Package.json Generator

Package.json Generator

Create a valid package.json from a structured form instead of memorizing every field. Set the package name, version, license, module system (ESM or CommonJS), Node engine, scripts, and dependencies, and the tool produces a clean, properly ordered manifest you can drop straight into a project.

Unlike a formatter that reshuffles an existing file, this generator builds the manifest from scratch and skips empty fields, so you get a minimal, publishable file that already follows the conventions npm uses for npm init.

How to Use

1. Enter the package name, version, and (optional) description and author.
2. Pick a license and choose ES Modules or CommonJS for the module system.
3. Set the entry file (e.g. index.js) and an engines.node range like >=18.
4. Fill in the scripts you actually use (dev, build, test, start) — leave fields blank to omit them.
5. Add dependencies and devDependencies as name@range, one per line or comma-separated.
6. Choose your indent (2 spaces, 4 spaces, or tab) and copy or download the generated package.json.

Features

• Form-driven – No need to remember the exact field names or order; common keys are filled in for you.
• ESM or CommonJS – Toggle the module system and the tool sets "type": "module" and the module entry accordingly.
• Smart scripts – Empty script fields are dropped instead of left as "" placeholders.
• Dependency parsing – Paste a list of package@^1.2.3 entries and they become a tidy dependencies object.
• Repository helpers – Drop in a GitHub URL and the generator fills repository, bugs, and homepage for you.
• Private flag – One click marks the package as private to prevent an accidental npm publish.
• Indent your way – Output as 2 spaces, 4 spaces, or tab to match your repo’s existing style.
• Copy or download – Grab the result as text or download package.json directly.
