gulp-typescript-helper

Provides a single simplified means for building TypeScript with:

• Source Maps
• Declaration Files
• Minification

Other features:

• Resolves using promises instead of streams for more easy of use and flexibility.
• Use whatever Promise library you want.

Usage:

Write your tasks like this:

    import {Target, Module, CoreTypeScriptOptions, BuildHelper} from "gulp-typescript-helper";
        
    const DEFAULTS:CoreTypeScriptOptions = {
        noImplicitAny: true,
        removeComments: true,
        noEmitHelpers: true,
        sourceMap: true,
        declaration: true
    });
    
    
    const builder = BuildHelper
        // Setup the builder by injecting a promise constructor.
        .inject(PromiseFactory) // Optional: will use Q as a default.
        // Define your source folder and destination base path.
        .fromTo(PATH.SOURCE, "./dist" , DEFAULTS);
    
    // Subsequent tasks are simplified down to this:
    gulp.task(
        TASK.DIST_UMD,
        ()=> builder
            .init(
                MODULE.UMD + '.min',
                TARGET.ES5,
                MODULE.UMD)
            .clear() // Clears the destination directory.
            .minify() // Signals to enable minification (uglify).
            .execute() // Commences the build pipeline
            .then(()=>
                /* Whatever steps you want to do before completion */) //
    );
