Question 1

How do I connect Diana.jl to a SQL database?

Accepted Answer

Since Diana.jl is data agnostic, you need to write custom resolvers that interface with Julia database libraries like SQLite.jl or PostgreSQL.jl to fetch and expose data through GraphQL queries. The README shows resolver examples using dictionaries, which can be adapted.

Question 2

Is Diana.jl or GraphQL.jl better for Julia?

Accepted Answer

Diana.jl offers both client and server support, while GraphQL.jl may have different focuses or maturity levels; based on the README, Diana.jl is more feature-complete for basic use but check community activity and documentation for the latest comparisons. Currently, Diana.jl's TODO list indicates gaps in advanced features.

Question 3

Can I use Diana.jl for real-time apps with subscriptions?

Accepted Answer

No, subscriptions execution is listed as a TODO item in the README, so Diana.jl does not yet support real-time GraphQL features. You would need to implement workarounds or consider alternative solutions for live data updates.

Question 4

How to handle authentication in a Diana.jl GraphQL server?

Accepted Answer

Authentication can be implemented in resolvers by accessing context or arguments, but middleware support is listed as incomplete in the TODO. For basic cases, you can pass auth tokens via the client example's 'auth' parameter or manually validate in resolver functions.

Question 5

Does Diana.jl work with GraphQL tools like GraphiQL?

Accepted Answer

Not directly, as introspection is on the TODO list, meaning many GraphQL tooling that relies on schema introspection for UI or validation may not function properly with Diana.jl servers without manual configuration or custom implementations.

Question 6

What's the performance like for complex queries in Diana.jl?

Accepted Answer

As a Julia implementation, it can leverage Julia's performance for data processing, but the missing features like complex types and fragments might limit optimization for nested or large queries. Benchmarks are not provided in the README, so testing with your use case is recommended.
