Readme
A GraphQL Relay connection with custom cursor functions. Can be used for MongoDB, Mongoose, plain objects, scalars, or any data formats.
npm install --save graphql-relay-connection
mongooseConnection
is predefined for you.
For other usage, scroll down to Custom connection
section below.
import {
connectionDefinitions,
connectionArgs,
} from 'graphql-relay';
import {mongooseConnection} from 'graphql-relay-connection';
const {
connectionFromPromisedArray,
cursorToDocument,
} = mongooseConnection;
const UserType = new GraphQLObjectType({
name: 'User',
fields: () => ({
friends: {
type: UserConnection,
args: connectionArgs,
resolve: (user, args) => {
args.first = args.first || 10;
const doc = cursorToDocument(args.after);
const friends = User.find({
isFriendWith: user._id,
_id: {$gt: doc && doc._id},
})
.limit(args.first + 1) // add +1 for hasNextPage
.exec()
return connectionFromPromisedArray(friends, args);
},
},
}),
});
const {
connectionType: UserConnection,
} = connectionDefinitions({
nodeType: UserType,
});
Simply provide { comparableToCursor, cursorToComparable, comparator }
to defineConnection
.
import defineConnection from 'graphql-relay-connection';
import {
base64,
unbase64,
} from './util';
const PREFIX = 'number:';
// Given a comparable value, return a string cursor.
function numberToCursor(num) {
return base64(PREFIX + num);
}
// Given a string cursor,
// return a comparable value for the comparator function.
function cursorToNumber(cursor) {
const num = parseInt(unbase64(cursor).substring(PREFIX.length), 10);
return isNaN(num) ? null : num;
}
// Sort function for array.sort().
// Given two values, return an interger.
function compareNumbers(num1, num2) {
return num1 - num2;
}
const {
connectionFromArray,
connectionFromPromisedArray,
} = defineConnection({
comparableToCursor: numberToCursor,
cursorToComparable: cursorToNumber,
comparator: compareNumbers,
});
import type {
ConnectionCursor,
} from './connectionTypes';
import defineConnection from './defineConnection';
import {
base64,
unbase64,
startsWith,
} from './util';
export type ID = string;
export type Document = {
id: ID,
};
const PREFIX = 'mongoose:';
function documentToCursor(doc: Document): ConnectionCursor {
return base64(PREFIX + doc.id);
}
function cursorToDocument(cursor: ConnectionCursor): ?Document {
const unbased = unbase64(cursor);
if (startsWith(unbased, PREFIX)) {
const id = unbased.substring(PREFIX.length);
if (id) return {id};
}
return null;
}
function compareDocuments(doc1: Document, doc2: Document): number {
if (doc1.id < doc2.id) {
return -1;
}
if (doc1.id > doc2.id) {
return 1;
}
return 0;
}
const {
connectionFromArray,
connectionFromPromisedArray,
} = defineConnection({
comparableToCursor: documentToCursor,
cursorToComparable: cursorToDocument,
comparator: compareDocuments,
});
export {
compareDocuments,
connectionFromArray,
connectionFromPromisedArray,
cursorToDocument,
documentToCursor,
};
