Introduction

handdeng-node-server is a lightweight HTTP server framework built on Node.js, designed to simplify the creation and management of API services. This framework provides flexible routing, permission verification, parameter validation, and error handling mechanisms, making it ideal for building high-performance RESTful API services.

Features

• GET/POST Routing: Supports the registration of handler functions for GET and POST requests.
• Permission Verification: Allows enabling or disabling permission checks for individual APIs.
• Parameter Validation: Supports type and required field validation for API request parameters.
• Global Error Handling: Provides customizable global error handling mechanisms.
• Flexible Routing: Supports custom handling for missing routes and incorrect HTTP methods.

Quick Start

1. Install Dependencies

   npm install handdeng-node-server

2. Create a Server Instance

   import { NodeServer } from "handdeng-node-server";
   const server = new NodeServer(3000, "localhost");

3. Register API Routes

   server.get("/api/test", (req, res) => {
     res.writeHead(200, { "Content-Type": "application/json" });
     res.end(JSON.stringify({ message: "GET request success" }));
   });
   
   server.post("/api/test", (req, res) => {
     res.writeHead(200, { "Content-Type": "application/json" });
     res.end(JSON.stringify({ message: "POST request success" }));
   });

4. Start the Server

   Run your script to start the server:

   node index.js

5. Test the API

   You can test your API by visiting http://localhost:3000/api/test.

API Configuration Options

• openPermissionVerify: Whether to enable permission verification. Default is true.
• paramsList: A list of parameter validation rules, including the parameter key, type, and whether it's required.
