demin v0.2.2

Demin

Demin is a node CLI application for de-minifying (de-compiling) compiled AMD files. Demin does not guarantee that output code that executes identically to the source file; do not expect the code to export. The intent is to produce somewhat-readable code.

Example Transformation

define("module",["require","exports","tslib"],function(e,r,i){r.default=i.__assign({},{idk:!0,yo:void 0})})
define("another",["require","exports","module","lib/wrapper","vendor/wrapper"],function(e,r,i,o,d){r.default=o.wrap(d.wrap(i))})

becomes

/* module.js */
import * as Tslib from 'tslib'
var P = {
  idk: true,
  yo: undefined,
}
exports.default = Tslib.__assign({}, P)

/* another.js */
import * as Wrapper from 'lib/wrapper'
import * as Wrapper1 from 'vendor/wrapper'
import * as Module from 'module'
exports.default = Wrapper.wrap(Wrapper1.wrap(Module))

Features

Current features:

• change required module names from define to ES6 module import statements
• change !0, !1, and void 0 to their typical identifiers true, false, and undefined
• run Prettier

Currently-planned features:

• get nearly all require calls converted to import statements
• change exports.default = and exports.name = calls to ES6 module export default and export const calls.
• remove the comma operator when possible (e.g. return a(), b(), c(); → a(); b(); return c();)
• change *.createElement calls to JSX syntax

Installation

npm install -g demin

This installs demin to your $PATH, so you can call it like the example usage below.

Uninstall

npm uninstall -g demin

Usage

Suggested usage:

demin -i file.js -o output --clean --prettier

(note: --prettier is pretty slow if you have many output files or large files)

Minimal usage:

demin -i file.js -o output

All options:

See demin --help for all options

(you probably don't want to mix --dry and --quiet because that's useless)
