Error Handling in React 16	gaearon

As React 16 release is getting closer, we would like to announce a few changes to how React handles JavaScript errors inside components. These changes are included in React 16 beta versions, and will be a part of React 16.

Behavior in React 15 and Earlier

In the past, JavaScript errors inside components used to corrupt React’s internal state and cause it to emit cryptic errors on next renders. These errors were always caused by an earlier error in the application code, but React did not provide a way to handle them gracefully in components, and could not recover from them.

In production, it is recommended to minify any JavaScript code that is included with your application. Minification can help your website load several times faster, especially as the size of your JavaScript source code grows.

Here's one way to set it up:

1. Install Node.js
2. Run npm init -y in your project folder (don't skip this step!)
3. Run npm install terser

Now, to minify a file called like_button.js, run in the terminal:

# Installing gofabric8
curl -sS https://get.fabric8.io/download.txt | bash
export PATH=$PATH:$HOME/.fabric8/bin
# Starting the cluster
gofabric8 start
gofabric8 start --vm-driver=virtualbox
gofabric8 start --memory=6000 --cpus=2
# Validating your cluster
gofabric8 validate
# Using OpenShift
