ab-worker-prototype's Introduction

Client A/B testing

Client A/B testing refers to the method of performing experimentation related changes to a web application at runtime, typically within a browser. This method of experimentation is popular in the industry as it is easier to deploy, requires minimal to no engineering bandwidth for creating experiments and is accessible to non-engineering personnel as well.

This incubation's objective is to devise methods of conducting the same outcome with all its benefits offered, but without the performance penalties.

Goals

Standardize A/B transformation operations to a spec.
Enable application of experimentation changes at the Origin, an intermediary CDN/Edge/Proxy or the Browser.
Minimize or eliminate performance metrics degradation caused by application of changes in the browser through performant methods and through exploration of browser-native implementations.

ab-worker-prototype's Issues

[CF][NPM][SDK] Validate Transformations Passed to applyTransformations

Validate that the transformations passed into the applyTransformations method conform to specifications, specifically with regards to the arguments passed in (which vary depending on the Operation).

Decide whether or not to fail entirely if any are misconfigured, or just to ignore those transformations that are misconfigured.

Option to attach custom event handler for newly inserted element

After adding new DOM element, user might want to also attach custom event to the element - for example onClick() event.

Option to add new element Before and After selected DOM element

The proposed document allows new element to be added at the beginning of the selected DOM element (prepend) or at the end (append) as shown here

It is also necessary to be able to add new element Before or After selected DOM element.

[1, "h1", "after", "<h2>Subtitle</h2>"],
[1, "h1", "before", "<h5>Section Name</h5>"],

Option to relocate selected DOM element

User might want to move/rearrange existing DOM element as part of experiment.

There should be an option to select specific DOM element and point to a new location by selecting different DOM element and defining a placement of the relocated DOM element in relationship to the second DOM element by one of the following options:
