const { ExperimentClient } = require('@amplitude/experiment-core');
const client = new ExperimentClient('YOUR_API_KEY');
Fetch Variants
Fetches the variants for a given user. This is useful for determining which variant of an experiment a user should see.
client.fetch({ user_id: 'user123' }).then(variants => {
console.log(variants);
});
Track Exposure
Tracks the exposure of a user to a specific variant. This is important for measuring the impact of different variants in your experiments.
client.track({ user_id: 'user123', variant: 'variantA' });
