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 functionall
(Optional) a map of resolvers, if supplied protect
returns an object with the exact same resolvers names as keysusing
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 },
using: [isAuthenticated, isAdmin]
});
const Query = {
getMe
...adminResolvers
}
