手把手教程：
cd ./node_modules/demo-cmtjs-neon
node ./test.js
node ./lib/1.cjs
node ./lib/1.mjs
cd ../..
回到了根目录，创建js分别去测试require和import，了解会导入什么，核心能力是js和全平台兼容及使用rust写底层能力

这个项目很好的展示了如何兼容多种情况灵活导入：cjs mjs cts mts。虽然我建议js就走mjs路线，但还有不少资源使用其他方式写的；而此项目展示了精简核心，掌握就能更好理解其它所有类型配置。另附对rust构建底层的启蒙学习。处理这些协议问题，真是没什么获得感，做好记录，快速理清就好

使用neon的话，安装好rust cargo,跨linux平台安装cross docker，学会看package.json，找到相应指令build

创建新neon项目：npm create neon XXX ,当前平台使用选app即可（简单高效），需要全面兼容跨平台选lib（配置也会复杂的多，当前项目即是）

demo-cmtjs-neon

This project was bootstrapped by create-neon.

Building demo-cmtjs-neon

Building demo-cmtjs-neon requires a supported version of Node and Rust.

To run the build, run:

$ npm run build

This command uses the @neon-rs/cli utility to assemble the binary Node addon from the output of cargo.

Exploring demo-cmtjs-neon

After building demo-cmtjs-neon, you can explore its exports at the Node console:

$ npm i
$ npm run build
$ node
> require('.').greeting()
{ message: 'hello node' }

Available Scripts

In the project directory, you can run:

npm run build

Builds the Node addon (index.node) from source, generating a release build with cargo --release.

Additional cargo build arguments may be passed to npm run build and similar commands. For example, to enable a cargo feature:

npm run build -- --feature=beetle

npm run debug

Similar to npm run build but generates a debug build with cargo.

npm run cross

Similar to npm run build but uses cross-rs to cross-compile for another platform. Use the CARGO_BUILD_TARGET environment variable to select the build target.

npm run release

Initiate a full build and publication of a new patch release of this library via GitHub Actions.

npm run dryrun

Initiate a dry run of a patch release of this library via GitHub Actions. This performs a full build but does not publish the final result.

npm test

Runs the unit tests by calling cargo test. You can learn more about adding tests to your Rust code from the Rust book.
