Import default issue with babel@6 about firebase-functions

[mbleigh]

You can just do import * as functions from 'firebase-functions' The lack of a default export is intentional and necessary for compatibility.

Here's how to reproduce: import functions from 'firebase-functions' export const helloWorld = functions.https.onRequest((request, response) => { response.send('Hello World!') }) which is transpiled into (using ***@***.*** es2015 preset): 'use strict'; Object.defineProperty(exports, "__esModule", { value: true });exports.helloWorld = undefined; var _firebaseFunctions = require('firebase-functions'); var _firebaseFunctions2 = _interopRequireDefault(_firebaseFunctions); function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; } var helloWorld = exports.helloWorld = _firebaseFunctions2.default.https.onRequest(function (request, response) { response.send('Hello World!'); }); which produces the following error when deploying: i deploying functions i functions: ensuring necessary APIs are enabled... i runtimeconfig: ensuring necessary APIs are enabled... ✔ runtimeconfig: all necessary APIs are enabled ✔ functions: all necessary APIs are enabled i functions: preparing functions directory for uploading...

This could be related to babel's T2212 Kill CommonJS default export behaviour <babel/babel#2212>. A quick workaround is to import the individual package instead of importing the default: import { https } from 'firebase-functions' export const helloWorld = https.onRequest((request, response) => { response.send('Hello World!') }) which transpiles into: 'use strict'; Object.defineProperty(exports, "__esModule", { value: true });exports.helloWorld = undefined; var _firebaseFunctions = require('firebase-functions'); var helloWorld = exports.helloWorld = _firebaseFunctions.https.onRequest(function (request, response) { response.send('Hello World!'); }); which has no issue to run and to deploy. The fix should be a relatively easy one which is to explicitly export a default in firebase-functions. — You are receiving this because you are subscribed to this thread.

Hi @achuthhadnoor, which version of node are you using? Can you paste here the result of running node --version?

[achuthhadnoor]

Hi @justinrosenthal the node version I use is v4.4.5

[justinrosenthal]

@achuthhadnoor That's likely why you're having problems. You should upgrade (or install via nvm) to Node v6.11.1 as mentioned in the Getting Started guide.

v6 supports many more language features than v4, you can find more information here: http://node.green/
