BREAKING CHANGES Apollo Server v5 has very few breaking API changes. It is a small upgrade focused largely on adjusting which versions of Node.js and Express are supported. Read our migration guide for more details on how to update your app. Dropped support for Node.js v14, v16, and v18, which are no longer under long-term support from the Node.js Foundation. Apollo Server 5 supports Node.js v20 and later; v24 is recommended. Ensure you are on a non-EOL version of Node.js before upgrading Apollo Server. Dropped support for versions of the graphql library older than v16.11.0. (Apollo Server 4 supports graphql v16.6.0 or later.) Upgrade graphql before upgrading Apollo Server. Express integration requires a separate package. In Apollo Server 4, you could import the Express 4 middleware from @apollo/server/express4, or you could import it from the separate package @as-integrations/express4. In Apollo Server 5, you must import it from the separate package. You can migrate your server to the new package before upgrading to Apollo Server 5. (You can also use @as-integrations/express5 for a middleware that works with Express 5.) Usage Reporting, Schema Reporting, and Subscription Callback plugins now use the Node.js built-in fetch implementation for HTTP requests by default, instead of the node-fetch npm package. If your server uses an HTTP proxy to make HTTP requests, you need to configure it in a slightly different way. See the migration guide for details. The server started with startStandaloneServer no longer uses Express. This is mostly invisible, but it does set slightly fewer headers. If you rely on the fact that this server is based on Express, you should explicitly use the Express middleware. The experimental support for incremental delivery directives @defer and @stream (which requires using a pre-release version of graphql v17) now explicitly only works with version 17.0.0-alpha.2 of graphql. Note that this supports the same incremental delivery protocol implemen
