req-trapper

req-trapper is an Express middleware for request validation inspired by Laravel request validation. It allows you to define validation rules for your API requests and ensures that incoming data in the request payload meets your specified criteria.

Features

• Simple and Expressive: Define validation rules for your request data with a clean and expressive syntax.

• Middleware Integration: Easily integrate req-trapper into your Express application as middleware for route-specific request validation.

• Extensible: Customize validation rules to suit your application's specific needs(This is in progress)

Installation

Install req-trapper using npm:

npm install req-trapper

Usage

Basic Example

import ReqTrapper from 'req-trapper';
import express from 'express';

const app = express();
const reqTrapper = new ReqTrapper();



// Use req-trapper as middleware
app.post('/example',
    reqTrapper.validate([{ name: 'phone', validation: 'required|number' }]), // validation rules
    (req, res) => {
  // Your route logic here
});

// works across multiple requests
app.post('/example2',
    reqTrapper.validate([{ name: 'email', validation: 'required|email' }]), // validation rules
    (req, res) => {
        // Your route logic here
