Developing

Here are some common scripts that you'll use to work with Chord's Next.js starter kit. As with any Next.js site, you can customize the scripts in package.json , but we'll describe the defaults here.

Starting a development server

yarn dev

Starts a Next.js server in development mode on http://localhost:3000. Hot reload is automatically enabled.

Running unit tests

yarn test            # runs all tests
yarn test:watch      # runs all tests in watch mode

This starter uses Jest, and react-testing-library to test React components. Running the tests in watch mode will re-run the tests any time a code change is detected.

Building a production site

yarn build

Builds the site for production.

Starting a production server

yarn start

Starts a production Next.js server on http://localhost:3000.

Optimizing a production site

The starter kit comes with @next/bundle-analyzer , which generates a visualization of the site's Javascript bundles. This can be helpful for understanding and optimizing bundle size.

yarn analyze

Runs next build and also opens a browser window with an interactive visualization of bundles.
