There are many interesting new Initiatives to bring new Features to TYPO3 V10. In this Article I want to show how to use TYPO3 with GraphQL and then, how to use it with Apollo's help in React JS.
The GraphQL Schema is generated from the TCA an all fields from there can be queried.
There is one more Initiative: https://github.com/TYPO3-Initiatives/security
It brings Access control to limit the fields that Users can query from your GraphQL Endpoint.
