Express.js middleware for validating content type

Express.js middleware for validating content type. Very simple but often sorely needed. Sends response with status code 415 (Unsupported Media Type) if content type doesn't match. Use Express's req.is behind the scenes.

Usage

ES modules

import validateContentType from '@natlibfi/express-validate-content-type';
app.post('/', validateContentType({type: 'application/json'}), (req, res) => {...});

Node.js require

const {default: validateContentType} = require('@natlibfi/express-validate-content-type');
app.post('/', validateContentType({type: 'application/json'}), (req, res) => {...});
