State of GraphQL

State of GraphQL brings together core contributors, members of the GraphQL Foundation, and community leaders to talk about the future of GraphQL, and answer audience questions.

Hosts

Tracy Lee, CEO, This Dot Labs
Eve Porcello, Co-founder & Instructor, Moon Highway

Panelists

Uri Goldshtein, Founder, The Guild
Carlos Rufo, Engineering Lead, GraphCMS
Joey Nenni, Web Engineering Lead (GraphQL), PayPal
Janessa Garrow, Developer Experience Engineer, Apollo GraphQL
Tanmai Gopal, Founder, Hasura

GraphQL Updates

The first portion of the State of GraphQL covered updates from each panelist.

The GraphQL Foundation

One of the first topics covered by State of GraphQL was The GraphQL Foundation.

The GraphQL Foundation is a neutral foundation founded by global technology and application development companies. The GraphQL Foundation encourages contributions, stewardship, and a shared investment from a broad group in vendor-neutral events, documentation, tools, and support for GraphQL.

GraphQL.org

Uri opened up the conversation by emphasizing how open the foundation is. The GraphQL Foundation has always been open, but it's now easier than ever to become part of the community. The true "meat" of where the GraphQL action is though is in the GraphQL Working Group. There, topics such as changes to the GraphQL spec, ideas for new features, and more are discussed. Also, all the meetings are recorded and even summarized by text!

Apollo Odyssey

Odyssey is Apollo's free interactive learning platform.

Janessa from the Apollo team introduced us to Apollo Odyssey. Odyssey is Apollo's official learning platform. It was created to improve the developer experience of learning GraphQL. While some people may be able to learn effectively from docs, others may find different learning styles, like those offered by Odyssey, a more effective way of learning.

Courses offered range from the basics, like what are queries and resolvers, to the more advanced subjects, such as Apollo Federation.

Hasura

Tanmai from Hasura spoke next about updates done within Hasura. One of the biggest new features is support for cross-database joins over GraphQL. This update allows the developer to retrieve data from any number of data stores with efficient queries. The next thing being worked on now is end-to-end streaming.

PayPal

Joey Nenni of PayPal spoke about PayPal's experience with adopting GraphQL. He mentioned that once PayPal supported developers with tooling and sample apps, GraphQL spread like wildfire. Seeing the potential to do more with GraphQL, especially with sharing components, PayPal looked into Apollo Federation about 9 months ago, and as of about 2 weeks ago, they are now live with millions of requests already going through their gateway.

Joey also spoke about how GraphQL adoption is really about persistence. It's an iterative process. By making small steps, collecting small wins, and repeating that process, it becomes a lot easier to sell GraphQL. Joey coined the term "Guerilla Warfare" when it comes to finding successful implementations for GraphQL solutions.

GraphCMS

GraphCMS gives you instant GraphQL Content APIs to create, enrich, unify, and deliver your content across platforms.

GraphCMS recently hosted GraphQL Conf AND has recently raised $10 million in a Series A funding round. With all of this GraphQL focused momentum, GraphCMS is poising itself as a powerful solution for Headless CMS.

The ultimate content platform that enables you to deliver applications at scale.

Carlos Rufo

Defer and Stream

One important piece of information that Uri brought to the groups' attention was that defer, stream, live queries, and other features in spec proposals, but not in the actual spec, CAN BE USED SAFELY. Uri noticed a patter in production settings: once people have been given the option to use these new features, like defer, they see how valuable those features can be.

If you want to see more information involving these GraphQL directives, you can check out a blog post covering them here.

Apollo Federation

Implement a single graph across multiple services

Apollo Documentation

One very popular subject that is commonly brought up in Apollo conversations is Apollo Federation, and the idea of having a unified Graph connecting many services.

For PayPal, they spoke about the experiences encountered while transitioning some of their shared logic to a federated graph, while maintaining developer experience.

Apollo itself had a very positive experience using Apollo Federation. They ran into the need to unite two services, one written in Kotlin, and one in TypeScript, and have them run under a single gateway. This was a very big win and prevented the need for developers to learn additional languages to support a larger graph.

Tanmai had a balanced perspective on Apollo Federation:

Are we federating how the API comes together and presents itself? Or are we federating the execution itself?

