2. Node.js • Initially released May 27, 2009 • JavaScript runtime environment for executing JS code outside a browser • Open-source and cross platform ◦ Linux, macOS, Microsoft WIndows, SmartOS, FreeBSD, OpenBSD, and IBM AIX • Lets developers use JavaScript to write command line tools • Allows for JavaScript full stack development
3. Node.js uses • Run JavaScript on a terminal • Generate dynamic page content • Create, open, read, write, delete, and close files on the server • Collect form data • Add, delete, modify data in your database
4. Node Package Manager • Initially released on January 12, 2010 • npm is the standard package manager for Node.js • Essential JavaScript development tool ◦ Used by over 11 million JS developers • Largest single language code repository/software registry in the world ◦ 350,000+ Packages • Used by 500 of the Fortune 500 (and almost any other company with a website)
5. What is a package? • Also called a module • A directory with one or more files ◦ Must include package.json • Think of a building block that solves one specific problem really well • Many different packages can be used in conjunction to create custom solutions • Developers create packages and upload them to the npm registry for others to use
6. NPM’s Three Components • Website: https://www.npmjs.com/ ◦ Find new packages to use, set up Orgs to manage access to packages • Command Line Interface (CLI) ◦ Runs from terminal ◦ How most developers utilize npm • Registry ◦ Large public database of JavaScript software packages, and the meta-information surrounding it
7. Architecture
8. NPM Uses • Use packages from registry, or adapt them to fit your personal project • Download tools • Run packages without downloading them • Share code with any npm users • Restrict code to specific developers • Create Orgs to maintain package maintenance, coding, and developers • Form virtual teams using Orgs • Update applications when packages are updated
9. Installation • npm is automatically installed with Node.js • Can be downloaded at https://nodejs.org • Check if npm is installed:
10. Check if you are logged in If not logged in:
11. Help • Opens HTML document with specific information
