MongoDB is adopting a formal schedule governing which versions of Node.js the MongoDB Node.js Driver supports. As of today, the driver is compatible with Node.js versions 4, 6, 8 and 10. This new schedule will align with the Node.js release schedule, ensuring that the full breadth of supported Node.js releases can be used with MongoDB.
Under the new compatibility schedule, the driver will be compatible with Node.js versions during active LTS dates and for 6 months past the End-of-Life date, as stated
here, for each version of Node.js. Given this new schedule and that Node.js v4 was marked End-of-Life on 04/30/2018, the next major release of the MongoDB Node.js Driver will no longer be compatible with version 4.x of Node.js.
