Your gulpfile.esm.js:

import tts from 'ttypescript';
import typescript from 'gulp-typescript';
import {
    src,
    dest,
    task,
    parallel,
} from 'gulp';

task('deploy.dev',
    () => {
        // Transpiling for browser tsconfig
        const tsApp = typescript.createProject(
            './src/tsconfig.dev.json',
            { typescript: tts },
        );

        const tsResult = tsApp.src()
            .pipe(tsApp()).js;

        return tsResult
            .pipe(uglifyES())
            .pipe(dest(
                // deploy dev files
                tsApp.config.compilerOptions.outDir,
            ));
    });

Tested same tsconfig with npm script ttsc --project ./tsconfig.json it's ok, but gulp-typescript configuration is not.

Sorry, you were having a different issue as what I thought. Can you share a TypeScript file on which you see this error? That would make it easier for me to debug this.

@ivogabe : Sorry, i'm checking your library on small project & everything is working, thanks!

[ivogabe]

Great, that's good news :)
