Show HN: A note-keeping system on top of Fossil SCM
I used a note system built on top of Fossil as my primary system for quite a while. Here are the details in case anyone is interested. Fossil allows CGI extensions[1]. There's a database for tickets, but that's just a regular SQLite table that you can use to store anything you want, and it's version controlled and queryable.

Writing a (simple) code editor for the web?

An experiment in UI density created with Svelte
VS Code Editor which is based on Electron, is really fast, even with large codebase & many open tabs.

It also uses WebGL + canvas rendering to show minimap of the file. Similar approach (custom virtual processor) is leveraged by Google docs/sheets. Canvas... - Source: Hacker News / 9 months ago

NPM workspace and vite - Read dependency build output (d.ts file)
So lets say the project consists of two packages Lib and App in which Lib is a library and App is the frontend app which depends on Lib. Now I want to display a monaco powered code editor in App which has has access to all types of Lib. This means that I have to somehow read the *.d.ts file of Lib as a string to set it as "extra lib" for monaco. Source: over 1 year ago
