How to use await async in firebase cloud function?

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 getUserFunction (/var/tmp/worker/worker.js:413:24)

!  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.

node.green ... you have to upgrade. Simply npm a upgrade to node or install it directly (windows)

Please edit the question to show the version of the CLI you're using, and proof that your function deployed to node 8 (it will be in the output). Also you should know that TypeScript is a strict superset of JavaScript, so all your JavaScript will just keep working if you just copy it over to TS.

I am not with my laptop rn but I have ensured that all my tools and framework are up-to-date. If you think I should shift to typescript, please do tell me how to migrate my project to ts.

You also need to be using Node.js 8 on your local machine, or the CLI will have parse errors when trying to extract trigger information from your code.

Can you make sure adding "engines": {"node": "8"} into functions/package.json, not package.json?

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.
