py-2 text-center mb-4">
Hei
</h2>
</div>
);
};
Do I not export a valid component?

@vocal hazel When I run my next.js app, I get the error "Error: The default export is not a React Component in page: "/"" intermittently. Is there any solution?
