node.js allows you to run javascript in the Terminal as appose to a regular browser which makes for a modern workflow in web development, with both node.js installed and a package manager called npm (Node Package Manager) also installed, which can manage other packages that work with node.js, one of the main ones being gulp.jsfor a web development workflow.
To install node.js on macOS Mojave, Sierra (and earner OSX versions) you can download a pre-compiled binary package which makes a nice and easy installation. Head over to http://nodejs.org/ and click the install button to download the latest package. Either version is Ok, if you are new to it best to use the recommended version.
The easiest approach is to download the package for your platform directly from the Nodejs.org website’s Downloads page and run the installation program. This is definitely the way to go if you’re a Windows user, but this approach works for MacOS and Linux as well. If you’re a Mac user, a better approach is to use Homebrew. Npm is a separate project from Node.js, and tends to update more frequently. As a result, even if you’ve just downloaded Node.js (and therefore npm), you’ll probably need to update your npm. Luckily, npm knows how to update itself! To update your npm, type this into your terminal: npm install npm.
Install the package from the .dmg by following along the install wizard which will install both node and npm, npm is Node Package Manager which allows for installs of additional packages for node.js.
At the end of the install you are prompted to make sure that /usr/local/bin is in your path, double check you have it by running in the Terminal:
For Node.js projects, the easiest way to install npm packages is through the npm package installation window. To access this window, right-click the npm node in the project and select Install New npm Packages. In this window you can search for a package, specify options, and install. Notice that the Cypress npm package is a wrapper around the Cypress binary. The version of the npm package determines the version of the binary downloaded. As of version 3.0, the binary is downloaded to a global cache directory to be used across projects.
After install check it was ok by entering in the command line node which will open a node javascript session:
To exit the node.js session just hit ‘control’ + ‘c’ twice.
If you have an earlier version of node you can just download the latest version and install to upgrade it and it will over write the previous version. Free scanner software for mac.
