Quick Start

Getting Started

Installation & Usage

In order to start using roblox-ts, you’ll need to have NodeJS and npm installed. You can download both from here.

Next, from your command line install roblox-ts: npm install -g roblox-ts

You can now run roblox-ts with the command rbxtsc -h.

Usage: rbxtsc [options]

  -w, --watch        enable watch mode
  -p, --project      project path
  -i, --includePath  folder to copy runtime files to
  --noStrict         disable diagnostic checks (faster, unsafe)
  --noInclude        do not copy runtime files
  --modulesPath      folder to copy modules to
  --noHeuristics     disables api restriction heuristics
  -v, --version      show version information
  -h, --help         show help

Project Folder Setup

We recommend that you write your TypeScript in VS Code for the best experience. However, other editors like Sublime Text and Atom are supported.

  1. Create a new folder and name it whatever you’d like. For example: MyCoolProject

  2. Run npm init -y inside of your folder. This will create your package.json file.

  3. Create a folder called src to contain your TypeScript files.

  4. Create a file named tsconfig.json in your project folder. The contents should look like this:

	"compilerOptions": {
		// required
		"allowSyntheticDefaultImports": true,
		"isolatedModules": true,
		"downlevelIteration": true,
		"module": "commonjs",
		"noLib": true,
		"strict": true,
		"target": "es6",
		"types": [ "rbx-types" ],

		// required, configurable
		"rootDir": "src",
		"outDir": "out",

		// optional
		"baseUrl": "src",
		"declaration": false,

		// optional, non-configurable
		"jsx": "react",
		"jsxFactory": "Roact.createElement"
	"typeAcquisition": {
		"enable": true

Do not change these values unless you know what you are doing!

5. Create a file for syncing your compiled .lua files to Roblox Studio. If you’re using Rojo, this should be a rojo.json file and look like:

	"name": "my-project-name",
	"servePort": 8000,
	"partitions": {
		"include": {
			"path": "include",
			"target": "ReplicatedStorage.RobloxTS.Include"
		"modules": {
			"path": "modules",
			"target": "ReplicatedStorage.RobloxTS.Modules"

You should add more partitions for the sub-folders of your out folder.

6. Run npm install rbx-types to install the Roblox API type definitions.

7. Start roblox-ts in watch mode rbxtsc -w

8. Run your sync program. If you’re using Rojo, this is rojo serve

9. Write code!

It is recommended that you peruse through the Usage and Guides sections as you get started.

roblox-ts is still in development and you may run into situations where invalid Lua is emitted. Please report these cases to us either by creating an issue or joining our Discord server (link above).
