 Upon successful compilation, you should see a `dist` directory in your project root containing the compiled files, with the entry point being `main.js`. If you have any `.ts` files located in the root directory of your project (and your `tsconfig.json` configured to compile them), they will be copied to the `dist` directory as well, modifying the directory structure a bit (instead of `dist/main.js`, you will have `dist/src/main.js` so keep that in mind when configuring your server).
