Can sencha app watch command produce ES5 code if we have javascript code in ES6

[praveensaini23]

Hi All,

In my ExtJS 6.5 application, code is written in ES6 syntax. When I am creating a testing build, app.js file is also have the code in ES6. I have fixed that problem by putting below line under output config in app.json file -

"js": {
"path": "app.js",
"version": "ES5"
}


Above is working fine when we are running command - sencha app build testing.
The problem is I need that ES5 code without running build command, it should be happening automatically from running sencha app watch command.

Means I will run sencha app watch in console, and try to make any change in file, cmd is compiling scss file and creating css file, so I need same thing, when I will make any change in JS code and write any ES6 syntax, sencha app watch should catch the changes immidiately and should rewrite the app.js file in ES5 syntax.

Waiting for the answer, thanks.

I'm so bummed to see that this question went unanswered. I'm running into the same issue because our team has to build IE-compliant apps, and it's very frustrating that we cant use most ES6+ features and still get HMR/Watch capability (since we need to test in IE).

@praveensaini23 - did you find an answer to this?

I am still doing the same way that I mentioned above like, give above config in app.json and then create build via sencha app build testing command. Then test that build in IE.
Note that the testing build will have IE understandable syntax.

But no solution yet with sencha watch.
