typescript-node | : clipboard : TypeScript and NodeJS project template | Runtime Evironment library

I am trying to dynamically build chartContainers based on a MongoDB Database. For some background, I am using CanvasJS to create stock charts. I have a "stocks" variable I iterate through which is an array of all the elements in my database. This is my first web development project and my first time using javascript and pug so apologies if there is an obvious question. For reference, I built this project using this template

I would like to have an application, database and redis service running in a dev container where I'd be able to access my database and redis inside the container, application and on Windows, this is what currently works just as I wanted for my application and database:

.devcontainer.json:

Windows 10 Docker Desktop on WSL2

Goal: serve an angular app from my devcontainer over my local network (specifically for testing on mobile)

Reproduce:

1. Create a hello world angular application in a clean git repo
2. clone the repo into a new devcontainer (Typescript/Node)
3. serve the applcation

Things I've tried (and every permutation herein):

• --network=host (Never worked on windows, but thought it might on WSL2 - doesn't)
• EXPOSE 4200
• runArgs: "-p 4200:4200"
• appPort: [4200]
• opening port 4200 on PC firewall
• ng serve --host 0.0.0.0 --port 4200

Additional Information:

• ng serve does allow me to view the site on my host machine
• cloning the repo to my host and running ng serve --host 0.0.0.0 does allow me to access the site over my network (but moving in and out of the devcontainer isn't reasonable)

My current DockerFile is pretty vanilla:

There's quite a few questions in SO about running a React App in Docker, and while I believe I'm following the instructions to the letter, it's still not working for me and was wondering if anyone has a clear solution.

In short I have the following in my Dockerfile

I am creating a Node/Express API using Microsoft's Typescript Node Starter Project - https://github.com/microsoft/TypeScript-Node-Starter

When I build the project it's inserting semicolons in all my code. Not the compiled code in /dist, but the source code in /src which I don't want semicolons in.

The package.json has the following scripts (abbreviated)

tsconfig.json

I am encountering a problem where I get the error TypeError: Cannot read property 'doFileHasCorrectFileExtension' of undefined when I create an file or an folder. I expect my application to be able to use the method doFileHasCorrectFileExtension without having it being undefined.

As an attempt to solve my problem I created an variable that hold the object created by the class.

it isnt a typescript, but ts-node "issue"

i answered to myself so if ure still interested in the "issue" - read further :)

sorry for the confusion

maybe I have a TOTALLY wrong idea of the index.d.ts file.. but my idea was, that i can declare types within it and they are then "globally defined", so i dont have to redeclare them everywhere i use them (file a.ts and b.ts)

structure:

Partially solved:

There is an old issue on github where this problem is described a bit. When you declare a module in a global scope, it rewrites the whole exported module's types. When you declare a module inside a module, it merges. Why? I have no idea

https://github.com/microsoft/TypeScript/issues/17736#issuecomment-344353174

I want to extend third party module's type by interface merging. Everything works fine, but when I comment export {}; in types.d.ts I encounter the following error:

This expression is not callable. Type 'typeof import("koa-session")' has no call signatures

Could you explain why it happens?
