Command

This set of utilities to work with Raycast commands.
API Reference
launchCommand
Launches another command. If the command does not exist, or if it's not enabled, an error will be thrown. If the command is part of another extension, the user will be presented with a permission alert. Use this method if your command needs to open another command based on user interaction, or when an immediate background refresh should be triggered, for example when a command needs to update an associated menu-bar command.
Signature
export async function launchCommand(options: LaunchOptions): Promise<void>;
Example
import { launchCommand, LaunchType } from "@raycast/api";
​
export default async function Command() {
  await launchCommand({ name: "list", type: LaunchType.UserInitiated, context: { foo: "bar" } });
}
Parameters
Name
Description
Type
options*
A parameter object with the properties: name: command name as defined in the extension's manifest type: LaunchType.UserInitiated or LaunchType.Background arguments: optional object for the argument properties and values as defined in the extension's manifest, for example: { "argument1": "value1" } context: arbitrary object for custom data that should be passed to the command and accessible as environment.launchContext; the object must be JSON serializable (Dates and Buffers supported)
​LaunchOptions​
Return
A Promise that resolves when the command has been launched. (Note that this does not indicate that the launched command has finished executing.)
updateCommandMetadata
Update the values of properties declared in the manifest of the current command. Note that currently only subtitle is supported. Pass null to clear the custom subtitle.
The actual manifest file is not modified, so the update applies as long as the command remains installed.
Signature
export async function updateCommandMetadata(metadata: { subtitle?: string | null }): Promise<void>;
Example
import { updateCommandMetadata } from "@raycast/api";
​
async function fetchUnreadNotificationCount() {
  return 10;
}
​
export default async function Command() {
  const count = await fetchUnreadNotificationCount();
  await updateCommandMetadata({ subtitle: `Unread Notifications: ${count}` });
}
Return
A Promise that resolves when the command's metadata have been updated.
