Transcript

1. Managing Dependencies with Composer Chris Taggart / @christaggart Ottawa PHP Meetup / April 2015
3. Who has heard of composer?
4. Who is using it?
5. Managing Dependencies Sucks.
6. A lot.
7. But it doesn’t have to.
8. “Old way”
9. Go to the project’s site
10. Download a zip file or tarball
11. Unzip the file
12. Move it into some shared libraries folder
13. Scramble when a security fix is released
14. Repeat.
15. So much pain.
16. Enter Composer
18. Composer • Command-line utility with which you install packages. • Very similar to “npm” or Bundler • Works on *nix, OS X, Windows, PHP 5.3.2+
19. Packagist
20. composer.json { "require": { "monolog/monolog": "~1.13" }, "authors": [ { "name": "Chris Taggart", "email": "chris.taggart@canvaspop.com" } ] }
21. $ composer install
23. composer.lock
24. Additional Goodies
25. Autoloading ./vendor/autoload.php
 
 require ‘vendor/autoload.php';
26. Easy to use third-party code <?php $log = new Monolog\Logger('AppLog'); $log->pushHandler(new Monolog\Handler \StreamHandler('app.log', Monolog \Logger::WARNING)); $log->addWarning('Foo');
27. Or your own code { "autoload": { "psr-4": {"Acme\\": “src/library/"} } }
28. Get Composer `curl -sS https://getcomposer.org/installer | php` OR
 brew install composer or Windows Installer
