How codexeron/web-playground works

Web Playground is a client-side browser IDE: users edit project files, see the generated page in an isolated preview, and inspect runtime feedback. The main runtime logic is concentrated in js/app.js; the README documents the broader file, responsive, theme, monitoring, and persistence capabilities. The excerpts show editor autosave/preview triggers and iframe message handling, but omit much of the implementation, so uncertain wiring is not shown.

Main entry points: index Playground UI · app.js Code editor · preview Separate-tab preview
