# Pre-Requisites

## npm modules

Make sure you have all the required Node dependencies available:

```bash
npm install -g yo gulp-cli generator-angular-fullstack
```

## MongoDB

If you're using MongoDB (which you probably are), you'll have to install it from [here](https://www.mongodb.com/download-center#community). You should then run the `mongod` process, which is in `<install_path>/MongoDB/Server/<version>/bin/`. You'll also want a `/data/db` folder somewhere for Mongo to put your database in. It would be wise to make a script to automate this command, and maybe even run this script on your computer's startup. Example:

```bash
#!/bin/bash

/var/lib/mongo/server/3.2/bin/mongod --dbpath /data/db
```

## node-gyp

`node-gyp` is a cross-platform command-line tool written in Node.js for compiling native addon modules for Node.js. You'll need it for things like `uws`.

Read through the [Installation section of the `node-gyp` readme](https://github.com/nodejs/node-gyp#installation). Basically you'll need [Python 2.7](https://www.python.org/downloads/), `make`, and a C/C++ compiler (like GCC on unix, Xcode on OS X, or Visual Studio tools on Windows). To tell npm to use Python 2.7 (if you also have a different version installed), run `npm config set python /path/to/executable/python2.7`. Here's a snapshot of the instructions from their readme:

* On Unix:
  * `python` (`v2.7` recommended, `v3.x.x` is ***not*** supported)
  * `make`
  * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)
* On Mac OS X:
  * `python` (`v2.7` recommended, `v3.x.x` is ***not*** supported) (already installed on Mac OS X)
  * [Xcode](https://developer.apple.com/xcode/download/)
    * You also need to install the `Command Line Tools` via Xcode. You can find this under the menu `Xcode -> Preferences -> Downloads`
    * This step will install `gcc` and the related toolchain containing `make`
* On Windows:

  * Option 1: Install all the required tools and configurations using Microsoft's [windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) using `npm install --global --production windows-build-tools` from an elevated PowerShell or CMD.exe (run as Administrator).
  * Option 2: Install tools and configuration manually:
    * Visual C++ Build Environment:

      * Option 1: Install [Visual C++ Build Tools](http://landinghub.visualstudio.com/visual-cpp-build-tools) using the **Default Install** option.

      * Option 2: Install [Visual Studio 2015](https://www.visualstudio.com/products/visual-studio-community-vs) (or modify an existing installation) and select *Common Tools for Visual C++* during setup. This also works with the free Community and Express for Desktop editions.

      > :bulb: \[Windows Vista / 7 only] requires [.NET Framework 4.5.1](http://www.microsoft.com/en-us/download/details.aspx?id=40773)
    * Install [Python 2.7](https://www.python.org/downloads/) (`v3.x.x` is not supported), and run `npm config set python python2.7` (or see below for further instructions on specifying the proper Python version and path.)
    * Launch cmd, `npm config set msvs_version 2015`

  If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.

## Create a new folder for your project

Make a new directory, and `cd` into it:

```bash
mkdir myapp && cd $_
```

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://awk34.gitbook.io/generator-angular-fullstack/getting-started/pre-requisites.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
