Simple node.js script to achieve a bridge between rust and node.js. Use with the cargo crate node_bridge.
npm install rustlang-bridgeSimple node.js script to achieve a bridge between rust and node.js. Use with the cargo crate node_bridge.
Only 1 bridge can be initialized per rust program. But node.js can have many bridges.
``bash`
$ npm install rustlang-bridge
Rust installation:
Add the following line to your Cargo.toml under [dependencies]toml`
node_bridge = "1.0.2"
`rust
use node_bridge::NodeBridge;
#[tokio::main]
async fn main() {
let bridge = NodeBridge::new();
bridge.register("addition", add, None);
bridge.register_async("find_longer", find_longer, Some("Variable to pass to the function"));
assert_eq!(bridge.receive("channel_a").await.unwrap(), "Sent this from node!");
bridge.send("channel_foo", "bar").ok();
bridge.wait_until_closes().await;
}
fn add(params: Vec
params[0] + params[1]
}
async fn find_longer(params: Vec
assert_eq!(pass_data, Some("Variable to pass to the function"));
if params[0].len() > params[1].len() {
return params[0].to_string();
}
params[1].to_string()
}
`
Handling in node.js:
`javascript``
import RustBridge from "rustlang-bridge";
const bridge = new RustBridge("/path/to/rust_executable");
await new Promise(resolve => setTimeout(resolve, 500)); // wait for the functions to initialize
console.log(await bridge.addition(10, 20)); // "30"
console.log(await bridge.find_longer("foo", "longer_foo")); // "longer_foo"
bridge.on("channel_foo", data => {
console.log(data); // "bar"
});
bridge.send("channel_a", "Sent this from node!");
