This is easy to use simple validator middleware for express routes. No need to validate input parameters manually, just configure route middleware. Uses Joi library: https://github.com/hapijs/joi

Install with npm

  npm install express-joi-params

Use

In your express route file include

const validation = require('express-joi-params');
const rule = require('express-joi-params').rule;

or

import validation, { rule } from 'express-joi-params';

then in any rote add middleware

router.post('/api/login', validation.validateRequest({
  body: {
    login: rule.string().required(),
    password: rule.string().required(),
  },
}), authController.login);

    "success": false,
    "errors": {
        "errors": [
            {
                "message": "\"login\" is required",
                "type": "any.required",
                "field": [
                    "login"
                ]
            }
        ],
