feat: @envelop/on-resolve plugin for hooking into schema resolvers

[enisdenjo]

In light of the next release of envelop aiming to be engine agnostic, onResolverCalled must be no more because we can’t be wrapping the GraphQLSchema object.

To reduce migration friction and still have be able to hook onto schema resolvers, we introduce a new plugin called @envelop/on-resolve (debatable) that does exactly that.

Migration from onResolverCalled to { useOnResolve } from '@envelop/on-resolve'

*onResolverCalled signature stays exactly the same

import { envelop, Plugin } from '@envelop/core';
+ import { useOnResolve } from '@envelop/on-resolve';

import { onResolverCalled } from './my-resolver';

function useResolve(): Plugin {
  return {
-   onResolverCalled: onResolverCalled,
+   onPluginInit: ({ addPlugin }) => {
+     addPlugin(useOnResolve(onResolverCalled));
+   },
  };
}

const getEnveloped = envelop({
  plugins: [
    // ... other plugins ...
    useResolve(),
  ],
});

Things to note

• OnPluginInitHook now accepts a generic for the plugin context
• Refactored existing plugins using onPluginInit to respect the context generic
• onResolverCalled is no more

TODO

• Tests
• Integrate in @envelop/newrelic
