depchecka v1.0.2

depchecka

A simple node.js script for finding unused dependencies that are in your package.json.

depchecka will load the list of dependencies from the package.json file found in the current working directory and then recursively traverse the directory tree starting at the specified directory path, processing all javascript files (.js, .jsx, .ts, .tsx, .astro, .svelte), looking for use of those dependencies. The list of unused dependencies is shown on completion.

NOTE: Some frameworks may include dependencies in package.json that may be listed as unused by this tool. Also, if you have installed dev dependencies as regular dependencies these may also be listed as unused.

Usage

From the root of your project (where the main package.json lives) run:

npx depchecka ./path/to/entry-point

./path/to/entry-point should be your source directory or where you want depchecka to start recursively looking for dependencies used (defaults to ./src).

Example

➜ npx depchecka ./src
Processed 1288 files in 496ms

Unused deps: {
  '@material-ui/lab': '4.0.0-alpha.60',
