### Installing RSS.app Node.js Library

Source: https://github.com/rssapp/rssapp-api/blob/main/README.md

This snippet demonstrates how to install the `rss-generator-api` package using either npm or yarn. It's a prerequisite for using the library in your Node.js project.

```Shell
npm install rss-generator-api --save
# or
yarn add rss-generator-api
```

### Creating RSS Feed with TypeScript (Node.js)

Source: https://github.com/rssapp/rssapp-api/blob/main/README.md

This example illustrates how to use the RSS.app library with TypeScript, including type imports for `RssAppFeed`. It initializes the client and then creates a feed asynchronously, logging the feed's ID.

```TypeScript
import RssApp, { RssAppFeed } from 'rss-generator-api';
const rssApp = new RssApp({ apiKey: 'c_...', apiSecret: 's_...' });

const createFeed = async () => {
  const feed: RssAppFeed = await rssApp.feed.create({ url: 'https://bbc.com' });

  console.log(feed.id);
};
createFeed();
```

### Creating RSS Feed using CommonJS (Node.js)

Source: https://github.com/rssapp/rssapp-api/blob/main/README.md

This example shows how to initialize the RSS.app library using `require` and create a new RSS feed from a given URL. It uses promises to handle success and error cases, logging the feed object or any errors encountered.

```JavaScript
const RssApp = require('rss-generator-api');

const rssApp = new RssApp({ apiKey:  'c_...', apiSecret:  's_...' });

rssApp.feed
  .create({ url:  'https://bbc.com' })
  .then((feed) => {
     console.log('Success', feed);
  })
  .catch((err) => {
    console.log('Error', err);
  });
```

### Creating RSS Feed using ES Modules with Async/Await (Node.js)

Source: https://github.com/rssapp/rssapp-api/blob/main/README.md

This snippet demonstrates how to use the RSS.app library with ES modules and `async`/`await` syntax. It initializes the client with API keys and then asynchronously creates a new feed, logging its ID upon success.

```JavaScript
import RssApp from 'rss-generator-api';
const rssApp = new RssApp({ apiKey: 'c_...', apiSecret: 's_...' });

(async () => {
  const feed = await rssApp.feed.create({ url: 'https://bbc.com' });

  console.log(feed.id);
})();
```

### Chaining RSS.app API Calls with Promises (Node.js)

Source: https://github.com/rssapp/rssapp-api/blob/main/README.md

This snippet demonstrates how to chain multiple RSS.app API calls using promises. It first creates a new feed and then, upon successful creation, proceeds to list existing feeds in the account, handling potential errors at each step.

```JavaScript
// Create a new feed and then list all feeds in account:
rssApp.feed
  .create({
    url: 'https://bbc.com',
  })
  .then((feed) => {
    return rssApp.feed
      .list({
        limit: 10,
        offset: 0,
      })
      .then((res) => {
        console.log(res.data);
      })
      .catch((err) => {
        // Deal with an error
      });
  });
```
