Express wildcard origin snippet

Posted on July 23, 2020

Here for future reference, assuming a typical express app, the middleware to accept any origin for every requests:


app.use(cors())

app.use(function (req, res, next) {
  res.header('Access-Control-Allow-Origin', '*')
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept')
  next()
})

You need to install cors, though.
