Would you like to clone this notebook?
When you clone a notebook you are able to make changes without affecting the original notebook.
Send a request like ?url=http://google.com, get back the title of the page.
var endpoint = require("@runkit/runkit/json-endpoint/1.0.0")
var request = require("request")
var cheerio = require("cheerio")
endpoint(module.exports, function(req, done)
{
request(req.query.url, function(error, response, body)
{
if (error) return done({error: "could not retrieve page"})
var page = cheerio.load(body)
done({
title: page("title").text() || "no title"
})
})
})
Instead of promises, we're using callbacks, and explicitly calling "done" with whatever value we want to return to the caller.