He shared his experiences with analyzing where exactly a federated graph could be a good fit.

For Uri, he spoke about how the most important question is, "Are we actually making the product development faster?" Adopting Apollo Federation may give a different answer depending on the team and work being done.

Conclusion

GraphQL is still growing rapidly, and as shown in this State of GraphQL, there is a growing thriving community surrounding it. Continue the conversation, no matter your experience level, and check out the GraphQL Working Group. While this was a quick summary of the things spoken about during the State of GraphQL, you can catch the whole video on YouTube.

How to create and use custom GraphQL Scalars

How to create and use custom GraphQL Scalars In the realm of GraphQL, scalars form the bedrock of the type system, representing the most fundamental data types like strings, numbers, and booleans. As explored in our previous post, "Leveraging GraphQL Scalars to Enhance Your Schema," scalars play a pivotal role in defining how data is structured and validated. But what happens when the default scalars aren't quite enough? What happens when your application demands a data type as unique as its requirements? Enter the world of custom GraphQL scalars. These data types go beyond the conventional, offering the power and flexibility to tailor your schema to precisely match your application's unique needs. Whether handling complex data structures, enforcing specific data formats, or simply bringing clarity to your API, custom scalars open up a new realm of possibilities. In this post, we'll explore how to understand, create, and effectively utilize custom scalars in GraphQL. From conceptualization to implementation, we'll cover the essentials of extending your GraphQL toolkit, empowering you to transform abstract ideas into concrete, practical solutions. So, let's embark together on the journey of understanding and utilizing custom GraphQL scalars, enhancing and expanding the capabilities of your GraphQL schema. Understanding Custom Scalars Custom scalars in GraphQL extend beyond basic types like String or Int, allowing data to be defined, validated, and processed more precisely. They're instrumental when default types don't quite capture the complexity or specificity of the data, such as with specialized date formats or unique identifiers. The use of custom scalars brings several benefits: * Enhanced Clarity: They offer a clearer representation of what data looks like and how it behaves. * Built-in Validation: Data integrity is bolstered at the schema level. * Flexibility: They can be tailored to specific data handling needs, making your schema more adaptable and robust. With this understanding, we'll explore creating and integrating custom scalars into a GraphQL schema, turning theory into practice. Creating a Custom Scalar Defining a Custom Scalar in TypeScript: Creating a custom scalar in GraphQL with TypeScript involves defining its behavior through parsing, serialization, and validation functions. * Parsing: Transforms input data from the client into a server-understandable format. * Serializing: Converts server data back to a client-friendly format. * Validation: Ensures data adheres to the defined format or criteria. Example: A 'Color' Scalar in TypeScript The Color scalar will ensure that every color value adheres to a valid hexadecimal format, like #FFFFFF for white or #000000 for black: ` In this TypeScript implementation: * validateColors: a function that checks if the provided string matches the hexadecimal color format. * parseValue: a method function that converts the scalar’s value from the client into the server’s representation format - this method is called when a client provides the scalar as a variable. See parseValue docs for more information * serialize: a method function that converts the scalar’s server representation format to the client format, see serialize docs for more information * parseLiteral: similar to parseValue, this method function converts the scalar’s value from the client to the server’s representation format. Still, this method is called when the scalar is provided as a hard-coded argument (inline). See parseLiteral docs for more information In the upcoming section, we'll explore how to incorporate and validate these custom scalars within your schema, ensuring they function seamlessly in real-world scenarios. Integrating Custom Scalars into a Schema Incorporating the 'Color' Scalar After defining your custom Color scalar, the next crucial step is effectively integrating it into your GraphQL schema. This integration ensures that your GraphQL server recognizes and correctly utilizes the scalar. Step-by-Step Integration 1. Add the scalar to Type Definitions: Include the Color scalar in your GraphQL type definitions. This inclusion informs GraphQL about this new scalar type. 2. Resolver Mapping: Map your custom scalar type to its resolver. This connection is key for GraphQL to understand how to process this type during queries and mutations. ` 1. Use the scalar: Update your type to use the new custom scalar ` Testing the Integration With your custom Color scalar integrated, conducting thorough testing is vital. Ensure that your GraphQL server correctly handles the Color scalar, particularly in terms of accepting valid color formats and rejecting invalid ones. For demonstration purposes, I've adapted a creation mutation to include the primaryColor field. To keep this post focused and concise, I won't detail all the code changes here, but the following screenshots illustrate the successful implementation and error handling. Calling the mutation (createTechnology) successfully: Calling the mutation with forced fail (bad color hex): Conclusion The journey into the realm of custom GraphQL scalars reveals a world where data types are no longer confined to the basics. By creating and integrating scalars like the Color type, we unlock precision and specificity in our GraphQL schemas, which significantly enhance our applications' data handling capabilities. Custom scalars are more than just a technical addition; they testify to GraphQL's flexibility and power. They allow developers to express data meaningfully, ensuring that APIs are functional, intuitive, and robust. As we've seen, defining, integrating, and testing these scalars requires a blend of creativity and technical acumen. It encourages a deeper understanding of how data flows through your application and offers a chance to tailor that experience to your project's unique needs. So, as you embark on your GraphQL journey, consider the potential of custom scalars. Whether you're ensuring data integrity, enhancing API clarity, or simply making your schema a perfect fit for your application, the possibilities are as vast as they are exciting. Embrace the power of customization, and let your GraphQL schemas shine!...

