Raycast Extension Development

Build Raycast extensions using React, TypeScript, and Node.js.

Quick Start

  1. Create extension: Run "Create Extension" command in Raycast
  2. Install & develop: npm install && npm run dev
  3. Edit: Modify src/index.tsx, changes hot-reload automatically
  4. Test: Extension appears at top of Raycast root search

Choosing a UI Primitive

NeedComponent
Searchable list of itemsList
Image gallery/gridGrid
User input collectionForm
Rich content displayDetail
Status bar presenceMenuBarExtra

Decision Tree

  1. Displaying items the user searches/filters?

    • Text-focused → List
    • Image-focused → Grid
  2. Collecting user input? → Form

  3. Showing detailed content? → Detail (supports markdown + metadata)

  4. Always-visible status bar? → MenuBarExtra

Core Patterns

List with ActionPanel

import { ActionPanel, Action, List } from "@raycast/api";

export default function Command() {
  return (
    <List>
      <List.Item
        title="Item"
        actions={
          <ActionPanel>
            <Action.CopyToClipboard content="Copied!" />
            <Action.OpenInBrowser url="https://raycast.com" />
          </ActionPanel>
        }
      />
    </List>
  );
}

Data Fetching

import { List } from "@raycast/api";
import { useFetch } from "@raycast/utils";

export default function Command() {
  const { data, isLoading } = useFetch<Item[]>("https://api.example.com/items");
  
  return (
    <List isLoading={isLoading}>
      {data?.map((item) => <List.Item key={item.id} title={item.name} />)}
    </List>
  );
}

AI Integration

import { AI, Clipboard } from "@raycast/api";

export default async function Command() {
  const answer = await AI.ask("Summarize this text");
  await Clipboard.copy(answer);
}

[!NOTE] AI requires Raycast Pro. Check access with environment.canAccess(AI).
