The MySQL DataSource allows you to turn any MySQL protocol compatible Database into a secure production-grade GraphQL API. This includes AWS RDS, AWS Aurora, AWS Aurora Serverless, MySQL, MariaDB, Percona, and others.
Simply point WunderGraph to your Database, and we take care of all the heavy lifting.
No data gets exposed if you didn't explicitly allow it.
WunderGraph, by default, does NOT expose the generated (virtual) GraphQL API. To expose some functionality of the Graph, you have to write a Query or Mutation. The Query will be compiled into a secure RPC Endpoint.
With that in mind, it should be clear that clients are not able to modify Queries at runtime. All they can do is invoke the compiled RPC Endpoint.
Keeping Queries on the backend gives WunderGraph superpowers. If you look at the following Query, you'll see a custom
This directive does two things. First, it enforces that a user must be authenticated to be able to use this method. Second, we take the
name Claims of the user and inject them into the Mutation.
Claims are name value pairs of information about the authenticated user.
WunderGraph allows you to turn any GraphQL Query into a Live-Query. Live-Queries are regular Queries that automatically update the user interface. Data gets updated by polling the upstream DataSource continually using a predefined interval which you can configure.
Combined with a MySQL Database, you're able to easily build Realtime Applications like a Chat.
