Preferences

Use the Preferences API to make your extension configurable.
Preferences are configured in the manifest per command or shared in the context of an extension.
Required preferences need to be set by the user before a command opens. They are a great way to make sure that the user of your extension has everything set up properly.

API Reference

getPreferenceValues

A function to access the preference values that have been passed to the command.
Each preference name is mapped to its value, and the defined default values are used as fallback values.

Signature

function getPreferenceValues(): { [preferenceName: string]: any };

Example

import { getPreferenceValues } from "@raycast/api";
interface Preferences {
name: string;
bodyWeight?: string;
bodyHeight?: string;
}
export default async function Command() {
const preferences = getPreferenceValues<Preferences>();
console.log(preferences);
}

Return

An object with the preference names as property key and the typed value as property value.
Depending on the type of the preference, the type of its value will be different.

const markdown = "API key incorrect. Please update it in extension preferences and try again.";
return (
<Detail
markdown={markdown}
actions={
<ActionPanel>
<Action title="Open Extension Preferences" onAction={openExtensionPreferences} />
</ActionPanel>
}
/>
);
}

Signature

export declare function openCommandPreferences(): Promise<void>;

Example

import { ActionPanel, Action, Detail, openCommandPreferences } from "@raycast/api";
export default function Command() {
const markdown = "API key incorrect. Please update it in command preferences and try again.";
return (
<Detail
markdown={markdown}
actions={
<ActionPanel>
<Action title="Open Extension Preferences" onAction={openCommandPreferences} />
</ActionPanel>
}
/>
);
}

Types

Preferences

A command receives the values of its preferences via the getPreferenceValues function. It is an object with the preferences' name as keys and their values as the property's values.
Depending on the type of the preference, the type of its value will be different.
Preference type
Value type
textfield
string
password
string
checkbox
boolean
dropdown
string
appPicker
file
string
directory

Raycast provides a global TypeScript namespace called Preferences which contains the types of the preferences of all the commands of the extensions.
For example, if a command named show-todos has some preferences, its getPreferenceValues's return type can be specified with getPreferenceValues<Preferences.ShowTodos>(). This will make sure that the types used in the command stay in sync with the manifest.
