DevCycle Bucketing - Assembly Script Lib

This package contains the shared logic used by DevCycle products to evaluate a user's information against a set of segmentation filters and determine eligibility for a given feature. It also makes decisions about which variation to serve a user in a multi-variate feature.

This Assembly Script version of the Bucketing library is designed to be used in a cross-platform manner as it builds a WebAssembly output that can be executed in various JavaScript Web / NodeJS environments and other server-side SDK environments. WebAssembly is a binary format that can be executed in a Web browser, NodeJS, or any other environment that supports it.

See the AssemblyScript Documentation for further details: https://www.assemblyscript.org/introduction.html

Usage

Building WebAssembly

yarn nx build shared-bucketing-as

See WebAssembly output in /build folder.

Compile Protobuf Files

When working on the Protobuf types you will need to compile those types into JS and AssemblyScript files. To do this:

yarn nx run shared-bucketing-as:compile-pb

Testing

yarn nx test shared-bucketing-as

Benchmarking

yarn nx run shared-bucketing-as:benchmark

Current benchmark results on M1 Pro Macbook Pro:
