I’ve created a simple TS project with the following file structure:

root/
├── package.json
├── public/
│   ├── images/
│   ├── index.html
│   └── index.js
├── src/
│   └── index.ts
└── tsconfig.json

Where index.js is the compiled index.ts. The .ts file contains a single hello world console log.
In index.html I have the following line in my header tag:
<script src="../dist/index.js"></script>

Starting the server with http-server and opening the index.html file throws a 404 error for GET /dist/index.js.

However, moving index.js to the public folder and changing the script tag source to "index.js" makes it run perfectly fine. Moving index.js to the root folder and making the source ../index.js doesn’t work though.

To my understanding, ../ is supposed to refer to the directory above the current directory, so I don’t know why this wouldn’t work.
