## Prerequisites

It's required to install Git, Node.js, npm,  Yarn and MongoDB.

### Update your system

```bash

$ sudo apt update

$ sudo apt upgrade

```

### Install git

```bash

$ sudo apt install git -y

```

### Open required ports

```bash

$ sudo ufw allow 27017 

$ sudo ufw allow 80

$ sudo ufw allow 443

$ sudo ufw allow 3000

```

### Install nodejs and npm

- #### Node installation on Ubuntu

  You can install nodejs and npm easily with apt install, just run the following commands.

      $ curl https://deb.nodesource.com/setup_14.x | sudo bash

      $ sudo apt install -y nodejs

- #### Other Operating Systems

  You can find more information about the installation on the [official Node.js website](https://nodejs.org/) and the [official NPM website](https://npmjs.org/).

If the installation was successful, you should be able to run the following command.

    $ node --version

    v14.15.5

    $ npm --version

    v6.14.11

###

### Install Yarn

After installing node, this project will need yarn too, so just run the following command.

    $ curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/yarnkey.gpg >/dev/null

    $ echo "deb [signed-by=/usr/share/keyrings/yarnkey.gpg] https://dl.yarnpkg.com/debian stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

    $ sudo apt update && sudo apt install yarn -y

###

### MongoDb installation

Install the latest stable version.

If Ubuntu 20:

```bash

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

```

If Ubuntu 18:

```bash

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/5.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list

```

Then continue with the following:

```bash

mkdir -p /data/db

wget -qO - https://www.mongodb.org/static/pgp/server-5.0.asc | sudo apt-key add -

sudo apt-get update

sudo apt-get install -y mongodb-org < "/dev/null"

echo "storage:

  dbPath: /var/lib/mongodb

  journal:

    enabled: true

systemLog:

  destination: file

  logAppend: true

  path: /var/log/mongodb/mongod.log

net:

  port: 27017

  bindIp: 127.0.0.1, $(curl ifconfig.me)

processManagement:

  timeZoneInfo: /usr/share/zoneinfo

security:

  authorization: enabled" > /etc/mongod.conf

systemctl enable mongod

systemctl restart mongod

systemctl status mongod

```

Now we need to create сasper user, do the following:

Open `mongosh`:

```bash

mongosh

```

Create Admin:

```bash

use admin

db.createUser(

{

user: "Admin",

pwd: "YOUR_$ECURE_P@ASSW0RD",

roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]

}

)

exit

```

Re-enter with `Admin`:

```bash

mongosh -u Admin

```

Enter your password, in our case it will be `YOUR_$ECURE_P@ASSW0RD`.

Create сasper user:

```bash

use casper

db.createUser(

{

user: "Casper",

pwd: "YOUR_$ECURE_P@ASSW0RD",

roles: [ { role: "readWrite", db: "casper" } ]

}

)

exit

```

## Install Casper World Backend

    $ git clone https://github.com/nodesguru/casper-world-backend

    $ cd casper-world-backend

    $ yarn install

## Configure the application

Create .env file and fill parameters:

- RPC=https://node-clarity-mainnet.make.services/rpc

- MongoDB parameters - could be taken from MongoDb installation section

You can find an example shown below

    

    # Casper RPC

    RPC=https://node-clarity-mainnet.make.services/rpc

    # MONGODB

    DB_USER=Casper

    DB_PASSWORD=YOUR_%24ECURE_P%40ASSW0RD

    DB_HOST=127.0.0.1

    DB_AUTH_SOURCE=casper

    

## Test the project

If you made changes in the project code, then start code testing.

```bash

yarn run test

```

Expected result: all tests are passed

## Running the project

Create service file and start the application using commands below:

```bash

echo "[Unit]

Description=Casper Job

After=network-online.target

[Service]

User=$USER

WorkingDirectory=$HOME/casper-world-backend

ExecStart=$(which yarn) --cwd $HOME/casper-world-backend/ start

Restart=always

RestartSec=1

LimitNOFILE=10000

[Install]

WantedBy=multi-user.target" > $HOME/casper-job.service

sudo mv $HOME/casper-job.service /etc/systemd/system/casper-job.service

sudo systemctl daemon-reload

sudo systemctl enable casper-job

sudo systemctl restart casper-job

```
