    Airbrake-JS

    Build Status CDNJS

    This is the JavaScript notifier for capturing errors in web browsers and reporting them to Airbrake.

    Installation

    Using yarn:

    yarn add airbrake-js
    yarn add cross-fetch # add cross-fetch as peerDependency 

    or Using npm:

    npm install airbrake-js
    npm install cross-fetch # add cross-fetch as peerDependency 

    Setup

    Example configurations can be found in examples, including:

    The notifier is built using umd and therefore can be imported with AMD, CommonJS2 or as property in root.

    If you prefer not to host the library yourself, airbrake-js is available on the excellent cdnjs.

    If you're using Webpack in browser context you might need to mark certain Node.js packages as external dependencies to decrease bundle size.

    Basic Usage

    First you need to initialize the notifier with the project id and API key taken from Airbrake.io:

    var airbrake = new airbrakeJs.Client({
      projectId: 1,
      projectKey: 'REPLACE_ME',
      environment: 'production',
    });

    Or if you are using browserify/webpack/etc:

    var AirbrakeClient = require('airbrake-js');
    var airbrake = new AirbrakeClient({...});

    Then you can send a textual message to Airbrake:

    var promise = airbrake.notify(`user id=${user_id} not found`);
    promise.then(function(notice) {
      if (notice.id) {
        console.log('notice id', notice.id);
      } else {
        console.log('notify failed', notice.error);
      }
    });

    Or report catched errors directly:

    try {
      // This will throw if the document has no head tag
      document.head.insertBefore(document.createElement('style'));
    } catch(err) {
      airbrake.notify(err);
      throw err;
    }

    Alternatively, you can wrap any code which may throw errors using the client's wrap method:

    var startApp = function() {
      // This will throw if the document has no head tag.
      document.head.insertBefore(document.createElement('style'));
    }
    startApp = airbrake.wrap(startApp);
     
    // Any exceptions thrown in startApp will be reported to Airbrake.
    startApp();

    or use call shortcut:

    var startApp = function() {
      // This will throw if the document has no head tag.
      document.head.insertBefore(document.createElement('style'));
    }
     
    airbrake.call(startApp);

    Advanced Usage

    Notice Annotations

    It's possible to annotate error notices with all sorts of useful information at the time they're captured by supplying it in the object being reported.

    try {
      startApp();
    } catch (err) {
      airbrake.notify({
        error:       err,
        context:     { component: 'bootstrap' },
        environment: { env1: 'value' },
        params:      { param1: 'value' },
        session:     { session1: 'value' },
      });
      throw err;
    }

    Severity

    Severity allows categorizing how severe an error is. By default, it's set to error. To redefine severity, simply overwrite context/severity of a notice object. For example:

    airbrake.notify({
      error: err,
      context: { severity: 'warning' }
    });

    Filtering errors

    There may be some errors thrown in your application that you're not interested in sending to Airbrake, such as errors thrown by 3rd-party libraries, or by browser extensions run by your users.

    The Airbrake notifier makes it simple to ignore this chaff while still processing legitimate errors. Add filters to the notifier by providing filter functions to addFilter.

    addFilter accepts the entire error notice to be sent to Airbrake, and provides access to the context, environment, params, and session values submitted with the notice, as well as the single-element errors array with its backtrace element and associated backtrace lines.

    The return value of the filter function determines whether or not the error notice will be submitted.

    • If a null value is returned, the notice is ignored.
    • Otherwise, the returned notice will be submitted.

    An error notice must pass all provided filters to be submitted.

    In the following example all errors triggered by admins will be ignored:

    airbrake.addFilter(function(notice) {
      if (notice.params.admin) {
        // Ignore errors from admin sessions.
        return null;
      }
      return notice;
    });

    Filters can be also used to modify notice payload, e.g. to set the environment and application version:

    airbrake.addFilter(function(notice) {
      notice.context.environment = 'production';
      notice.context.version = '1.2.3';
      return notice;
    });

    Filtering keys

    With keysBlacklist option you can specify list of keys containing sensitive information that must be filtered out, e.g.:

    var airbrake = new AirbrakeClient({
        ...
        keysBlacklist: [
          'password', // exact match
          /secret/, // regexp match
        ],
    });

    Source maps

    Airbrake supports using private and public source maps. Check out our docs for more info:

    Instrumentation

    airbrake-js automatically instruments console.log function calls in order to collect logs and send them with first error. You can disable that behavior using instrumentation option:

    var airbrake = new airbrakeJs.Client({
      ...
      instrumentation: {
        console: false,
      },
    });

    Node.js request and proxy

    In order to configure request HTTP client you can pass request option which accepts request wrapper:

    var airbrake = new AirbrakeClient({
      ...
      request: request.defaults({'proxy':'http://localproxy.com'})
    });

    Integration

    window.onerror

    airbrake-js automatically setups window.onerror handler when script is loaded. It also makes sure to call old error handler if there are any. Errors reported by window.onerror can be ignored using ignoreWindowError option:

    var airbrake = new airbrakeJs.Client({ignoreWindowError: true});

    What does "Script error" mean?
