The recommended way to set the locale for a Ext JS 7.4.0 modern app is in app.json:
"requires": [
"ext-locale"
],
"locale": "de",
This works fine for sencha app build development but has no effect for sencha app build production (the production build just uses the default english locale).
I also tried by setting the build descriptor in app.json:
"builds": {
"modern": {
"toolkit": "modern",
"locales": [
"de"
]
}
},
Sencha Cmd then processes the modern-de instead of the default build descriptor, but still, no effect in the production build.
