Question 1

How to validate nested maps with Skooma?

Accepted Answer

Define schemas as nested Elixir maps, like %{stats: %{hp: :int}}, or use functions for recursive structures, as shown in the complex schemas section. Error messages will trace the path for easy debugging.

Question 2

Skooma vs Ecto Changeset for validation in Elixir?

Accepted Answer

Skooma is lightweight and schema-agnostic, ideal for general data validation, while Ecto Changesets are tied to database operations and offer more built-in features. Use Skooma for API payloads and Ecto for model validation.

Question 3

Can Skooma validate datetime or time types?

Accepted Answer

No, Skooma only supports core Elixir types like strings and integers; for datetime validation, you'd need to use custom validators or convert data first, as it's not mentioned in the built-in types.

Question 4

Is Skooma production-ready for high-traffic apps?

Accepted Answer

While functional, its performance in large-scale systems isn't highlighted, and as a young library (v0.2.0), it might lack optimizations found in more mature alternatives. Test thoroughly for your use case.

Question 5

How to handle conditional validation with Skooma?

Accepted Answer

Use custom validators or union types to implement conditional logic, but there's no built-in support for dependencies between fields, requiring extra code compared to some libraries.

Question 6

What are the alternatives to Skooma for Elixir validation?

Accepted Answer

Libraries like Vex or Ecto Changesets offer more features but with higher complexity. Skooma shines for simplicity, but if you need advanced validators or integration, consider other options.
