Description

Since angular 2 came out there have been ongoing discussions about the best way to load locales if you don't know the locale ahead of time. For example, my company supports over 200 locales so importing each one at the top of the file is not realistic. The most recent accepted workaround was to do the below. Now with esbuild this no longer works. Is there an accepted way to do this now?

          /* webpackMode: "lazy-once" */
          /* webpackChunkName: "i18n-base" */
          /* webpackExclude: /(^en)\.js/ */
          /* webpackExclude: /\.d\.ts$/ */
          `@/../node_modules/@angular/common/locales/${localeId}.mjs`
        ).then(
          module => {
            registerLocaleData(module.default, localeId);
            resolve();
          },
          () => {
            import(
              /* webpackMode: "lazy-once" */
              /* webpackChunkName: "i18n-base" */
              /* webpackExclude: /(^en)\.js/ */
              /* webpackExclude: /\.d\.ts$/ */
              `@/../node_modules/@angular/common/locales/${localeId.split('-')[0]}.mjs`
            )
              .then(module => {
                registerLocaleData(module.default, localeId);
                resolve();
              })
              .catch((e) => {
                console.error(e);
                //Need to fall back to something
                return this.handleEnglishLocale(localeId, resolve, reject);
              });

Minimal Reproduction

ng build after having a service that tries to load locale dynamically.
