Most of this document is concerned with _implementing_ schema directives, and some of the examples may seem quite complicated. No matter how many tools and best practices you have at your disposal, it can be difficult to implement a non-trivial schema directive in a reliable, reusable way. Exhaustive testing is essential, and using a typed language like TypeScript is recommended, because there are so many different schema types to worry about.

However, the API we provide for _using_ a schema directive is extremely simple. Just import the implementation of the directive, then pass it to `makeExecutableSchema` via the `directives` argument, which is an object that maps directive names to directive implementations:

Note that a subclass of `SchemaDirectiveVisitor` may be instantiated multiple times to visit multiple different occurrences of the `@deprecated` directive. That's why you provide a class rather than an instance of that class.

If for some reason you have a schema that uses another name for the `@deprecated` directive, but you want to use the same implementation, you can! The same `DeprecatedDirective` class can be passed with a different name, simply by changing its key in the `directives` object passed to `makeExecutableSchema`. In other words, `SchemaDirectiveVisitor` implementations are effectively anonymous, so it's up to whoever uses them to assign names to them.
