Issues

Node.js comes with V8 14.6 and some breaking changes. There asre two PRs to support Node.js on Nan and node-gyp:

• support Node.js v26 nodejs/nan#1016
• support Node.js 26 nodejs/node-gyp#3311

Also yargs v17 also not compatible with v26

Let's wait for the v26 fixes

Currently the prebuilds are not working:

This seems to be due to NAN (Native Abstractions for Node.js) not supporting Node.js v26 yet. See: https://github.com/nodejs/nan#native-abstractions-for-nodejs

The current NAN version 2.26.2 only supports Node.js up to version 25. Node.js v26 introduced breaking changes in the V8 API that are incompatible with NAN.
Prebuilds for Node.js v26 cannot be generated until NAN releases v26 support or we migrate to node-addon-api (N-API)

The gc-stats also filing on npm install step, because of the nan.

I've created an issue here nodejs/nan#1017
