Create your own state management library - LNUG July 2019

Wednesday, 24 July 2019


How hard is it to make your own state management library? By using React hooks, Context and other open source projects you can easily build your own useful library.

I wanted first class TypeScript support, immutable data, zero boilerplate and hassle free wiring. I built it in a few dozen lines of code: Immutable Context.

I'll demo how to use it via a Code Sandbox demo, how it works under the hood and then look at some lessons learned, with suggestions on how to build your own state management library in 2019.
