react-split-testing

A/B testing, also called split testing, is an experiment where two (or more) variants of a webpage are shown to users at random, and is used as a means of determining which variant leads to a better performance. Once a variant wins, it is then shown to all users.

Wrap components in <Variant /> and nest in <Experiment />. A variant is chosen randomly and saved to local storage.

<Experiment name="My Example">
  <Variant name="A">
    <div>Version A</div>
  </Variant>
  <Variant name="B">
    <div>Version B</div>
  </Variant>
</Experiment>

Server Rendering

A <Experiment /> with a userIdentifier property will choose a consistent <Variant /> suitable for server side rendering.

Example

import { Experiment, Variant } from 'react-split-testing'

class App extends Component {
  render() {
    return (
      <Experiment name="My experiment" userIdentifier={this.props.userIdentifier}>
        <Variant name="A">
          <div>Section A</div>
        </Variant>
        <Variant name="B">
          <div>Section B</div>
        </Variant>
      </Experiment>
    )
  }
}
