# 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](https://github.com/darrenscerri/duplicate-package-checker-webpack-plugin));

* uses only package.json;

* suggests optimal package versions; [see how](#for-suggests-optimal-package-versions)

* you can quickly see all the current versions of the same package that are used in the current bundle. [see how](#for-see-all-the-current-versions-of-the-same-package-that-are-used-in-the-current-bundle)

## Quick start
```
# 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

npx ostap ./package.json -s
```

## How to use

For example, you have `package.json`:
```
{
"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"
}
}
```
### For suggests optimal package versions

```
ostap ./package.json
```

### For see all the current versions of the same package that are used in the current bundle

```
ostap ./package.json -s
```

### Installation
```
npm i -g ostap
```
### Options
```
Options:
-c, --use-cache Use cache
-d, --duplicates Show duplicates in source and optimal tree
