Hello, We were having a discussion about unit testing keycloak-js in this PR: https://github.com/keycloak/keycloak/pull/5946 (closed). An easy way would be to extract it into a separate repository and write unit tests there.This would bring further benefits: - keycloak.js can be refactored to Typescript - file can be split in multiple modules - independent versioning from keycloak/keycloak would enable deprecating legacy Promises by enabling developers to use the keycloak-js version that works for them - keycloak-js-bower could also be deprecated. Guillaume Vincent previously proposed rewriting the Javascript Adapter ( https://lists.jboss.org/pipermail/keycloak-dev/2019-September/012457.html). Extracting it, writing tests for it and rewriting it afterwords is an option less prone to breaking changes. I have some free time and could start work on this. What do you think? Should I set up a repo so we can talk over code? Cheers, Armin
