API to scrape dynamically generated contents in a webapge.

This API takes in the url of a webpage and css selector id of the content to be scrapped and returns the outer html text of the scrapped content. It is hosted in heroku and works using Puppeteer (to enable headless scraping) and ExpressJS (to serve the app).

Reference Detail
API Format https://acciotables.herokuapp.com/?page_url=some_content&content_selector_id=some_content
Attributes page_url : The URL of the webpage on which the content to be scrapped is available (in html encoded format)
content_selector_id : CSS Selector ID of a particular table or any html element (in html encoded format)
Request Method GET : GET methods means the API returns you something you ask
Response Type text/html : Outer HTML content of the scrapped table (or any html element)

Sample usage:

Note: Since the API is deployed on Heroku, it might take a while to wake the web process if the webapp had been idle for last few minutes and needs to be moved from idle to running. Once it's up and running it will take a maximum of 4 seconds to produce the result.

  • From the above image we get to know that the css selector id for the "Squads Goalkeeping" table is #stats_keeper_squads.
  • In order to scrap the table, all we need to do is call the API as http://acciotables.herokuapp.com/?page_url=https://fbref.com/en/comps/22/Major-League-Soccer-Stats&content_selector_id=%23stats_keeper_squads. Note that # is replaced with its ASCII value %23 as URL's don't accept some symbols. Remember to swap # with %23 or refer to this page for more details for encoding other symbols.
  • The result is as follows: (we get the table in html format)

Calling the API in R:

require(rvest)
require(dplyr)
page <- read_html("http://acciotables.herokuapp.com/?page_url=https://fbref.com/en/comps/22/Major-League-Soccer-Stats&content_selector_id=%23stats_keeper_squads")
table <- page %>% html_table()
table <- table[[1]] 
print(table)

Using the API in Python:

import pandas as pd
url = "http://acciotables.herokuapp.com/?page_url=https://fbref.com/en/comps/22/Major-League-Soccer-Stats&content_selector_id=%23stats_keeper_squads"

df = pd.read_html(url,header=0)
print(df)
