Features

• Release CommonJS, ES Module, and UMD targets
• Easily configured through your package.json
• Optionally control Terser settings

Gotchas

Your code is prepared for release targets as written!

• Does not transpile your codeAKA – no Babel or Buble
• Does not inline dependenciesAKA – no Rollup or Webpack

If you need either of these, using microbundle comes highly recommended!

Seriously, I write wonky ES5 code in a single file...bundt only puts a name to the builder script I copy & paste between libraries.You are 99.9999% more likely to do better with microbundle and/or to not outgrow it.

Install

$ npm install --save-dev bundt

Usage

# display help text
$ bundt --help

# build with "lib/index.js" as your entry file
$ bundt lib/index.js

# build with "src/index.js" (default)
$ bundt

Configuration

Most configuration lives within your package.json file. The following keys are evaluated:

• "main" — the destination for your CommonJS fileDefaults to dist/{pkg.name}.js – always built!

• "module" — the destination for your ES Module fileA ESM file will not be built if unspecified!

• "unpkg" or "umd:main" — the destination for your UMD fileA UMD file will not be built if unspecified!

• "umd:name" or "name" — the globally exposed name for your UMD factoryYou should use an alternate umd:name if your name is not alphanumeric!

• "modes" — a map of "mode" names and their entry filesYour "default" mode will use the destinations defined above.All other modes replace dist with its name as the new directory.

• "terser" — custom Terser options for minificationAlternatively, you may use a .terserrc file~!