Class and Enum Typings for Handling Data with GraphQL

Intro Today we’ll talk about class and enum typings for handling more complex data with GraphQL. The typings will be used on class objects to make them easier to read and understand. This blog will build on the concepts of another blog found here, in which I discussed wrapping and enhancing data, which talks about how to create a GraphQL Rest API wrapper, and how to enhance your data. This article assumes you have a basic understanding of classes, typing, and enums. Here is the code repo if you want to review it while reading, or just skip ahead. With that said, we will look at the class structure we’re going to be using, the enums, and the type lookup for our customField enum with our mapper. Class setup This class we’re going to set up will be strictly for typing. We’re going to make a RestaurantGuest class as this data will be restaurant themed. So in our restaurant.ts file, we will name it RestaurantGuest, and include a few different items. *Basic starting class example* ` After setting that up, we will add a type that will reference the above class. *Type example* ` This type will be used later when we do the type lookup in conjunction with our mapper function. With the above finished, we can now move on to handling our enums. Handling enums We’ll now create our Enum to make dealing with our complex data easier. Since the above 3249258 represents FoodReservation, we will create an enum for it. Now you might be wondering why 3249258 represents FoodReservation. Unfortunately, this is an example of how data can be returned to us from a call. It could be due to the field id established in a CMS such as Contentful, or from another source that we don’t control. This isn’t readable, so we’re creating an Enum for the value. *Enum example* ` This will be used later during our type look-up. Type lookup Now we can start combining the enum from above with our class type, and a look-up type that we’re about to create. So let's make another type called RestaurantGuestFieldLookup, which will have an id and value. *Look-up type example* ` Perfect, now we’ll swap out ` to be ` We can now move on to creating and using our mapper. In a separate file called mapper.ts, we will create our restaruantGuestMapper function. ` Tada! Thanks to all the work above, we can easily understand and get back the data we need. Conclusion Today's article covered setting up a typing class, creating an enum, and type lookup with a mapper for more complex data handling with GraphQL. Hopefully, the class structure was straightforward and helpful, along with the enums and type lookup and formatting examples.

