26. ACHTUNG, ACHTUNG.
27. www.easybib.com jobs@imagineeasy.com Repositories • Repositories are not inherited. • Put open source code on packagist, or get satis.
28. www.easybib.com jobs@imagineeasy.com Consuming • There are a lot, lot more options. • Check http://getcomposer.org/
29. www.easybib.com jobs@imagineeasy.com Installing cd awesome-application
 curl -sS http://getcomposer.org/installer |php
 ./composer.phar install
30. www.easybib.com jobs@imagineeasy.com What else? • Update your dependencies. • Search for dependencies. • Development dependencies. • Classmap and PSR-0 autoloaders. • “help”
31. Breath.
32. www.easybib.com jobs@imagineeasy.com One more thing Do you know composer’s global command?
33. www.easybib.com jobs@imagineeasy.com Go PEAR! Go global! •$COMPOSER_HOME/composer.json •./composer.phar global install
34. www.easybib.com jobs@imagineeasy.com Satis Your own private packagist.org.
35. Because what could go wrong?
36. www.easybib.com jobs@imagineeasy.com Things that will go wrong • Github is down. • Packagist is down. • Internet is slow. • Internet doesn’t work. • Tags get deleted. (cc fabpot :)
37. Own your availability!
38. www.easybib.com jobs@imagineeasy.com Captain Obvious Your proprietary code is private.
39. www.easybib.com jobs@imagineeasy.com Setup ./composer.phar \
 create-project \
 composer/satis \
 --stability=dev \
 --prefer-dist
40. www.easybib.com jobs@imagineeasy.com satis.json {
