# Sentry for Google Cloud Functions (JavaScript)

This guide is for `@sentry/google-cloud-serverless` version `8.0.0` and up.

##### Using Cloud Functions for Firebase?

If you're using [Cloud Functions for Firebase](https://firebase.google.com/docs/functions), see our dedicated [Firebase guide](https://docs.sentry.io/platforms/javascript/guides/firebase.md) for a simpler setup using `@sentry/node`.

## [Prerequisites](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#prerequisites)

You need:

* A Sentry [account](https://sentry.io/signup/) and [project](https://docs.sentry.io/product/projects.md)
* Your application up and running

## [Install](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#install)

### [Install the Sentry SDK](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#install-the-sentry-sdk)

Run the command for your preferred package manager to add the Sentry SDK to your application:

```bash
npm install @sentry/google-cloud-serverless --save
```

*Other available variations of the above snippet: yarn, pnpm*

```bash
npm install @sentry/google-cloud-serverless @sentry/profiling-node --save
```

*Other available variations of the above snippet: yarn, pnpm*

## [Configure](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#configure)

**Error Monitoring** starts working as soon as you call `Sentry.init()`. **Logs** and **Application Metrics** need no extra configuration, and you'll learn how to send them in steps [#3](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#send-logs) and [#4](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#send-application-metrics-). This guide also enables **Tracing** and **Profiling**.

Want to learn more about these features?

* [**Issues**](https://docs.sentry.io/product/issues.md) (always enabled): Sentry's core error monitoring product that automatically reports errors, uncaught exceptions, and crashes. If you have something that looks like an exception, Sentry can capture it.
* [**Tracing**](https://docs.sentry.io/product/tracing.md): Track software performance while seeing the impact of errors across multiple systems. For example, distributed tracing allows you to follow a request from the frontend to the backend and back.
* [**Profiling**](https://docs.sentry.io/product/profiling.md): Gain deeper insight than traditional tracing without custom instrumentation, letting you discover slow-to-execute or resource-intensive functions in your app.
* [**Logs**](https://docs.sentry.io/product/logs.md): Centralize and analyze your application logs to correlate them with errors and performance issues. Search, filter, and visualize log data to understand what's happening in your applications.
* [**Application Metrics**](https://docs.sentry.io/product/metrics.md) (always enabled): Track and analyze custom application metrics, such as response times and database query durations, to understand trends and patterns in your application's performance and behavior over time.

Make sure to initialize Sentry at the top of your function code and wrap each function with the appropriate helper.

The snippet also turns on:

* Tracing: via [`tracesSampleRate`](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/options.md#tracesSampleRate)
* Profiling: via [`profileSessionSampleRate`](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/options.md#profileSessionSampleRate), [`profileLifecycle`](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/options.md#profileLifecycle), and the profiling integration

Don't need a feature? Remove its integration and options from the snippet.

Select the tab that matches the kind of function you're using (HTTP, Background, or CloudEvent):

**Http functions**

```javascript
const Sentry = require("@sentry/google-cloud-serverless");
const { nodeProfilingIntegration } = require("@sentry/profiling-node");

Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  integrations: [
    // enables Profiling
    nodeProfilingIntegration(),
  ],
  // Enables Tracing.
  // Set to 1.0 to capture 100% of spans for tracing.
  // We recommend reducing this value in production.
  tracesSampleRate: 1.0,
  // Enables Profiling for every session.
  profileSessionSampleRate: 1.0,
  profileLifecycle: "trace",
});

exports.helloHttp = Sentry.wrapHttpFunction((req, res) => {
  throw new Error("oh, hello there!");
});
```

**Background functions**

```javascript
const Sentry = require("@sentry/google-cloud-serverless");
const { nodeProfilingIntegration } = require("@sentry/profiling-node");

Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  integrations: [
    // enables Profiling
    nodeProfilingIntegration(),
  ],
  // Enables Tracing.
  // Set to 1.0 to capture 100% of spans for tracing.
  // We recommend reducing this value in production.
  tracesSampleRate: 1.0,
  // Enables Profiling for every session.
  profileSessionSampleRate: 1.0,
  profileLifecycle: "trace",
});

exports.helloEvents = Sentry.wrapEventFunction(
  (data, context, callback) => {
    throw new Error("oh, hello there!");
  },
);
```

**CloudEvent functions**

```javascript
const Sentry = require("@sentry/google-cloud-serverless");
const { nodeProfilingIntegration } = require("@sentry/profiling-node");

Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  integrations: [
    // enables Profiling
    nodeProfilingIntegration(),
  ],
  // Enables Tracing.
  // Set to 1.0 to capture 100% of spans for tracing.
  // We recommend reducing this value in production.
  tracesSampleRate: 1.0,
  // Enables Profiling for every session.
  profileSessionSampleRate: 1.0,
  profileLifecycle: "trace",
});

exports.helloEvents = Sentry.wrapCloudEventFunction(
  (context, callback) => {
    throw new Error("oh, hello there!");
  },
);
```

### [Add Readable Stack Traces With Source Maps](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#add-readable-stack-traces-with-source-maps)

The stack traces in your Sentry errors probably won't look like your actual code without unminifying them. To fix this, upload your source maps to Sentry. The easiest way to do this is by using the Sentry Wizard.

