Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

• Always add tests
• Keep backward compatibility (see https://symfony.com/bc).
• Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
• Features and deprecations must be submitted against the 7.4 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Hi,This is my first PR to Symfony. I’ve added support for application/x-ndjson MIME type using the internal script. Let me know if I need to improve anything — happy to learn and contribute more!

@Aryanverma19 I couldn't find x-ndjson in the database used to generate the types map... and it didn’t appear when I ran the script locally either.

Is it possible you added it manually? If so, just a heads-up: that might not be the best idea, since it will be removed each time the file is regenerated.

The best approach would be to wait until it’s properly integrated in an "official" database... but as far as I can see, that process hasn’t started yet.

So, as @MatTheCat mentioned in the original issue, you can add it directly in your app for now as a temporary workaround.
