esw

esw is a JavaScript/TypeScript library build tool. It offers blazing fast performance utilizing esbuild, and requires zero configuration.

✨Passive usage

Infer build options from package.json by default. Ideally you don't need to write any configurations. Also support multiple entry points via glob syntax(eg. esw src/**/*.ts --outdir=dist) if necessary.

📦Optimized bundling

Driven by esbuild and only bundle codebase without any dependencies and peerDependencies by default.

Installation

npm i esw -D

Getting Started

3 steps to get started:

1. 🖊 declare main or module or both them in the package.json.

   {
     "name": "esw",
     "main": "dist/index.cjs.js",
     "module": "dist/index.esm.js"
   }
   

   ⚠️ The output format what module field refers to always be treated as esm^why.

2. 🏃‍ Run esw build from the working directory.

   esw build
   

3. 🏆 All transpiled products would be placed in the target output path which were inferred by esw.

   codebase root
    └─dist
       ├─index.cjs.js
       └─index.esm.js
