Built-in plugins


Plugins extend 's functionality by performing custom in response to certain events. These events correspond to individual phases of the request lifecycle, and to the lifecycle of Apollo Server itself.

Certain features are provided as built-in plugins that are exported from within the @apollo/server package. installs certain plugins automatically, but you can also install them manually to override their default settings. See each plugin's documentation for details.

You can also create custom plugins.

import { ApolloServer } from "@apollo/server";
import { ApolloServerPluginUsageReporting } from '@apollo/server/plugin/usageReporting';
const server = new ApolloServer({
typeDefs,
resolvers,
