mongoose-init

Instantly generate a Mongoose connection boilerplate in any JavaScript/TypeScript project with a single command.

Usage

npx mongoose-init

This will create a lib/db.ts file in your project with a ready-to-use Mongoose connection.

Generated file

import mongoose from "mongoose";

const MONGODB_URI = process.env.MONGODB_URI || "";

if (!MONGODB_URI) {
  throw new Error("Please define MONGODB_URI in your .env file");
}

export async function connectDB() {
  try {
    if (mongoose.connection.readyState >= 1) return;
    await mongoose.connect(MONGODB_URI);
    console.log("MongoDB connected successfully");
  } catch (error) {
    console.error("MongoDB connection failed:", error);
    process.exit(1);
  }
}

Setup

After running the command, add your MongoDB URI to your .env file:

MONGODB_URI=your_mongodb_connection_string

Then import and use it anywhere in your project:

import { connectDB } from "./lib/db";

await connectDB();

Works with

• Next.js
• Express
• Plain Node.js
• Any JavaScript/TypeScript project
