Meteor 3.0 Migration Helped Rocket.Chat Move Off End-of-Life Node.js Runtime

The report explains how Meteor.js relied on node-fibers, which blocked upgrades from EOL Node.js 14, and describes the multi-year, staged migration culminating in Meteor 3.0 (July 2024) and Rocket.Chat’s move to Node.js 20 (November 2024). It frames this as a supply-chain and operational risk example — unsupported runtimes can create audit and exposure issues across sensitive downstream environments even when no CVE or active exploit exists — and credits the public roadmap, staged changes, and direct coordination with downstream consumers for making the transition manageable.
