Build your Typescript Node.js projects using blazing fast esbuild.

Since esbuild can build large typescript node projects in subsecond speeds, this is quite useful for development builds too if you want to stick with tsc for production builds.

Please note this library doesnt do typechecking. For typechecking please continue to use tsc.

esbuild-node-tsc reads the tsconfig.json and builds the typescript project using esbuild. esbuild is the fastest typescript builder around. It also copies the non ts files such as json, graphql files, images,etc to the dist folder. If the assets are not copied correctly check the configuration guide below.

npm install --save-dev esbuild-node-tsc

npx esbuild-node-tsc

or use the short form.

npx etsc

Additionally, you can add it to your build scripts

{
  "name": "myproject",
  "version": "0.1.0",
  "scripts": {
    "dev": "etsc" 
  }
}

Then just run

npm run dev

Since esbuild can build large typescript projects in subsecond speeds you can use this library instead of ts-node-dev or ts-node which usually slow down when project scales.

To achieve live reloading:

npm install --save-dev nodemon esbuild-node-tsc

Then add the following script to package.json

{
  "name": "myproject",
  "version": "0.1.0",
  "scripts": {
    "dev": "nodemon"
  }
}

And add a nodemon.json

{
  "watch": ["src"],
  "ignore": ["src/**/*.test.ts"],
  "ext": "ts,mjs,js,json,graphql",
  "exec": "etsc && node ./dist/index.js",
  "legacyWatch": true
}

Finally run

npm run dev

By default esbuild-node-tsc should work out of the box for your project since it reads the necessary configuration from your tsconfig.json

But if things are not working as expected you can configure esbuild-node-tsc by adding etsc.config.js along side tsconfig.json.

Example etsc.config.js

module.exports = {
  outDir: "./dist",
  esbuild: {
    minify: false,
    target: "es2015",
  },
  assets: {
    baseDir: "src",
    filePatterns: ["**/*.json"],
  },
};

All of the above fields are optional
