Implements a logger that can be used in web browsers.

Not required. Libraries should use the log crate instead.

It must be added along with log to the project dependencies:

[dependencies]
log = "0.4"
web_logger = "0.2"

web_logger must be initialized as early as possible in the project. After it's initialized, you can use the log macros to do actual logging.

#[macro_use]
extern crate log;
extern crate web_logger;

fn main() {
    web_logger::init();

    info!("starting up");

    // ...
}
