# Mutation
The mutation is a lot like the query. However, the mutation will not cache any results locally.
# Initializing a new Mutation
Mutations are created through the Buoy
-service. Buoy returns a Promise.
The mutation is executed immediately once initialized.

export class AppComponent {
constructor(
private buoy: Buoy
) { }
public createMovie(): void {
this.buoy.mutate(
// Mutation
gql `

console.log('Movie was created:', success);
