If you use typescript, nodemon and ts-node for development.
You'll notice that it takes a while to recompile the code when it changes.

tsx is a Typescript execute which blazing fast ⚡️ with esbuild.

Installation

I prefer use pnpm but you can use npm, yarn, ...etc.

pnpm add -D tsx

Now you can uninstall nodemon and ts-node.

pnpm remove nodemon ts-node

Add script tsx watch [file/folder] in the package.json.

{
  "name": "use-tsx",
  "version": "1.0.0",
  "main": "index.ts",
  "scripts": {
    "dev": "tsx watch src",
  },
  "devDependencies": {
    "@types/node": "^18.7.18",
    "tsx": "^3.9.0",
    "typescript": "^4.8.3",
  }
}

Let's start.

pnpm dev
