Hi @shawnmclean I believe what you are looking for is schema federation. unfortunately, this is not supported by AppSync.
This plugin do support schema stitching though and you should be able to auto-merge schemas using glob patterns or by listing all your graphql schema files under schema
example:
custom:
appsync:
schema: schemas/*.graphql
or
custom:
appsync:
schema:
- userService.graphql
- orderService.graphql
if you are using a monorepo for all these services, this should be straightforward.
Regarding the request mappings, I am not sure what you meant. Do you also need to copy them? Do you have an example?
Thank you @bboure
Request mappings: I'm referring to Mapping Templates, like what's seen here: https://github.com/theburningmonk/appsyncmasterclass-backend/tree/main/mapping-templates
After I have the schema merged, is there a way to tell appsync to proxy a group of them to the downstream service without having to define individual mapping templates?
I have 2 AppSync services. These are separate packages with their own serverless.yml. For eg.
UserService
andOrderService
.I'd like to put an AppSync service in front of these 2. So I'll now have 3 serverless packages, with the new one being the proxy service.
I have this method lined up:
In the proxy service, I copy and paste the schema from the child services. This is tedious. I also need to update the request templates every time the schema changes in the child.
Is there a mechanism to combine all child schemas in the parent and set up the request templates via script?
Is this design still sensible? How can I achieve just the appsync to appsync section easily?
