JSON Endpoint Example 2

node v4.9.1

version: 1.0.0

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.

Doesn't seem to work for any available version of NodeJS above v6.17.1 ...
