StepZen is a platform to build and deploy GraphQL APIs that integrates and aggregate data from various sources. In the demo section, I will show how to build a GraphQL API in declarative code using StepZen.

Great! With this, we've implemented the login flow using Auth0 and StepZen. You can find the complete source code for this blog post on GitHub.

The final step is to use GraphQL. We'll create a free account on StepZen. Once logged-in, we can access the Account, Admin Key and API Key.

You can find a complete example of using StepZen to implement the Authorization Code flow in the StepZen GitHub repository.

Have a look at https://stepzen.com, which allows you to federate any data source no matter the framework or service used to create it. It has a generous free tier

When moving away from Apollo Server, and you're looking for a replacement built with JavaScript or TypeScript, let me give you some options. If you want to keep building your GraphQL API schema first, you might want to consider Mercurius (which relies on Fastify) or GraphQL Yoga. If you're going to build your GraphQL API code or resolver first, have a look at TypeGraphQL or Nexus. Alternatively, there are great GraphQL-as-a-Service solutions such as StepZen in case you no longer want to build, maintain and host your own GraphQL API.

But you can also build a GraphQL API using a code-first GraphQL server library. This means you can write the resolvers and then generate the schema from the resolvers. Code-first libraries are much closer to tRPC in terms of Developer Experience but still more challenging than using a GraphQL-as-a-service like StepZen.

After installing, you can choose to run StepZen locally using Docker or in the cloud by signing up for a free account at stepzen.com. For this example, we'll be using the cloud version, for which you can sign up for a free account using your GitHub account.

StepZen is participating in Hacktoberfest, and you can contribute by adding a new integration or improving an existing integration in our Examples repository. Every PR to this repository will count towards your Hacktoberfest goals.

To get a GraphQL using StepZen, you can connect your data source or use one of the pre-built examples from Github. In this post, we'll be taking a GraphQL API created on top off a MySQL database from the examples. By cloning this repository to your local machine, you'll get a set of configuration files and .graphql files containing the GraphQL schema. To run the GraphQL API and deploy it to the cloud, you need to be using the StepZen CLI.

GraphQL Gateway is primarily responsible for serving GraphQL queries to consumers. It takes a query from a client, breaks it into smaller sub-queries, and executes that plan by proxying calls to the appropriate downstream subgraphs. When we started our journey, there was only Apollo Federation in the arena, and we used it. Still, now you can look at other options (e.g. Mercurius, Conductor, Hot Chocolate, Wundergraph, Hasura Remote Schemas), compare benchmarks and decide what's important and preferable for your needs. The Gateway provides a unified API for consumers while giving backend engineers flexibility and service isolation.

If you're using Fastify with Mercurius as your GraphQL adapter, you may be looking for some advanced usages. In this article, we'll explore a real world example with Dynamic GQL queries with Mercurius.

Loader: it is a built-in DataLoader-Like solution that is quick to set up and use.

In this post I will show you how to implement NestJS😻 with GraphQL in code first mode, using Mercurius and the "platform" to Fastify.

What this does is to overwrite or augment the types exposed by the pointed module, and can be used (for example) when relying on autogenerated code. One interesting case of this is GraphQL to TypeScript code generation, and how this is integrated with the amazing Mercurius library (made by some of my colleagues at NearForm! 😜).

Let's start with data. We live in amazing times and it's really easy and cheap (or free) to get started with storing and working with data online. Take for example a PlanetScale MySQL-compatible database, Fastify Node.js Server, Prisma database mapper and a GraphQL connector like Mercurius and you have an entire backend stack. For this example we assume you already have a backend or you want to connect to a 3rd party database like the GitHub GraphQL API.

In this chapter, we assume a basic understanding of GraphQL and focus on how to work with the built-in @nestjs/graphql module. The GraphQLModule can be configured to use Apollo server (with the @nestjs/apollo driver) and Mercurius (with the @nestjs/mercurius). We provide official integrations for these proven GraphQL packages to provide a simple way to use GraphQL with Nest. You can also build your own dedicated driver (read more on that here).

Why would I want to use Apollo Client? So far in my career I have used some server graphql scaffolding (webonyx/graphql-php for PHP and mercurius for Node) and just used the fetch API (or whatever ajax API around XMLHttpRequest) against that server with the body being an object with

Only for people who are clueless. Apollo server is probably the worst node.js server to use for your graphql schema. It's terribly slow. You should look into https://mercurius.dev
