A Tauri plugin for clipboard read/write/monitor. Support text, rich text, HTML, files and image.
The reason I built this plugin is becasue official Tauri API only supports clipboard read and write for text, not image, HTML, rich text or files. So you can still use the official API for text. Update: V2 now supports text, HTML, and image.
If you are installing from npm and crate.io package registry, make sure the versions for both packages are the same, otherwise, the API may not match.
I will make sure the latest version is published to both npm and crates.io.
Crate: https://crates.io/crates/tauri-plugin-clipboard
NPM Package: https://www.npmjs.com/package/tauri-plugin-clipboard-api
cargo add tauri-plugin-clipboard # in src-tauri folder
npm i tauri-plugin-clipboard-api
Crate: https://crates.io/crates/tauri-plugin-clipboard
cargo add tauri-plugin-clipboard
to add the package.
Or add the following to your Cargo.toml
for the latest unpublished version (not recommanded).
tauri-plugin-clipboard = { git = "https://github.com/CrossCopy/tauri-plugin-clipboard" }
You can also add a tag to github url.
# for tag v0.6.5, this may not be the latest version, check the tag on github
tauri-plugin-clipboard = { git = "https://github.com/CrossCopy/tauri-plugin-clipboard", tag = "v0.6.6" }
NPM Package: https://www.npmjs.com/package/tauri-plugin-clipboard-api
Run the following to install JavaScript/TypeScript API package.
npm i tauri-plugin-clipboard-api
# or this for latest unpublished version (not recommended)
npm i https://github.com/CrossCopy/tauri-plugin-clipboard
# or this for tag, e.g. v0.6.5 (this may not be the latest version, check the tag on github)
npm i https://github.com/CrossCopy/tauri-plugin-clipboard#v0.6.6
Since Tauri V2 is still in beta. This plugin will still default to Tauri V2. If you are using this with Tauri v2, you can use branch v2
.
# In Cargo.toml
tauri-plugin-clipboard = { git = "https://github.com/CrossCopy/tauri-plugin-clipboard", branch = "v2" }
# Install npm package
npm i tauri-plugin-clipboard-api#v2 --save
In main.rs
, add the following to your tauri::Builder
:
tauri::Builder::default()
.plugin(tauri_plugin_clipboard::init()) // add this line
.run(tauri::generate_context!())
.expect("failed to run app");
Read more in the official doc about how to use.
The best way to learn this plugin is to read the source code of the example.
The example is very detailed.
npm run build
cd examples/demo
npm i
npm run tauri dev
# there are a few buttons you can click to test the clipboard plugin
See +page.svelte for an example of how to use the plugin in JS/TS.
It works the same with other frontend frameworks like Vue, React, etc.
import clipboard from "tauri-plugin-clipboard-api";
await clipboard.readText();
await clipboard.writeText("huakun zui shuai");
clipboard
.readImageBase64()
.then((base64Img) => {
imageStr = `data:image/png;base64, ${base64Img}`;
})
.catch((err) => {
alert(err);
});
await clipboard.writeImageBase64(sample_base64_image);
const files: string[] = await readFiles();
clipboard.readHtml().then((t: string) => {
// todo
});
ClipboardManager
contains the state state as well as the API functions.
use tauri::Manager;
use tauri_plugin_clipboard::ManagerExt;
fn main() {
tauri::Builder::default()
.plugin(tauri_plugin_clipboard::init())
.setup(|app| {
let handle = app.handle();
let clipboard = handle.state::<tauri_plugin_clipboard::Clipboard>();
clipboard.write_text("huakun zui shuai".to_string()).unwrap();
Ok(())
})
.build(tauri::generate_context!())
.expect("failed to run app");
}
We use Tauri's event system. Start a listener with Tauri's listen()
function to start listening for event, and call listenImage()
and listenText()
to listen for clipboard update. When clipboard is updated, event will be emitted.
The following example is in svelte.
