Walkthrough

The pull request modifies the askForTalawaApiUrl function by updating the default value of the endpoint input to remove the trailing slash. Additionally, the askAndUpdateTalawaApiUrl function is enhanced to trim any trailing slashes from the endpoint obtained from askForTalawaApiUrl. These changes ensure a consistent URL format for users during setup without altering the overall functionality.

Changes

8-9: LGTM! Good UX improvement to prevent configuration errors.

The changes effectively address the root cause of the 404 issue by:

  1. Explicitly warning users about trailing slashes in the prompt
  2. Setting a correct default value without a trailing slash

This is a simple but effective solution that will help prevent configuration errors.

However, we could further improve the user experience with input validation.

Consider adding validation to automatically trim any trailing slashes from the user input:

 export async function askForTalawaApiUrl(): Promise<string> {
   const { endpoint } = await inquirer.prompt<{ endpoint: string }>([
     {
       type: 'input',
       name: 'endpoint',
       message: 'Enter your talawa-api endpoint:(omit the trailing "/")',
       default: 'http://localhost:4000/graphql',
+      validate: (input: string) => {
+        return true;
+      },
+      filter: (input: string) => input.replace(/\/+$/, ''),
     },
   ]);
   return endpoint;
 }

This would ensure that even if users accidentally include trailing slashes, they will be automatically removed.

Make the code trim the trailing slash instead. The user experience must be improved, not just the messaging

  1. Also, with this fix, will the user be able to login?
  2. If not, then more work will need to be done.

I think there wont be any issue with graphql after this . Will have to check db operations and authorization part if both are fine then it should work

50-52: LGTM! Consider enhancing the trailing slash handling.

The implementation successfully addresses the 404 error issue. However, consider making it more robust:

-          if (endpoint.endsWith('/')) {
-            endpoint = endpoint.slice(0, -1);
-          }
+          // Normalize the endpoint URL by removing trailing slashes to prevent 404 errors
+          endpoint = endpoint.replace(/\/+$/, '');

This enhancement:

  • Handles multiple consecutive trailing slashes
  • Uses a more idiomatic approach with regex
  • Adds a descriptive comment explaining the purpose

50-52: Verify URL transformations after trailing slash removal.

Please ensure that WebSocket and Docker URL transformations work correctly with the modified endpoint. Test the following scenarios:

Test cases to verify:

  1. HTTP → WS transformation: http://localhost:4000/graphqlws://localhost:4000/graphql
  2. HTTPS → WSS transformation: https://localhost:4000/graphqlwss://localhost:4000/graphql
  3. Docker URL transformation: http://localhost:4000/graphqlhttp://host.docker.internal:4000/graphql
✅ Verification successful

URL transformations are correctly ordered and safe

The trailing slash removal is performed before URL validation and transformations, ensuring consistent behavior across all URL operations:

  • URL validation occurs immediately after slash removal
  • WebSocket protocol transformation only affects the protocol part
  • Docker URL transformation only replaces the hostname
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify URL handling patterns in the codebase

# Check for other URL transformations that might be affected
echo "Checking for URL transformation patterns..."
rg -n "\.replace\(.*http.*\)" --type ts

# Check for other endpoint URL handling
echo "Checking for endpoint URL handling..."
rg -n "endpoint.*endsWith|endpoint.*slice|endpoint.*replace" --type ts

# Check for URL validation patterns

@Nikhilh26 the title of the pr should reflect the original issue to avoid confusion. Does this solve the issue with login?

The issue with login is not only in admin but in API as well . What this PR resolves is the thing that even after having a running
talawa-api the talawa-admin wasnt able to find it . As for login issues , I am working on it

http://localhost, https://localhost and http://127.0.0.1:8080, in devcontainer environment talawa api is exposed at these addresses if the default environment variables are used

http://localhost and https://localhost, in local production environment talawa api is exposed at these addresses if the default environment variables are used

all this information can be inferred from the environment variables defined in /envFiles directory of talawa api

What changes are therefore required in this PR?

Would Admin would still need to trim the / ?

Probably nothing to do with the leading slash /. The correct url to talawa api needs to be provided using some environment variable from what I can guess.

Edit: related to this probably: https://fastify.dev/docs/latest/Reference/Server/#ignoretrailingslash
