Follow-along: Schema publish

Follow-along: Schema publish

Goal: Finish the process of making changes to the supergraph by publishing the updated schema.

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 \
--schema schema.graphql \
--name recipes
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!
Navigate to the Launches page. Click on the latest launch in the list.

Let's try running the same query from last time.
query GetRecipeTimes {
randomRecipe {
name
prepTime
}
}
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!
