The Missing Piece in Node.js Configuration

Node.js introduced the --experimental-config-file flag over a year ago, enabling support for node.config.json. What started as an experiment has quietly evolved into one of the most important shifts in how we configure and run Node.js applications.

In this talk, we’ll look back at what this feature unlocked in practice: fine-grained runtime control, improved security, and a more predictable execution model across environments.

Finally, we’ll discuss what it means for node.config.json to move toward stability, and how it could reshape the broader ecosystem by becoming a standard way to configure Node.js runtimes.
