Development

Getting Started

This project uses Node.js as defined by .nvmrc. You can use nvm to install the correct version:

nvm install $(cat .nvmrc)

Install dependencies with npm which should also install git hooks with husky.

npm install

You can verify husky installed correctly by verifying the output of git config core.hooksPath is .husky. If this didn't work for some reason, you can run npx husky install.

Testing

You can run all linters, tests, and builds like CI with npm test.

Unit

Jest is used as the testing framework providing the runner, structure, assertions, mocks, and coverage among other features.

npm run test:unit

Linting

You can run all linters with npm run lint.

ESLint

ESLint analyzes the code to find and fix problems. We use eslint-plugin-square for out-of-the-box configuration.

npm run lint:eslint
Fixing warnings and errors automatically

ESLint can sometimes fix warnings and errors automatically for you with its --fix option.

npm run lint:eslint --fix

Prettier

Prettier is an opinionated code formatter. We use @square/prettier-config for those opinions.

npm run lint:prettier
Fixing code style issues

If after running npm run lint:prettier you get a warning like, "Code style issues found in the above file(s). Forgot to run Prettier?", you can have Prettier fix them.

npm run lint:prettier:fix

Building

TypeScript is used to build the module that is published to npm.

npm run build

Conventional Commits

Conventional Commits are used for commit messages which allows us to automate changelogs and releases that dovetail with SemVer.

Continuous Integration

GitHub Actions is used for our CI/CD workflows. See .github/workflows for details.
