xss-shield

This package provides a middleware for Express.js that helps protect against cross-site scripting (XSS) attacks. It's built on top of the xss module and is written in TypeScript.

Installation

To use this middleware, first install it using npm or yarn:

npm install xss-shield

or

yarn add xss-shield

Usage

To use this middleware in your Express.js application, simply require or import it and add it to your middleware stack:

const express = require('express'); 
const xssShield = require('xss-shield');

const app = express();

// Add the middleware to the middleware stack
app.use(xssShield());

You can also pass options to the middleware to customize its behavior. See the xss documentation for available options.

const express = require('express'); 
const xssShield = require('xss-shield');

const app = express();

// Add the middleware to the middleware stack with options
app.use(xssShield({
  whiteList: {
    a: ['href', 'title', 'target'],
    img: ['src', 'alt'],
  }
}));
