Use crates.io and npm (easiest, and requires you to trust that our publishing pipeline worked) 12 | 2. Pull sources directly from Github using git tags / revision hashes (most secure) 13 | 3. Git submodule install this repo in your tauri project and then use file protocol to ingest the source (most secure, but inconvenient to use) 14 | 15 | Install the Core plugin by adding the following to your `Cargo.toml` file: 16 | 17 | `src-tauri/Cargo.toml` 18 | 19 | ```toml 20 | [dependencies] 21 | tauri-plugin-websocket = { git = "https://github.com/tauri-apps/plugins-workspace", branch = "v1" } 22 | ``` 23 | 24 | You can install the JavaScript Guest bindings using your preferred JavaScript package manager: 25 | 26 | > Note: Since most JavaScript package managers are unable to install packages from git monorepos we provide read-only mirrors of each plugin. This makes installation option 2 more ergonomic to use. 27 | 28 | ```sh 29 | pnpm add https://github.com/tauri-apps/tauri-plugin-websocket#v1 30 | # or 31 | npm add https://github.com/tauri-apps/tauri-plugin-websocket#v1 32 | # or 33 | yarn add https://github.com/tauri-apps/tauri-plugin-websocket#v1 34 | ``` 35 | 36 | ## Usage 37 | 38 | First you need to register the core plugin with Tauri: 39 | 40 | `src-tauri/src/main.rs` 41 | 42 | ```rust 43 | fn main() { 44 | tauri::Builder::default() 45 | .plugin(tauri_plugin_websocket::init()) 46 | .run(tauri::generate_context!()) 47 | .expect("error while running tauri application"); 48 | } 49 | ``` 50 | 51 | Afterwards all the plugin's APIs are available through the JavaScript guest bindings: 52 | 53 | ```javascript 54 | import WebSocket from "tauri-plugin-websocket-api"; 55 | 56 | const ws = await WebSocket.connect("wss://example.com"); 57 | 58 | await ws.send("Hello World"); 59 | 60 | await ws.disconnect(); 61 | ``` 62 | 63 | ## Contributing 64 | 65 | PRs accepted.
