Your mission, if you choose to accept it is to implement a scraper for MEPs (Members of the European Parliament).
You need Node installed locally, version 10.16.3 or later is recommended. We suggest using nvm to manage your node versions.
Please refer to the .eslintrc.json for the ESLint configuration. General rules:
- ES6 (babel)
- Indentation using two spaces
- Single quotes for strings
- Max line length is 150 characters
The tools available at your disposal are built in Node.js libraries (like http) and the third party library cheerio (DOM parsing). The list of MEPs can be found here: europarl.europa.eu/meps/en/full-list.html
The asynchronous function you're implementing is called scrapeEULegislators and it's in the file scraper.js. In the directory test we have predefined tests defined that verify the output of your implementation, you can run the tests using the command npm test to verify.
The structure expected by the tests is an array with each MEP, in the same order as they appear on the website with the following object structure:
{
name: "Name of the MEP",
lastName: "Last name of the MEP",
partyGroup: "Name of the party group",
country: "Name of the country they're from",
url: "The URL to the MEP biography page",
image: "The URL to the image of the MEP",
}
Feel free to separate concerns (e.g. http requests, DOM parsing) and structure it in a way that's readable and makes sense to you.
- Traversing the DOM with Cheerio is like using jQuery, when
maping a set of elements you must however always use.get()after the.map()to get the results in an array. - As the scraper will be performing a lot of HTTP requests and you'll most likely end up with a loop awaiting the response from each individual page, you may want to break the loop after the first iteration. The test will still pass.
- Last name isn't as obvious as it seems with special characters, don't get too hung up on it.
Good luck!
