TS-ESNode

[

This is a Node.JS Loader hook for Node.JS 13.9 or newer that transpiles TypeScript files into JavaScript using the getFormat, resolve, and transformSource hooks.

For Node.JS use npm install @k-foss/ts-esnode@latest

Usage

You should already have "type": "module" in your package.json

Install @k-foss/ts-esnode

Create a dev script in package.json

{
  "scripts": {
    "dev": "node --loader @k-foss/ts-esnode --loader extensionless ./src/index.ts",
  }
}

Now when you run npm run dev then you should be running your TypeScript source without having to transpile it while still retaining Node.JS ESModule & ESNext module mode.

Development

Setting up the development container

Follow these steps to open this project in a container:

1. If this is your first time using a development container, please follow the getting started steps.

2. To use this repository, you can either open the repository in an isolated Docker volume:

   • Press F1 and select the Remote-Containers: Open Repository in Container... command.
   • Enter K-FOSS/TS-ESNode
   • The VS Code window (instance) will reload, clone the source code, and start building the dev container. A progress notification provides status updates.

   Or open a locally cloned copy of the code:

   • Clone this repository to your local filesystem.

     • git clone https://github.com/K-FOSS/TS-ESNode.git

   • Open the project folder in Visual Studio Code.

     • code ./TS-ESNode

   • Reopen in Container

     • When you open the project folder in Visual Studio Code you should be prompted with a notification asking if you would like to reopen in container.

     Or manually reopen

     • Press F1 and select the "Remote-Containers: Open Folder in Container..." command.

TODO

• Worker Threads to avoid the TypeScript compiling affecting main thread.

• Performance improvements. (Better file/import finding.)

Testing

MUST HAVE NODE.JS v13.9 or newer

To try this out, clone repo

npm test

All tests are run on all commits and PRs.

Style

This project currently uses Prettier for code styling and automatic formatting. Prettier is run on every commit and pull request.

Linting

This project currently uses ESLint for code linting. ESLint is run on every commits and pull request.

Run ESLint

Dependency Management

Dependency Management for TS-ESNode is handled by automated pull requests created by Dependabot. When new released of development Dependencies are released Dependabot automatically creates a pull request for upgrading to the new version. If the created pull request passes the GitHub Actions testing, prettier/styling, and linting I will merge the pull request.

Releases

@K-FOSS/TS-ESNode uses semantic-release to intelligently automate the creation of a changelog, automatic package publish to NPM, along with creating a GitHub release and tag.

Semantic-Release is currently configured to analyze commits with the Conventional Commits preset to determine if and how the package version should be incremented and if a release should be published, which is why it is important to mantain the Conventional Commits spec for all commits.
