Graphql resolver cache
Easy wrapper around resolvers to cache results based on root elements and Graphql query arguments. Works best with Apollo Graphql.
Installation
$ npm install graphql-resolver-cache --saveConfiguration
Add a cache to your Graphql middleware:
import express from 'express';
import bodyParser from 'body-parser';
import { graphqlExpress } from 'apollo-server-express';
import { LruCache } from 'graphql-resolver-cache';
const myGraphQLSchema = // ... define or import your schema here!
const PORT = 3000;
const app = express();
const resolverCache = new LruCache();
// bodyParser is needed just for POST.
app.use('/graphql', bodyParser.json(), graphqlExpress({
schema: myGraphQLSchema,
context: { resolverCache }
}));
app.listen(PORT);Wrap your resolver in a cache function:
import { withCache } from 'graphql-resolver-cache';
export default {
User: {
getFriends: withCache((root, args, context) => { /* logic */ }),
},
};
