WunderGraph merges all DataSources into one unified "virtual Graph" which you can then securely expose as a JSON API by writing GraphQL Operations. GraphQL as an ORM to your APIs, an API Orchestration Layer.Ĭurrently, you can use REST, GraphQL, Apollo Federation (with Subscriptions), PostgreSQL and MySQL as a DataSource for your WunderGraph application. The approach described above is the fastest way to implement a Backend For Frontend (BFF) on the fly.Ĭombine it with the capability to add any number of DataSources and upstream protocols, and we're turning GraphQL into way more than just a Query Language. I don't see GraphQL as a simple Query Language where you build a server, add a client and call it a day. That's what we do automatically, so let's have a look at the generated JSON-Schemas!Īs we've discussed, adding a JSON API with JSON-Schema in front of your GraphQL API has a lot of benefits, but there's more to it. We can create a JSON-Schema for the input and the response! If we know the JSON structure, we can even go one step further. The graphql-js implementation has an excellent visitor implementation which makes this quite easy. If we walk through the AST of this GraphQL Operation, we're able to extract the exact JSON structure of both input and response. WunderGraph does this de-inlining by default which brings us to an important conclusion.Ī Persisted GraphQL Operation is a function that takes a JSON Object and returns a JSON Object.Ī function with this specification is actually very useful! If we're de-inlining all GraphQL Variables, they "must" be supplied as a JSON Object. GraphQL Variables can either be supplied "inline", meaning, as part of the GraphQL Operation / Document. Both, input and response can be expressed as a JSON Object.įor the response, it's obvious. It's one of my favorite examples because it contains so many cool features.Īs you can see, it's a function that takes an input and returns a response. Let's have a look at a GraphQL Operation to make things clearer. So, a persisted GraphQL Operation is a function that optionally takes a few arguments and returns a JSON Object. most applications don't change the Operations at runtime.you can still supply variables, just not change the content.they are like stored procedures or prepared statements.Sorry for the backlinking intermission, seo hacks.Īlright, a few facts about persisted GraphQL Operations. So here I am, writing a shorter one with a bit more focus. The problem is, I've realised that this blog post was a bit too long. In this post, I've listed 13 GraphQL security vulnerabilities and how Persisted Operations help solving them.įinally, I've wrote extensively about the Fusion of GraphQL, REST, JSON-Schema and HTTP2. Another time, I was talking about what happens if we treat the GraphQL Operation as the API schema. Additionally, Persisted Operations help a lot with Versioning and keeping APIs backwards compatible. I keep writing about this topic, for example I think that GraphQL is not meant to be exposed over the internet. I don't believe that GraphQL servers should directly expose their API. Let's do it!Īs some might know, I'm the biggest fan of Persisted GraphQL Operations. Implementing GraphQL servers and using GraphQL clients to query them is becoming boring, isn't it? How about trying something new? How about doing a crossover between OpenAPI, JSON-Schema and GraphQL? ![]() Today, I'd like to show you an unusual use case for the Query language: Building JSON APIs with JSON-Schema validation. GraphQL is known as a Query Language to Query Graphs. ![]()
