SyntaxError: Cannot use import statement outside a module Firebase Functions

Question

I'm, having an issue with my Firebase function. I'm getting the below error.

SyntaxError: Cannot use import statement outside a module

below is my code:

import * as functions from 'firebase-functions';
import * as sgMail from '@sendgrid/mail';

sgMail.setApiKey(key);

export const weeklyReminder = functions.pubsub.schedule('every Wednesday 21:00').onRun(async context =>{

    const msg = {
        to: 'email@gmail.com',
        ...
    };
    return sgMail.send(msg);

});

How do you import into firebase functions?

Are you using TypeScript or vanilla JavaScript? With plain JavaScript you'd use require like this:

const functions = require('firebase-functions');

Also, change the function to be the same as the below:

exports.weeklyReminder = functions.pubsub.schedule('every Thursday 21:00').onRun(

If you import it that way can you still use ”export const weeklyReminder” if not not do you export the function – Chris Evans Jan 16 '20 at 07:00

Also using vanilla JavaScript – Chris Evans Jan 16 '20 at 07:03

No you'd use: exports.weeklyReminder = functions.pubsub.schedule('every Wednesday 21:00').onRun(async context =>{ – Jason Byrne Jan 16 '20 at 17:22
@JasonByrne VS Code suggest to use ES module thus ended up with `import { region } from 'firebase-functions';`. Should we just ignore the suggestion? – Bitwise DEVS Jul 29 '22 at 20:48

For me, I needed curly brackets around my instance, like so:

const { functions } = require('firebase-functions');

Otherwise I would get

TypeError: functions is not a function
