depify

Auto scan JavaScript / TypeScript imports and install missing dependencies automatically.

🚀 What is depify?

depify is a CLI tool that scans your project source code, detects external imports, resolves them to root npm packages, and installs them in one step.

It is designed for projects that are:

• newly cloned
• empty node_modules
• missing setup dependencies
• or need quick bootstrap from source code

⚙️ How it works

source code
   ↓
scan imports (js / ts / jsx / tsx)
   ↓
filter local + built-in modules
   ↓
resolve import → root package
   ↓
deduplicate
   ↓
npm install

📦 Features

• Scan .js, .jsx, .ts, .tsx, .mjs, .cjs
• Detect import, require, and dynamic imports
• Ignore local paths (./, ../, @/, ~/)
• Ignore Node.js built-in modules
• Resolve sub-path imports to root package (e.g. next/image → next)
• Deduplicate dependencies before install
• Simple CLI usage

🧑‍💻 Installation

npm install -g depify

or

npm link

▶️ Usage

Run inside your project:

depify

It will:

1. Scan all source files
2. Detect dependencies
3. Install missing packages

🧪 Example

Input code:

import React from "react";
import Image from "next/image";
import { useQuery } from "@tanstack/react-query";

Output:

installing: react, next, @tanstack/react-query

⚠️ Notes

• This tool does not replace package.json
• It does not manage versions
• It is intended for bootstrap / setup purposes only
• Dev dependencies may also be detected depending on project structure

🧠 Limitations

• Uses static scanning (not full AST parsing yet)
• May include false positives in complex monorepos
• Does not distinguish devDependencies vs dependencies automatically
• Does not resolve TypeScript path aliases (tsconfig paths) yet

🔮 Future improvements

• AST-based parsing for higher accuracy
• Detect dev vs production dependencies
• Support monorepo & workspace
• Read tsconfig.json aliases
• Dry-run mode (--dry-run)
• Smart install grouping
