chain

Return a resolver that is the sum of the ones in the supplied array. The execution order follows the order from left to right. The last resolver being the one to return the final expect value. chain([1, 2, 3, 4])

import { chain } from 'graphql-resolved';
import { isAuthenticated, isAdmin, isTopContributer } from './auth/resolvers';
import * as UserResolvers from './user/resolvers';

const getMe = chain([isAuthenticated, UserResolvers.getMe])

const Query = {
  getMe
}

const resolvers = {
  Query,
}

apply

Applies a list of resolvers to each of those supplied by the to object.

• resolvers The execution order follows the order from left to right.

const allUserResolvers = apply({ resolvers: [isAuthenticated], to: UserResolvers })
const Query = {
  ...allUserResolvers
}

protect

The protect key work take three arguments:

• it (Optional) a resolver function, if supplied protect returns a new resolver function
• all(Optional) a map of resolvers, if supplied protect returns an object with the exact same resolvers names as keys
• using a list of resolvers to apply(The order matters from left to right).

const getMe = protect({
  it: UserResolvers.getMe,
  using: [isAuthenticated]
});

const adminResolvers = protect({
  all: { PostResolvers.deletePost, PostResolvers.correctPost },
