tracing-web

A [tracing] compatible subscriber layer for web platforms.

Documentation

Overview

tracing-web can be used in conjunction with the [tracing-subscriber] crate to quickly install a subscriber that emits messages to the dev-tools console, and events to the [Performance API]. An example configuration can look like

```rust use tracingweb::{MakeConsoleWriter, performancelayer}; use tracingsubscriber::fmt::format::Pretty; use tracingsubscriber::fmt::time::UtcTime; use tracing_subscriber::prelude::*;

fn main() { let fmtlayer = tracingsubscriber::fmt::layer() .withansi(false) // Only partially supported across browsers .withtimer(UtcTime::rfc3339()) // std::time is not available in browsers .withwriter(MakeConsoleWriter); // write events to the console let perflayer = performancelayer() .withdetailsfrom_fields(Pretty::default());

tracing_subscriber::registry()
    .with(fmt_layer)
    .with(perf_layer)
    .init(); // Install these as subscribers to tracing events

todo!("write your awesome application");

} ```
