[keycloak-user] Keycloak Javascript Adapter - How Tied to Keycloak?

Hi, Bit of a strange question from me. How tied to Keycloak server is the Keycloak Javascript adapter when it comes to enabling OIDC and OAuth2 flows? If we have a client application written using it, would it be possible to replace Keycloak with another compliant identity provider (like AzureAD or Auth0)? Cheers, Ben Ashley
