There are various copy-to-clipboard solutions for Javascript β really good ones, but getting them to work with React can feel a little odd... they don't feel very React-y.
use-clipboard-copy
is a lightweight (< 1KB) React hook that makes it possible to add a copy-to-clipboard functionality to your React application with very little code! A simple implementation looks like this:
function CopyText() {
const clipboard = useClipboard();
return (
<div>
<input ref={clipboard.target} />
<button onClick={clipboard.copy}>Copy</button>
</div>
);
}
P.S. You can do more than that with use-clipboard-copy
. Keep reading!
To get started, add use-clipboard-copy
to your project:
npm install --save use-clipboard-copy
Please note that use-clipboard-copy
requires react@^16.8.0
as a peer dependency.
A simple copy-to-clipboard interface consists of two parts:
- The
target
, an element who holds the value to be copied, usually an input. - The
copy
action.
import { useClipboard } from 'use-clipboard-copy';
export default function PublicUrl({ url }) {
const clipboard = useClipboard();
return (
<div>
<input ref={clipboard.target} value={url} readOnly />
<button onClick={clipboard.copy}>Copy Link</button>
</div>
);
}
It is also possible to perform a copy action imperatively (programmatically). For example, a copy-to-clipboard interface may consist of a single copy button without any additional inputs or values displayed to the user. By passing a string to the clipboard.copy
action, the specified string will be copied to the clipboard.
import { useClipboard } from 'use-clipboard-copy';
export default function PublicUrl({ id }) {
const clipboard = useClipboard();
const handleClick = React.useCallback(
() => {
const url = Utils.formatUrl({ query: { id } });
clipboard.copy(url); // programmatically copying a value
},
[clipboard.copy, id]
);
return (
<button onClick={handleClick}>Copy Link</button>
);
}
Sometimes it can be helpful to notify the user that the text was successfully copied to the clipboard, usually by displaying a temporary "Copied" state after they trigger the copy action.
By passing the copiedTimeout
option to useClipboard()
, you can use clipboard.copied
as a way to toggle the copied state in the UI.
import { useClipboard } from 'use-clipboard-copy';
export default function PublicUrl({ url }) {
const clipboard = useClipboard({
copiedTimeout: 600, // timeout duration in milliseconds
});
return (
<div>
<input ref={clipboard.target} value={url} readOnly />
<button onClick={clipboard.copy}>
{clipboard.copied ? 'Copied' : 'Copy Link'}
</button>
</div>
);
}
Copy to clipboard in browsers can be tricky some times - there are various reasons that can contribute to preventing the copy action from working. Therefore, you should always handle such cases.
By passing an onSuccess
and onError
callbacks to the useClipboard
options, you will be able to handle whether the copy
action was performed successfully.
function CopyText() {
const clipboard = useClipboard({
onSuccess() {
console.log('Text was copied successfully!')
},
onError() {
console.log('Failed to copy text!')
}
});
return (
<div>
<input ref={clipboard.target} />
<button onClick={clipboard.copy}>Copy</button>
</div>
);
}
In case the copy
action fails, useClipboard
will handle that gracefully by selecting the target
input instead so that users can copy the text manually. This behavior can be disabled by passing selectOnError: false
to the clipboard options.
use-clipboard-copy
is supported in all browsers that supports the native clipboard APIs, including major browsers such as Chrome, Firefox, Edge, Safari, IE11.
This hook provides an isSupported
method that you can use to check for browser support and update the UI accordingly:
function ClipboardSupport() {
const clipboard = useClipboard();
return (
<div>
{clipboard.isSupported()
? "yay! copy-to-clipboard is supported"
: "meh. copy-to-clipboard is not supported"}
</div>
);
}
use-clipboard-copy
exposes a named export useClipboard
which is the hook function itself. It takes an optional options object, and returns an object to control the clipboard.
import { useClipboard } from 'use-clipboard-copy';
function CopyText() {
const clipboard = useClipboard();
return (
// ...
);
}
useClipboard
takes an optional object with the following properties:
copiedTimeout?: number
onSuccess?: () => void
onError?: () => void
selectOnCopy?: boolean
selectOnError?: boolean
The duration in milliseconds used to toggled the copied
state upon a successful copy action.
A callback function that will be called upon a successful copy action.
A callback function that will be called when the copy action fails.
Defaults to false
.
A boolean indicating whether the text of the target
element (if set) will be selected upon a successful copy action.
Defaults to true
.
A boolean indicating whether the text of the target
element (if set) will be selected when the copy action fails.
useClipboard
returns an object with the following properties:
copied: boolean
copy: (text?: string) => void
isSupported: () => boolean
target: React.RefObject<any>
A method that will be used to preform the copy action. If it's used without passing a string, the copy
action will use the text of the target
element (if set).
<input ref={clipboard.target} value="a text to copy" />;
<button onClick={clipboard.copy} />;
Optionally, copy
takes a string
to perform the copy action imperatively (programmatically). When this is used, the target
element (if set) will be ignored.
<button onClick={() => clipboard.copy('a text to copy')} />;
A React Ref object used on input and textarea elements that holds the text to be copied.
<input ref={clipboard.target} value="a text to copy" />;
A function that returns a boolean indicating whether the browser supports the clipboard APIs. Useful to deterministically update the UI if the browser does not support the clipboard functionality for whatever reason.
A boolean indicating whether the copy action was just performed. Must be used with the copiedTimeout
option. Useful to update the UI to display temporary success state.
This hook is powered by clipboard-copy, the lightweight copy to clipboard for the web.
