Using highlight.io with actix-web
Learn how to set up highlight.io without a framework.
1
Add `tracingOrigins` to your client Highlight snippet.
This backend SDK requires one of the Highlight frontend SDKs to be installed, so please make sure you've followed the fullstack mapping guide first.
H.init("<YOUR_PROJECT_ID>", {
tracingOrigins: ['localhost', 'example.myapp.com/backend'],
networkRecording: {
enabled: true,
recordHeadersAndBody: true,
},
});
2
Install the Highlight Rust actix SDK.
Add Highlight to your Config.toml.
[dependencies]
highlightio-actix = "1"3
Initialize the Highlight Rust SDK and actix Middleware.
highlightio_actix::highlight::Highlight::init initializes the SDK, and adding the highlightio_actix::HighlightActix middleware will start tracing actix.
use actix_web::{App, Error, HttpServer};
use highlightio_actix::{highlight::{Highlight, HighlightConfig}, HighlightActix};
// ...your services...
#[actix_web::main]
async fn main() -> Result<(), Error> {
let h = Highlight::init(HighlightConfig {
project_id: "<YOUR_PROJECT_ID>".to_string(),
service_name: "my-rust-app".to_string(),
service_version: "git-sha".to_string(),
..Default::default()
}).expect("Failed to initialize Highlight.io");
let _h = h.clone();
HttpServer::new(move || {
App::new()
.wrap(HighlightActix::new(&_h))
// ...
})
.bind("127.0.0.1:8080")?
.run()
.await?;
h.shutdown();
Ok(())
}4
Verify your errors are being recorded.
Now that you've set everything up, you can verify that the backend error handling works by throwing an error in a service. Visit the highlight errors page and check that backend errors are coming in.
// ...
#[get("/error")]
async fn error() -> Result<impl Responder, std::io::Error> {
Err(std::io::Error::new(
std::io::ErrorKind::Other,
"Test error"
))?;
Ok(format!("You shouldn't be able to see this."))
}
// ...
#[actix_web::main]
async fn main() -> Result<(), Error> {
// ...
HttpServer::new(move || {
App::new()
.wrap(HighlightActix::new(&h))
.service(error) // add this
})
// ...
}5
Set up logging.
Start sending logs to Highlight! Follow the logging setup guide to get started.