How to make Videos with React using Remotion

How to make Videos with React using Remotion We've written a blog post discussing how React truly is a "Learn Once, Write Anywhere" library. In that article, we talked about how we aren't limited to rendering React components to the DOM. In this post, we'll discuss how we can leverage our knowledge of developing React components and create Videos, using Remotion. If you already know [React] and follow along with this post, you'll walk away with a custom .mp4 video of you're own creation, and the knowledge of how to customize it to you're heart's content. Remotion Remotion is a suite of libraries for creating videos programmatically with React. Just like react-dom is used to provide an interface between React components, and rendering to the DOM, Remotion is used to provide an interface between React and rendering to Video. > If you know React, you can make videos. > -- Remotion Documentation This is exciting because it allows developers to re-use their knowledge of the React library for yet another purpose. Let's dive in and see how we can start rendering some videos! Initializing a Remotion Video Project Creating a new Remotion video is as easy as a 1 line command: npm init video Running this command gives the user access to a few default templates for Remotion video development: - Hello World - Blank - Hello World (Vanilla Javascript) - React Three Fiber - Still Images - Text to Speech The Hello World templates are fantastic places to go if you are a hands-on learner and like playing around with your code in a live dev environment. They're how I learned to use Remotion. They're packed with such great logic, that I'd encourage you to run a template before moving on and exploring them a bit to see how things are laid out. That being said, I want to go over things rather slowly, so I'm going to create a repo from the Blank template, add a few development features (linting, husky, prettier, etc), and use that as a starting point. If you want to develop with these features and want a similar starting point, clone the repo here and you can see every commit from beginning to end. This is the exact commit after I finished installing linting to the Blank template. The Blank Remotion Template If you cloned the repo I mentioned above, you'll be working in the Blank template, with a few additional dev features. The main 2 files are: - src\index.tsx: This is similar to the index file of a regular create-react-app. It uses a render function to take a React component, and render it to the desired output, in this case, a .mp4 video. We won't be looking in here. - src\Video.tsx: This is the main entry point of our video. Think of this as the App component in a create-react-app project. It's here that we layer together React components to create our Remotion video. This is where we will start to focus our attention. The Composition component The entry point file Video.tsx introduces us to our first Remotion component, Composition. ` We can see this component in action by running npm start and checkouting out our development environment: The Remotion development environment has 4 important sections: - Compositions: The left main column. This is a list of all defined Composition components in Video.tsx. The Blank template defines a single Composition, with an id == 'Empty' - Scenes: The bottom left column. We haven't talked about scenes yet... - Composition Render: The main dev zone. This is the development render of the currently selected Composition. - Composition Timeline: This is a timeline of scenes rendered in the currently selected Composition. The Composition component has a few important properties: - id: This is the name given to the Composition, used to identify the component in the development environment. - component: This is the component that the Composition renders. Different compositions can render the same component, for responsiveness for example. - durationInFrames & fps: A Composition is not defined by how long it is in time, but by how many frames it is made up of, and how fast those frames are rendered. - width & height: Together, these define the aspect ratio of our video. You could define an HD Composition with a 1920/1080 width/height, or a square still from a single frame of a Component with a 200/200 width/height for example. - defaultProps: This is the props object passed into the component when the Composition is rendered. This repository defines a super small empty component as the component-to-render for the Empty composition. Let's rename our component to HelloWorld, and create a full-fledged component to render. We'll render a simple, 4-second video, of the text "Hello, World!", in high definition, at 60fps. src/Video.tsx ` src/components/HelloWorld.tsx ` To render this to .mp4 you need to have ffmpeg installed. Adjust the package.json build command and instruct the CLI to render our HelloWorld composition, and run npm run build to create our first video! Here's a link to what this would render. It's nothing crazy, but with previous React knowledge, and with the help of Remotion, we have created a 4 second long, 60fps, 4K video! Simple animations with interpolate Rendering some static text to video doesn't make for an exciting video, so let's learn how to reach into the state of the application, and adjust the style of our text, depending on the current frame. Here are the 2 hooks we'll use to accomplish this: - useCurrentFrame: This hook returns the current frame number. - interpolate: This hook helps the user change values throughout several frames. It takes in 3 arguments, the current frame (from useCurrentFrame), a tuple designating the start and end frame for the interpolation, and another tuple defining the start and end values for the frame duration. Using these 2 hooks, we can define what the opacity of our text should be, as a function of the current frame: ` Here's a link to what this would render. We aren't rendering static text anymore. Now we have a real video! The Sequence component Videos can be made up of MANY moving parts though. Our current video only has 1 moving part, but let's add some complexity to the video and split this into 2 parts. To do this, we need to take advantage of the Sequence component. > Using a Sequence, you can time-shift certain parts of your animation and therefore make them more reusable. Sequences are also shown in the timeline and help you visually understand the structure of your video. > -- Remotion Docs We can use sequences to help us break apart our logic even further, and we can also view these sequences on our composition timeline. Here are some important props for the Sequence component: - from (required, number): The frame that the Sequence children start at. The initial frame for them is 0. - durationInFrames (optional, default: Infinity): This is how many frames a sequence is displayed. - name (optional): Name your sequences to label them in the development environment. - layout (optional, default: 'absolute-fill'): Sequences are positioned absolutely initially, use this to handle layout manually. Let's animate our "Hello, World!" a bit more: src/components/HelloWorld.tsx ` With a few sequences, we are now separating our animations, and labeling them in our dev environment. Here is the render uploaded to YouTube. Putting the 'World' in 'Hello, World!' Being able to render text is amazing, but in the animation world, models aren't drawn manually with code. Instead, they're generated using software, such as Blender for example. One of the tools we can render with using Remotion is React Three Fiber. Just like Remotion lets us render to a Video format, React Three Fiber allows us to render React components into ThreeJS, a WebGL library. With a bit of React Three Fiber logic and a publicly available model of our planet, we can put the 'World' in 'Hello, World!' Hello, World! Going into how to work with React Three Fiber is a bit out of the scope of this post, but I wanted to show just what the developer is capable of with Remotion, and rendering a spinning planet with JSX is pretty amazing. src/components/HelloWorld.tsx ` Conclusion React truly is a "Learn Once, Write Anywhere" language. The DOM is nowhere close to the only render target React is capable of. With Remotion, we've learned how to slap together some JSX and hooks, and render actual videos, programmatically. Feel free to clone the repo and play around with the logic. If you've followed along with this post, you can now proudly state that you can literally render "Hello, World!" with React!...

