# @push.rocks/smartnpm
interface with npm to retrieve package information

## Install
To install `@push.rocks/smartnpm`, open your terminal and run the following command:
```sh
npm install @push.rocks/smartnpm --save
```
This will add `@push.rocks/smartnpm` as a dependency to your project and you're ready to start using it.

## Usage
To use `@push.rocks/smartnpm` in your project, you first need to import it in your TypeScript files. `@push.rocks/smartnpm` provides a powerful interface to interact with npm to retrieve package information, handle package downloads, and more. Below are examples showcasing how to leverage some of its features in real-world scenarios.

### Initialize the NpmRegistry
Before you can retrieve any package information or perform actions such as downloading packages, you need to create an instance of `NpmRegistry`. This acts as your starting point.

```typescript
import { NpmRegistry } from '@push.rocks/smartnpm';

const npmRegistry = new NpmRegistry();
```

Optionally, you can provide a custom npm registry URL if you're not using the default npm registry:

```typescript
const customRegistry = new NpmRegistry({
  npmRegistryUrl: 'https://custom.registry.url'
});
```

### Retrieve Package Information
`@push.rocks/smartnpm` allows you to easily get detailed information about a package, including its versions, dist tags, and metadata. Here's how you can get information about a specific package:

```typescript
async function getPackageInfo() {
  const packageName = 'your-package-name';
  const packageInfo = await npmRegistry.getPackageInfo(packageName);
  console.log(packageInfo);
}

getPackageInfo();
```

### Search for Packages
You can search for packages using a variety of filters such as keywords, author, maintainer, etc. Here's an example of searching for packages with specific criteria:

```typescript
async function searchPackages() {
  const searchResults = await npmRegistry.searchOnNpm({
    keywords: ['webpack-plugin'],
    author: 'webpack'
  });
  console.log(searchResults);
}

searchPackages();
```

### Downloading Packages
`@push.rocks/smartnpm` provides an easy way to download npm packages and extract them to a specific directory. This could be useful for creating tools that need to programmatically handle packages.

```typescript
async function downloadPackage() {
  const packageName = 'some-package';
  const targetDirectory = './path/to/targetDir';

  await npmRegistry.savePackageToDisk(packageName, targetDirectory);
  console.log(`${packageName} has been downloaded to ${targetDirectory}`);
}

downloadPackage();
```

### Working with Package Versions and Dist Tags
You can easily retrieve detailed information about specific package versions or distribution tags. This is particularly useful for automation scripts that need to work with specific versions of a package.

```typescript
async function getPackageVersionDetails() {
  const packageName = 'some-package';
  const version = '1.0.0'; // You can also use dist tags like 'latest'

  const packageInfo = await npmRegistry.getPackageInfo(packageName);
  const versionInfo = packageInfo.allVersions.find(v => v.version === version);
  console.log(versionInfo);
}

getPackageVersionDetails();
```

These examples only scratch the surface of what you can achieve with `@push.rocks/smartnpm`. By integrating this library, you have a powerful tool at your disposal for interacting with npm in a programmatic way, enabling a wide range of possibilities for automation, CI/CD, and tooling around npm packages.
