Nodejs Hapi - How to enable cross origin access control

Where did you put cors=true? Could you add some code?

Without know exactly where you've put cors = true, this bit of code may help you:

server.connection({ routes: { cors: true } })

Or try adding the allowed cors in the config section of your route.

server.route({
    config: {
        cors: {
            origin: ['*'],
            additionalHeaders: ['cache-control', 'x-requested-with']
        }
    },

Take a look at this question: hapi.js Cors Pre-flight not returning Access-Control-Allow-Origin header

Addition to @James111's answer,

Even if that answer doesn't work for you. check for additional Auth headers that you are sending.

In my case it was X_AUTH_TOKEN, so in additionalHeaders you might want to add your custom header as well.

e.g.

additionalHeaders: ['cache-control', 'x-requested-with', 'X_AUTH_TOKEN']
