Foldkit: An Effect-First Frontend Framework #9
Get support from the Effect community (https://discord.gg/effect-ts)
Devin Jameson joins Cause & Effect to talk about Foldkit (https://foldkit.dev/), an Effect-first frontend framework inspired by Elm architecture. Devin and Johannes Schickling discuss why Foldkit takes a schema-first approach to frontend state, how it differs from React, how commands model side effects, and why this architecture may be especially useful in the age of AI-assisted coding.
