How to set up gulp-typescript to generate one javascript file per typescript file into the same directory?

Question

I would like to use gulp-typescript module to take care typescript compiling. The current setup I would like to achieve is having one javascript file per typescript file in the same directory. It is the same what VS Typescript module does.

Unfortunately, I did not find anything like this in the documentation. I also searched for this in the google but there is no result.

Thanks for any help in advance!

The following will look for each .ts file in src directory and compile it in the same path as the source

gulp.task('scripts' , function(){
    return gulp.src('src/**/*.ts')
    .pipe(
        ts({
             "compilerOptions": {
                 "target": "es5",
                 "module": "commonjs",
                 "sourceMap": true
             }
        })
    )
    .pipe(gulp.dest(function(file) {
    return file.base;
  }));
});

Below is sample gulp task that will compile your program in accordance with tsconfig and put js files in the same folder as ts ones:

gulp.task('build', 
function() 
{
    var tsProject = ts.createProject('tsconfig.json');

    var tsResult = tsProject.src()
        .pipe(ts(tsProject));

    return tsResult.js.pipe(gulp.dest("./"));
});

var ts = require('gulp-typescript'); – Agriculture
