How do I get TypeScript to bundle a 3rd party lib from node_modules?

Question

I would like the TypeScript Compiler to use node_modules/firebase/firebase.d.ts to typecheck my code and also bundle node_modules/firebase/firebase.js

Answer 1

tsc is a compiler, not a bundler. This question expounds on bundling a bit.

While developing in TypeScript, gulp + gulp-browserify can provide a watcher and bundler.

With "module": "umd" in the compiler options, this gulpfile.js will do the rest:

var gulp = require('gulp');
var ts = require('gulp-typescript');
var browserify = require('gulp-browserify');

gulp.task('default', function () {
  return gulp.src('src/*.ts')
    .pipe(ts.createProject('tsconfig.json')())
    .pipe(browserify())
    .pipe(gulp.dest('dist/gen'));
});

gulp.task('watch', ['default'], function () {
  gulp.watch('src/*.ts', ['default']);
});
