Notes

• This project is a repository template - click the Use this template button to use this starter codebase for your next project.

• Includes ESLint configured to work with TypeScript and Prettier.

• Includes tests with Jest - note that the babel.config.js and associated dependencies are only necessary for Jest to work with TypeScript.

• Recommended to use Visual Studio Code with the Format on Save setting turned on.

• Example icons courtesy of Heroicons.

• Microsoft Edge is not currently supported.

• Includes Storybook configured to work with React + TypeScript. Note that it maintains its own webpack.config.js and tsconfig.json files. See example story in src/components/hello/__tests__/hello.stories.tsx

• Includes a custom mock for the webextension-polyfill-ts package in src/__mocks__. This allows you to mock any browser APIs used by your extension so you can develop your components inside Storybook.
