I am currently developing an application that needs to support multiple languages, specifically up to 20 different languages.
The default language set for the application is en-US. The translated versions are generated successfully during the build process.
However, regardless of the build configuration, the LOCALE_ID remains static as en-US. This inconsistency causes issues with using locale in pipes and other aspects of the application. The value does not reflect the locale specified in the build settings.
Upon compilation, a warning message similar to this one for German appears for each locale:
Locale data for 'de-DE' cannot be found. No locale data will be included for this locale.
This snippet showcases how the build configuration is defined in angular.json:
"production-de": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
],
"optimization": true,
"outputHashing": "all",
"sourceMap": false,
"extractCss": true,
"namedChunks": false,
"aot": true,
"extractLicenses": true,
"vendorChunk": false,
"buildOptimizer": true,
"budgets": [
{
"type": "initial",
"maximumWarning": "2mb",
"maximumError": "5mb"
},
{
"type": "anyComponentStyle",
"maximumWarning": "6kb"
}
],
"outputPath": "dist/de",
"baseHref": "/de/",
"i18nLocale": "de-DE",
"i18nFile": "src/locale/messages/messages.de.xlf",
"i18nFormat": "xlf"
},
The command used to build the application is:
ng build configuration=production-de
Here's a glimpse into my app.module.ts file:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule, LOCALE_ID } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { registerLocaleData } from '@angular/common';
import localeEn from '@angular/common/locales/en';
import localeEnExtra from '@angular/common/locales/extra/en';
registerLocaleData(localeEn, 'en-US', localeEnExtra);
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
AppRoutingModule,
HttpClientModule
],
providers: [
{
provide: LOCALE_ID,
useValue: 'en-US'
}
],
bootstrap: [
AppComponent
]
})
export class AppModule { }
It seems that even after building, the registerLocaleData function and the provider for LOCALE_ID remain unchanged.
I attempted to remove registerLocaleData and the LOCALE_ID provider since en-US is already the default setting in Angular. However, this did not rectify the issue.
Would it be necessary to adjust the app.module.ts file with specific values for registerLocaleData? Implementing this change for all 20 languages seems impractical.
Alternatively, is there a correct method to deploy the application effectively in multiple languages without encountering these limitations?
Could there be a crucial configuration step that I am overlooking?
