Hi @jagged dew. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

Based on the information provided in the extracts, it seems like you're trying to set a cookie in a Next.js API route. You can set cookies inside an API Route using the setHeader method on the response. Here's an example from the Next.js documentation (https://nextjs.org/docs/pages/building-your-application/data-fetching/forms-and-mutations#setting-cookies):

import type { NextApiRequest, NextApiResponse } from 'next'
 
export default async function handler(
 req: NextApiRequest,
 res: NextApiResponse
) {
 res.setHeader('Set-Cookie', 'username=lee; Path=/; HttpOnly')
 res.status(200).send('Cookie has been set.')
}

However, it's important to note that cookies are sent with every HTTP request to the server, not just specific routes. The Path attribute in a cookie determines the URL path that must exist in the requested URL in order for the Cookie header to be sent in the request. If you set Path=/users, the cookie will be sent for all requests that start with /users.

In your case, you're trying to set the cookie to be sent only to <http://localhost:3001/users/.> If your Next.js application is running on a different domain or port (e.g., localhost:3000), the cookie won't be sent to localhost:3001 due to the Same-Origin Policy (https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy).

If you want to send the cookie only when making requests to <http://localhost:3001/users/,> you might need to set the cookie in the browser when making the request to that specific URL, rather than setting it server-side in Next.js. However, this approach might not be ideal due to security concerns, as it exposes the refresh token to the client-side JavaScript.

#

Please note that the cookies function you're using in your code is not mentioned in the provided extracts, so I can't provide specific guidance on its usage.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@solid ingot What I am doing is not a nextjs api route, is it just a server action on a action.ts

How do it do it then ? a refresh token should not be sent on every request for security reasons, I would like to send it only on a certain path.

Based on the information provided in the extracts, it seems like you're trying to set a cookie in a server-side function in Next.js. However, setting cookies is typically done in the context of an HTTP response, which is not directly available in a server-side function that's not an API route.

If you want to set a cookie that's only sent for requests to a specific path, you can do so by setting the Path attribute when you set the cookie. However, this will only affect when the cookie is sent from the client to the server, not when it's set on the server.

Here's an example of how you might set a cookie in an API route:

import type { NextApiRequest, NextApiResponse } from 'next'
 
export default async function handler(
 req: NextApiRequest,
 res: NextApiResponse
) {
 res.setHeader('Set-Cookie', 'username=lee; Path=/users; HttpOnly')
 res.status(200).send('Cookie has been set.')
}

In this example, the cookie will only be sent for requests that start with /users.

However, if you're trying to set the cookie in a server-side function that's not an API route, you might need to return the token from that function and then set the cookie in the API route that calls the function.

Please note that the cookies function you're using in your code is not mentioned in the provided extracts, so I can't provide specific guidance on its usage.

Using the app router of nextjs 14, how can I use route handler to handle my fetch to my external API (localhost/auth/login)
route.ts:
export async function POST(request: Request) {
console.log(request)
}

action.ts:

export async function login(formData: FormData) {
try {
const email = formData.get('email')
const password = formData.get('password')
const response = await fetch('api/login', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({ email, password })
})
const data = await response.json()
console.log(data)
console.log(data.tokens.refreshToken)
return data;
} catch (error) {
console.error(error)
console.log("something went wrong")
}
}

authprovidex.tsx:

export function AuthProvider({ children }: AuthProviderProps) {
const [user, setUser] = useState(null);
const [accessToken, setAccessToken] = useState(null);
const [refreshToken, setRefreshToken] = useState(null);

const loginUser = async (formData: FormData) => {
    const data = await login(formData);
    setUser(data.user)
    setAccessToken(data.tokens.accessToken)
    setRefreshToken(data.tokens.refreshToken)
}

return (
    <AuthContext.Provider value={{ refreshToken, accessToken, user, login: loginUser }}>
        {children}
    </AuthContext.Provider>
);

}

In Next.js 14, you can use Route Handlers to handle requests to your external API. Route Handlers allow you to create custom request handlers for a given route using the Web Request and Response APIs.

