Ensure Content-Type
Tiny express middleware for blocking unwanted Content-Type(s). When a type doesn't match, a 400 error is sent to the client, otherwise the next middleware is called.
Usage:
const express = require('express');
const ensureCtype = require('express-ensure-ctype');
const ensureJson = ensureCtype('json');
const app = express();
app.post('/', ensureJson, (req, res) => {
res.json(req.body);
});
app.listen(3000);
Result:
curl -i -XPOST http://localhost:3000/
