ostap

CLI tool that fast checks if your bundle contains multiple versions of the same package, only by looking in package.json.

Advantages:

faster than alternatives, since it doesn't require rebuilding the bundle (example, duplicate-package-checker-webpack-plugin);
uses only package.json;
suggests optimal package versions; see how
you can quickly see all the current versions of the same package that are used in the current bundle. see how

Quick start

npm i -g ostap

# create package.json if not exists
echo "{\"name\":\"demo-project\",\"version\":\"1.0.0\",\"dependencies\":{\"@nivo/bar\":\"0.54.0\",\"@nivo/core\":\"0.53.0\",\"@nivo/pie\":\"0.54.0\",\"@nivo/stream\":\"0.54.0\"}}" > ./package.json

ostap ./package.json -s

How to use

{
  "name": "demo-project",
  "version": "1.0.0",
  "dependencies": {
    "@nivo/bar": "0.54.0",
    "@nivo/core": "0.53.0",
    "@nivo/pie": "0.54.0",
    "@nivo/stream": "0.54.0"