In your case, you can create a Route Handler for the /api/login route and use it to handle the POST request. Here's an example of how you might do this:

// app/api/login.ts
import type { Request } from 'next/app'

export async function POST(request: Request) {
  const { email, password } = await request.json()

  const response = await fetch('<http://localhost:3001/auth/login',> {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ email, password })
  })

  const data = await response.json()

  return new Response(JSON.stringify(data), { status: response.status })
}

In this example, the Route Handler receives the request, extracts the email and password from the request body, and then makes a fetch request to the external API. It then returns the response from the external API as the response to the original request.

Then, in your login function, you can make a fetch request to the Route Handler instead of the external API:

// action.ts
export async function login(formData: FormData) {
  try {
    const email = formData.get('email')
    const password = formData.get('password')
    const response = await fetch('/api/login', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ email, password })
    })
    const data = await response.json()
    console.log(data)
    console.log(data.tokens.refreshToken)
    return data;
  } catch (error) {
    console.error(error)
    console.log("something went wrong")
  }
}
#

This way, the actual fetch request to the external API is handled server-side by the Route Handler, and the client-side code only needs to interact with the Route Handler.

Please note that this is a basic example and you might need to adjust it to fit your specific needs. For example, you might need to handle errors and edge cases, and you might want to add authentication and authorization checks in the Route Handler.

For more information on Route Handlers, you can refer to the Next.js documentation (https://nextjs.org/docs/app/building-your-application/routing/route-handlers).

The error message TypeError: Failed to parse URL from /api/login suggests that the fetch function is unable to parse the URL /api/login. This is likely because fetch expects a fully qualified URL (including the protocol, hostname, and port), but /api/login is a relative URL.

In a Next.js application, fetch is a server-side function, so it doesn't have the concept of a "current" URL like it would in a browser. Therefore, you need to provide the full URL when making a fetch request.

If your Next.js application is running on <http://localhost:3000,> you would change the fetch URL to <http://localhost:3000/api/login.>

Here's how you might modify your login function:

// action.ts
export async function login(formData: FormData) {{
  try {{
    const email = formData.get('email')
    const password = formData.get('password')
    const response = await fetch('<http://localhost:3000/api/login',> {{
      method: 'POST',
      headers: {{
        'Content-Type': 'application/json'
      }},
      body: JSON.stringify({{ email, password }})
    }})
    const data = await response.json()
    console.log(data)
    console.log(data.tokens.refreshToken)
    return data;
  }} catch (error) {{
    console.error(error)
    console.log("something went wrong")
  }}
}}

The second error TypeError: Cannot read properties of undefined (reading 'user') is likely because the data object returned from the login function is undefined. This could be because the fetch request failed, or because the server didn't return the expected data. You might want to add some error checking to handle this case.

import { cookies } from "next/headers"

export async function POST(request: Request) {
console.log(request)
const { email, password } = await request.json()

const response = await fetch('http://localhost:3001/auth/login', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json'
    },
    body: JSON.stringify({ email, password })
})

const data = await response.json()
const refreshToken = data.tokens.refreshToken
cookies().set('refreshToken', refreshToken)

// add the cookie to the response
return new Response(JSON.stringify(data), { status: response.status })

}

It is not setting my cookie

#

In your code, you're trying to set a cookie using the cookies().set() function. However, this function is not directly setting the cookie on the response. Instead, it's setting the cookie on a cookies object that's not connected to the response.

To set a cookie on the response, you need to use the Set-Cookie header on the response object. Here's how you might modify your code:

import { cookies } from "next/headers"

export async function POST(request: Request) {
    console.log(request)
    const { email, password } = await request.json()

    const response = await fetch('<http://localhost:3001/auth/login',> {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ email, password })
    })

    const data = await response.json()
    const refreshToken = data.tokens.refreshToken

    // create a new response
    const nextResponse = new Response(JSON.stringify(data), { status: response.status })

    // set the cookie on the response
    nextResponse.headers.append('Set-Cookie', `refreshToken=${refreshToken}; Path=/; HttpOnly`)

    return nextResponse
}

In this example, I'm creating a new Response object and setting the Set-Cookie header on it to set the cookie. The Set-Cookie header value is a string that specifies the cookie name, value, and attributes. In this case, I'm setting the refreshToken cookie with the value of refreshToken, and I'm setting the Path attribute to / and the HttpOnly attribute to make the cookie inaccessible to JavaScript.

Please note that this is a basic example and you might need to adjust it to fit your specific needs. For example, you might want to set other cookie attributes for security reasons, like Secure and SameSite.
