Slack, Notion, and VSCode Improved Electron App Performance

a year ago

Electron apps can rival native app performance with proper optimization.
Main performance challenges: slow startup and poor interaction performance.
Key strategies include using bundlers (Webpack, esbuild, Vite) to replace synchronous `require()` calls.
Defer non-critical imports using route-based code splitting and async imports.
Migrate computationally expensive tasks to WebAssembly or native modules for better performance.
Use V8 snapshots to reduce initialization time, as demonstrated by Atom and VSCode teams.
Monitor end-user performance metrics like click latency, keypress latency, and scroll latency.
Implement production JavaScript profiling to identify and fix performance bottlenecks.
Notion improved performance metrics by 15-20% using production profiling tools like Palette.
