Route validation for Express using Joi

codecov

This custom middleware is for those who prefer to use Express but want to use the Joi validation library to validate the query, params, and body of requests.

Usage

Without route validation, an endpoint may look something like this:

app.get('/contacts/:id', contactsHandler);

To implement route validation, simply call the provided validation function with the desired schema that uses Joi:

const Joi = require('@hapi/joi');
const validate = require('express-joi-validate');
 
const contactSchema = {
  params: {
    id: Joi.number().required()
  }
};
 
app.get('/contacts/:id', validate(contactSchema), contactsHandler);

For detailed usage and more examples, see the blog post Express route param validation (Node.js).
