  • FsToolkit.ErrorHandling

    An opinionated F# Library for error handling

    • I'm having trouble following exactly what you're trying to do, but it would probably be easier if you used the builtin Result type in conjunction with FsToolkit.ErrorHandling. The library provides many useful combinators as well as a result, option, and resultOption computation expression.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
