It’s awesome, isn’t it? For those who don’t know it, “Composer is a tool for dependency management in PHP”. For example, if you are going to use Slim Framework with Twig Templating system, just create a file named ‘composer.json’ in your working folder with the following contents


{
  "require": {
    "slim/slim": "2.*",
    "twig/twig": "1.*"
  }
}

Then run the following command:

$ composer install

It shall download them in a folder named vendor. Include the following code in your PHP script:

require 'vendor/autoload.php';

All libraries just work like magic 😀

Apparently Composer has some sort of repository where people upload their codes. I didn’t want to signup on their website to put my library. I’m sort of a control freak. I wanted to host my code on Github and yet people include my library in the Composer magic. Yes! Composer supports downloading from Github.


{
  "repositories": [
    {
      "url": "https://github.com/Nayar/mera-framework-php",
      "type": "git"
    }
  ],
  "require": {
    "slim/slim": "2.*",
    "twig/twig": "1.*",
    "meraframeworkphp": "*"
  },
}

However i was getting this error when I was initializing composer repositories.

Loading composer repositories with package information
Reading composer.json of meraframeworkphp (master)
Installing dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1
– The requested package meraframeworkphp could not be found in any version, there may be a typo in the package name.

Potential causes:
– A typo in the package name
– The package is not available in a stable-enough version according to your minimum-stability setting

Composer uses Git tags to actually find the repository version. Ran the following in my library git then it worked awesome:

$ git tag -a v1.0.0 -m 'First release'
$ git push origin v1.0.0
