Linux: Compile C++ to WebAssembly and JavaScript using Emscripten and CMake

Download and Install Emscripten

My preferred installation location is /home/user
Get the latest sdk: git clone https://github.com/emscripten-core/emsdk.git
Enter the cloned directory: cd emsdk
Install the lastest sdk tools: ./emsdk install latest
Activate the latest sdk tools: ./emsdk activate latest
Activate path variables: source ./emsdk_env.sh
Configure emsdk in your bash profile by running: echo 'source "/home/user/emsdk/emsdk_env.sh"' >> $HOME/.bash_profile

It's 2024. You should use tsup instead of this.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
