graphql domain driven design react

Video Summary and Transcription

The video explores building enterprise-grade GraphQL APIs using domain-driven design (DDD) and clean architecture. It delves into how GraphQL clean architecture supports efficient data fetching and performance enhancement. The talk highlights the role of GraphQL DDD in aligning software with business requirements, focusing on core business logic. Key components of GraphQL architecture include defining schemas and resolvers that map GraphQL types with business domain types. The speaker emphasizes the central role of GraphQL business logic in integrating all business-related logic, which simplifies refactoring and design improvement. The use of technologies like Node.js, Express, TypeScript, and Apollo Server in building the GraphQL API is discussed. Domain-driven design and clean architecture are explored as strategies to enhance software scalability and maintainability.

This talk has been presented at React Day Berlin 2023, check out the latest edition of this React Conference.

FAQ

Peter Ivanov is a developer at the outsourcing consulting company Ant S6, based in Sofia, Bulgaria. He considers himself a T-shaped developer and shares his knowledge through his personal website and newsletter.

The purpose of Peter Ivanov's presentation is to share his experience in building a scalable and maintainable GraphQL API by embracing TypeScript, domain-driven design (DDD), and clean architecture.

A T-shaped developer is a professional who has deep knowledge in a specific area (the vertical bar of the 'T') and a broad understanding of general skills (the horizontal bar of the 'T'). Peter Ivanov has written a blog post about it on his personal website.

Backstadium.com is a service similar to DigitalOcean or AWS for Mac infrastructure. It allows users to run applications on virtual Mac hardware without purchasing the physical Mac.

Some lessons learned include the difficulty of getting it right from the beginning, the importance of scheduling time for paying off technical debt, and the need to adapt DDD and clean architecture principles to suit specific needs and experiences.

The technologies used include Node.js, Express, TypeScript, Apollo Server, and GraphQL.

Clean architecture is a layered architecture pattern that allows for better separation of concerns, making the codebase easier to test and maintain. Each layer points inward, ensuring a single flow of dependencies.

Domain-driven design (DDD) emphasizes the importance of understanding the business domain and helps teams focus on core business logic. It ensures that software aligns with business requirements through concepts like ubiquitous language and bounded contexts.

Key components include entities, domain services, application services, repositories, GraphQL schema, GraphQL resolvers, and module APIs. Each bounded context, such as account management and billing management, defines its own structure.

GraphQL was chosen for its ability to serve as a central place for all business-related logic, making it easier to refactor and improve the design of the database and overall architecture.

GitHub cofounder, RedwoodJS author

Tom Pressenwurter introduces Redwood.js, a full stack app framework for building GraphQL APIs easily and maintainably. He demonstrates a Redwood.js application with a React-based front end and a Node.js API. Redwood.js offers a simplified folder structure and schema for organizing the application. It provides easy data manipulation and CRUD operations through GraphQL functions. Redwood.js allows for easy implementation of new queries and directives, including authentication and limiting access to data. It is a stable and production-ready framework that integrates well with other front-end technologies.

This Talk discusses handling local state in software development, particularly when dealing with asynchronous behavior and API requests. It explores the challenges of managing global state and the need for actions when handling server data. The Talk also highlights the issue of fetching data not in Vuex and the challenges of keeping data up-to-date in Vuex. It mentions alternative tools like Apollo Client and React Query for handling local state. The Talk concludes with a discussion on GitLab going public and the celebration that followed.

Step aside resolvers: a new approach to GraphQL execution

Benjie

GraphQL Technical Steering Committee

GraphQL has made a huge impact in the way we build client applications, websites, and mobile apps. Despite the dominance of resolvers, the GraphQL specification does not mandate their use. Introducing Graphast, a new project that compiles GraphQL operations into execution and output plans, providing advanced optimizations. In GraphFast, instead of resolvers, we have plan resolvers that deal with future data. Graphfast plan resolvers are short and efficient, supporting all features of modern GraphQL.

Scott Spence

Have you ever thought about building something that doesn't require a lot of boilerplate with a tiny bundle size? In this workshop, Scott Spence will go from hello world to covering routing and using endpoints in SvelteKit. You'll set up a backend GraphQL API then use GraphQL queries with SvelteKit to display the GraphQL API data. You'll build a fast secure project that uses SvelteKit's features, then deploy it as a fully static site. This course is for the Svelte curious who haven't had extensive experience with SvelteKit and want a deeper understanding of how to use it in practical applications.

GraphQL for React Developers

Featured Workshop

Roy Derks

There are many advantages to using GraphQL as a datasource for frontend development, compared to REST APIs. We developers in example need to write a lot of imperative code to retrieve data to display in our applications and handle state. With GraphQL you cannot only decrease the amount of code needed around data fetching and state-management you'll also get increased flexibility, better performance and most of all an improved developer experience. In this workshop you'll learn how GraphQL can improve your work as a frontend developer and how to handle GraphQL in your frontend React application.