“Music and code have a lot in common,” freeCodeCamp’s Jessica Wilkins on what the tech community is doing right to onboard new software engineers

Before she was a software developer at freeCodeCamp, Jessica Wilkins was a classically trained clarinetist performing across the country. Her days were filled with rehearsals, concerts, and teaching, and she hadn’t considered a tech career until the world changed in 2020. > “When the pandemic hit, most of my gigs were canceled,” she says. “I suddenly had time on my hands and an idea for a site I wanted to build.” That site, a tribute to Black musicians in classical and jazz music, turned into much more than a personal project. It opened the door to a whole new career where her creative instincts and curiosity could thrive just as much as they had in music. Now at freeCodeCamp, Jessica maintains and develops the very JavaScript curriculum that has helped her and millions of developers around the world. We spoke with Jessica about her advice for JavaScript learners, why musicians make great developers, and how inclusive communities are helping more women thrive in tech. Jessica’s Top 3 JavaScript Skill Picks for 2025 If you ask Jessica what it takes to succeed as a JavaScript developer in 2025, she won’t point you straight to the newest library or trend. Instead, she lists three skills that sound simple, but take real time to build: > “Learning how to ask questions and research when you get stuck. Learning how to read error messages. And having a strong foundation in the fundamentals” She says those skills don’t come from shortcuts or shiny tools. They come from building. > “Start with small projects and keep building,” she says. “Books like You Don’t Know JS help you understand the theory, but experience comes from writing and shipping code. You learn a lot by doing.” And don’t forget the people around you. > “Meetups and conferences are amazing,” she adds. “You’ll pick up things faster, get feedback, and make friends who are learning alongside you.” Why So Many Musicians End Up in Tech A musical past like Jessica’s isn’t unheard of in the JavaScript industry. In fact, she’s noticed a surprising number of musicians making the leap into software. > “I think it’s because music and code have a lot in common,” she says. “They both require creativity, pattern recognition, problem-solving… and you can really get into flow when you’re deep in either one.” That crossover between artistry and logic feels like home to people who’ve lived in both worlds. What the Tech Community Is Getting Right Jessica has seen both the challenges and the wins when it comes to supporting women in tech. > “There’s still a lot of toxicity in some corners,” she says. “But the communities that are doing it right—like Women Who Code, Women in Tech, and Virtual Coffee—create safe, supportive spaces to grow and share experiences.” She believes those spaces aren’t just helpful, but they’re essential. > “Having a network makes a huge difference, especially early in your career.” What’s Next for Jessica Wilkins? With a catalog of published articles, open-source projects under her belt, and a growing audience of devs following her journey, Jessica is just getting started. She’s still writing. Still mentoring. Still building. And still proving that creativity doesn’t stop at the orchestra pit—it just finds a new stage. Follow Jessica Wilkins on X and Linkedin to keep up with her work in tech, her musical roots, and whatever she’s building next. Sticker illustration by Jacob Ashley....
