Add support for Composer

[netweb]

This sounds like a good idea for bbPress also.

Via @DJPaul in ​#BuddyPress5928

I'd like to add Composer support to BuddyPress.

This would involve adding a JSON file into the root of /src/ (thus it would end up in a regular release, not just the dev SVN); it would contain pretty similar to info that our NPM package.json already has. Here's an example: ​https://github.com/markjaquith/WP-TLC-Transients/blob/master/composer.json

​#WP23912 is a discussion about Composer support in WordPress core; the issues covered in that topic don't affect us, but that ticket's description is helpful to read.

If we did this, once we have a release (because we want to use Composer with release versions), we can tell ​https://packagist.org/ about our new Composer support, which would allow someone to install BuddyPress by integrating with their own project/own site's composer.json (specifying BP as a package requirement). The easiest way to demo this is to install Composer and run a command like "composer require hyyan/logo-controller".

See BuddyPress ticket for patch and comments
