grapql rover and router workflow

 

To compose your supergraph, first we need to create individual schema for example product, review and user graphql schema. And we also need a supergraph.yaml first

subgraphs:

  product:

    routing_url: http://localhost:4001/graphql

    schema:

      file: ./product.graphql   # ← points AT the schema you already wrote

  user:

    routing_url: http://localhost:4002/graphql

    schema:

      file: ./user.graphql

  review:

    routing_url: http://localhost:4003/graphql

    schema:

      file: ./review.graphql

Let's create our supergraph 

rover supergraph compose --config ./supergraph.yaml > supergraph.graphql

If you're using powershell

rover supergraph compose --config ./supergraph.yaml | Out-File -Encoding utf8 supergraph.graphql

We will now have a combined supergraph schema that includes product, review and user graphql.

To perform checks we need to have graphos integration

rover subgraph check my-review@my-variant --schema ./review.graphql --name review

rover subgraph check my-product@my-variant --schema ./product.graphql --name product

rover subgraph check my-user@my-variant --schema ./user.graphql --name user

And it is time to run 

rover dev --supergraph-config ./supergraph.yaml

And then run it using router

# router.yaml

supergraph:

  listen: "0.0.0.0:4000"

  introspection: true

sandbox:

  enabled: true

homepage:

  enabled: false

include_subgraph_errors:

  all: true

c:\tools\router --config router.yaml --supergraph supergraph.graphql
