![]() Stores data locally for the last JSON Formatted in Browser's Local Storage.Supports JSON Graph View of JSON String which works as JSON debugger or corrector and can format Array and Object. ![]() 95% of API Uses JSON to transfer data between client and server.This functionality helps to format json file. JSON File Formatter provides functionality to upload JSON file and download formatted JSON File.It's also a JSON Beautifier that supports indentation levels: 2 spaces, 3 spaces, and 4 spaces.It's the only JSON tool that shows the image on hover on Image URL in a tree view.It helps to validate JSON online with Error Messages.It also provides a tree view that helps to navigate your formatted JSON data. change PostgreSQL with MySQL, switch from a REST to a gRPC API, etc., all without breaking the JSON API contract.JSON Formatter and JSON Validator help to auto format JSON and validate your JSON text. In the future, you'll be able to easily swap out DataSources, e.g. This allows us to decouple API consumers from the DataSources itself. just using generated GraphQL APIs, we're adding an abstraction layer, the JSON API. 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.
