Crea un plugin en 5 minutos

Todo funciona con JavaScript — el SDK viene con Yoki, sin npm install. Esta guía te lleva paso a paso para crear tu primer plugin.

mkdir ~/yoki/plugins/my-plugin

{
  "name": "My Plugin",
  "keyword": "my",
  "icon": "star",
  "version": "1.0.0",
  "protocol": "v2",
  "commands": [
    {
      "name": "main",
      "title": "My Plugin",
      "mode": "detail",
      "exec": "main.js",
      "takes_query": true
    }
  ]
}

const { readInput, writeResponse, detail } = require("@yoki/plugin-sdk")

async function main() {
  const input = await readInput()
  const query = input.query || ""

  if (!query) {
    writeResponse(detail('<div style="padding:16px;color:#888">Type something after <b>my</b></div>'))
    return
  }

  writeResponse(detail(
    `<div style="padding:16px">
      <div style="font-size:24px;font-weight:bold;color:#4FC3F7">${query.toUpperCase()}</div>
      <div style="margin-top:8px;color:#888">Your input, uppercased</div>
    </div>`,
    [{ label: "Original", value: query }, { label: "Result", value: query.toUpperCase() }],
    [{ title: "Copy result", type: "copy", value: query.toUpperCase() }]
  ))
}
main()

echo '{"query":"hello world","command":"main","context":{}}' | node main.js

{"type":"detail","markdown":"<div style=\"padding:16px\"><div style=\"font-size:24px;font-weight:bold;color:#4FC3F7\">HELLO WORLD</div><div style=\"margin-top:8px;color:#888\">Your input, uppercased</div></div>","metadata":[{"label":"Original","value":"hello world"},{"label":"Result","value":"HELLO WORLD"}],"actions":[{"title":"Copy result","type":"copy","value":"HELLO WORLD"}]}

const { readInput, writeResponse, detail, list, background, error, stripKeyword, escHtml } = require("@yoki/plugin-sdk")

readInput()

Reads what the user typed and context from Yoki. Call this once at the start of your script. Returns an object with the user's query, which command was triggered, and context (paths, locale, credentials).

async readInput(): Promise<object>

const input = await readInput()
const query = input.query  // "hello world"

const input = await readInput()
const dataDir = input.context.data_dir
// e.g. "C:/Users/you/yoki/plugins/my-plugin/data"
// Use this to store config, cache, tokens — it persists across runs

const input = await readInput()
const apiKey = input.context.credentials?.api_key || ""
if (!apiKey) {
  writeResponse(error("API key not configured"))
  return
}

// input = {
//   query: "hello world",         — what the user typed after keyword
//   command: "main",              — which command (from plugin.json)
//   action: "search",             — "search" | "execute" | "refresh"
//   context: {
//     yoki_version: "1.0.8.2",
//     os: "windows",
//     locale: "en",               — user's language
//     plugin_dir: "C:/.../my-plugin",
//     data_dir: "C:/.../my-plugin/data",
//     credentials: { ... }        — from credentials service
//   },
//   preferences: {}
// }

writeResponse(resp)

Sends your response back to Yoki. Call this once at the end of your script. Pass the result from any builder function — detail(), list(), error(), etc.

writeResponse(resp: object): void

writeResponse(detail("<div>Hello!</div>"))

writeResponse(error("Something went wrong", "Please try again later"))

detail(html, metadata?, actions?)

Shows a rich card with HTML content, a metadata sidebar, and action buttons. When the user presses Enter, the first action with type "copy" is triggered.

detail(
  html: string,
  metadata?: [{ label: string, value: string }, ...],
  actions?:  [{ title: string, type: string, value?: string }, ...]
)

writeResponse(detail(
  '<div style="padding:16px;font-size:20px">Hello, World!</div>'
))

writeResponse(detail(
  '<div style="padding:16px"><h2>2 + 2 = 4</h2></div>',
  [
    { label: "Hex", value: "0x4" },
    { label: "Binary", value: "0b100" },
    { label: "Prime", value: "No" }
  ]
))

writeResponse(detail(
  '<div style="padding:16px;font-size:24px;color:#4FC3F7">42</div>',
  [{ label: "Expression", value: "6 * 7" }],
  [{ title: "Copy result", type: "copy", value: "42" }]
))

writeResponse(detail(
  '<div style="padding:16px"><h2>Now Playing</h2><p>Mind Mirage — Windows 96</p></div>',
  [{ label: "Duration", value: "5:00" }],
  [
    { title: "Pause", type: "yoki_run", value: "sp pause", variant: "primary" },
    { title: "Next", type: "yoki_run", value: "sp next" },
    { title: "Copy track", type: "copy", value: "Mind Mirage — Windows 96" },
    { title: "Open in Spotify", type: "open_url", url: "https://open.spotify.com/track/..." }
  ]
))

list(items)

