# 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.
## 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.
