Building locally

  • Install Node.js version 10
    • If you are using nvm (recommended) running nvm use will automatically choose the right node version for you.
  • Install Yarn
  • Install dependencies: yarn
  • Build the project to the ./dist/ folder with yarn dist.
  • Optionally, to start a development build (e.g. with logging and file watching) run yarn start instead.
    • To start the React DevTools and Redux DevTools Extension
      alongside the app, use yarn start:dev.
      • React DevTools will open in a separate window; no browser extension is required
      • Redux DevTools will need to be installed as a browser extension. Open the Redux Remote Devtools to access Redux state logs. This can be done by either right clicking within the web browser to bring up the context menu, expanding the Redux DevTools panel and clicking Open Remote DevTools OR clicking the Redux DevTools extension icon and clicking Open Remote DevTools.
        • You will also need to check the "Use custom (local) server" checkbox in the Remote DevTools Settings, using the default server configuration (host localhost, port 8000, secure connection checkbox unchecked)

Uncompressed builds can be found in /dist, compressed builds can be found in /builds once they're built.
