Wrapping execute

[madsbuch]

I am trying to enable AuthZ for a yoga/pothos graphQL server running on Bun. For that I need to wrap the graphql execute function, but I don't find any exposed functionality to do that in yoga.

Is there a way to do that?

Alright, so this can be done making a custom plugin as the following:

const authZPlugin: Plugin = {
  onExecute(e) {
    const wrapped = wrapExecuteFn(e.executeFn, { rules }) as typeof e.executeFn;
    return wrapped(e.args);
  },
};

EDIT: This is how it is added:

const authZPlugin: Plugin = {
  onExecute({ executeFn, setExecuteFn }) {
    setExecuteFn(
      wrapExecuteFn(executeFn, {
        rules,
      })
    );
  },
};

And then adding it to the yoga plugins.

I moved away from this, as it does not at all play with the prisma realtions:

GraphQLError: undefined is not an object (evaluating 'state.fieldMap.relations')
 path: "..."
      at /.../node_modules/graphql/error/GraphQLError.js:91:9

ERR 86 |     var _this$nodes, _nodeLocations$, _ref;
87 | 
88 |     const { nodes, source, positions, path, originalError, extensions } =
89 |       toNormalizedOptions(rawArgs);
90 |     super(message);
91 |     this.name = 'GraphQLError';

Which is something I can't seem to fix within the resource bounds I have.

I hope this is useful to other people!

It seems you are using onExecute incorrectly;

onExecute({ executeFn, setExecuteFn }) {
  setExecuteFn(wrapExecuteFn(executeFn, ...opts));
}

You need to set the new execute fn with setExecuteFn instead of returning sth.

Thanks @ardatan! This definitely seems more right!

(However, it does not stop the error from occurring, The error occurs even though the custom yoga plugin is not added, so it indicates that it is something else than the execution life cycle.)

Maybe you can create a reproduction on CodeSandbox so we can help?
