Get started with the Statsig SDK - Statsig Documentation

1

Install Statsig packages

npm install @statsig/react-bindings

2

Wrap child components

Next, update your app’s default function (Usually App.tsx or Layout.tsx) so that the StatsigProvider wraps around all child components.

import { StatsigProvider } from "@statsig/react-bindings"; 

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <StatsigProvider
      sdkKey={"client-MY-STATSIG-CLIENT-KEY"}
      user={{ userID: "quickstart-user" }}
      loadingComponent={<div>Loading...</div>}>
      {children}
    </StatsigProvider>
  );
}

This example assumes you’re using client-side React, if you’re Server-Side Rendering, you’d be better served by our Next.js docs.

3

Add client key

Create a client API key in the Statsig console Settings. Copy and paste it to replace <REPLACE_WITH_YOUR_CLIENT_KEY> in the code snippet from the previous step.

4

Basic Usage

Check a Gate
Get an Experiment Value
Log an Event

First, create a gate on the Feature Gates page in console, then check it in-code:

const { client } = useStatsigClient();
return (
  <div>Gate is {client.checkGate('check_user') ? 'passing' : 'failing'}.</div>
);

First, create an Experiment on the Experiments page in console

const { client } = useStatsigClient();
const experiment = client.getExperiment('my_experiment_name');

return (
  <div>Headline Parameter: {experiment.get('my_experiment_parameter_name', 'fallback_value')}.</div>
);

You can use Events to power metrics in your experiment or gates. Events don’t need to be set up in console first, just add to your code:

const { client } = useStatsigClient();
return <button onClick={() => client.logEvent("button_click")}>Click Me</button>

Congratulations! You’ve successfully set up the Statsig SDK in React. Continue on to the tutorials, or jump in to the full Next.js or React SDK libraries.

1

Paste the code snippet

In the <head> section of your website, paste the following code snippet:

<script src="https://cdn.jsdelivr.net/npm/@statsig/js-client@3/build/statsig-js-client+session-replay+web-analytics.min.js?apikey=<REPLACE_WITH_YOUR_CLIENT_KEY>"></script>

2

Add client key

Create a client API key in the Statsig console Settings. Copy and paste it to replace <REPLACE_WITH_YOUR_CLIENT_KEY> in the code snippet from the previous step.

3

Basic usage

Check a Gate
Get an Experiment Value
Log an Event

First, create a gate on the Feature Gates page in console, then check it in-code:

window.Statsig.instance().checkGate("my_feature_gate_name");

You’ll want to wait for the SDK to initialize before checking a gate to ensure it has fresh values, one way to accomplish this is waiting for the “values_updated” event.

First, create an Experiment on the Experiments page in console

window.Statsig.instance().getExperiment("my_experiment_name").get('my_experiment_parameter_name');

You’ll want to wait for the SDK to initialize before getting an experiment to ensure it has fresh values, one way to accomplish this is waiting for the “values_updated” event.

You can use Events to power metrics in your experiment or gates. Events don’t need to be set up in console first, just add to your code:

window.Statsig.instance().logEvent("my_checkout_event_name", "event_value_item_1234", {"event_metadata": "my_metadata"})

Next steps

Congratulations! You’ve set up the Statsig JavaScript snippet. You can now start:

See the Javascript SDK reference for more info.

1

Install the Statsig package

pip install statsig-python-core

2

Initialize the Statsig SDK

from statsig_python_core import Statsig, StatsigOptions

options = StatsigOptions()
options.environment = "development"

statsig = Statsig("<REPLACE_WITH_YOUR_SERVER_SECRET_KEY>", options)
statsig.initialize().wait()

statsig.shutdown().wait()

3

Add server secret key

Create a server secret key in the Statsig console Settings. Copy and paste it to replace <REPLACE_WITH_YOUR_SERVER_SECRET_KEY> in the code snippet from the previous step.

4

Basic Usage

Check a Gate
Get an Experiment Value
Log an Event

First, create a gate on the Feature Gates page in console, then check it in-code:

user_object = StatsigUser(user_id="123", email="testuser@statsig.com") //add any number of other attributes
gate_value = statsig.check_gate(user_object, "my_feature_gate_name"):

First, create an Experiment on the Experiments page in console

user_object = StatsigUser(user_id="123", email="testuser@statsig.com"
my_experiment_object = statsig.get_experiment(user_object, "my_experiment_name")
my_experiment_parameter_value = my_experiment_object.get_string('my_experiment_parameter_name')

You can use Events to power metrics in your experiment or gates. Events don’t need to be set up in console first, just add to your code:

user_object = StatsigUser(user_id="123", email="testuser@statsig.com"

statsig.log_event(
  user=user_object,
  event_name="my_checkout_event_name",
  value="SKU_12345"
)

Congratulations! You’ve set up the Statsig SDK in Python. Continue on to our tutorials, or jump in to the full Python SDK Reference.

1

Install the Statsig package

npm i @statsig/statsig-node-core

2

// Basic initialization
const statsig = new Statsig("<REPLACE_WITH_YOUR_SERVER_SECRET_KEY>");
await statsig.initialize();

// or with StatsigOptions
const options: StatsigOptions = { environment: "staging" };

const statsigWithOptions = new Statsig("secret-key", options);
await statsigWithOptions.initialize();

3

Add server secret key

Create a server secret key in the Statsig console Settings. Copy and paste it to replace <REPLACE_WITH_YOUR_SERVER_SECRET_KEY> in the code snippet from the previous step.

4

Basic Usage

Check a Gate
Get an Experiment Value
Log an Event

First, create a gate on the Feature Gates page in console, then check it in-code:

const userObject = new StatsigUser({ userID: "123", email="testuser@statsig.com" });
const is_gate_enabled = statsig.checkGate(userObject, "my_feature_gate_name"):

First, create an Experiment on the Experiments page in console

const userObject = new StatsigUser({ userID: "123", email="testuser@statsig.com" });
const myExperimentObject = statsig.getExperiment(userObject, "my_experiment_name")
const myExperimentParameterValue = myExperimentObject.getValue('my_experiment_parameter_name')

You can use Events to power metrics in your experiment or gates. Events don’t need to be set up in console first, just add to your code:

userObject = StatsigUser(user_id="123", email="testuser@statsig.com"

statsig.logEvent(
  userObject,
  "my_checkout_event_name",
  "SKU_12345" //value for the event
);
