### Start Live Database Replication (JavaScript)

Source: https://themeparks.github.io/parksapi/parks_wdw_wdwdb.js

Starts a live replication process between a remote database and the local instance. It includes logic to automatically restart replication on errors or timeouts. The replication is configured to be live and to retry on connection failures. Dependencies include PouchDB and timers for managing timeouts.

```javascript
_replicate() {
  if (this.replicating) return;
  this.replicating = true;

  let noChangeTimeout = null;
  let replicationHandle = null;
  const noChangeTimer = Number(this.config.restartTimeout) || 5;

  const rebootReplicator = (err) => {
    if (noChangeTimeout) {
      clearTimeout(noChangeTimeout);
    }
    if (replicationHandle) {
      replicationHandle.cancel();
      replicationHandle = null;
    }

    if (err) {
      console.error('Replication Error!', new Date(), err);
    }

    this.replicating = false;
    setTimeout(this._replicate.bind(this), 1000);
  };

  const resetTimeoutTimer = () => {
    if (noChangeTimeout) {
      clearTimeout(noChangeTimeout);
    }
    noChangeTimeout = setTimeout(() => {
      rebootReplicator();
    }, 1000 * 60 * noChangeTimer);
  };

  try {
    replicationHandle = PouchDB.replicate(this.remoteDB, this, {
      live: true,
      retry: true,
    }).on('change', () => {
      resetTimeoutTimer();
    }).on('error', (e) => {
      rebootReplicator(e);
    });

    resetTimeoutTimer();
  } catch (e) {
    rebootReplicator(e);
  }
}
```

### Initialize Park and Start Update Loop (JavaScript)

Source: https://themeparks.github.io/parksapi/parks_park.js

Initializes the park object and, if not disabled and online, starts a recurring update loop. The loop schedules updates at a defined interval, ensuring data is kept current. It handles potential errors during initialization and update processes.

```javascript
async _runInit() {
    try {
      await this._init();
      this.initialised = true;

      if (!this.config.disableParkUpdate && !this.offline) {
        // start an update loop
        // use a separate function so we can quickly loop back around
        const scheduleUpdate = async () => {
          // pause for our updateInterval time
          await delay(this.config.updateInterval);

          // if our udpates get disabled during our timer, then skip and exit our
          if (this.config.disableParkUpdate) return;

          // wait for Promise to resolve, grab any catches, then continue anyway
          this.update().then().catch().then(() => {
            if (this.config.disableParkUpdate) return;

            // schedule another update
            setImmediate(scheduleUpdate.bind(this));
          });
        };

        // start the first loop timer
        scheduleUpdate();
      }
    } catch (e) {
      console.error('Error initialising park', e);
    }
  }
```

### Abstract Post-Initialization Method (_postInit) in JavaScript

Source: https://themeparks.github.io/parksapi/parks_park.js

This abstract JavaScript method `_postInit` is designed for child classes to override. It is called after the main initialization process, likely for additional setup tasks. It currently has no implementation and is intended for extension.

```javascript
async _postInit() {
    // implementation should be setup in child classes
  }
```

--------------------------------

### Get Entity Live Data - JavaScript

Source: https://themeparks.github.io/parksapi/parks_destination.js

Retrieves and processes all live data for entities. It first initializes the system, then calls `buildEntityLiveData` to get the data. It iterates through the generated live data, updating each entity's live data and handling potential errors during the update process.

```javascript
async getEntityLiveData() {
    await this.init();
    const liveData = (await this.buildEntityLiveData()) || [];

    // process all live data we generated
    for (let liveDataIdx = 0; liveDataIdx < liveData.length; liveDataIdx++) {
      const data = liveData[liveDataIdx];
      try {
        await this.updateEntityLiveData(data._id, data);
      } catch (e) {
        // if (!e instanceof EntityNotFound) {
        console.error(`Failed to apply live data to ${data._id}`);
        console.error(e);
        // }
        // 19411262;entityType=Attraction = Pop/Art Skyliner Line
        // 19404062;entityType=Attraction = Hollywood Studios Skyliner Line
        // 19404065;entityType=Attraction = Epcot Skyliner Line
      }
    }

    return liveData;
  }
```

--------------------------------

### Helper Function for GET Requests (JavaScript)

Source: https://themeparks.github.io/parksapi/parks_http.js

A convenience function to simplify making HTTP GET requests. It takes a URL, optional data payload, and optional request options, then calls the main HTTP function.

```javascript
/**
 * Helper function to make a GET request
 * @param {string} url URL to request
 * @param {object} [data] data to send. Will become querystring for GET, body for POST
 * @param {object} [options = {}] Object containing needle-compatible HTTP options
 * @return {Promise<*>} 
 */
mainFunction.get = (url, data, options) => {
  return mainFunction('GET', url, data, options);
};
```

The function also starts live replication if configured and a remote database is available. Dependencies include PouchDB for replication and console for logging.

```javascript
async init() {
  if (this.synced) {
    return;
  }

  if (this.initPromiseSync) return this.initPromiseSync;

  this.initPromiseSync = this._loadAndInit();
  await this.initPromiseSync;

### Initialize and Create Indexes (JavaScript)

Source: https://themeparks.github.io/parksapi/parks_wdw_wdwdb.js

Manages the initialization of database indexes. The `_initIndexes` function ensures that indexes are created only once by checking internal flags and promises. The `_createIndexes` function calls individual index creation methods for various index types like entities, channels, and facility status.

