PageSense Node.js SDK — Overview
What is FullStack A/B Testing?
Most A/B testing happens in the UI — swap a button color, test a headline. FullStack A/B testing goes deeper. It lets you run experiments directly in your application code: backend logic, APIs, pricing models, algorithms, recommendation engines, feature flags — all testable.
In a FullStack A/B test:
- Users are bucketed deterministically into experiment variations.
- Each variation implements a different behaviour or feature.
- Goal tracking tells you which variation actually performs better.
Common use cases:
- Testing different API behaviours
- Comparing pricing models
- Optimising algorithms and recommendation engines
- Running backend performance experiments
How the Node.js SDK fits in
The PageSense Node.js SDK is a lightweight wrapper over the PageSense REST APIs. Drop it into any Node.js backend, and your application can run experiments, serve variations, and track conversions — entirely server-side, no client integration needed.
It handles all communication with PageSense internally. You write application logic; the SDK handles the experimentation layer.
What you get:
- FullStack A/B testing with minimal setup.
- Automatic sync of project settings and experiment configurations.
- Real-time capture of user interactions and conversion events.
- User attribute storage for audience targeting and report segmentation.
At runtime, the SDK:
- Fetches all active experiments from your PageSense project.
- Determines the right variation for each user.
- Tracks goal completions and experiment events.
- Sends metrics and activity data back to PageSense for reporting.
