​
Accessing Configuration

The configuration is loaded when the application starts:
  1. The frontend fetches configuration from the /config endpoint
  2. Configuration is stored in the config Svelte store
  3. Components can access config values using $config.monaco.fontSize, etc.

​

  • Font: Fira Code with ligatures support
