# eShop Web SPA (Single Page Application)


## Requirements and set up


### Install NPM
The SPA application is using a newer version of NPM than the one provided by Visual Studio 2015 (npm 2.7.4 currently), so you need to install the latest stable version of NPM,like npm .

NPM is bundled with NODE.JS. Installing NPM and NODE is pretty straightforward by using the installer package available at https://nodejs.org/en/

You can install the version "Recommended For Most Users" of Node which at the moment of this writing was v6.9.3 LTS and comes with a newer version of NPM.
You can see your initial NPM version and the installed NPM version with the command 
<b>npm -v</b>, as shown below.

### Set NPM path into Visual Studio
NPM will be usually installed under this path:
<b>C:\Program Files (x86)\nodejs</b>.
You need to update that path in Visual Studio 2015 under the "External Web Tools" location paths, as shown below:

### Build the SPA app with NPM
Finally, you need to build the SPA app (TypeScript and Angular based client app) with NPM.
* Open a command-prompt window and move to the root of the SPA application (src\Web\WebSPA\eShopOnContainers.WebSPA)
* Run the command <b>npm run build:prod</b> as shown below:

If you get an error like <b>"Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 6.x"</b>, then run the command <b>npm rebuild node-sass</b> as in the following screenshot:

Then, run again the <b>npm run build:prod</b> command that should finish with no errors.

### Build/create the Docker images
