Composer vs. Yarn

It can/must be used for any size of software project. Not only provides the best way to control depencies, but also has a strong worldwide community of developers.

There is really no real reason why not to use Yarn today. It's much faster than npm, and you will need a dependency management system anyway. The only thing that might be missing is the fact that it doesn't come natively with NodeJS, and you have to install it yourself. I'd like to see the NodeJS ecosystem include Yarn by default.

• Controlling dependencies
• Fast dependency resolver
• Easy to use dependency injection

• Package management
• Speed of download compared to npm
• Moduel version control

• Sometimes a bit slow, but v2 made a lot of improvements on that
• If everything is modular, setting up a local dev environment is a bit trickier than having everything in the same repo
• Might be hard to adopt with some frameworks which have not fully embraced it, like Wordpress

• Rarely, some server connection error appear, while npm works alright.
• Sometimes, deleting the whole vendor directory is the best solution to solve weird issues.
• You still might need npm to install Yarn.

If you're familiar with npm or Yarn, you'll feel right at home with composer. The work in pretty much the same way. You can use a composer.json file in your repo to reference specific version of public community modules, and enterprise internal ones. You can also hook some scripts that you would want to execute, like for testing, building your code ...

Compared to npm, Yarn is a clear winner here. npm does not look to be getting any improvements recently. And it's much much slower to run when installing project dependencies. This has a clear impact on the developer productivity but also makes deployments slower. So Yarn is still a much superior choice.

• Helped us reduce the TTM of our ecommerce factory by about 40% since we adopted it
• Code re-usability became the norm, and thus much shorter development cycles
• New websites go live much faster, and thus cost way less money to make when reusing composer modules (SSO, CRM integration, modules to call Internal APIs ...)

Incentivized

• Deployments happen much faster.
• Building and testing our apps is much more streamlined and efficient.
• Makes it easier to write reusable code.
