In this workshop, you’ll learn how to build a Next.js app that uses Apollo Client to fetch data from a headless WordPress backend and use it to render the pages of your app. You’ll learn when you should consider a headless WordPress architecture, how to turn a WordPress backend into a GraphQL server, how to compose queries using the GraphiQL IDE, how to colocate GraphQL fragments with your components, and more.

This workshop has been presented at React Summit 2022, check out the latest edition of this React Conference.

FAQ

Benefits of using a Headless WordPress approach include keeping the preferred CMS for content creators, improved performance and scalability, a platform-agnostic backend, the ability to pull data from multiple sources, increased security, and an improved developer experience with component-based architectures.

You can turn a WordPress site into a GraphQL server by installing and activating the WPGraphQL plugin. This plugin provides a GraphQL endpoint that the frontend application can query to fetch data.

WPGraphQL is a free, open-source plugin for WordPress that turns any WordPress site into a GraphQL API. It is used in a Headless WordPress setup to allow the frontend JavaScript application to communicate with the WordPress backend efficiently, enabling more powerful and flexible data queries compared to the traditional REST API.

The presenter of the workshop is Kellan Mace, who works at WP Engine, a popular hosting platform specifically for WordPress sites. WP Engine recently launched Atlas, a hosting platform geared towards Headless WordPress sites.

Drawbacks include additional complexity with more moving pieces, the need to recreate some built-in WordPress features like user authentication and post previews, inability to use WordPress plugins to add visual elements, and the inability to use new full-site editing features in WordPress 6.0.

The workshop focuses on building a Headless WordPress application using Next.js and WP GraphQL. It covers topics such as the differences between traditional and Headless WordPress, the benefits of going Headless, and includes a live coding session to create a Next.js app connected to a WordPress backend via GraphQL.

For dynamic pages like search results, the workshop uses Apollo Client's useQuery hook to run GraphQL queries on the client side. This allows the application to fetch data in real-time based on user input and update the UI accordingly.

The workshop uses Apollo Client to manage GraphQL queries on the client side. Apollo Client provides features like in-memory caching, hooks for running queries and mutations, and tools for handling loading and error states.

GraphQL fragments are reusable units of a GraphQL query that can be defined once and then included in multiple queries. In the workshop, fragments are used to co-locate a component’s data requirements with the component itself, improving code organization and maintainability.

The graphical IDE (GraphiQL) is used to compose and test GraphQL queries. It provides a user-friendly interface to explore the GraphQL schema, build queries, and see the responses. This is particularly useful for ensuring that the queries return the expected data before integrating them into the frontend application.

Knowledge of AI tooling is critical for future-proofing the careers of React developers, and the Vercel suite of AI tools is an approachable on-ramp. In this course, we’ll take a closer look at the Vercel AI SDK and how this can help React developers build streaming interfaces with JavaScript and Next.js. We’ll also incorporate additional 3rd party APIs to build and deploy a music visualization app.
Topics:- Creating a React Project with Next.js- Choosing a LLM- Customizing Streaming Interfaces- Building Routes- Creating and Generating Components - Using Hooks (useChat, useCompletion, useActions, etc)

Frontend issues that affect your users are often triggered by backend problems. In this workshop, you’ll learn how to identify issues causing slow web pages and poor Core Web Vitals using tracing.
Then, try it for yourself by setting up Sentry in a ready-made Next.js project to discover performance issues including slow database queries in an interactive pair-programming session.
You’ll leave the workshop being able to:- Find backend issues that might be slowing down your frontend apps- Setup tracing with Sentry in a Next.js project- Debug and fix poor performance issues using tracing
This will be a live 2-hour event where you’ll have the opportunity to code along with us and ask us questions.

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.

In this workshop we'll dig deeper into data modeling. We'll start with a discussion about various database types and how they map to GraphQL. Once that groundwork is laid out, the focus will shift to specific types of databases and how to build data models that work best for GraphQL within various scenarios.

If you’re like me, you probably have a million side-project ideas, some that could even make you money as a micro SaaS, or could turn out to be the next billion dollar startup. But how do you know which ones? How do you go from an idea into a functioning product that can be put into the hands of paying customers without quitting your job and sinking all of your time and investment into it? How can your solo side-projects compete with applications built by enormous teams and large enterprise companies?
Building rich SaaS products comes with technical challenges like infrastructure, scaling, availability, security, and complicated subsystems like auth and payments. This is why it’s often the already established tech giants who can reasonably build and operate products like that. However, a new generation of devtools are enabling us developers to easily build complete solutions that take advantage of the best cloud infrastructure available, and offer an experience that allows you to rapidly iterate on your ideas for a low cost of $0. They take all the technical challenges of building and operating software products away from you so that you only have to spend your time building the features that your users want, giving you a reasonable chance to compete against the market by staying incredibly agile and responsive to the needs of users.
In this 3 hour workshop you will start with a simple task management application built with React and Next.js and turn it into a scalable and fully functioning SaaS product by integrating a scalable database (PlanetScale), multi-tenant authentication (Clerk), and subscription based payments (Stripe). You will also learn how the principles of agile software development and domain driven design can help you build products quickly and cost-efficiently, and compete with existing solutions.

Routing in React 18 and Beyond
Top Content
Routing in React 18 brings a native app-like user experience and allows applications to transition between different environments. React Router and Next.js have different approaches to routing, with React Router using component-based routing and Next.js using file system-based routing. React server components provide the primitives to address the disadvantages of multipage applications while maintaining the same user experience. Improving navigation and routing in React involves including loading UI, pre-rendering parts of the screen, and using server components for more performant experiences. Next.js and Remix are moving towards a converging solution by combining component-based routing with file system routing.

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.
