GraphQL has gained popularity for its ability to offer more flexibility and performance over traditional REST APIs. Strawberry is a new and fast-growing GraphQL library for Python, inspired by dataclasses functionality, that offers a modern and intuitive API for building GraphQL APIs using type hints.
In this talk, we will explore the basics of building a GraphQL API with Strawberry and how it can be integrated with Django in a performant and type-safe way, by generating its types and resolvers directly from Django models. We will also compare and contrast the benefits and drawbacks of GraphQL versus REST APIs, including how GraphQL can help improve frontend development workflows.
Attendees will come away with an understanding of how Strawberry can help simplify the process of building and maintaining GraphQL APIs, and how to use its powerful features to optimize for performance, safety, and flexibility, while also covering its drawbacks and how to avoid some common issues.
In this talk, we will explore the world of GraphQL APIs with Strawberry, a new Python library that makes it easy to create GraphQL APIs with Django. We will dive into what GraphQL is, how it compares to traditional RESTful APIs, and what makes Strawberry stand out from other Python GraphQL libraries.
One of the biggest challenges in GraphQL API development is the N+1 problem, where queries can become exponentially slow as more data is requested. We will discuss how data loaders can help solve this problem, and go in-depth on how to use them in Strawberry. In this topic we will also cover some extensions that leverage query introspection and user defined hints to automatically call .only()/.select_related()/..prefetch_related() on querysets, making your queries more efficient and avoiding common pitfalls. This is especially important in high-traffic, production environments where performance is critical.
Finally, we will showcase some of the benefits of using Strawberry and Django together, including a type-safe approach to API development and streamlined code maintenance. By the end of this talk, you'll have the knowledge and tools you need to create high-performance GraphQL APIs with Strawberry and Django.
It will be presented in the following order:
- Intro
- What is GraphQL and how it compares to other approaches, like REST
- Writing general GraphQL APIs using Strawberry
- Integrating the Django ORM with Strawberry
- Some common pitfalls, with emphasis on the N+1 problem
- GraphQL tools to avoid those pitfalls and how to use them with Strawberry
- How some libs uses introspection to automatically overcome those pitfalls and also improve performance when executing Django querysets
