Extract, unminify, and beautify ("retidy") each file from a webpack/parcel bundle

⚠️ No Unit Tests, may have unexpected side effects ⚠️

npm install -g retidy

retidy \
    -i <bundle_file> \
    -o <out_dir> \
    -t <bundle_type> \
    -b <bundle_ast_reference>

see

retidy --help

import retidy from "retidy"

retidy(bundleCode[, options])

retidy(bundleCode: string, options?: Options): Promise<string[]>

If set options.writeFiles = true (by default), retidy will write extracted code files into the file system (under options.outDir directory, ./retidy-out/ by default).

see src/options.ts

import retidy from "retidy"
import fs from "fs"

const code = fs.readFileSync("path/to/webpack-bundle.js", "utf-8")

retidy(code, { type: "webpack", outDir: "./out/", bundleAstReferenceKeys: ["body", 0, "expression", "right"] })
