Installation

Install the package using npm:

Setup

1. Import and Use in Express

const express = require("express");
const mongoose = require("mongoose");
const { generateCrudRoutes } = require("mongoose-crud-generator");
const User = require("./models/User"); // Example Mongoose model

const app = express();
app.use(express.json());

// Define API options
const options = {
  authOptions: { authenticate: true, authMiddleware: require("./middlewares/auth") },
  preHooksOptions: { pre: { getAll: async (req, res) => console.log("Pre Hook Triggered") } },
  postHooksOptions: { post: { getAll: async (req, res, response) => response } },
  middlewareOptions: { customMiddleware: require("./middlewares/customMiddleware") },
  encryption: { enable: true, secretKey: "your-secret-key" },
};

// Generate routes
const userRoutes = generateCrudRoutes({ model: User, modelName: "User", options });
app.use("/users", userRoutes);

// Start server
app.listen(3000, () => console.log("Server running on port 3000"));

Customize API logic using pre and post hooks:

};
