FR - Middleware to log queries to a another repository

[rturk]

Feature request: Log queries to a database

1. Query text
2. Execution time
3. Date
4. Request source (IP, Auth code, etc)
5. Info about required nodes
6. Filter defines what queries will be logged or not

You can implement this with a query resolve hook.

Thanks. Including @sibeliusseraphini.
Maybe this should be implemented in the Graphql logic. Ideally any middleware logic ,such as logging, needs to be agnostic from the underling data source.
Comments?

@rturk Trust me, it's not so hard to implement these in resolve hooks:

const hooks = {
  plural: {
    pre: (next, root, args, context) => {
      context.rootValue.startTime = Date.now();
    },
    post: (next, value, args, asd, context) => {
      // 1) Query text
      const { query, variables } = context.rootValue.body // I need to add the body to rootValue in `graffiti`, you can open a PR too
      // 2) Execution time
      const executionTime = Date.now() - context.rootValue.startTime;
      // 3) Date
      const date = Date.now()
      // 4) Request source (IP, Auth code, etc)
      const { headers } = context.rootValue
      // 5) Info about required nodes
      const { fieldName, fieldASTs } = context
      // 6) Filter defines what queries will be logged or not
      if (/* custom filter */.filter(context)) {
        // save
      }
    }
  }
};
const schema = getSchema([/* models */], { hooks });
