Question: Optional config param for the hapi register method

[developer-rakeshpaul]

Overview of the Issue

Team is it possible to provide an optional config param to the register method of the hapi plugin. This will help users with ability to configure authentication mode and other params easily. For instance if we change the register method for the hapi plugin like below

const plugin = {
  register: (server, { graphiql = true, context = {}, config = {}, schema = required() } = {}, next) => {
    const handler = (request, reply) => {
      const data = request.payload || request.query || {};
      const { query, variables } = data;

      if (accepts(request, 'html') && graphiql) {
        return reply(renderGraphiQL({ query, variables }));
      }

      if (query && query.includes('mutation') && isGet(request)) {
        return reply(methodNotAllowed('GraphQL mutation only allowed in POST request.'));
      }

      let parsedVariables = variables;
      try {
        parsedVariables = JSON.parse(variables);
      } catch (err) {
        // ignore
      }

      return graphql(schema, query, { request }, context, parsedVariables)
        .then((result) => {
          if (result.errors) {
            const message = result.errors.map((error) => error.message).join('\n');
            reply(badRequest(message));
            return;
          }

          reply(result);
        })
        .catch((err) => {
          reply(badRequest(err));
        });
    };

    server.route({
      method: 'POST',
      path: '/graphql',
      config,
      handler
    });

    if (graphiql) {
      server.route({
        method: 'GET',
        path: '/graphql',
        config,
        handler
      });
    }

    next();
  }
};

Then users can easily provide authentication and security by providing the auth mode in the config like below without going for the resolve hooks

{
    register: graffiti.hapi,
    options: {
      schema,
      context: {}, // custom context
      config: {
        description: 'graphQL endpoints',
        auth: 'jwt',
      },
    },
  }

Please help if there are any better ways to solve this.

Kind Regards,

Hey @developer-rakeshpaul,
I don't really use hapi, but it looks alright. Can you open a PR? 😉
