What is WunderGraph?

WunderGraph is the Next-Generation API Developer Platform with a focus on Developer Experience.

At its core, WunderGraph combines the API Gateway pattern with the Backend for Frontend (BFF) pattern to create the perfect Developer Experience for working with APIs.

Take all your (micro-)services, Databases, File Storages, Identity Providers as well as 3rd party APIs and combine them into your own Firebase-like Developer Toolkit, without getting locked into a specific vendor.

Imagine that each of your applications could have its own dedicated BFF, while being able to share common logic across all your applications, that’s the WunderGraph Experience.

Architecture & Key Differentiators

WunderGraph is unique in its design, as we’re not directly exposing GraphQL, but JSON-RPC. Combined with a generated Type-Safe client, this leads to a unique Developer Experience. You can learn more about the architecture of WunderGraph and why we’ve built it this way in the architecture section.

The WunderGraph Stack

WunderGraph is made up of the three core components:

  • wunderctl: A command line tool to create, deploy and manage your WunderGraph application.
  • SDK: Auto-generated and type-safe client to configure and interact with your WunderGraph.
  • WunderHub The Package Manager for APIs that allows you to share and integrate your API’s in a few clicks.

The auto-generated type-safe client can be used in any Node.js or TypeScript backend application (including serverless applications and microservices).

Core features

  • Unified Graph: Combine all your data sources into a unified GraphQL Schema.
  • JSON-RPC: Expose GraphQL operations through JSON-RPC. Learn more about this design choice.
  • Type-Safe Clients: Auto generate custom type-safe API Clients with Authentication / Authorization and file upload support.
  • Customizable: Customizable gateway logic with TypeScript.
  • Standards: Build upon standards like GraphQL, OpenAPI, OAuth2, S3…
  • Open Source: 100% Open Source, No vendor lock-in.
  • Community: First-class support for frameworks like Next.js, React, Svelte…

Note: WunderHub is our vision of the Package Manager for APIs. Like npm, but for APIs. Sign up for free!

How does WunderGraph work

This section provides a high-level overview of how WunderGraph works and its most consumer centric components. For a more thorough introduction, visit the architecture documentation.

After initializing your first WunderGraph application with npx @wundergraph/wunderctl init, you have a NPM package and a .wundergraph folder. This folder contains the following files:

  • wundergraph.config.ts – The primary config file for your WunderGraph application. Add data-sources and more.
  • wundergraph.operations.ts – Configure authentication, caching and more for a specific or all operations.
  • wundergraph.server.ts – The hooks server to hook into different lifecycle events of your gateway.

After configuring your data-sources, you can start writing operations. An operation is just a *.graphql file. The name of the file will be the operation name. You can write queries, mutations and subscriptions that spans multiple data-sources. Each operation will be exposed securely via HTTP JSON-API through the WunderGraph gateway. After writing your operations, you can start deploying your WunderGraph application.
