1. Who am I and what is xbar?
   • @matryer: open source, author, @GoTimeFM podcast
   • xbar demo
2. Project structure
   • simple
   • monorepo contains everything: app front-end, app back-end, tools, website
3. Wails
   • xbar uses Wails by Lea Anthony
   • Wails is currently getting a v2 rewrite (which xbar uses)
   • build and package multi-platform desktop apps for Go https://wails.app
   • delivers a WebView, handles os calls, client and "server" RPC
4. Front-end
   • Svelte https://svelte.dev/
     • components contain markup, script, and style
     • does its work at compile time
     • very fast
   • Tailwind CSS
     • low-level CSS framework
     • fine tuned control
     • dark mode ;)
5. The Go Back-end
   • main.go just kicks off Wails app
   • app.Start callback
   • clearCache - function abstractions
   • *wails.Runtime object
   • Parsing plugin output
     • Great candidate for TDD
     • Processing strings
     • Fuzzing?
   • Turning the output into Wails menus
   • The Plugins service
   • Incoming URLs
6. xbarapp.com
   • static site, generated by a custom tool
   • metadata extraction from GitHub repo
   • static API
