Typescript Single Module Bundles

TsBundler supports a "bundles" property within the Typescript project configuration json file. The "bundles" property may contain a list of named bundles. Each bundle must provide an array of source files and may optionally specify bundle configuration settings. The Typescript source file and its dependencies are packaged as a single Typescript file and output with the bundle name. The Typescript bundle is compiled to a single js javascript file and a single d.ts declaration file.

The following is a sample tsconfig.json showing the "bundles" property:

    "compilerOptions": {
        "module": "amd",
        "target": "es5",
        "noResolve": false,
        "declaration": true,
        "diagnostics": true

    "files": [
    "bundles": {
        "app": {
            "files": [ "index.ts" ]
        "components": {
            "files": [
            "config": {
                "declaration": true,
                "outDir": "./bundles",
                "minify": true  

Node API

    interface BundlerOptions {
        verbose?: boolean;
        logLevel?: number;
        outputToDisk?: string;
    interface BuildResult {
        errors: ts.Diagnostic[];
        bundleOutput?: ts2js.CompilerResult[];
        succeeded(): boolean;

    interface BundleBuilder {
        build( buildCompleted: (result: BuildResult) => void): void;
        src(): stream.Readable;
    function builder(configFilePath: string, bundlerOptions?: BundlerOptions, buildCompleted?: (result: BuildResult) => void): BundleBuilder;

How to install
