GraphQL Schema Design | mysimulator.uk

The Core Idea

Deep learning relies on representing data across layered feature spaces.

This layered approach allows the system to learn increasingly complex patterns from raw input.

Filtering and Pagination

Effective filtering and pagination are crucial for handling large datasets efficiently.

Implementing these features correctly minimizes server load and improves the user experience during data retrieval.

Use Specific Types: Avoid Generic Types

Nullability: Be conservative with non-null fields, use nullable for optional data.

Naming Conventions: Utilize PascalCase for types and camelCase for field names. Use SCREAMING_SNAKE_CASE for enum values.

Frequently asked questions

What is deep learning?

Deep learning is a family of machine learning methods that use multi-layer neural networks to analyze data.

GraphQL doesn't use URL versioning – how does it manage changes?

GraphQL avoids URL-based versioning by allowing new fields to be added without removing existing ones. It uses deprecation directives, input type modifications, union types for expansion, and argument additions to evolve the schema gracefully.

Should I use a list for small, fixed collections?

Yes, you should. Lists are ideal for representing small, unchanging collections like enum values, status codes, or data that’s always fully available. Connection patterns are better suited for large, dynamic datasets requiring pagination and cursor-based navigation.

What's the difference between Union Types (mutation returns a Union type) and the Payload Pattern?

Union types require fragments for error handling, while the Payload pattern always returns a payload with result and errors fields. The Payload pattern is preferred because it simplifies error management and avoids unnecessary fragment usage.

Should I use non-null (!) for required fields?

Use non-null (!) for fields that are always present, required input types, or guaranteed to be available after object creation. Use nullable for optional fields, permissions checks, or data potentially null in certain contexts.
