Learning TypeScript 2.x - Second Edition

Compiling internal modules

Once we have finished declaring our internal modules, we can decide whether we want to compile each one into JavaScript or whether we prefer to concatenate all the files into one single file.

We can use the --out flag to compile all the input files into a single JavaScript output file:

tsc --out output.js input.ts 

The compiler will automatically order the output file based on the reference tags present in the files. We can then import our files or file using an HTML <script> tag.