Alternatively, take a look at our [Uploading Source Maps](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/sourcemaps/uploading.md) documentation.

```bash
npx @sentry/wizard@latest -i sourcemaps
```

### [Control the Data You Send to Sentry](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#control-the-data-you-send-to-sentry)

By default, the SDK sends user identity data (IP address, ID, and similar) and other data like HTTP bodies and URL query parameters. This will give you rich debugging context.

The SDK always filters sensitive values whose keys match a built-in denylist, such as `auth` or `password`, and sends `[Filtered]` instead.

To send less data, turn off the categories you don't need in the `dataCollection` option. For the full list of categories and their defaults, [see the `dataCollection` options](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/options.md#dataCollection).

```javascript
Sentry.init({
  dsn: "https://<key>@o<orgId>.ingest.sentry.io/<projectId>",
  dataCollection: {
    userInfo: false,
    // other categories
  },
});
```

## [Send Logs](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#send-logs)

Use `Sentry.logger` to send logs at different levels, such as `info`, `warn`, or `error`. You can pass any attributes you want and search or filter by them later. See [Set Up Logs](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/logs.md) for all available logging methods and the syntax for formatting messages.

```javascript
Sentry.logger.info("User example action completed");

Sentry.logger.warn("Slow operation detected", {
  operation: "data_fetch",
  duration: 3500,
});

Sentry.logger.error("Validation failed", {
  form_field: "email",
  reason: "Invalid email",
});
```

If you're already logging with another library, use an integration to capture those logs as Sentry Logs automatically:

* [`consoleLoggingIntegration`](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/logs.md#console-integration) for `console` calls
* [Consola](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/logs.md#console-integration)
* [Pino](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/integrations/pino.md)

## [Send Application Metrics NEW](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#send-application-metrics-)

Use `Sentry.metrics` to send counters, gauges, and distributions from your app to Sentry. You can pass any attributes you want and search or filter by them later. See [Set Up Metrics](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/metrics.md) for all available metric types and configuration options.

```javascript
Sentry.metrics.count("checkout.failed", 1);

Sentry.metrics.gauge("time_since_refresh", 4, { unit: "hour" });

Sentry.metrics.distribution("api_latency", 187, {
  unit: "millisecond",
  attributes: { endpoint: "/api/orders" },
});
```

On Node.js, [`nodeRuntimeMetricsIntegration`](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/integrations/noderuntimemetrics.md) also collects runtime health metrics automatically.

## [Verify Your Setup](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#verify-your-setup)

Let's test your setup and confirm that Sentry is working correctly and sending data to your Sentry project.

Add an intentional error to a wrapped function, then invoke it to verify that Sentry captures the error:

```javascript
exports.helloHttp = Sentry.wrapHttpFunction((req, res) => {
  throw new Error("Sentry Test Error");
});
```

### [View Captured Data in Sentry](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#view-captured-data-in-sentry)

Now, head over to your project on [Sentry.io](https://sentry.io/) to view the collected data (it takes a couple of moments for the data to appear).

Need help locating captured data in your Sentry project?

* Open the [**Issues**](https://sentry.io/orgredirect/organizations/:orgslug/issues/) page and select an error from the issues list to view the full details and context of this error. For more details, see the [Issue Details documentation](https://docs.sentry.io/product/issues/issue-details.md).
* Open the [**Traces**](https://sentry.io/orgredirect/organizations/:orgslug/explore/traces/) page and select a trace to reveal more information about each span, its duration, and any errors. For an interactive UI walkthrough, click [here](https://docs.sentry.io/product/sentry-basics/getting-started-tutorial/generate-first-error.md#ui-walkthrough).
* Open the [**Profiles**](https://sentry.io/orgredirect/organizations/:orgslug/profiling/) page to see your slowest functions and an aggregate flame graph of your most frequent code paths. If tracing is enabled, select a transaction to see the flame graph for that part of your app. For more information, click [here](https://docs.sentry.io/product/profiling/profile-details.md).
* Open the [**Logs**](https://sentry.io/orgredirect/organizations/:orgslug/explore/logs/) page and filter by service, environment, or search keywords to view log entries from your application. For an interactive UI walkthrough, click [here](https://docs.sentry.io/product/logs.md#overview).
* Open the [**Application Metrics**](https://sentry.io/orgredirect/organizations/:orgslug/explore/metrics) page to view and analyze your metrics. For more details, see this [interactive walkthrough](https://docs.sentry.io/product/metrics.md#overview).

## [Next Steps](https://docs.sentry.io/platforms/javascript/guides/gcp-functions.md#next-steps)
