Does Electron v4 support ECMAScript modules?

问题

I am writing apps using Electron. The current version, 4.0.6, is based on Node 10.11.0 and Chrome 69.0.3947.106.

I thought the latest version of Electron would support ECMAScript (ES6) modules but I have not been able to make them work, so far. In particular, on starting the app, the line:

import { runTask } from './action';

gives the run-time error:

Uncaught SyntaxError: Unexpected token {

Before I put more effort into tracking down the problems, I would like to know the status of module support in Electron.

Does Electron version 4 (Chrome 69) support ECMAScript (ES6) modules?

回答1:

Chrome has apparently supported them Chrome 63:

https://caniuse.com/#feat=es6-module-dynamic-import

That might mean you can use them in your front-end?

But node v11.11.0 appears to only support them with an extra flag, --experimental-modules:

https://nodejs.org/api/esm.html

I cannot find a reference, but maybe node 10.11.0 is the same, and that will make them work on the Electron back-end too?

(Sorry, I'm still on an older Electron, and happily using old-fashioned require(), so cannot tell you from personal experience if it will work.)

回答2:

Surely you are missing the type="module" attribute on your <script> tag.

Then you will hit the file protocol issue, which you can work around by registering your own protocol, as described in Electron ES6 module import
