![]() ![]() You can also have a look at the Quickstart source and further dive into where NPM is needed.įootnote: there's a similar question about needing Node.js for AngularJS (1.x). This script installs the TypeScript definition files defined in typings.json Npm run postinstall - called by npm automatically after it successfully completes package installation. ![]() Npm run typings - runs the typings tool separately Npm run lite - runs the lite-server, a light-weight, static file server with excellent support for Angular apps that use routing Npm run tsc:w - runs the TypeScript compiler in watch mode the process keeps running, awaiting changes to TypeScript files and re-compiling when it sees them Npm run tsc - runs the TypeScript compiler once Npm start - runs the compiler and a server at the same time, both in "watch mode" Angular requires Node.js version 10.9.0 or later. The Quickstart guide itself actually continues to mention some more concrete reasons as well: Angular requires Node.js and npm package manager to install the Angular CLI. The ng new command prompts you with options for the generated application. You can now create a new Angular application by typing: ng new my-app my-app is the name of the folder for your application. Web Server: Serving your Angular SPA from a "real" albeit light web server prevents probably some nasty issues that come with checking your site using file:// links. To install the Angular CLI, in a terminal or command prompt type: npm install -g angular/cli This may take a few minutes to install.NPM (node package manager, is a part of node js) is a tool for installing 3rd party libraries and dependencies to our project. Step 1: Install NPM (Node Package Manager) First of all, we are going to need Node js. js, which can be done on-the-fly easily with Node.js and NPM (plus it's a way of easily getting typing files) Now let’s see how to install our first Angular App by using the CLI step by step. ![]() ts, and you need to run a compiler step to get them into. ![]() Here's the main reasons I speculate are behind this choice:ĬLI: Since a while now the de facto way to build and develop new Angular apps is to use the CLI tooling which relies on Node and NPM as well. Technically, Node.js and NPM are not needed to do Angular2 work. ![]()
