Note: This is the v1 version of the notifier. See the migration guide for instructions on how to upgrade your code to use the latest version of the Rollbar javascript notifier.
Copy-paste the following code into the <head> of every page you want to monitor. It should be as high as possible, before any other <script> tags.
Be sure to replace POST_CLIENT_ITEM_ACCESS_TOKEN with your project's post_client_item access token, which you can find in the Rollbar.com interface.
<script>
var _rollbarConfig = {
accessToken: "POST_CLIENT_ITEM_ACCESS_TOKEN",
captureUncaught: true,
payload: {
environment: "production"
}
};

</script>If you're running Rollbar on an environment besides production, change the environment value to something else (e.g. "staging"). See below for more configuration options.
- Navigate your browser to a page that has the above code installed
- Type the following code into the console and press enter:
window.onerror("TestRollbarError: testing window.onerror", window.location.href)
This simulates an uncaught error. It should appear in the Rollbar dashboard within a few seconds.
In addition to catching top-level errors, you can send caught errors or custom log messages. All of the following methods are fully-asynchronous and safe to call anywhere in your code after the <script> tag above.
// Caught errors
try {
doSomething();
} catch (e) {
Rollbar.error("Something went wrong", e);
}
// Arbitrary log messages. 'critical' is most severe; 'debug' is least.
Rollbar.critical("Connection error from remote Payments API");
Rollbar.error("Some unexpected condition");
Rollbar.warning("Connection error from Twitter API");
Rollbar.info("User opened the purchase dialog");
Rollbar.debug("Purchase dialog finished rendering");
// Can include custom data with any of the above.
// It will appear as `custom.postId` in the Occurrences tab
Rollbar.info("Post published", {postId: 123});
// Callback functions
Rollbar.error(e, function(err, data) {
if (err) {
console.log("Error while reporting error to Rollbar: ", e);
} else {
console.log("Error successfully reported to Rollbar. UUID:", data.uuid);
}
});To set configuration options at runtime, use Rollbar.configure:
// Set the person data to be sent with all errors for this notifier.
Rollbar.configure({
payload: {
person: {
id: 456,
username: "foo",
email: "foo@example.com"
}
}
});(Advanced) For fine-grained control of the payload sent to the Rollbar API, use Rollbar.scope:
Rollbar.scope({fingerprint: "custom fingerprint to override grouping algorithm"}).error(err);If you minify your JavaScript in production, you'll want to configure source maps so you get meaningful stack traces. See the source maps guide for instructions.
