ICU Demo Playground

This is a demo for playing with and exploring the ICU Message Format. It's a companion to our ICU Guide.

Running on StackBlitz

If you're accessing this demo on StackBlitz, it should run automatically. You might need to expand the built-in browser pane to get the best experience.

Running Locally

If you're running this locally, you'll need to have a recent version of Node.js installed.

With that in place, install the app dependencies and start the server:

npm install
npm run dev

A note on console errors

We're using the React Intl library to handle the ICU Message Format. But we're kind of hacking React Intl, which is really meant to be used as a behind-the-scenes i18n library. So you might see errors in the console. If the app is functioning correctly, you probably don't need to worry about them.
