DESCRIPTION

This is an easy guide for installation

---

NODE INSTALLATION

Node is a server-side runtime environment for Javascript. It allows us to run Javascript code on the terminal.

For Node.js 9:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

NPM

To compile and install native addons from npm you may also need to install build tools:

sudo apt-get install -y build-essential

To install Node on MAC SYSTEMS follow the Instructions from this

http://blog.teamtreehouse.com/install-node-js-npm-mac

Update Npm

I would be useful to update npm to avoid this error when deploying.

Name of your token (example: NGH Macbook): (node:8245) [DEP0022] DeprecationWarning: os.tmpDir() is deprecated. Use os.tmpdir() instead.

• To update use

sudo npm i -g npm 

Confirm Installation

npm -v 5.5.1

node -v v9.2.0

We run npm -v to check the version of Node Package Manager Installed. And node -v to check if Node is installed.

You should have node version higher than 9+ and npm 5+

To Install using Node Version Manager Which is preferable as it is always up-to date:

I will also help with installation of git and other packages.

ANGULAR INSTALLATION

Angular is a platform that makes it easy to build applications with the web.

We will install Angular CLI (Command Line Interface) that will help us create and develop our Angular apps

1. Installation

npm install -g @angular/cli

This command will install the Angular CLI.

1. Confirmation

ng

This will bring up a screen to show all the available ng commands.

WATCHMAN INSTALLATION

Watchman exists to watch files and record when they change. It can also trigger actions (such as rebuilding assets) when matching files change.

Linux Installation

cd ~

git clone https://github.com/facebook/watchman.git

cd watchman/

git checkout v4.7.0

sudo apt-get install -y autoconf automake build-essential python-dev

./autogen.sh

./configure

make

sudo make install

watchman --version

echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches  && echo 999999 | sudo tee -a  /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee  -a /proc/sys/fs/inotify/max_user_instances && watchman  shutdown-server

Mac Installation

brew update

brew install watchman

ES6 And TypeScript INSTALLATION

TypeScript is a superset of ES6. Since most browsers do not support TypeScript we have to convert it to normal Javascript. The Process of converting TypeScript to normal ES5 is called transpilation.

1. Installation

npm install -g typescript

1. Confirmation

tsc -v

JAVA INSTALLATION

To get started, we need to install the Java development kit (Java SDK) that allows us to create Java applications and the Java Runtime Environment (JRE) which provides the requirements for executing a Java application.
