# TypeScript Boilerplate for 2022



[![Build and test status](https://github.com/metachris/typescript-boilerplate/workflows/Lint%20and%20test/badge.svg)](https://github.com/metachris/typescript-boilerplate/actions?query=workflow%3A%22Build+and+test%22)



TypeScript project boilerplate with modern tooling, for Node.js programs, libraries and browser modules. Get started quickly and right-footed 🚀



* [TypeScript 4](https://www.typescriptlang.org/)

* Optionally [esbuild](https://esbuild.github.io/) to bundle for browsers (and Node.js)

* Linting with [typescript-eslint](https://github.com/typescript-eslint/typescript-eslint) ([tslint](https://palantir.github.io/tslint/) is deprecated)

* Testing with [Jest](https://jestjs.io/docs/getting-started) (and [ts-jest](https://www.npmjs.com/package/ts-jest))

* Publishing to npm

* Continuous integration ([GitHub Actions](https://docs.github.com/en/actions) / [GitLab CI](https://docs.gitlab.com/ee/ci/))

* Automatic API documentation with [TypeDoc](https://typedoc.org/guides/doccomments/)

## Getting Started



```bash

# 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 

yarn esbuild-browser

...

```



* Take a look at all the scripts in [`package.json`](https://github.com/metachris/typescript-boilerplate/blob/master/package.json)

* For publishing to npm, use `yarn publish` (or `npm publish`)



## esbuild



[esbuild](https://esbuild.github.io/) is an extremely fast bundler that supports a [large part of the TypeScript syntax](https://esbuild.github.io/content-types/#typescript). This project uses it to bundle for browsers (and Node.js if you want).



```bash

# 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` includes `scripts` for various esbuild commands: [see here](https://github.com/metachris/typescript-boilerplate/blob/master/package.json#L23)

* `esbuild` 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](https://esbuild.github.io/api/#global-name).

* Read more about the esbuild setup [here](https://www.metachris.com/2021/04/starting-a-typescript-project-in-2021/#esbuild).

* 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](https://jestjs.io/docs/getting-started) [like this](https://github.com/metachris/typescript-boilerplate/blob/master/src/main.test.ts):



```typescript

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](https://jestjs.io/docs/getting-started).

* The tests can be automatically run in CI (GitHub Actions, GitLab CI): [`.github/workflows/lint-and-test.yml`](https://github.com/metachris/typescript-boilerplate/blob/master/.github/workflows/lint-and-test.yml), [`.gitlab-ci.yml`](https://github.com/metachris/typescript-boilerplate/blob/master/.gitlab-ci.yml)

* Take a look at other modern test runners such as [ava](https://github.com/avajs/ava), [uvu](https://github.com/lukeed/uvu) and [tape](https://github.com/substack/tape)



## Documentation, published with CI



You can auto-generate API documentation from the TypeScript source files using [TypeDoc](https://typedoc.org/guides/doccomments/). 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):



```bash

yarn docs

```



The resulting HTML is saved in `docs/`.



You can publish the documentation through CI:

* [GitHub pages](https://pages.github.com/): See [`.github/workflows/deploy-gh-pages.yml`](https://github.com/metachris/typescript-boilerplate/blob/master/.github/workflows/deploy-gh-pages.yml)

* [GitLab pages](https://docs.gitlab.com/ee/user/project/pages/): [`.gitlab-ci.yml`](https://github.com/metachris/typescript-boilerplate/blob/master/.gitlab-ci.yml)
