Brew Images - React

Generates responsive image URLs for various screen sizes and automatically lazy-loads them!

Commands

The recommended workflow is to run TSDX in one terminal:

yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

To do a one-off build, use yarn build.

To run tests, use yarn test.

To publish to NPM, run yarn publish.

Jest

Jest tests are set up to run with yarn test. This runs the test watcher (Jest) in an interactive mode. By default, runs tests related to files changed since the last commit.

Rollup

TSDX uses Rollup v1.x as a bundler and generates multiple rollup configs for various module formats and build settings. See Optimizations for details.

TypeScript

tsconfig.json is set up to interpret dom and esnext types, as well as react for jsx.

Optimizations

Please see the main tsdx optimizations docs. In particular, know that you can take advantage of development-only optimizations:

// ./types/index.d.ts
declare var __DEV__: boolean;

// inside your code...
if (__DEV__) {
  console.log('foo');
}

Testing Locally

Use yarn link to enable testing this package locally within another node project. Each time you make a change, you'll need to run yarn build for those changes to be propogated to the test environment.
