Example usage
You can compose your command palette pretty much however you like with the included components. But here is an example of a command palette that uses some of the included helpers for a very neat solution.
import "react-cmdk/dist/cmdk.css";
import CommandPalette, { filterItems, getItemIndex } from "react-cmdk";
import { useState } from "react";
const Example = () => {
const [page, setPage] = useState<"root" | "projects">("root");
const [open, setOpen] = useState<boolean>(true);
const [search, setSearch] = useState("");
const filteredItems = filterItems(
[
{
heading: "Home",
id: "home",
items: [
{
id: "home",
children: "Home",
icon: "HomeIcon",
href: "#",
},
{
id: "settings",
children: "Settings",
icon: "CogIcon",
href: "#",
},
{
id: "projects",
children: "Projects",
icon: "RectangleStackIcon",
closeOnSelect: false,
onClick: () => {
setPage("projects");
},
},
],
},
{
heading: "Other",
id: "advanced",
items: [
{
id: "developer-settings",
children: "Developer settings",
icon: "CodeBracketIcon",
href: "#",
},
{
id: "privacy-policy",
children: "Privacy policy",
icon: "LifebuoyIcon",
href: "#",
},
{
id: "log-out",
children: "Log out",
icon: "ArrowRightOnRectangleIcon",
onClick: () => {
alert("Logging out...");
},
},
],
},
],
search
);
return (
<CommandPalette
onChangeSearch={setSearch}
onChangeOpen={setOpen}
search={search}
isOpen={open}
page={page}
>
<CommandPalette.Page id="root">
{filteredItems.length ? (
filteredItems.map((list) => (
<CommandPalette.List key={list.id} heading={list.heading}>
{list.items.map(({ id, ...rest }) => (
<CommandPalette.ListItem
key={id}
index={getItemIndex(filteredItems, id)}
{...rest}
/>
))}
</CommandPalette.List>
))
) : (
<CommandPalette.FreeSearchAction />
)}
</CommandPalette.Page>
<CommandPalette.Page id="projects">
{/* Projects page */}
</CommandPalette.Page>
</CommandPalette>
);
};
export default Example;
Opening the command palelette
The package does include a helper hook for opening the command palette, but you can actually open it however you want. Here are some examples.
Helper
const [isOpen, setIsOpen] = useState<boolean>(false);
useHandleOpenCommandPalette(setIsOpen);
Custom
const [isOpen, setIsOpen] = useState<boolean>(false);
useEffect(() => {
function handleKeyDown(e: KeyboardEvent) {
if (e.metaKey && e.key === "k") {
e.preventDefault();
e.stopPropagation();
setIsOpen((currentValue) => {
return !currentValue;
});
}
}
document.addEventListener("keydown", handleKeyDown);
return () => {
document.removeEventListener("keydown", handleKeyDown);
};
}, []);
