Robespierre is a tool built in RUST and packaged via NPM that helps you find extraneous and implicit dependencies by comparing your manifest and actual imports in your typescript code using AST parsing.

• An extraneous dependency is a dependency declared in you package.json manifest, but unused in you code
• An implicit dependency is the opposite. A dependecy used somewhere in your codebase via an import statement, but not declared in your package.json. It can work somehow, 'cause it's installed indirectly by another dependency, but this is a bad practice.

Robespierre is focused on performance and uses SWC typescript AST parser to browse your codebase efficiently.

The name "robespierre" is a humorous reference to Maximilien de Robespierre, a significant political figure in the French Revolution. Known for prolifically using the guillotine, our binary borrows its name because it helps you figure out which dependency's head to cut off!

🦀 Build

You can build the Robespierre Rust executable yourself, therefore you will need a working Rust and Cargo setup.

In order to compile for your native platform, just run:

cargo build --release

📦 Packaging

You can then wrap the binary manually

export BUILD_OS=drawin
export BUILD_ARCH=arm64
export BUILD_NAME="${BUILD_OS}-${BUILD_ARCH}"
export BUILD_VERSION=1.0.12
export BUILD_TARGET=/path/to/compiled/robespierre

./package.sh

🚀 Release

To publish a new version on NPM use the script to version and tag to trigger a Github workflow.

export RELEASE_VERSION=1.0.12
sh ./version.sh ${RELEASE_VERSION}
git commit -am"chore: publish ${RELEASE_VERSION} :tada:"

When merged on main branch, the version will be published on NPM and git tag will be created
