Introduction is an open source JavaScript runtime environment for easily building server-side applications. It's also the runtime that powers many client-side development tools for modern JavaScript frameworks. In this tutorial, you'll set up a Node.js programming environment on your local macOS machine using, and you'll test your environment out by writing a simple Node.js program. Prerequisites You will need a macOS computer running High Sierra or higher with administrative access and an internet connection. Step 1 — Using the macOS Terminal You'll use the command line to install Node.js and run various commands related to developing Node.js applications. The command line is a non-graphical way to interact with your computer. Instead of clicking buttons with your mouse, you'll type commands as text and receive text-based feedback. The command line, also known as a shell, lets you automate many tasks you do on your computer daily, and is an essential tool for software developers. To access the command line interface, you'll use the Terminal application provided by macOS. Like any other application, you can find it by going into Finder, navigating to the Applications folder, and then into the Utilities folder. From here, double-click the Terminal application to open it up. Alternatively, you can use Spotlight by holding down the COMMAND key and pressing SPACE to find Terminal by typing it out in the box that appears. ![]() 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. If you'd like to get comfortable using the command line, take a look at. The command line interface on macOS is very similar, and the concepts in that tutorial are directly applicable. Now that you have the Terminal running, let's install some prerequisites we'll need for Node.js. Step 2 — Installing Xcode's Command Line Tools Xcode is an integrated development environment (IDE) that is comprised of software development tools for macOS. You won't need Xcode to write Node.js programs, but Node.js and some of its components will rely on Xcode's Command Line Tools package. Execute this command in the Terminal to download and install these components: • xcode-select --install You'll be prompted to start the installation, and then prompted again to accept a software license. Then the tools will download and install automatically. We're now ready to install the package manager Homebrew, which will let us install the latest version of Node.js. Step 3 — Installing and Setting Up Homebrew While the command line interface on macOS has a lot of the functionality you'd find in Linux and other Unix systems, it does not ship with a good package manager. A package manager is a collection of software tools that work to automate software installations, configurations, and upgrades. They keep the software they install in a central location and can maintain all software packages on the system in formats that are commonly used. Is a free and open-source software package managing system that simplifies the installation of software on macOS. MacOS with earlier versions of Docker. Docker for Mac v 17.12 to v 18.02. Same as above but use docker.for.mac.host.internal instead. Docker for Mac v 17.06 to v 17.11. Same as above but use docker.for.mac.localhost instead. Docker for Mac 17.05 and below. To access host machine from the docker container you must attach an IP alias to your network interface. We'll use Homebrew to install the most recent version of Node.js. To install Homebrew, type this command into your Terminal window: • /usr/bin/ruby -e '$(curl -fsSL The command uses curl to download the Homebrew installation script from Homebrew's Git repository on GitHub. Let’s walk through the flags that are associated with the curl command: • The - f or --fail flag tells the Terminal window to give no HTML document output on server errors. • The -s or --silent flag mutes curl so that it does not show the progress meter, and combined with the -S or --show-error flag it will ensure that curl shows an error message if it fails. • The -L or --location flag will tell curl to handle redirects. If the server reports that the requested page has moved to a different location, it'll automatically execute the request again using the new location. Once curl downloads the script, it's then executed by the Ruby interpreter that ships with macOS, starting the Homebrew installation process. The installation script will explain what it will do and will prompt you to confirm that you want to do it. This lets you know exactly what Homebrew is going to do to your system before you let it proceed. It also ensures you have the prerequisites in place before it continues. You'll be prompted to enter your password during the process. However, when you type your password, your keystrokes will not display in the Terminal window. This is a security measure and is something you'll see often when prompted for passwords on the command line. Adobe photoshop elements 12 for mac free download 2017.
