Dummu - Performance in GraphQL

The fastest code is code that never runs at all, so start by cutting the unnecessary work.

Why this matters for GraphQL

This is a bold claim, an italic aside, and an underlined point, all in one GraphQL example.

What it touches:

• The GraphQL runtime or interpreter
• Whatever calls the code around it
• Anyone reading this six months from now

How to apply it:

1. Read the snippet below once, slowly.
2. Try changing one value and predict the output before running it.
3. Compare your prediction against what actually happens.

"Measure before and after. A change that feels faster is not the same as a change that is faster."

query GetUser($id: ID!) {
  user(id: $id) {
    name
    email
  }
}
