How to Use the JavaScript Fetch API to Get Data We all remember the dreaded XMLHttpRequest we used back in the day to make requests, it involved some really messy code, it didn't give us promises and let's just be honest, it wasn't pretty JavaScript, right? Maybe if you were using jQuery, you used the cleaner syntax with jQuery.ajax(). Well JavaScript has it's own built-in clean way now. Along comes the Fetch API a new standard to make server request jam-packed with promises and all those things we learned to love over the years. npm Documentation One of the key steps in becoming immersed in an ecosystem is learning its vocabulary. Node.js and npm have very specific definitions of packages and modules, which are easy to mix up. We'll discuss those definitions here, make them distinct, and explain why certain default files are named the way they are. A package is a file or directory that is described by a package.json. This can happen in a bunch of different ways! For more info, see "What is a package?

Node.js real time logging with Winston, Redis and, p2 Following up on my last blog post Node.js real time logging with Winston, Redis and, p1 I want to get into the integration of winston with to stream logs real time to a browser. So just a quick recap, the idea here is to have a mechanism that logs messages categorized by different levels in the server and displays them at the same time in the browser, keeping the user informed at all times of the action in the back end, or helping a developer spot some bugs without the need to keep an eye on the terminal console or searching for log files buried in the server.

Twitter Steps Down From the Free Speech Party In 2012, when Twitter announced in a blog post that it was launching a system that would allow the company to take down content on a country-by-country basis—as opposed to taking it down across the entire Twitter network—EFF defended that decision as the least terrible option. After all, when a company refuses to comply with an official government request, the government's response is often to block an entire platform. We pointed out that companies cannot be compelled to follow court orders from countries where they do not have significant assets or employees. As a result, we could expect that Twitter would comply only with court orders from the United Kingdom, Ireland, Japan, and Germany.

Building a JavaScript Development Environment Hi everyone, my name is John Smith , welcome to my course, PHP: Getting Started. I am a PHP programmer at The Mill.

The previous article I wrote on this used a strategy where you would lock up all your components, but have a dependency to the state tree of the application in each component that needed it. The individual components could point cursors into the state tree, allowing the component to extract state from the state tree and render itself whenever the cursor notified about a change.

Internet of Things - Privacy and Security in a Connected World The Federal Trade Commission held a public workshop to explore consumer privacy and security issues posed by the growing connectivity of devices. The ability of everyday devices to communicate with each other and with people is becoming more prevalent and often is referred to as “The Internet of Things.” Connected devices can communicate with consumers, transmit data back to companies, and compile data for third parties such as researchers, health care providers, or even other consumers, who can measure how their product usage compares with that of their neighbors.

The Danger Crew RPG: Lessons Learned by Drew Conley on CodePen The day is finally here. The Danger Crew, an RPG game built with React and Redux, is ready to play! I made a Celebration Pen for it: #Intro and Background History of Node.js on a Timeline We’ve been publishing articles on Node.js for over a year now, and since 2015 was quite a year for Node.js, we thought it’d be interesting to look back at what exactly happened to Node.js so far, from the point where it was born. This is the history of Node.js on a timeline, from 2009 until now (December 2015): Ghost: Blogging with Node.jsGhost is an open source publishing platform which is beautifully designed, easy to use, and free for everyone.

Backend Apps with Webpack (Part I) Webpack is an amazing tool. It calls itself a "module bundler" but it is much more than that: it provides an infrastructure for building, transforming, and live updating modules. While its wall of configuration options may not be your style, this approach works really well for the problem it's solving. In fact, the style of its documentation and APIs are not my favorite, but it all comes together as a really powerful (and sorely needed) tool. Holographic principle In a larger sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure "painted" on the cosmological horizon[clarification needed], such that the three dimensions we observe are an effective description only at macroscopic scales and at low energies. Cosmological holography has not been made mathematically precise, partly because the particle horizon has a finite area and grows with time.[4][5] The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon.