```javascript
async _initIndexes() {
    if (this._indexSetup) {
      return;
    }

    if (this._setupPromise) {
      return this._setupPromise;
    }

    this._setupPromise = this._createIndexes();
    await this._setupPromise;
    this._indexSetup = true;
    return;
  }
```

```javascript
async _createIndexes() {
    await this._createIndex(constants.INDEX_ENTITIES);
    await this._createIndex(constants.INDEX_CHANNELS);
    await this._createIndex(constants.INDEX_FACILITYSTATUS, []);
    await this._createIndex(constants.INDEX_CHILDREN);
    await this._createIndex(constants.INDEX_NAMES);
    await this._createIndex(constants.INDEX_IDS, []);
  }
```

### JavaScript: Initialize AttractionsIO with Configuration and API Hooks

Source: https://themeparks.github.io/parksapi/parks_attractionsio_attractionsio.js

Initializes the AttractionsIO class with essential configuration parameters like destination ID, park ID, base URL, API key, and app details. It sets up API request hooks to automatically include authentication headers and the current date for every request made to the Attractions.io API.

### Europa Park Database Class Initialization and HTTP Interceptors (JavaScript)

Source: https://themeparks.github.io/parksapi/parks_europa_europaparkdb.js

Initializes the Europa Park database connection, setting up required API credentials, encryption keys, and configuring HTTP interceptors. These interceptors automatically inject the correct user agent and JWT authorization headers for API requests and handle token refresh on unauthorized responses.

```javascript

### Get Facility Status by ID - JavaScript

Source: https://themeparks.github.io/parksapi/parks_wdw_wdwdb.js

Retrieves the status document for a specific facility ID. It first initializes the database, finds the facility status index, and then looks up the entity by its ID. If the entity is not found, it returns undefined. Dependencies include 'constants' and the internal 'init', 'getIndex', and 'get' methods.

```javascript
async getFacilityStatus(id) {
    await this.init();

    const statusIndex = this.getIndex(constants.INDEX_FACILITYSTATUS);

    // look up entity ID in our facility status index
    const indexEntity = statusIndex.find((x) => {
      return x.id === id;
    });
    if (!indexEntity) return undefined;

    return await this.get(indexEntity._id);
  }
```

### Process and Format Park Schedules with Moment.js

Source: https://themeparks.github.io/parksapi/parks_attractionsio_attractionsio.js

Processes a list of day ranges to create a formatted schedule of opening and closing times for a park. It uses Moment.js with timezone information to handle date and time calculations accurately. The output is an array of schedule entries, sorted by date and opening time.

```javascript
      if (scheduleDescription) {
        scheduleEntry.description = scheduleDescription;
      }

      // Process each day range
      days.ranges.forEach(dayIndex => {
        // The dayIndex appears to be calculated as: monthIndex * 31 + dayOfMonth - 1
        // where monthIndex is 0-based (0=Jan, 1=Feb, etc.)
        const month = Math.floor(dayIndex / 31);
        const day = (dayIndex % 31) + 1;

        // Create date object
        const date = moment.tz([currentYear, month, day], this.config.timezone);

        // Skip invalid dates
        if (!date.isValid() || date.date() !== day) return;

        // Create opening and closing times
        const openingTime = date.clone().hour(openHour).minute(openMinute).second(0).millisecond(0);
        const closingTime = date.clone().hour(closeHour).minute(closeMinute).second(0).millisecond(0);

        schedule.push({
          date: date.format('YYYY-MM-DD'),
          openingTime: openingTime.format(),
          closingTime: closingTime.format(),
          ...scheduleEntry,
        });
      });
    });

    // Sort schedule by date and opening time (to handle multiple venues per date)
    const finalSchedule = schedule.sort((a, b) => {
      const dateCompare = a.date.localeCompare(b.date);
      if (dateCompare !== 0) return dateCompare;
      // If dates are the same, sort by opening time
      return a.openingTime.localeCompare(b.openingTime);
    });

    return [
      {
        _id: this.config.parkId,
        schedule: finalSchedule,
      }
    ];
  }
}

### Initialize LMDB Cache and Directory - JavaScript

Source: https://themeparks.github.io/parksapi/cache_cacheLmdb.js

This constructor initializes the LMDB cache. It ensures the cache directory exists, creating it if necessary, and then opens the LMDB database file. It relies on the 'path', 'fs', and 'lmdb' modules. The database is configured with compression enabled.

```javascript
import CacheBase from './cacheBase.js';
import path from 'path';
import fs from 'fs';
import {open} from 'lmdb';

export default class CacheLmdb extends CacheBase {
  constructor(options = {}) {
    super(options);
    
    const cacheDirPath = path.join(process.cwd(), 'datacache');
    if (!fs.existsSync(cacheDirPath)) {
      fs.mkdirSync(cacheDirPath);
    }
    
    const cacheDbpath = path.join(cacheDirPath, 'cache.lmdb');
    
    this.db = open({
      path: cacheDbpath,
      compression: true,
    });
  }
  
  async _get(key) {
    return this.db.get(key);
  }
  
  async _set(key, object) {
    await this.db.put(key, object);
  }
  
  async _del(key) {
    await this.db.remove(key);
  }
  
  async _getKeys(prefix) {
    const keys = [];
    for (const key of this.db.getKeys()) {
      if (!prefix || key.startsWith(prefix)) {
        keys.push(key);
      }
    }
    return keys;
  }
}
```
