<h2 id='about'>About</h2>

`hotels-scraper-js` is a Node.js package designed to parse popular website hotels from a single module.

The package is [available on npm](https://www.npmjs.com/package/hotels-scraper-js) and can be installed and used in your Node.js project. It is used to scrape hotels list and hotel info from [Airbnb](https://www.airbnb.com/), [Booking](https://www.booking.com/), and [Hotels.com](https://hotels.com/) websites. Soon we planning to add Google Hotels or other websites.

The long-term plan of this project is to combine API and non-API solutions as [SerpApi started developing support for Google Hotels](https://github.com/serpapi/public-roadmap/issues/618) so later users can choose the desired backend to work with (free with limitations or paid without limitations). SerpApi's backend could be also useful for people who don't know how to use it, for example, SerpApi pagination which could be enabled with a simple function argument `pagination=True`.

Development is sponsored by [SerpApi](https://serpapi.com/).

<h3 id='problems'>Limitations and problems</h3>

- The main problem is that sites that parse often change their structure or selectors, so from time to time one of the scraping fields can't be gotten (sometimes the parser can crash).

- Hotels.com sometimes does not load the place input field (which happens in the usual browser too) and the place autocomplete doesn't work, so the parser can crash.

- If your IP address is blocked, or there is no access from your country, and if one of the sites from this parser doesn't work in your browser you can't get results from this parser.

You can get the installation guide and all available options from the [documentation](https://www.npmjs.com/package/hotels-scraper-js)

<h2 id='basic_examples'>Basic Examples</h2>

In these basic examples, we'll get links to each hotel from the 3 parsers. And then those links will be used to get hotel info.

### Airbnb hotels result from the selected category and with selected currency.

First, we need to get all available categories and currencies:

```javascript
console.log(airbnb.getFilters());
```

Output:

```json
{
   "currencies":[
      {
         "name":"Australian dollar",
         "value":"AUD"
      },
      {
         "name":"Brazilian real",
         "value":"BRL"
      },
    ... and other currencies
   ],
   "categories":[
      {
         "name":"A-frames",
         "value":"8148"
      },
      {
         "name":"Design",
         "value":"8528"
      },
     ... and other categories
   ]
}
```

Next, using got before category and currency get hotels list with `50` results:

📌Note: you can use both `name` or `value`.

```javascript
airbnb.getHotels("Design", "BRL", 50).then(console.log);
```

Output:

```json
[
   {
      "thumbnail":"https://a0.muscache.com/im/pictures/74102172/9815f41f_original.jpg?im_w=720",
      "title":"Bolzano, Italy",
      "subtitles":[
         "Designed by Peter Pichler",
         "Apr 15 – 20"
      ],
      "price":{
         "currency":"R$",
         "value":1417,
         "period":"night"
      },
      "rating":4.8,
      "link":"https://www.airbnb.com/rooms/4594196"
   },
   {
      "thumbnail":"https://a0.muscache.com/im/pictures/397ed026-16a9-4418-af19-1d2b31fe0aa8.jpg?im_w=720",
      "title":"Korčula, Croatia",
      "subtitles":[
         "Luxury Lifestyle Awards: Best Luxury Villa Croatia",
         "Apr 1 – 6"
      ],
      "price":{
         "currency":"R$",
         "value":11290,
         "period":"night"
      },
      "rating":"No rating",
      "link":"https://www.airbnb.com/luxury/listing/34594127"
   },
   ... and other hotels
]
```

And then using one of the hotel links get hotel info:

```javascript
airbnb.getHotelInfo("https://www.airbnb.com/rooms/4594196").then((data) => {
  console.dir(data, { depth: null });
});
```

Output:

```json

In addition to this, Sabine was probably the best host I've had while using AirBnb. She was very helpful in helping us get reservations to local restaurants and actually made us a cake (this was an engagement trip, so she offered to make us one instead of actually getting one at a bakery). Overall, we had an amazing vacation. Sabine and the Mirror House definitely made it very special for us!"

### Booking hotels result with selected filters, currency, location, dates, amount of guests, and set for business purposes.

First, we need to get all available categories and currencies:

📌Note: you need to use `console.dir` method to see the depth of inner keys of more than two in the result object.

```javascript
console.dir(booking.getFilters(), { depth: null });
```

Output:

```json
{
   "currencies":[
      {
         "name":"Property's Currency",
         "value":"hotel_currency"
      },
      {
         "name":"Argentine Peso",
         "value":"ARS"
      },
    ... and other currencies
   ],
   "filters":{
      "budget":[
         {
            "name":"US$0 – US$50",
            "value":"pri=1"
         },
         {
            "name":"US$50 – US$100",
            "value":"pri=2"
         },
        ... and other budget options
      ],
      "propertyRating":[
         {
            "name":"1 star",
            "value":"class=1"
         },
         {
            "name":"2 stars",
            "value":"class=2"
         },
         {
            "name":"3 stars",
            "value":"class=3"
         },
        ... and other rating options
      ],
      ... and other filters
   }
}
```

Next, using got before an array of filters (`["pri=2", "3 stars"]`), currency, set location, dates, amount of guests, and set for business purposes:

📌Note: you can use both `name` or `value` for filters and currencies.

