title: apollo-link-dedup description: Deduplicate matching requests before making a request
NOTE This link is included by default when using apollo-client so you don't need to add it to your link chain if using apollo-client.
Installation
npm install apollo-link-dedup --save
Usage
import { DedupLink } from "apollo-link-dedup";
const link = new DedupLink();
Options
The Dedup Link does not take any options when creating the link.
Context
The Dedup Link can be overridden by using the context on a per operation basis:
forceFetch
: a true or false (defaults to false) to bypass deduplication per request
import { createHttpLink } from "apollo-link-http";
import ApolloClient from "apollo-client";
import InMemoryCache from "apollo-cache-inmemory";
const client = new ApolloClient({
link: createHttpLink({ uri: "/graphql" }),
cache: new InMemoryCache()
});
// a query with apollo-client that will not be deduped
client.query({
query: MY_QUERY,
context: {
forceFetch: true
}
})
