Repository used by the Node-API team to manage work related to Node-API and node-addon-api
Node.js API (Node-API)
This repository is the home for ABI Stable Node API project Node-API which was previously known as N-API.
The goal of this project is to provide a stable Node API for native module developers. Node-API aims to provide ABI compatibility guarantees across different Node versions and also across different Node VMs - allowing Node-API enabled native modules to just work across different versions and flavors of Node.js without recompilations.
It is introduced by this Node enhancement proposal: 005-ABI-Stable-Module-API.md.
Node-API is part of Node.js core. Documentation is available here: https://nodejs.org/docs/latest/api/n-api.html.
Node.js versions 8.12.0 and above provide Node-API as a stable feature.
Branches
Currently this repo is being used only for meta issue management and future planning by the Node-API team.
API Design & Shape
The current shape of the API can be found in header file node_api.h. Full documentation is available as part of the standard Node.js API docs here: https://nodejs.org/docs/latest/api/n-api.html.
There is also a header-only C++ API, which simplifies development while still using the same ABI-stable Node API underneath. It is distributed as a separate npm package: https://www.npmjs.com/package/node-addon-api.

Testing
In addition to running the tests in the converted modules we also have a converted version of the NAN examples node-addon-examples
How to get involved
- Convert a native module to use Node-API and report issues on conversion and performance;
- Port ABI stable APIs to your fork of Node and let us know if there are gaps;
- Review the roadmap and see how you can help accelerate this project.
Badges
The use of badges is recommended to indicate the minimum version of Node-API required for the module. This helps to determine which Node.js major versions are supported. Addon maintainers can consult the Node-API support matrix to determine which Node.js versions provide a given Node-API version. The following badges are available:
Meeting
The team meets once a week on zoom. See the Node.js Calendar for the current time/day of the week. The link to participate to the meeting is: https://zoom.us/j/363665824 .
