React Library Boilerplate

This react library boilerplate uses the following:

• Typescript
• Rollup
• Prettier
• ESLint
• StyleLint
• Storybook
• SCSS
• Jest
• React Testing Library
• Semantic Release
• Github Actions

Setup

1. Edit the package.json file. Set you app's name, description, version, author, homepage, bugs, and repository fields with the correct information.
2. Run yarn to add all the project's dependencies.
3. You package.json file version should always be 0.0.0 since Semantic Release will automatically set this upon publishing.

Basic Folder Structure

├── .storybook
├── src
│   ├── components
|   |   ├── Example
|   |   |   ├── __tests__
|   |   |   |   ├── Example.test.tsx
|   |   |   ├── example.scss
|   |   |   ├── Example.stories.tsx
|   |   |   ├── Example.tsx
|   |   |   ├── index.ts
|   |   ├── index.ts
|   ├── index.ts
├── LICENSE
├── package.json
├── README.md

Add a new component

• add the new component directory in the src/components directory following this folder structure

├── MyComponent
|   ├── __tests__
|   |   ├── MyComponent.test.tsx
|   ├── MyComponent.scss
|   ├── MyComponent.stories.tsx
|   ├── MyComponent.tsx
|   ├── index.ts

Once you have created your new component make sure you have exported it in the src/components/index.ts file. Doing so allows the component to be compiled into the final bundle using rollup.

// src/components/index.ts
export * from './MyComponent';
export * from './SomeOtherComponent';

You can develop your new component using storybook as your playground. Once you have added the .stories.tsx file for you new component, you can run yarn storybook to start the service.

Tests

$ yarn test

With coverage

$ yarn test:coverage

Watch

$ yarn test:watch

Prettier

$ yarn format

Validate project formatting

$ yarn format:check

Lint

$ yarn lint

Storybook

$ yarn storybook

Building your library

$ yarn build

The build output will go into the dist directory

Github Actions

This project contains a github action workflow called ci.yaml. This workflow runs a job that will test, lint, and build the code. If the code passes and you are on the master branch it will also run the publish job to send the new version off to npm.

Publishing your Library on NPM

Once you have created an account on NPM create a publish key and add it to your github secrets as NPM_TOKEN Semantic Release will take care of the publishing and versioning for you via the .github/workflows/ci.yaml Publish job. In addition to publishing to NPM it will also create a new tag and release with commit messages in the repo.

Note: You will need to update the package.json name property with the correct name your library will be using on npm.

Committing Code Changes

The commit messages are critical for allowing the Semantic Releases to work correctly. We use the Conventional Commit commit message format. This is a small excerpt from the main docs:

The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.

The commit message should be structured as follows:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

The commit contains the following structural elements, to communicate intent to the consumers of your library:

1. fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in semantic versioning).
2. feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in semantic versioning).
3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in semantic versioning). A BREAKING CHANGE can be part of commits of any type.
4. types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others.
5. footers other than BREAKING CHANGE: <description> may be provided and follow a convention similar to git trailer format.

Additional types are not mandated by the Conventional Commits specification, and have no implicit effect in semantic versioning (unless they include a BREAKING CHANGE). A scope may be provided to a commit’s type, to provide additional contextual information and is contained within parenthesis, e.g., feat(parser): add ability to parse arrays.

Examples

Commit message with description and breaking change footer

feat: allow provided config object to extend other configs

BREAKING CHANGE: `extends` key in config file is now used for extending other config files

Commit message with ! to draw attention to breaking change

refactor!: drop support for Node 6

Commit message with both ! and BREAKING CHANGE footer

refactor!: drop support for Node 6

BREAKING CHANGE: refactor to use JavaScript features not available in Node 6.

Commit message with no body

docs: correct spelling of CHANGELOG

Commit message with scope

feat(lang): add polish language

Commit message with multi-paragraph body and multiple footers

fix: correct minor typos in code
