Nano build

Build/bundle tools for ECMAScript, TypeScript, and JavaScript libraries. It's easy to use, doesn't require any setup, and adheres to best practices. It has no dependencies and uses esbuild for enhanced performance.

Installation

First, install @alwatr/nano-build as a development dependency:

yarn add -D @alwatr/nano-build

Usage

Add the following scripts to your package.json to use @alwatr/nano-build:

{
  "scripts": {
    "build": "nano-build --preset=module",
    "watch": "yarn run build --watch"
  }
}

Then run the following command to build your project:

yarn run build

Configuration

TypeScript types

import type {} from '@alwatr/nano-build';

Overwriting configuration

Add 'nano-build' field to your package.json for overwriting configuration:

{
  "nano-build": {
    "bundle": true
  },
  "nano-build-development": {
    "minify": false,
    "sourcemap": true
  },
  "nano-build-production": {
    "minify": true,
    "sourcemap": false
  }
}

Presets

Presets are predefined configurations that can be used to build your project. You can use the --preset flag to specify a preset.

yarn run build --preset=module

default

{
  entryPoints: ['src/*.ts'],
  outdir: 'dist',
  logLevel: 'info',
  target: 'es2020',
  minify: true,
  minifyWhitespace: true,

  define: {
    __package_name__: packageJson.name,
    __package_version__: packageJson.version,
    __dev_mode__: process.env.NODE_ENV !== 'production',
  },
  banner: {
    js: "/* __package_name__ v__package_version__ */"
  },
}

--preset=module

  sourcesContent: true
}

Note: default production overwrite options not applied.

--preset=module3

Builds multiple entry points in src directory for multiple exports module without bundling.

{

  ...(devMode ? developmentOverwriteOptions : productionOverwriteOptions),
}

Development overwrite

This preset is used when NODE_ENV is not set to production. It overwrites all other presets.

{
  sourcemap: true,
  sourcesContent: true,
}

you can also add nano-build-development field to your package.json for overwriting configuration.
