SilverBullet at its core is bare bones in terms of functionality, most of its power it gains from plugs and Space Lua.

Plugs are an extension mechanism that runs “plug” code in the browser using web workers.

Plugs can hook into SB in various ways:

• Extend the Markdown parser and its syntax
• Define new commands and keybindings
• Respond to various events triggered either on the server or client-side
• Run recurring and background tasks.
• Define their own extension mechanisms through custom events

Each plug runs in its own sandboxed environment and communicates with SB via syscalls that expose a vast range of functionality. Plugs can be loaded, unloaded, and updated without having to restart SilverBullet itself.

Plugs are distributed as self-contained JavaScript bundles (ending with .plug.js). SilverBullet will load all core plugs bundled with SB itself (listed below), as well as any additional plugs stored in the _plug folder in your space.

Third-party plugs

The SilverBullet ‘Plugs’ category has a list of third-party plugs you can try.