Shows a scrollable list of items. Each item has a title, subtitle, icon, and optional actions. Use for search results, bookmarks, file lists.

list(items: [{
  id: string, title: string, subtitle?: string,
  icon?: string, actions?: Action[]
}, ...])

writeResponse(list([
  { id: "1", title: "First result", subtitle: "Description here" },
  { id: "2", title: "Second result", subtitle: "Another description" },
]))

writeResponse(list([
  {
    id: "gh",
    title: "GitHub",
    subtitle: "https://github.com  ·  Bookmarks Bar",
    icon: "🌐",
    actions: [
      { title: "Open", shortcut: "enter", type: "open_url", url: "https://github.com" },
      { title: "Copy URL", shortcut: "cmd+c", type: "copy", value: "https://github.com" }
    ]
  }
]))

const input = await readInput()
const query = input.query.toLowerCase()

const allItems = [
  { id: "1", title: "GitHub", subtitle: "Code hosting" },
  { id: "2", title: "Google", subtitle: "Search engine" },
  { id: "3", title: "Gmail", subtitle: "Email" },
]

const filtered = query
  ? allItems.filter(i => i.title.toLowerCase().includes(query))
  : allItems

writeResponse(list(filtered))

background(hud, notification?)

Runs an action without showing any UI. Shows a brief HUD toast. Optionally sends a system notification. The user must press Enter to trigger it (never fires on keystroke). Use for play/pause, save, toggle.

background(hud: string, notification?: { title: string, body: string })

writeResponse(background("Done!"))

writeResponse(background(
  "Playing: Mind Mirage",
  { title: "Spotify", body: "Now playing: Mind Mirage — Windows 96" }
))

error(message, details?)

Shows an error message to the user. Use when something goes wrong — missing input, API failure, runtime not installed. Plugin crashes are also caught automatically.

error(message: string, details?: string)

writeResponse(error("Not found"))

writeResponse(error("API request failed", "Check your internet connection and try again"))

const input = await readInput()
if (!input.query) {
  writeResponse(error("No query", "Type something after the keyword"))
  return
}

stripKeyword(query, ...keywords)

Removes a keyword prefix from the query string. Useful when your plugin has subcommands (e.g. "search", "play", "list").

stripKeyword(query: string, ...keywords: string[]): string

stripKeyword("search hello world", "search", "s")
// → "hello world"

stripKeyword("s hello world", "search", "s")
// → "hello world"  (matches short alias too)

stripKeyword("search", "search", "s")
// → ""  (exact match returns empty string)

escHtml(str)

Escapes HTML special characters (&, <, >, "). Use this when inserting user input into your HTML to prevent broken rendering or XSS.

escHtml(s: string): string

const input = await readInput()
const safe = escHtml(input.query)
writeResponse(detail(`<div>${safe}</div>`))

// input: "<b>bold</b>"
// safe:  "&lt;b&gt;bold&lt;/b&gt;"
// renders as text, not HTML

writeResponse(detail(
  '<div style="padding:16px"><h2>Now Playing</h2><p>Mind Mirage — Windows 96</p></div>',
  [{ label: "Duration", value: "5:00" }, { label: "Album", value: "Enchanted Instrumentals" }],
  [{ title: "Pause", type: "yoki_run", value: "sp pause", variant: "primary" },
   { title: "Copy", type: "copy", value: "Mind Mirage" }]
))

writeResponse(list([
  { id: "1", title: "Mind Mirage", subtitle: "Windows 96 · 5:00", icon: "music",
    actions: [{ title: "Play", type: "yoki_run", value: "sp play spotify:track:xyz" },
              { title: "Copy", type: "copy", value: "Mind Mirage" }] }
]))
