Depsane NPM | npm.io

depsane

Checks for missing dependencies based on code reachable from the main entrypoint specified in package.json (defaults: index.js). Furthermore: if a bin-object is specified in package.json all code reachable from those files will also be included.

depsane is focused on determining which dependencies that should be present specifically in dependencies and devDependencies. It classifies a dependency found in devDependencies used in the main code path as missing, and a dependency only used as a devDependency but that is specified in dependencies is considered missing.

This solves the problem where an application works fine locally and during testing but fails once deployed as the deployed version will only be installed with its' dependencies but during testing and development both devDependencies and dependencies are installed.

There is also some experimental heuristics implemented to determine if mocha or eslint and their associated plugins are used as devDependencies or not.

Installation

npm install --save-dev depsane

Usage

npx depsane [directory] [arguments]

Prints missing dependencies and unused dependencies.

Exits with code 0 if no missing or unused dependencies are found and 1 otherwise.

The directory defaults to the current directory.

All of the arguments are optional:

--ignore-dirs: comma-separated list of dirs to ignore.

--ignores: comma-separated list of dependencies to ignore, supports wildcards (i.e. "eslint*" will ignore all dependencies that starts with eslint).
