Bedrock

Bedrock is a minimal Markdown-focused text editor built with Electron + React + CodeMirror 6.

Features

• Single-window editor
• Open/Save/Save As Markdown files (.md)
• Hybrid Markdown mode (renders structure while editing) + raw mode
• Customizable keybindings (Settings)
• Themes + UI scaling

Development

• Install: npm install
• Run (dev): npm start
• Lint: npm run lint
• Tests: npm test
• Package/build:
  • npm run package
  • npm run build

Architecture (high level)

• Main process: src/main/index.ts
  • Owns file dialogs + file IO
  • Exposes safe operations via IPC handlers
• Preload: src/main/preload.ts
  • Exposes a typed window.electronAPI surface (no Node integration in renderer)
• Renderer: src/renderer/app.tsx
  • Hosts the React app and wires CodeMirrorEditor
• Editor:
  • src/renderer/components/CodeMirrorEditor.tsx mounts CodeMirror, reconfigures extensions
  • src/renderer/editor/codemirror/* contains CodeMirror extensions (hybrid Markdown decorations, theme, keymaps, commands)

IPC surface

The renderer only talks to Electron via window.electronAPI (typed in src/shared/types.ts).

Security

• Renderer runs without Node integration.
• File system access is confined to the main process.
• External URL opening is validated in main (http(s) only).
