CORS express not working predictably

Question

I am trying to allow access from everywhere.

I have tried using app middleware:

app.use(function (req, res, next) {
  res.setHeader(\"Access-Control-Allo         


        

Answer 1

Following other's answers, this worked for me:

res.setHeader("Access-Control-Allow-Origin", 'http://myDomain:8080');
res.setHeader('Access-Control-Allow-Methods', 'POST,GET,OPTIONS,PUT,DELETE');
res.setHeader('Access-Control-Allow-Headers', 'Content-Type,Accept');
