An experimental browser application builder (`browser-esbuild`) has been introduced that leverages esbuild as the bundler. This new builder is compatible with options of the current browser application builder (`browser`) and can be enabled for experimentation purposes by replacing the `builder` field of `@angular-devkit/build-angular:browser` from an existing project to `@angular-devkit/build-angular:browser-esbuild`. The builder will generate an ESM-based application and provides support for ES2015+ compatible output with ES2020 as the default. This builder is considered experimental and is not recommended for production applications. Currently not all `browser` builder options and capabilities are supported with this experimental builder. Additional support for these options may be added in the future. The following options and capabilities are not currently supported: * Stylesheet Preprocessors (only CSS styles are supported) * Angular JIT mode (only AOT is supported) * Localization [`localize`] * Watch and dev-server modes [`watch`, `poll`, etc.] * File replacements [`fileReplacements`] * License text extraction [`extractLicenses`] * Bundle budgets [`budgets`] * Global scripts [`scripts`] * Build stats JSON output [`statsJson`] * Deploy URL [`deployURL`] * CommonJS module warnings (no warnings will be generated for CommonJS package usage) * Web Workers * Service workers [`serviceWorker`, `ngswConfigPath`]
