By default POST requests through json-server should give a 201 created response.
If you need custom response handling, you might need a middleware to get hold of req and res object.
Here I'm adding a middleware to intercept POST requests and send a custom response. You could tweak it to your specific case.
// Custom middleware to access POST methods.
// Can be customized for other HTTP method as well.
server.use((req, res, next) => {
console.log("POST request listener");
const body = req.body;
console.log(body);
if (req.method === "POST") {
// If the method is a POST echo back the name from request body
res.json({ message:"User created successfully", name: req.body.name});
}else{
//Not a post request. Let db.json handle it
next();
}
});
Complete code (index.js)..
const jsonServer = require("json-server");
const server = jsonServer.create();
const router = jsonServer.router("db.json");
const middlewares = jsonServer.defaults();
server.use(jsonServer.bodyParser);
server.use(middlewares);
// Custom middleware to access POST methids.
// Can be customized for other HTTP method as well.
server.use((req, res, next) => {
console.log("POST request listener");
const body = req.body;
console.log(body);
if (req.method === "POST") {
// If the method is a POST echo back the name from request body
res.json({ message:"User created successfully", name: req.body.name});
}else{
//Not a post request. Let db.json handle it
next();
}
});
server.use(router);
server.listen(3000, () => {
console.log("JSON Server is running");
});
And you can start json-server using node index.js
