Async/await im Plugin: funktioniert in der Dev-Instanz, nicht in der Docker-Instanz

I get this error when installing a plugin in a docker instance:

Removing async/await fixes the issue. It looks like some es6 code is sent to uglifyjs before conversion to es5.

The error doesn’t always occur. A few days ago, I retried installing several times and it finally succeeded. But now I’m stuck again.

Did you name your plugin file name.js.es6 ?

3

Nope, none of my plugin files are named name.js.es6.

4

Hence the problem, you need to name them with that extension.

5

My plugin has just installed correctly, at the 3rd attempt.

6

If you want it to compile properly, make sure they have a .js.es6 extension, then it will work everytime.

7

I am not even sure if we enabled async await in babel @eviltrout ? I certainly have never used it in the Discourse code base.

8

@Falco, if your question was about the extension of my files, then yes, I’m using .js.es6 everywhere.

9

We are not transpiling that. It probably works in the browser if you’re using an evergreen one, but we don’t support it yet.

We could benefit from it, I just haven’t had the time to enable it, make sure the perf is good, and start converting code.

10

Any news on this? Having it would be great.

11

We did start using this in tests, have not decided on our strategy yet for using it in production or not.

12

Haben Sie hier schon Fortschritte gemacht?

13

@eviltrout hat eine lange Spike-Arbeit begonnen, um uns auf die Nutzung von Ember CLI vorzubereiten. Ein Teil der Arbeit sollte dies als Nebeneffekt klären.

Ich erwarte, dass wir dies innerhalb der nächsten 8 Monate gelöst haben.

14

Ich habe dieses Problem auch.

Ich verwende name.js.es6 überall.

Bedeutet das, dass ich async/await entfernen muss?

15

Ja, wir unterstützen async/await noch nicht, wie erklärt.
