Follow-along: Schema publish

1. In a terminal window, paste in the rover subgraph publish command. Make sure you replace the parameters with your own values.

   rover subgraph publish poetic-plates-supergraph@main \
     --name recipes \
     --schema schema.graphql

   Copy

   If all goes well, we should see the terminal output with a message confirming that the subgraph has been published and the supergraph has been updated!

2. Navigate to the Launches page. Click on the latest launch in the list.

   https://studio.apollographql.com

   

3. Let's try running the same query from last time.

   query GetRecipeTimes {
     randomRecipe {
       name
       prepTime
     }
   }

   Copy

   The query still runs and comes back successfully, but we get a warning in the Explorer (that yellow squiggly line!) that prepTime has been deprecated and not to use it anymore.

Our launch was successful! 🎉 We've made changes to our supergraph!
