How to I setup typescript in vs code?
You need to be a bit more specific about what you are having troubles with. That said, VSCode doesn't require any special setup to work with typescript. All you have to do is open VSCode on the root folder of your project (package). For this, first initialize a project (e.g. with npm init), install typescript (either globally or local to the project, e.g. with npm i -D typescript), initialize your typescript config (e.g. with npx tsc --init), and finally open VSCode on the root folder of your project (i.e. where the package.json file generated by the init command is located). After that you have all that you need. You can then further customize typescript (though I would recommend you lookup a tutorial with a basic configuration that works well or, if you prefer, I can put one here) by changing the typescript config file (tsconfig.json) and/or the package config file (package.json) depending on what you wanna do. There are extensions to help with VSCode integration with typescript (like display better types, better errors, linting based on configuration, formatting, etc). But you should focus on learning typescript first and only then learn those additional configurations. More on reddit.com

Why can't I do npm install after setting up eslint with TypeScript?
You are likely using eslint 9.x version. Use 8.56.x version which should resolve the issue. The latest eslint-ts version is incompatible with eslint 9.x version. You'll need to use the 8.x version for now. More on reddit.com

r/node on Reddit: Why Do I Need to Install TypeScript Types for Every Package in Express.js but Not in Fastify.js?
September 6, 2024 -
I'm working on an Express.js project with TypeScript, and I always need to install types for every package I use, like @types, and others. However, when I switch to Fastify.js with TypeScript, I notice that I often don't need to install types separately for libraries.
Why is this happening? Is there something I'm doing wrong with my Express setup, or is there a specific reason for this difference? Any help or clarification would be appreciated!

Node, Express and JavaScript were around before TypeScript became a thing. The express package is simply written in JavaScript and does not contain any type definitions. This is also the case for many of the supporting packages of express. @types/* packages are community created packages to add TypeScript types to packages that don't already have them. Newer packages like fastify are either already written in TypeScript itself or just provide the type definitions by themselves alongside the JavaScript code.

A few tips in order
- restart the terminal
- restart the machine
- reinstall nodejs + then run
npm install typescript -g
If it still doesn't work run npm config get prefix to see where npm install -g is putting files (append bin to the output) and make sure that they are in the path (the node js setup does this. Maybe you forgot to tick that option).

You are all messing with the global installations and -path files. Just a little error might damage every project you have ever written, and you will spend the rest of the night trying to get a console.log('hi') to work again.
If you have run npm i typescript --save-dev in your project - just try to run:
npx tsc
And see if it works before messing with global stuff (unless of course you really know what you are doing)
