jseql-ffi

This project was bootstrapped by create-neon.

Building

Building 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

After building jseql-ffi, you can explore its exports at the Node console. CS_CLIENT_ID and CS_CLIENT_KEY must be set in your environment for the call to newClient() to succeed.

$ npm i
$ npm run build
$ node
> const addon = require(".");
> const client = await addon.newClient();
> const ciphertext = await addon.encrypt(client, "plaintext", "column_name");
> const plaintext = await addon.decrypt(client, ciphertext);
> console.log({ciphertext, plaintext});

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.

Entry	Purpose
`Cargo.toml`	The Cargo manifest file, which informs the `cargo` command.
`README.md`	This file.
`lib/`	The directory containing the generated output from tsc.
`src/`	The directory containing the TypeScript source files.
`index.mts`	Entry point for when this library is loaded via ESM `import` syntax.
`index.cts`	Entry point for when this library is loaded via CJS `require`.
`crates/`	The directory tree containing the Rust source code for the project.
`lib.rs`	Entry point for the Rust source code.
`platforms/`	The directory containing distributions of the binary addon backend for each platform supported by this library.
`package.json`	The npm manifest file, which informs the `npm` command.
`target/`	Binary artifacts generated by the Rust build.

Releasing

Releases are handled by GitHub Actions using a workflow_dispatch event trigger. The release workflow was generated by Neon.

The release workflow is responsible for:

Building and publishing the main @cipherstash/jseql-ffi package as well as the native packages for each platform (e.g. @cipherstash/jseql-ffi-darwin-arm64).
Creating the GitHub release.
Creating a Git tag for the version.

To perform a release:

Navigate to the "Release" workflow page in GitHub.
Click on "Run workflow".
Select the branch to release from. Use the default of "main" unless you want to do a pre-release version or dry run from a branch.
Select whether or not to do a dry run. Dry runs are useful for verifying that the build will succeed for all platforms before doing a full run with a publish.
Choose a version to publish. The options are similar to npm version. Select "custom" in the dropdown and fill in the "Custom version" text box if you want to use a semver string instead of the shorthand (patch, minor, major, etc.).
Click "Run workflow".

Note that we currently don't have any automation around release notes or a changelog. However, you can add release notes after running the workflow by editing the release on GitHub.
