Raycast Extension Development Skill

Raycast Extension Development

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

Quick Start

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

Choosing a UI Primitive

| Need | Component | |------|-----------| | Searchable list of items | List | | Image gallery/grid | Grid | | User input collection | Form | | Rich content display | Detail | | Status bar presence | MenuBarExtra |

Decision Tree

Displaying items the user searches/filters?
- Text-focused → List
- Image-focused → Grid
Collecting user input? → Form
Showing detailed content? → Detail (supports markdown + metadata)
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).
