A simple app that scrapes rightmove for flats and sends them to a Telegram chat.
#!/usr/bin/env node
const cheerio = require('cheerio')
const fetch = require('node-fetch')
const loki = require('lokijs')
const telegram = require('telegram-bot-api')
const api = new telegram({ token: process.env.TELEGRAM_API });
const db = new loki('rightmoveFile', {
autoload: true,
autoloadCallback : databaseInitialize,
autosave: true,
autosaveInterval: 4000
})
// implement the autoloadback referenced in loki constructor
function databaseInitialize() {
let propertiesDB = db.getCollection('properties')
if (propertiesDB === null) {
propertiesDB = db.addCollection('properties', { indices: 'id' })
}
}
// TODO: Build up URL.
const url = 'PASTE THE RIGHTMOVE RESULTS PAGE URL HERE'
fetch(url).then(response => response.text()).then(async html => {
const $ = cheerio.load(html)
const script = $('script').eq(2)
const json = script.html().replace('window.jsonModel =', '')
const data = JSON.parse(json)
const propertiesDB = db.getCollection('properties')

propertiesDB.insert(property)
return property
})
for (const property of properties.reverse()) {
