Workers – Node.js 24 is now the default for Workers Builds

Workers Builds now uses Node.js 24.18.0 by default. The build image preinstalls Node.js 22.23.2 and 24.18.0.

You can continue to override the default with the NODE_VERSION environment variable, an .nvmrc file, or a .node-version file. For more information, refer to Override default versions.
