rescript-generated-js-diff

Small CLI to zip the generated JS files of a ReScript project. Useful for sharing or inspecting diffs of compiler output.

How it works

• Config discovery: reads rescript.json or bsconfig.json to find sources.
• File selection: collects files with the configured suffix (default: .bs.js; respects suffix if set, e.g. .res.mjs).
• Output: creates a zip archive in the target project directory.

Install

npm install

Run

node src/RescriptGeneratedJsDiff.res.mjs <base-dir> [out-file]

Examples:

# Zip generated JS in the current project (writes ./diff.zip)
node src/RescriptGeneratedJsDiff.res.mjs .

# Custom output path
node src/RescriptGeneratedJsDiff.res.mjs . ./out/generated.zip

Notes

• Exits with code 1 if no files with the target suffix are found.
• To rebuild .res.mjs from source, use: npm run res:build (and npm run res:dev to watch).
