# kbar



kbar is a simple plug-n-play React component to add a fast, portable, and extensible command + k (command palette) interface to your site.



![demo](https://user-images.githubusercontent.com/12195101/143491194-1d3ad5d6-24ac-4e6e-8867-65f643ac2d24.gif)



## Background



Command + k interfaces are used to create a web experience where any type of action users would be able to do via clicking can be done through a command menu.



With macOS's Spotlight and Linear's command + k experience in mind, kbar aims to be a simple

abstraction to add a fast and extensible command + k menu to your site.



## Features



- Built in animations and fully customizable components

- Keyboard navigation support; e.g. control + n or control + p for the navigation wizards

- Keyboard shortcuts support for registering keystrokes to specific actions; e.g. hit t

  for Twitter, hit ? to immediate bring up documentation search

- Nested actions enable creation of rich navigation experiences; e.g. hit backspace to navigate to

  the previous action

- Performance as a first class priority; tens of thousands of actions? No problem.

- History management; easily add undo and redo to each action

- Built in screen reader support

- A simple data structure which enables anyone to easily build their own custom components



### Usage



Have a fully functioning command menu for your site in minutes. First, install kbar.



```

npm install kbar

```



There is a single provider which you will wrap your app around; you do not have to wrap your

_entire_ app; however, there are no performance implications by doing so.



```tsx

// app.tsx

import { KBarProvider } from "kbar";



function MyApp() {

  return (

    

      // ...

    

  );

}

```



Let's add a few default actions. Actions are the core of kbar – an action define what to execute

when a user selects it.



```tsx

  const actions = [

    {

      id: "blog",

      name: "Blog",

      shortcut: ["b"],

      keywords: "writing words",

      perform: () => (window.location.pathname = "blog"),

    },

    {

      id: "contact",

      name: "Contact",

      shortcut: ["c"],

      keywords: "email",

      perform: () => (window.location.pathname = "contact"),

    },

  ]



  return (

    

      // ...

    

  );

}

```



Next, we will pull in the provided UI components from kbar:



```tsx

// app.tsx

import {

  KBarProvider,

  KBarPortal,

  KBarPositioner,

  KBarAnimator,

  KBarSearch,

  useMatches,

  NO_GROUP

} from "kbar";



// ...

  return (

    

       // Renders the content outside the root node

         // Centers the content

           // Handles the show/hide and height animations

             // Search input

          

        

      

      

    ;

  );

}

```



At this point hitting cmd+k (macOS) or ctrl+k (Linux/Windows) will animate in a search input and nothing more.



kbar provides a few utilities to render a performant list of search results.



- `useMatches` at its core returns a flattened list of results and group name based on the current

  search query; i.e. `["Section name", Action, Action, "Another section name", Action, Action]`

- `KBarResults` renders a performant virtualized list of these results



Combine the two utilities to create a powerful search interface:



```tsx

import {

  // ...

  KBarResults,

  useMatches,

  NO_GROUP,

} from "kbar";



// ...

// 

//   

;

// ...



function RenderResults() {

  const { results } = useMatches();



  return (

    

        typeof item === "string" ? (

          
{item}


        ) : (

          


            {item.name}

          


        )

      }

    />

  );

}

```



Hit cmd+k (macOS) or ctrl+k (Linux/Windows) and you should see a primitive command menu. kbar allows you to have full control over all

aspects of your command menu – refer to the docs to get

an understanding of further capabilities. Looking forward to see what you build.
