no cors config not working with json-server

I'm using json-server to create a mock API of my actual API for offline testing purpose. I can see the mock API response under their Url endpoint: localhost:5001/api/searchresults/*

but on my app I cannot see the results because the request is blocked by CORS. Reading the json-server docu, there is a way to disable CORS issues, adding jsonServer.defaults({ noCors: true }) as middleware.

I than add a custom server and run this with node server.js

// server.js
const jsonServer = require('json-server')
const server = jsonServer.create()
const router = jsonServer.router('db.json')
const middlewares = jsonServer.defaults({ noCors: true })

server.use(middlewares)

server.use('/api/searchresults', router)
server.listen(5001, () => {
  console.log('Mock api server listening at localhost:5001')
})

but unfortunately I still get cors issues when try to fetch my data.

Anyone has an idea why is not working or how to address this problem?

Solution

Since it seems that the json-server package is not mantained anymore https://github.com/typicode/json-server/issues/1219 I figured out a way to fix it with just Express

server.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin', 'http://localhost:3000')
  res.header('Access-Control-Allow-Headers', '*')
  next()
})

Adding those lines worked for us I hope can be helpful for someone else in similar situation
