Plugin API reference

The PluginAPI object is passed to your register function and is the only interface to the host app.

api.pluginId — string

Your plugin's ID as declared in manifest.json.

api.isActive()

isActive(): boolean

Returns true if the plugin is currently enabled. Use this in register() to skip setup when disabled:

export default function register(api: PluginAPI) {
  if (!api.isActive()) return;
  // ...
}

api.connections — requires connections:read / connections:write

api.connections.list()                                // Promise<PluginConnection[]>
api.connections.get(id)                               // Promise<PluginConnection | null>
api.connections.create(data: PluginConnectionInput)   // Promise<PluginConnection>
api.connections.update(id, data)                      // Promise<void>
api.connections.delete(id)                            // Promise<void>
api.connections.bulkImport(items)                     // Promise<PluginConnection[]>
api.connections.subscribe(cb)                         // () => void  (unsubscribe)

PluginConnection:

interface PluginConnection {
  id: string;
  name?: string;
  host: string;
  port: number;
  username: string;
  auth_type: "password" | "key";
  tags: string[];
  identity_id?: string;
  jump_hosts?: JumpHost[];
}

PluginConnectionInput is the same shape without id, with all fields except host, port, username, and auth_type being optional.

api.keys — requires keys:read / keys:write

api.keys.list()                              // Promise<PluginKey[]>
api.keys.create(data, privateKey, publicKey?) // Promise<PluginKey>
api.keys.delete(id)                          // Promise<void>

data for create: { name?: string; key_type?: string; tags?: string[] }

PluginKey:

interface PluginKey {
  id: string;
  name?: string;
  key_type?: string;
  tags: string[];
}

api.identities — requires identities:read / identities:write

api.identities.list()                                          // Promise<PluginIdentity[]>
api.identities.create({ name?, username, key_id?, tags? })     // Promise<PluginIdentity>
api.identities.delete(id)                                      // Promise<void>

PluginIdentity:

interface PluginIdentity {
  id: string;
  name?: string;
  username: string;
  key_id?: string;
  tags: string[];
}

api.vault — requires vault:*

Encrypted key-value store for secrets. Scoped to your plugin — keys are stored as plugin:<id>:<key> and are never accessible to other plugins.

api.vault.get(key)           // Promise<string | null>
api.vault.set(key, value)    // Promise<void>
api.vault.delete(key)        // Promise<void>

Tip

Use vault for sensitive data (tokens, passwords). Use storage for non-sensitive config.

api.storage — always available

JSON key-value store persisted to disk ($APP_DATA/plugin-data/<id>.json). Not encrypted.

api.storage.get<T>(key)      // Promise<T | null>
api.storage.set<T>(key, val) // Promise<void>
api.storage.delete(key)      // Promise<void>

api.omni — requires omni-commands

Register commands in the Command Palette (Cmd+K / Ctrl+K):

api.omni.register({
  id: "my-cmd",
  label: "Do something",
  icon: "lucide:zap",           // Iconify icon ID
  keywords: ["something", "do"],
  section: "My Plugin",
  keybinding: "ctrl+shift+d",   // optional, first-registered wins on conflict
  execute: async () => { /* ... */ },
})  // returns () => void cleanup

api.omni.unregister(id)

api.ui — requires matching permission per method

// Requires "settings-page"
// For plain settings, prefer the declarative `contributes.configuration` schema
// (see Developing → Configuration schema) — the host renders a consistent form
// with no UI code. Register a page only for bespoke UIs.
api.ui.registerSettingsPage({ id, label, icon, component: React.FC })

// Requires "sidebar-item"
api.ui.registerSidebarItem({ id, label, icon, component: React.FC, position?: "top" | "bottom" })

// Requires "right-panel"
api.ui.registerRightPanelSection({ id, label, icon, component: React.FC })

// Requires "context-menu"
api.ui.registerContextMenuItem({
  id, label, icon?,
  target: "connection" | "session" | "tab" | Array,
  action: (ctx: ContextMenuContext) => void,
})

// Requires "ui-contributions"
api.ui.registerContribution(slot, (ctx) => ContributedAction[])

// Requires "ui-contributions"
api.ui.registerStatusBarItem("terminal.statusBar.right", (ctx) => ReactNode)

All register methods return a cleanup () => void.

