Typescript, Rollup & Jest Starter

Starter project for building typescript projects using Rollup and Jest, React and React Test Library.

Inspiration

This project has been originally inspired, and thus forked from danielelder/typescript-rollup-jest. It shares the same ISC license but doesn't really share much code.

Usage

git clone --depth=1 git@github.com:derived-studio/rollup-ts-jest-react.git [yourProjectName]

Optional

To remove git history run from project folder

yarn
yarn detach

After detaching remove detach script from package.json and run

git add .
git commit "Initial commit"

Original features

• Statically typed build system for working with Typescript.
• Consistent code style with TSLint. - (removed)
• Dead code elimination
• Rollup for bundling
• Jest for unit testing and code coverage
• JSDOM for DOM based testing
• Flexible build configuration using environment variables
• Rapid development with automatic javascript building and browser hot reloading
• Easy debugging via VSCode integration

Fork features

• Uses typescript-eslint@3.7.1 instead of tslint
• Adds NPM distribution friendly output bundle files
• Distributes with TS definition files
• Includes an example build for naive greeter lib
• Improves jest configuration with initial jest setup
• Supports React and React-Dom
• Includes React Testing Library
• Git hooks for pre commit and pre push (with husky)
• Contains yarn detach script removing git history

Todo

• Clean up npm scripts (in progress)
• Restore serve files
• Include react in an example build

Scripts

• build - Builds the minified production bundle along with typescript modules
• test - Runs tests with code coverage report
• lint - Lints source files
• clean - removes dist folder
• serve - temporarily disabled Builds the development bundle, creates a local server and watches for changes

VS Code Integration

Tasks

Access the task list using shift+command+b (ctrl+shift+b in Windows) to run any of the above scripts.

Debugging

Unit tests can be debugged from within VS Code by placing a break point within your code and then launching the debugger.

• Jest - All - Runs all unit tests in debug mode
• Jest - Current - Runs the currently visible within VS Code editor

Coverage reports

The coverage reports are generated with Jest, and output to the /coverage folder.

To view the html report open: coverage/lcov-report/index.html
