my-project

This project was bootstrapped by create-neon.

Building my-project

Building my-project 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 my-project

After building my-project, you can explore its exports at the Node console:

$ npm i
$ npm run build
$ node
> require('.').greeting('node')
{ 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.
