      • format

        @Stability(Experimental)
        public AddBundleOptions.Builder format​(String format)
        Parameters:
        format - Output format for the generated JavaScript files. There are currently three possible values that can be configured: "iife", "cjs", and "esm".

        If not set (undefined), esbuild picks an output format for you based on platform:

        • "cjs" if platform is "node"
        • "iife" if platform is "browser"
        • "esm" if platform is "neutral"

        Note: If making a bundle to run under node with ESM, set format to "esm" instead of setting platform to "neutral".

        Returns:
        this
      • loaders

        @Stability(Experimental)
        public AddBundleOptions.Builder loaders​(Map<String,​String> loaders)
        Parameters:
        loaders - Map of file extensions (without dot) and loaders to use for this file type. Loaders are appended to the esbuild command by --loader:.extension=loader
        Returns:
        this
      • externals

        @Stability(Experimental)
        public AddBundleOptions.Builder externals​(List<String> externals)
        Parameters:
        externals - You can mark a file or a package as external to exclude it from your build. Instead of being bundled, the import will be preserved (using require for the iife and cjs formats and using import for the esm format) and will be evaluated at run time instead.

        This has several uses. First of all, it can be used to trim unnecessary code from your bundle for a code path that you know will never be executed. For example, a package may contain code that only runs in node but you will only be using that package in the browser. It can also be used to import code in node at run time from a package that cannot be bundled. For example, the fsevents package contains a native extension, which esbuild doesn't support.

        Returns:
        this
      • watchTask

        @Stability(Experimental)
        public AddBundleOptions.Builder watchTask​(Boolean watchTask)
        Parameters:
        watchTask - In addition to the bundle:xyz task, creates bundle:xyz:watch task which will invoke the same esbuild command with the --watch flag. This can be used to continusouly watch for changes.
        Returns:
        this
