I've built a couple of cloud functions in nodejs 6 and now i want to use await. How do I do that? How can I upgrade to node 8? I don't want to shift to typescript.

I've tried adding "engines": {"node": "8"} to package.json but it changed nothing.

This is a test cloud function I made:

exports.awaittest = functions.https.onRequest(async (req, res)=>{

    ref = await admin.database().ref("/something/");

    res.send(ref)

})

when I try to deploy it (with package.json edited), I get this:

SyntaxError: Unexpected token (

    at createScript (vm.js:56:10)

!  functions[awaittest]: Deployment error.

Function load error: Code in file index.js can't be loaded.

Is there a syntax error in your code?

                                                    ^

How do I upgrade to node8? I already have 6 functions deployed in node6.

Okay I solved it. I had to first remove my older cloud functions via Google Cloud console, updated firebase-tools and then re-deployed everything with "engines": {"node": "8"} added to functions/package.json.
