TypeScript Boilerplate for 2021
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
See also the introduction blog post: Starting a TypeScript Project in 2021.
Getting Started
# 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
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:watch
You can generate a full clean build with yarn build-all
(which uses both tsc
and esbuild
).
package.json
includesscripts
for various esbuild commands: see hereesbuild
has a--global-name=xyz
flag, 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 https://github.com/evanw/esbuild/issues/29)
Tests with Jest
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
Documentation, published with CI
You can auto-generate API documentation from the TyoeScript 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 docs
The resulting HTML is saved in docs/
.
You can publish the documentation through CI:
