TypeScript Operations Reference
Here's a simplified overview of the WunderGraph architecture.
When defining TypeScript Operations, these are running on the server, meaning that they are protected from the public internet by the WunderGraph Gateway.
Authentication
The WunderGraph Gateway runs a few middlewares before allowing the request to reach the server. E.g. if you're using cookie-based or token-based authentication, the WunderGraph Gateway will verify that the user is authenticated. If an operation requires authentication, you can be sure that the request will never reach the server if the user is not authenticated.
JSON Schema Validation
Another important aspect is input validation. TypeScript Operations allow you to define the input schema using the zod
library. During development, WunderGraph generated a JSON Schema from the TypeScript Operation input schema. The WunderGraph Gateway will validate the request against this JSON Schema before passing it to the server.
This means, that if you're using TypeScript Operations, you don't have to worry about input validation. Define an input schema using zod
and you can trust that the request will be validated before reaching the server.