Read the full source code in examples/demo/src/lib/components/listener.svelte.
import type { UnlistenFn } from "@tauri-apps/api/event";
import { onDestroy, onMount } from "svelte";
import {
onClipboardUpdate,
onImageUpdate,
onTextUpdate,
onHTMLUpdate,
onRTFUpdate,
onFilesUpdate,
startListening,
listenToMonitorStatusUpdate,
isMonitorRunning,
hasHTML,
hasImage,
hasText,
hasRTF,
hasFiles,
} from "tauri-plugin-clipboard-api";
let text = "";
let files: string[] = [];
let base64Image = "";
let htmlMonitorContent = "";
let monitorRunning = false;
let rtf = "";
let unlistenTextUpdate: UnlistenFn;
let unlistenImageUpdate: UnlistenFn;
let unlistenHtmlUpdate: UnlistenFn;
let unlistenRTF: UnlistenFn;
let unlistenClipboard: () => Promise<void>;
let unlistenFiles: UnlistenFn;
const has = {
hasHTML: false,
hasImage: false,
hasText: false,
hasRTF: false,
hasFiles: false,
};
onMount(async () => {
unlistenTextUpdate = await onTextUpdate((newText) => {
text = newText;
});
unlistenHtmlUpdate = await onHTMLUpdate((newHtml) => {
htmlMonitorContent = newHtml;
});
unlistenImageUpdate = await onImageUpdate((b64Str) => {
base64Image = b64Str;
});
unlistenFiles = await onFilesUpdate((newFiles) => {
files = newFiles;
});
unlistenRTF = await onRTFUpdate((newRTF) => {
rtf = newRTF;
});
unlistenClipboard = await startListening();
onClipboardUpdate(async () => {
has.hasHTML = await hasHTML();
has.hasImage = await hasImage();
has.hasText = await hasText();
has.hasRTF = await hasRTF();
has.hasFiles = await hasFiles();
console.log("plugin:clipboard://clipboard-monitor/update event received");
});
// setInterval(async () => {
// console.log("Running:", await isMonitorRunning());
// }, 1000);
});
listenToMonitorStatusUpdate((running) => {
monitorRunning = running;
});
onDestroy(() => {
if (unlistenTextUpdate) unlistenTextUpdate();
if (unlistenImageUpdate) unlistenImageUpdate();
if (unlistenHtmlUpdate) unlistenHtmlUpdate();
if (unlistenFiles) unlistenFiles();
if (unlistenClipboard) unlistenClipboard();
});
Clipboard Files has the following APIs, check the source code for more details (./webview-src/api.ts).
writeFilesURIs
files://
. Otherwise the code will throw an error. See the docstring in the source code for more details (./src/lib.rs).readFiles
readFilesURIs
Difference between URI and no-URI is that URI starts with files://
on Linux and MacOS. On Windows readFiles
and readFilesURIs
have no difference.
You don't really need to read this section if you are just using the plugin.
The logic of tauri's listen API is encapsulated in onTextUpdate
, onFilesUpdate
, startListening
.
You can also listen to the events directly using Tauri's listen()
function.
import {
TEXT_CHANGED,
FILES_CHANGED,
IMAGE_CHANGED,
} from "tauri-plugin-clipboard-api";
await listen(TEXT_CHANGED, (event) => {
const text = event.payload.value;
});
The listener startListening
function contains two parts:
start_monitor
command)listenToClipboard
function.
plugin:clipboard://clipboard-monitor/update
) when clipboard is updated without the clipboard content because we don't always need the content.listenToClipboard
detects the data type and emit new events.onTextUpdate
, onFilesUpdate
, startListening
listen to these events.
plugin:clipboard://text-changed
plugin:clipboard://files-changed
plugin:clipboard://image-changed
plugin:clipboard://html-changed
plugin:clipboard://rtf-changed
The returned unlisten function from startListening
also does two things:
stop_monitor
command to Tauri core.listenToClipboard
.For more details read the source code from ./webview-src/api.ts.
The base64 image string can be converted to Uint8Array
and written to file system using tauri's fs API. (We also provide a readImageBinary
function to read image as binary data (Uint8Array
is one of the available return type).
import { writeBinaryFile, BaseDirectory } from "@tauri-apps/api/fs";
writeBinaryFile(
"tmp/avatar.png",
new Uint8Array(
atob(base64Img)
.split("")
.map((char) => char.charCodeAt(0))
),
{ dir: BaseDirectory.Cache }
);