Available UISlot values:

"connection.contextMenu"    "connection.panelActions"
"key.contextMenu"           "key.panelActions"
"identity.contextMenu"      "identity.panelActions"
"home.bgContextMenu"        "keychain.bgContextMenu"
"home.toolbar.hostMenu"     "settings.vaults"

ContributedAction:

interface ContributedAction {
  label: string;
  icon?: string;
  onClick: () => void;
  divider?: boolean;
  danger?: boolean;
  shortcut?: string;
  when?: (context: unknown) => boolean; // sync only — errors treated as false
}

api.themes — requires themes

api.themes.register(theme: PluginTheme)  // same shape as AppTheme
api.themes.unregister(id: string)

api.sessions — requires sessions:read / sessions:write

api.sessions.list()                          // PluginSession[]  (snapshot)
api.sessions.onConnected(cb)                 // () => void
api.sessions.onDisconnected(cb)              // () => void
api.sessions.onActivated(cb)                 // () => void  (tab switch)
api.sessions.sendCommand(sessionId, cmd)     // Promise<void>  — requires sessions:write

sendCommand writes to the terminal; the runtime appends \n. Works for SSH sessions and local shells.

Warning

sendCommand is intentionally powerful. Users are responsible for the plugins they install.

api.lifecycle — always available

api.lifecycle.onConnectionEstablished(cb)   // fires when a session becomes "connected"
api.lifecycle.onConnectionClosed(cb)        // fires on disconnect / removal
api.lifecycle.onSessionActivated(cb)        // fires on active tab change
api.lifecycle.onSettingsChanged(cb)         // fires when storage.set() is called for this plugin
api.lifecycle.onBeforeQuit(cb)              // max 5s before app force-quits
api.lifecycle.waitForLoginSync()            // Promise<void> — resolves after login-time sync

All event hooks return a cleanup () => void.

api.http — requires http

api.http.get<T>(url, opts?)         // Promise<T>  — throws on non-2xx
api.http.post<T>(url, body, opts?)  // Promise<T>  — sets Content-Type: application/json

api.fs — requires fs

Paths are relative to the user's home directory (~).

api.fs.readText(path)                           // Promise<string>
api.fs.writeText(path, content)                 // Promise<void>
api.fs.exists(path)                             // Promise<boolean>
api.fs.watch(path, cb, { intervalMs?: number }) // () => void  (polling-based)

api.notifications — requires notifications

api.notifications.toast(message, {
  severity?: "info" | "success" | "warning" | "error",
  duration?: number,   // ms, default 2500
  action?: { label: string; onClick: () => void },
})

const progress = api.notifications.progress("Uploading...", {
  indeterminate?: boolean,   // default true
  cancellable?: boolean,
})
progress.update(50, "Halfway there")
progress.finish("Done!")
progress.error("Something went wrong")

const banner = api.notifications.banner("Update available", {
  severity?: "info" | "success" | "warning" | "error",
  actions?: Array<{ label: string; onClick: () => void }>,
  dismissable?: boolean,
  flashToast?: boolean,  // also shows a toast, default true
})
banner.dismiss()
banner.update("New message")

api.sync — requires sync:read / sync:write

Binary blob storage for sync scenarios. Max 1 MB per blob.

api.sync.getBlob(key)                  // Promise<Uint8Array | null>
api.sync.setBlob(key, data)            // Promise<void>  — throws if > 1 MB
api.sync.onRemoteChange(key, cb)       // () => void  — fires after sync if blob changed
api.sync.triggerReload(storeKey)       // Promise<void>
api.sync.exportState(encKey, deviceId) // Promise<string>  — base64 encrypted blob
api.sync.importStates(encKey, blobs)   // Promise<void>  — CRDT-merge remote blobs

triggerReload accepts: "connections", "identities", "keys", "snippets", "folders".

api.events — always available

Shared event bus. Emitted events are automatically prefixed with the plugin ID (<pluginId>:<event>). Listen to another plugin's events using the full prefixed name.

// Plugin A emits
api.events.emit("synced", { count: 5 })
// → fires handlers for "plugin-a:synced"

// Plugin B listens
api.events.on("plugin-a:synced", (data) => { /* ... */ })

api.plugins — always available

api.plugins.expose({ doThing: () => {} })   // publish your public API
api.plugins.getApi("other-plugin-id")       // unknown | null

api.log — always available

Console output scoped to your plugin ([plugin:<id>] prefix):

api.log.info("message", ...args)
api.log.warn("message", ...args)
api.log.error("message", ...args)

Permissions

Declare these in manifest.json under "permissions". The runtime throws if you call an API without the required permission.