```javascript
booking
  .getHotels(["pri=2", "3 stars"], "Argentine Peso", undefined, "Miami", "22/05/2023", "27/05/2023", 3, 1, undefined, "business")
  .then(console.log);
```

- `["pri=2", "3 stars"]` - we choose a budget filter with a price limit of "US$50 – US$100" and a property rating filter with a "3 stars" limit;
- `"Argentine Peso"` - selected currency;
- `undefined` - didn't set the `resultsLimit` argument. That means we leave the default results limit (35 for `booking`);
- `"Miami"` - selected location;
- `"22/05/2023"` - check in date;
- `"27/05/2023"` - check out date;
- `3` - adults amount;
- `1` - children amount;
- `undefined` - didn't set the `rooms` argument. That means we leave the default needed rooms amount (1 for `booking`);
- `"business"` - we choose "traveling for work" filter;

Output:

```json

```javascript
hotelsCom.getHotelInfo("https://www.hotels.com/ho282954/hotel-10-opera-paris-france/").then((result) => console.dir(result, { depth: null }));

Across the street from hotel is a popular restaurant with people on street. The restaurant closes at midnight so noise is not a problem if you are in the front.

### Find the cheapest hotels from all sites, get top 10 hotel info, and save the results.

Full code:

```javascript
import { airbnb, booking, hotelsCom, saveToJSON } from "./index.js";

const getHotels = async (location, checkIn, checkOut) => {
  const hotels = [
    ...(await airbnb.getHotels(undefined, "USD", 50, location, checkIn, checkOut)),
    ...(await booking.getHotels(undefined, "USD", 50, location, checkIn, checkOut)),
    ...(await hotelsCom.getHotels(undefined, undefined, undefined, "United States", undefined, 50, location, checkIn, checkOut)),
  ];

  return hotels
    .sort((a, b) => {
      let aValue = a.price?.value;
      let bValue = b.price?.value;
      if (a.price?.taxesAndCharges || (a.price?.period && a.price?.period !== "night")) {
        aValue = a.price?.value / 10;
      }
      if (b.price?.taxesAndCharges || (b.price?.period && b.price?.period !== "night")) {
        bValue = b.price?.value / 10;
      }
      return aValue - bValue;
    })
    .slice(0, 10);
};

const getInfo = async (hotels) => {
  const results = [];
  for (const hotel of hotels) {
    const { link, price } = hotel;
    if (link.includes("airbnb.com")) {
      results.push({ ...(await airbnb.getHotelInfo(link)), price });
    } else if (link.includes("booking.com")) {
      results.push({ ...(await booking.getHotelInfo(link)), price });
    } else results.push({ ...(await hotelsCom.getHotelInfo(link)), price });
  }
  return results;
};

getHotels("Miami", "07/18/2023", "07/28/2023").then(getInfo).then(saveToJSON);
```

Explanation:

First, we get hotels from each website located in "Miami" and free from `07/18/2023` to `07/28/2023`:

```javascript
getHotels("Miami", "07/18/2023", "07/28/2023");
```

In `getHotels` function we get 50 hotels from each website, then sort them by price ascendent, and leave the 10 most cheap:

```javascript
const getHotels = async (location, checkIn, checkOut) => {
  const hotels = [
    ...(await airbnb.getHotels(undefined, "USD", 50, location, checkIn, checkOut)),
    ...(await booking.getHotels(undefined, "USD", 50, location, checkIn, checkOut)),
    ...(await hotelsCom.getHotels(undefined, undefined, undefined, "United States", undefined, 50, location, checkIn, checkOut)),
  ];

  return hotels
    .sort((a, b) => {
      let aValue = a.price?.value;
      let bValue = b.price?.value;
      if (a.price?.taxesAndCharges || (a.price?.period && a.price?.period !== "night")) {
        aValue = a.price?.value / 10;
      }
      if (b.price?.taxesAndCharges || (b.price?.period && b.price?.period !== "night")) {
        bValue = b.price?.value / 10;
      }
      return aValue - bValue;
    })
    .filter((el, i) => i < 10);
};
```

After hotels are received and filtered, we call `then` function and give received hotels into `getInfo` function:

```javascript
.then(getInfo)
```

In `getInfo` we iterate over all hotels, receive each hotel info, push them in `results` array and return it:

```javascript
const getInfo = async (hotels) => {
  const results = [];
  for (const hotel of hotels) {
    const { link, price } = hotel;
    if (link.includes("airbnb.com")) {
      results.push({ ...(await airbnb.getHotelInfo(link)), price });
    } else if (link.includes("booking.com")) {
      results.push({ ...(await booking.getHotelInfo(link)), price });
    } else results.push({ ...(await hotelsCom.getHotelInfo(link)), price });
  }
  return results;
};
```

And the last one, we call `then` function and give received hotels into `saveToJSON` function:

```javascript
.then(saveToJSON)
```

The result is the saved `parsed_results.json` file in your app directory with top-10 cheapest hotels with full description.
