Usage

Scrape

constructor(hostname: string, path: string, scrapingFunction: Function)

• hostname - The hostname of the domain you want to request. Ex. 'github.com'
• path - The endpoint you want to request at the given hostname. Use '/' for the root.
• scrapingFunction(response) - The function you define that will process the response you got from your request, where your scraped data is created.

async scrape()

• Sends an https request to the given address (hostname + path) and calls the scrapingFunction using the https response as the input.
• Returns the result of the scrapingFunction

Scraper

queuedScrapes: Scrape[]

• An Array of Scrapes that will be scraped in order when scrapeAll() is called.

completedScrapes: any[]

• An array of the results returned by Scrape.scrape() when scrapeAll() is called.

intervalTime: number

• Value representing milliseconds between requests when scrapeAll() is called. Used to prevent overwhelming clients with requests and using up resources. Default value = 1000ms or 1 second/request.

addScrape(scrape: Scrape)

• Add a Scrape Object to the queuedScrapes. You can also add an array of Scrapes using addScrapes(scrapes: Scrape[])

scrapeAll()

• Goes through the queuedScrapes and calls Scrape.scrape() based on the set intervalTime. Returned results are pushed into completedScrapes.
