How to combine TypeScript code and JS libraries into one file with source maps?

Typescript compiler isn't so smart, to do this you need use more specific tools. Example: gulpjs.

Requirements (if you know gulpjs skip this):

1. install nodejs
2. run this: npm install -g typescript gulp to install gulp taskrunner
3. in project directory, run npm init and follow instruction to create package.json
4. run: npm install gulp gulp-typescript gulp-concat gulp-uglify gulp-sourcemaps --save-dev to install ts compile, concat, uglify e generate sourcemaps tools
5. create file with name gulpfile.js

Define 'compile' task in gulpfile.js :

var gulp = require('gulp');var ts = require('gulp-typescript');var concat = require('gulp-concat');var sourcemaps = require('gulp-sourcemaps');var uglify = require('gulp-uglify');gulp.task('compile', function() {     var tsResult = gulp.src('app.ts')        .pipe(sourcemaps.init()) // This means sourcemaps will be generated         .pipe(ts({             sortOutput: true,                       // ...          }));      return tsResult         .pipe(concat('lib/js-library.js')) // You can use other plugins that also support gulp-sourcemaps         .pipe(uglify())          .pipe(sourcemaps.write()) // Now the sourcemaps are added to the .js file          .pipe(gulp.dest('release/'));});

And now, run gulp compile and see the magic!
