Macil / fetchRecursively.js
Created Jul 4, 2018
An example of using Kefir streams with a recursive function.
View fetchRecursively.js
'use strict';
const Kefir = require('kefir');
// fetch takes a url string, pretends to fetch it over the network, and returns
// a Kefir stream that emits a Page object when it's done, and then the stream
// ends.
function fetch(url) {
let links;
switch (url) {
case '': links = ['', '']; break;
Macil / loadInContentScript.js
Created Mar 7, 2018
This function allows you to load javascript from a remote url with an extension content script, and have the loaded javascript execute within the content script's isolated world.
View loadInContentScript.js
async function loadInContentScript(url) {
// Note that this extension must either have permission to the domain of this
// URL, or the URL must be served with the correct CORS HTTP headers to allow
// this script to fetch it (ie. "Access-Control-Allow-Origin: *").
const response = await fetch(url);
const scriptText = await response.text();
// Let Chrome devtools know where this code came from.
const codeToRun = scriptText + "\n//# sourceURL=" + url + "\n";
View content.js
// This code is assumed to be part of one of the extension's content scripts
function addIframe() {
const iframe = document.createElement('iframe');
iframe.addEventListener('load', () => {
eventName: 'init',
iframeSrc: '' // whatever url you want. Probably will be a URL to your own domain in practice
}, '*');
}, false);

// jshint evil:true
// Q: Why put the code into a function before executing it instead of
// evaling it immediately?
// A: Chrome would execute it before applying any remembered
// breakpoints.
// Q: Why not just use `... = new Function(...)`?
// A: The sourcemaps would be off by one line in Chrome because of
