Node.js V0.8.18 (for Mac)

JavaScript is one of the most popular programming languages in the world. Because it’s built into most web browsers, programmers and web designers can use JavaScript to add interactive features to websites that reach billions of people. But in the past couple of years, JavaScript has started to play a larger role outside of the browser, due in large part to Node.js. Node.js is a tool for building fast network applications. It’s known as a “JavaScript runtime environment” which simply means it lets you write JavaScript code that can run on your computer free of any web browser. Node.js is used to create fast web servers by companies like Walmart, eBay and Netflix.

But because Node.js can be used on your desktop computer, programmers have created useful Node-based tools that help with the process of building web sites. For example, is a popular tool used to automate common tasks like compiling files to CSS, making JavaScript files smaller so they load in less time, and compressing images to smaller file size. While these tools run through the Node.js environment, you’ll use another tool, NPM, to install them. NPM is what’s called a “package manager.” NPM makes installing a tool like Grunt as easy as npm install -g grunt-cli. But before you can use Node.js or NPM you need to install them — while the NodeJS website includes an installer, there’s a better way to install them on a Mac.

In this article, I’ll take you through the process of installing Node.js and NPM on a Mac using Homebrew., I’ll show you Windows users how to install them on the Windows operating system. Prerequisites Before you install Node.js and NPM you’ll first need to have some familiarity with the Mac Terminal application. Terminal lets you dig into the underbelly of the operating system and issue text commands to your computer. You’ll need to use Terminal (or a similar application like ) to not only install Node.js but also to use it and NPM. Before you can install Node, you’ll need to install two other applications. Fortunately, once you’ve got these on your machine, installing Node takes just a few minutes.

Apple’s XCode development software is used to build Mac and iOS apps, but it also includes the tools you need to compile software for use on your Mac. XCode is free and you can find it in the.

Best video editor software for mac. Homebrew. Homebrew is a package manager for the Mac — it makes installing most open source sofware (like Node) as simple as writing brew install node. You can learn more about Homebrew at the. To install Homebrew just open Terminal and type ruby -e '$(curl -fsSL You’ll see messages in the Terminal explaining what you need to do to complete the installation process. Why Homebrew?

Observant readers will notice in the screenshot above that there’s an installer for NodeJS. You can download it directly from. I recommend Homebrew over that installer for a few reasons:. When installing Node via the installer, you have to use the sudo command to make sure it installs properly (there is a workaround for this, but it’s complicated). Sudo lets the installer place files in areas of your file system that are only accessible to administrators. One nice thing about Homebrew is that it doesn’t require access to administrator-only areas of your computer in order to install NodeJS (or any other package). This is a safer approach as it makes sure that any package you install with Homebrew can’t wreak havoc on your computer.

After installing Node via the installer you have to add the path to the node executable to your system $PATH. This involves mucking around with your shell login file. For experienced Terminal users or Unix-people this isn’t a big deal, but for those new to the command line that step can be daunting.

Although the Homebrew method involves installing several different pieces of software, it’s generally just a simple process of point-click-and-wait. It takes a bit longer this way but there’s less room for error.

Homebrew is a great tool for web developers. First, it makes removing Node very easy (otherwise you have to crawl through your file system and delete a bunch of files manually). Second, it greatly simplfies the installation of other useful packages like Git, Ruby, or the very useful utility. Installation Installing Node.js and NPM is pretty straightforward using Homebrew. Homebrew handles downloading, unpacking and installing Node and NPM on your system. The whole process (after you have XCode and Homebrew installed) should only take you a few minutes.

Open the Terminal app and type brew install node. Sit back and wait.

Homebrew downloads some files and installs them. And that’s it. To make sure you have Node and NPM installed, run two simple commands to see what version of each is installed:. To see if Node is installed, type node -v in Terminal. This should print the version number so you’ll see something like this v0.10.31. To see if NPM is installed, type npm -v in Terminal.

This should print the version number so you’ll see something like this 1.4.27 How to Update Node and NPM New versions of Node and NPM come out frequently. You can use Homebrew to update the software it installs. Make sure Homebrew has the latest version of the Node package. In Terminal type brew update. Upgrade Node: brew upgrade node How to Uninstall Node and NPM You can use Homebrew to uninstall packages that it installed: brew uninstall node With Node.js and NPM installed you’ll soon be able to take advantage of the huge world of NPM modules that can help with a wide variety of tasks both on the web server and on your desktop (or laptop) machine. Lists all of the official Node packages making it easy to make the choice.

I think this tutorial is very informative, but I can’t understand why so many writers ignore the basics of good online communication. Your gray text on a gray background “is” readable, but not without effort. Is this a design decision? Why not make the text black to increase contrast and readability?

