Usage

Initiate

Call Bugcatch as-soon-as-possible within your code.

bugcatch.init({
    base_url: "https://example.com/bugcatch",

    // Optional
    release: "2.1.0",
    //       ^^^^^^^ --> process.env.npm_package_version
    disableWebVitals: false,
    disableError: false,
    disableUnhandledRejection: false,
    requiredVitals: [
        // Uses perfume.js for web vitals,
        // You have the option to add/remove unwanted vitals here
        "cls",
        "dataConsumption",
        "fcp",
        "fid",
        "fp",
        "lcp",
        "navigationTiming",
        "navigatorInformation",
        "networkInformation",
        "storageEstimate",
        "tbt",
    ],
});

Thats it! - sit back and try not to panic as the bugs roll in!

You can also use the recordEvent method to record custom events with data attached (the data can be of any type and size).

bugcatch.recordEvent(name, data, userOptions);

// Crude Example,
// An event for users which stay on the page longer than 10 minutes
setTimeout(function () {
    bugcatch.recordEvent(
        "loyal_viewer",
        { timeOnPage: "10 minutes" },
        {
            base_url: "https://example.com/bugcatch",
            release: "2.1.0",
        }
    );
}, 1000 * 60 * 10);

How It Works

Catching Errors

bugcatch makes use of the error and unhandledrejection event listeners to catch each error and its details.

// Listen to uncaught errors
window.addEventListener("error", onError);

// Listen to uncaught promises rejections
window.addEventListener("unhandledrejection", onError);

Web Vitals

bugcatch also gathers web vitals data. This can play a very important role when squashing bugs, but also general optimisation.
