Anonymous: is there an offline mode, let’s say when running integration tests (during which you don’t really want to ping Statsig but still need to get a flag value)?

Statbot: Yes, you can use the localMode option to run the SDK in offline mode. When localMode is set to true, the SDK will not make any network requests and will only return default values or values set via local overrides. This is ideal for integration tests or dummy environments. Here’s an example of how to enable localMode and set overrides:

const statsig = require('statsig-node');
statsig.initialize('secret-key', { localMode: true });
statsig.overrideGate('example_gate', true);
const gateValue = statsig.checkGate({ userID: 'test_user' }, 'example_gate');
console.log(gateValue); // true

For more details, you can refer to the documentation on source.

Statbot: Yes, there is an offline mode called localMode. When localMode is set to true, the SDK will not make any network requests and will only return default values. This is useful for integration tests or dummy environments. You can also use the overrideGate and overrideConfig APIs to set specific values for gates and configs during testing. Here is an example for Node.js:

const statsig = require('statsig-node');
statsig.initialize('secret-key', { localMode: true });
statsig.overrideGate('example_gate', true);
statsig.overrideConfig('example_config', { key: 'value' });
