great,... thank you for answer, i use this code in server.js and work to POST, PUT and DELETE in herokuapp . .

var jsonServer = require('json-server');
var server = jsonServer.create();
var router = jsonServer.router('db.json');
var middlewares = jsonServer.defaults();
var port = Number(process.env.PORT || 3000);
server.use(middlewares);
server.use(router);
server.listen(port, function () {
  console.log('JSON Server is running')
});

Heroku doesn't allow to write to a file. You need to enable an addon.

But currently json-server doesn't support other storages than files.

Alternatively, you could deploy to a VPS or another PAAS that would support file writing. I don't know if it's possible with now.sh but it's worth a try.

On Heroku, you could also use json-server with in-memory storage:

var jsonServer = require('json-server')
var server = jsonServer.create()
var db = {
  posts: [],
  comments: []
}
var router = jsonServer.router(db)
var middlewares = jsonServer.defaults()

server.use(middlewares)
server.use(router)
server.listen(3000, function () {
  console.log('JSON Server is running')
})

POST would be possible, but that would mean that data would be lost every time the dyno is restarted (not a problem if it's just for mocking).

It would be possible to add support for other storages but it would require some development.
