## Features

### :package: optimized bundler and transpiler

fast and minimal builds with [esbuild][1] (integrates with the build api for plugin support β€” say toodles πŸ‘‹πŸΎ to
transform api hacks! :wink:)

### :file_folder: bundleless dists

create bundleless distributions with file-to-file transpilation and static asset copying

### :relieved: esm friendly

create es modules + add file extensions to specifiers in modules ***and*** declaration files

### :bookmark_tabs: dts generation (`.d.cts`, `.d.mts`, `.d.ts`)

generate declarations for `.cjs`, `.cts`, `.js`, `.jsx`, `.mjs`, `.mts`, `.ts`, and `.tsx` files

### :dna: path alias support

resolve path aliases in `.cjs`, `.cts`, `.d.cts`, `.d.mts`, `.d.ts`, `.js`, `.jsx`, `.mjs`, `.mts`, `.ts`, and `.tsx`
files

## Install

This package is [ESM only][2].

```sh
yarn add -D @flex-development/mkbuild esbuild typescript
```

From Git:

```sh
yarn add -D @flex-development/mkbuild@flex-development/mkbuild esbuild typescript
```



See Git - Protocols | Yarn
Β for details on requesting a specific branch, commit, or tag.

## Use

```shell
mkbuild
```

Running the command above without a [build configuration](#configuration) file will create a bundleless [esm][3] build
with [declarations][4].

Files within the `src` directory will be transpiled or copied and output to `dist/**.{d.mts,mjs}`. Declaration files,
`dist/**.d.mts`, will be generated if `typescript` is installed. The original folder structure and extensions of copied
files will remain in tact.

### Configuration

Create `build.config.{cjs,cts,js,json,mjs,mts,ts}`:

```typescript
/**
* @file Build Config
* @module config/build
*/

import { defineBuildConfig } from '@flex-development/mkbuild'

export default defineBuildConfig({
// esbuild options; see https://esbuild.github.io/api/#build-api
sourcemap: 'external',
sourcesContent: false,
treeShaking: true,
tsconfig: 'tsconfig.build.json'
})
```

See all configuration options [here](src/interfaces/config).

Options common to build configs and [build entries](#configuring-build-entries) can be seen
[here](src/interfaces/options).

### Configuring Build Entries

```typescript
/**
* @file Build Config
* @module config/build
*/

import { defineBuildConfig } from '@flex-development/mkbuild'
import pkg from './package.json' assert { type: 'json' }

export default defineBuildConfig({
entries: [
{ dts: true, ignore: ['cli.ts'] }, // dist/**.{d.mts,mjs}
{ dts: true, ext: '.cjs', format: 'cjs', ignore: ['cli.ts'] }, // dist/**.{cjs,d.cts}
{ dts: 'only', ext: '.js', ignore: ['cli.ts'] }, // dist/**.d.ts
{ bundle: true, minify: true, source: 'src/cli.ts' } // dist/cli.mjs
],
platform: 'node',
sourcemap: 'external',
sourcesContent: false,
target: 'node' + pkg.engines.node.replace(/^\D+/, ''),
treeShaking: true,
tsconfig: 'tsconfig.build.json'
})
```

See all build entry options [here](src/interfaces/entry).

This package is fully typed with [TypeScript][5].