And, your links, in light blue, are even worse—I cannot read them on my high-resolution 30″ monitor. I am amazed that you ignore these communications basics, when you purport to be a communications company. I must disagree on what you say, because I think that the contrast from background to the typo is just fine. The problem is, if you choose a too strong contrast it will be very difficult for the eyes to read a lot of text.

To better understand what I am meaning I advice you to take a piece of paper which is intended for laserprinting/xeroxing. But don’t take the environmental greyish paper but the one that is super white.

Now print in the size of 9 to 11 pt some text in a robust font like times, garamond or helvetica. You will see that the words start to flicker in your eyes. Now print the same text on a greyish environmental piece of paper and you will notice that the text will be much more readable and your eyes will not start getting tired that fast. This is due to reduced contrast between text and background.

The problem is that in our eyes there is a contrast enriching mechanism working if two adjacted photoreceptor cells are receiving very contrasting amounts of light. The one that receives a lot of light uses up the visual purpur (which is needed for the cells to create the light perceprion) of it’s neighboring photoreceptors thus making the perception of those receptors that receive very little light even darker. And if this contrast just gets to strong our eye is just not capable to handle this contrast any more and the vision gets blurry/flickering.

If you look at high quality thread bound reading books without pictures (a novel for example) you will notice that it mostly is printed on natural colored paper and that is not because the printer wanted to save money, in fact this naturally colored paper is way more expensive as the highly bleached super white xerox paper you get at the supermarket. Now look at the contrast between black and white on an average computer screen and you will notice that the contrast is even stronger than on super white copying paper. Therefore it is strongly recommended to either brighten up the typo or dimming down the white of the background (or do both). You can even colour it a bit as long as it does not get too saturated. Outstanding tutorial on node.js et al. I wish I had stumbled upon your site a few weeks ago when I ‘tried’ installing the ‘other’ way. I ended up following your instructions to a “T” after I removed node.jsit worked like a charm.

I especially like the fact that I now have Homebrew which I knew existed, just didn’t know the reason why. I’m going to hunt around your site to see what else I can learn. Possibly find a course that i can take as well. Thanks again for the tutorialI’m off to play in node.js and the like! To support and at the same time, challenge the idea of installing node via homebrew. I initially did the install via the installer pkg.

But I am using a non-admin user to do all my stuffs, developments and so. So I got stuck into even more challenging issues with the permissions. So I decided to remove the packaged install and re-install via homebrew. It went like a charm. Now, a month later, I want to install ghost and kickstart a project.

However, ghost supports Node only up to v. 4.2 and the current node version is 5.1 I’ve been using npm and node for many things in the last month and installed a bunch of things using npm. Because I used homebrew in the first (well, second actually) place, I can easily uninstall node via homebrew, install nvm via homebrew and install the node versions I need via nvm. Makes sense, no? Actually, with node, nvm is the the way to go.

Thanks for the instructions. I’m new to this, so I don’t know what is wrong. I got this warning from the Homebrew installation Warning: /usr/local/bin is not in your PATH.

Here is my path as displayed from ‘echo $PATH’ (where ‘me’ is my user name). “/Users/me/:/Users/me/bin:/usr/bin:/bin/:/usr/sbin:/sbin:/usr/local/bin” Notice at the end, it shows /usr/local/bin like the warning mentioned. Should there be a colon for slash after that (should there be a slash after every ending folder name)? If this path looks funky, it may be because I was trying to fix a goof from a node-v4.2.1.pkg installation. If there is anything that I should now remove since I am going through the Homebrew installation of Node, please let me know. Hi Paolo, Good question.

Yes, there is an installer package for Node. There are a couple of reasons why I recommend Homebrew instead: 1.

Second, it makes installing other useful packages easy like Git, Ruby, or the very useful wget utility. I’ve updated the article to include these ideas. Thanks for the feedback! Just want to second (or third?) that installing Node, NPM, Mongo, and so on, from Homebrew is preferred for most developer installations.

Makes managing versions easier, updating, removing, and so on. Also, the biggest benefit for me is that you don’t need to muck with permissions when running applications, installing packages with NPM, and sometimes even building Which can require sudo to work properly, something that can get annoying when you’re managing your application’s dependencies. I followed these instructions to completely remove Node and NPM, and then re-installed via homebrew.

The SEMVER-MINOR changes include:. build: export openssl symbols on Windows making it possible to build addons linking against the bundled version of openssl (Alex Hultman). debugger: make listen address configurable in the debugger server (Ben Noordhuis). dgram: generalized send queue to handle close fixing a potential throw when dgram socket is closed in the listening event handler.
