Create React App 2.0 has been released today, and it brings a year’s worth of improvements in a single dependency update.

While React itself doesn’t require any build dependencies, it can be challenging to write a complex app without a fast test runner, a production minifier, and a modular codebase. Since the very first release, the goal of Create React App has been to help you focus on what matters the most — your application code — and to handle build and testing setup for you.

Many of the tools it relies on have since released new versions containing new features and performance improvements:

Less than a year ago, we introduced Create React App as an officially supported way to create apps with zero configuration. The project has since enjoyed tremendous growth, with over 950 commits by more than 250 contributors.

Today, we are excited to announce that many features that have been in the pipeline for the last few months are finally released.

As usual with Create React App, you can enjoy these improvements in your existing non-ejected apps by updating a single dependency and following our migration instructions.

Newly created apps will get these improvements automatically.
