_x000D_ If you use Express (high-performance, high-class web development for Node.js), you can do this: HTML:

API client: fetch('/', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ user: { name: "John", email: "john@example.com" } }) }); Node.js: (since Express v4.16.0) // Parse URL-encoded bodies (as sent by HTML forms) app.use(express.urlencoded()); // Parse JSON bodies (as sent by API clients) app.use(express.json()); // Access the parse results as request.body app.post('/', function(request, response){ console.log(request.body.user.name); console.log(request.body.user.email); }); Node.js: (for Express <4.16.0) const bodyParser = require("body-parser"); /** bodyParser.urlencoded(options) * Parses the text as URL encoded data (which is how browsers tend to send form data from regular forms set to POST) * and exposes the resulting object (containing the keys and values) on req.body */ app.use(bodyParser.urlencoded({ extended: true })); /**bodyParser.json(options) * Parses the text as JSON and exposes the resulting object on req.body. */ app.use(bodyParser.json()); app.post("/", function (req, res) { console.log(req.body.user.name) });
