After a small discussion with @dunglas it appears it could be nice to display the Api-Platform's version in the Symfony's debug-bar.

Two solutions were talked about, adding a constant (:-1: because it needs to be maintained), or using ocramius/package-versions (this package is required-dev by symfony/orm).

This feature was proposed to Symfony but it was refused.

So here we are :-)

Output:

Note:
I was not sure about adding tests or not, as the outpu depends of a final class, that might exists or not

[dunglas]

Could you also add a test please?

It migh be enough to add it in the small tooltip opened on mouseover to save space in the toolbar ?

[dFayet]

Could you also add a test please?

@dunglas I've added a basic test, but as the data class is final + with a private construct I cannot mock it :(

@antograssiot I've moved it in the toolbar:

Personally I prefer it 10 times in the debug bar, you see it directly. (like Symfony does)

Thank you @dFayet!

@alanpoulain wouldn't it be more interesting to suggest https://github.com/composer/package-versions-deprecated for composer 1 & 2 compatibility?

[alanpoulain]

Not sure about this. If the user doesn't use PHP 7.4 or Composer 2, it will find this package anyway, don't you think?
And ocramius/package-versions is the original package, it makes sense to me to add it to the suggest list.

Indeed 👍
