What tools would you use to build a new personal project in 2022?

Ubuntu 22.04 LTS desktop with gcc, make, autoconf, nano, git, github

I'm working on a fork of Kamby, and a descendant of STOIC, both written in C, which I'm learning for these projects after avoiding it for 40 years.

Depends on the project.

Static website: - Svelte with SvelteKit.

Fullstack website: - Svelte, a NodeJS server hooked up to some nosql DB like MongoDB. Might even use Firebase (depending on data structure).

Mobile app: - Flutter or react-native.

VSCode as IDE/text editor.

I'd be interested in giving some of the WASM frameworks a try, like blazor or yew.

Well, it depends.

autotools, gnumake, gcc, groff.

Or, python3, fastapi, postgresql.

Or, HTML5, CSS3, Vanilla.JS.
