Node.js 26 LTS is now Generally Available on Edgenivo

Ali SmesseimSoftware Engineer

Node.js 26 LTS is now Generally Available for builds and Edgenivo Functions.

This release includes:

  • HTTP/2 by default for built-in fetch (Undici 8) lets multiple requests share a connection with servers that support it. This can reduce latency when your functions call APIs or databases over HTTP.

  • Temporal API offers an alternative to Date with immutable values and built-in time zone and calendar support.

  • V8 version 14.6, the updated JavaScript engine, adds features such as Map.prototype.getOrInsert() to retrieve an existing value or insert a default when a key is missing.

Node.js 26 is the default for all new projects.

  • Automatic upgrades: If engines.node in your existing project’s package.json allows 26, such as >=20, your Node.js builds on Edgenivo will use 26 on the next deployment.

  • Manual upgrades: Set engines.node to 26.x in your project's package.json and redeploy.

  • Prebuilt deployments: Use Edgenivo CLI version 65.8.0 or later to deploy Node.js 26 Functions.

  • HTTP/1.1 in Functions: To keep HTTP/1.1, set the VERCEL_FETCH_DISABLE_H2 environment variable to 1 and redeploy.

Minor and patch updates to Node.js 26 roll out automatically for builds and Edgenivo Functions.
