Ability

Build

After yarn build/npm run build command, you can see index.[darwin|win32|linux].node file in project root. This is the native addon built from lib.rs.

Test

With ava, run yarn test/npm run test to testing native addon. You can also switch to another testing framework if you want.

CI

With github actions, every commits and pull request will be built and tested automatically in [node@10, node@12, @node14] x [macOS, Linux, Windows] matrix. You will never be afraid of the native addon broken in these platforms.

Release

Release native package is very difficult in old days. Native packages may ask developers who use its to install build toolchains like gcc/llvm , node-gyp or something more.

With Github actions, we can easily prebuild binary for major platforms. And with N-API, we should never afraid of ABI Compatible.

The other problem is how to deliver prebuild binary to users. Download it in postinstall script is a common way which most packages do it right now. The problem of this solution is it introduced many other packages to download binary which has not been used by runtime codes. The other problem is some user may not easily download the binary from github/CDN if they are behind private network (But in most case, they have a private NPM mirror).

In this package we choose a better way to solve this problem. We release different npm packages for different platform. And add it to optionalDependencies before release the Major package to npm.

NPM will choose which native package should download from registry automatically. You can see npm dir for details. And you can also run yarn add @napi-rs/package-template to see how it works.

Develop requirements

• Install latest Rust
• Install NodeJS@10+ which fully supported N-API
• Install yarn@1.x

Test in local

• yarn
• yarn build
• yarn test

And you will see:

$ ava --verbose

  ✔ sync function from native code
  ✔ sleep function from native code (201ms)
