TypeScript project boilerplate with modern tooling, for Node.js programs, libraries and browser modules. Get started quickly and right-footed 🚀
- TypeScript 4
- Optionally esbuild to bundle for browsers (and Node.js)
- Linting with typescript-eslint (tslint is deprecated)
- Testing with Jest (and ts-jest)
- Publishing to npm
- Continuous integration (GitHub Actions / GitLab CI)
- Automatic API documentation with TypeDoc

# Clone the repository (you can also click "Use this template")
git clone https://github.com/metachris/typescript-boilerplate.git your_project_name
cd your_project_name
# Edit `package.json` and `tsconfig.json` to your liking
...
# Install dependencies
yarn install
# Now you can run various yarn commands:
yarn cli
yarn lint
yarn test
yarn build-all
yarn ts-node <filename>
yarn esbuild-browser
...- Take a look at all the scripts in
package.json - For publishing to npm, use
yarn publish(ornpm publish)
esbuild is an extremely fast bundler that supports a large part of the TypeScript syntax. This project uses it to bundle for browsers (and Node.js if you want).
# Build for browsers
yarn esbuild-browser:dev
yarn esbuild-browser:watch
# Build the cli for node
yarn esbuild-node:dev
yarn esbuild-node:watchYou can generate a full clean build with yarn build-all (which uses both tsc and esbuild).
package.jsonincludesscriptsfor various esbuild commands: see hereesbuildhas a--global-name=xyzflag, to store the exports from the entry point in a global variable. See also the esbuild "Global name" docs.- Read more about the esbuild setup here.
- esbuild for the browser uses the IIFE (immediately-invoked function expression) format, which executes the bundled code on load (see also evanw/esbuild#29)
You can write Jest tests like this:
import { greet } from './main'
test('the data is peanut butter', () => {
expect(1).toBe(1)
});
test('greeting', () => {
expect(greet('Foo')).toBe('Hello Foo')
});Run the tests with yarn test, no separate compile step is necessary.
- See also the Jest documentation.
- The tests can be automatically run in CI (GitHub Actions, GitLab CI):
.github/workflows/lint-and-test.yml,.gitlab-ci.yml - Take a look at other modern test runners such as ava, uvu and tape
You can auto-generate API documentation from the TypeScript source files using TypeDoc. The generated documentation can be published to GitHub / GitLab pages through the CI.
Generate the documentation, using src/main.ts as entrypoint (configured in package.json):
yarn docsThe resulting HTML is saved in docs/.
You can publish the documentation through CI:
