IVIS-CORE

Introduction

IVIS-CORE project provides core components, and modules in order to develop and realize modern Web applications for data visualization, and analytics.

IVIS is a framework built on Node.js (for server-side) and ReactJS (for client side). It uses mysql for long-term data storage and ElasticSearch for complex queries over time-series data. On the client, it uses the D3 library to build complex fully custom interactive visualizations.

In particular, this project offers the visualization components (LineChart, AreaChart, OnOffAreaChart, PieChart) and other core functionalities at the client- and the server-side for the development of domain-specific applications through IVIS extensions.

Structure

This project consists of the client-, and the server-side modules. The client module provides all components (UI components, visualization), libraries, etc. that will be presented to the users of Web applications through Web browsers. While the server-side module provides all components, services, and libraries to operate security, database, searching, indexing, etc.

Technologies

IVIS-CORE has been realized on top of several technologies, in particular based on JavaScript ecosystem, as the following:

• Frontend: -- User Interface: Reactjs (a javascript library) -- User Interface Design: bootstrap -- Visualizations: D3 (a javascript library) -- JSX:
• Backend: -- IVIS routes, and API: NodeJS -- Database: MySQL -- Indexing & Searching: ElasticSearch -- Security: Passport

Quick Start

Preparation

The project creates three URL endpoints, which are referred to as "trusted", "sandbox" and "public". This allows IVIS to guarantee security and avoid XSS attacks in the multi-user settings. The function of these three endpoints is as follows:

• trusted - This is the main endpoint for the UI that a logged-in user uses to manage lists, send campaigns, etc.
• sandbox - This is an endpoint not directly visible to a user. It is used to host user-defined panels.
• API - This is an endpoint for subscribers. It is used to host subscription management forms, files and archive.

The recommended deployment of IVIS is to use 3 DNS entries that all points to the same IP address. For example as follows:

• ivis.example.com - trusted endpoint (A record ivis under example.com domain)
• sbox.ivis.example.com - sandbox endpoint (CNAME record sbox.ivis under example.com domain that points to ivis)
• api.ivis.example.com - public endpoint (CNAME record api.ivis under example.com domain that points to ivis)

Installation on fresh CentOS 8, CentOS 7 or Ubuntu 18.04 LTS (public website secured by SSL)

This will setup a publicly accessible IVIS instance. Endpoints trusted and sandbox will provide both HTTP (on port 80) and HTTPS (on port 443). The HTTP ports just issue HTTP redirect to their HTTPS counterparts. The API endpoit will be available only via HTTPS.

The script below will also acquire a valid certificate from Let's Encrypt. If you are hosting IVIS on AWS or some other cloud provider, make sure that before running the installation script you allow inbound connection to ports 80 (HTTP) and 443 (HTTPS).

Note, that this will automatically accept the Let's Encrypt's Terms of Service. Thus, by running this script below, you agree with the Let's Encrypt's Terms of Service (https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf).

1. Login as root. (We had some problems running npm as root on CentOS 7 on AWS. This seems to be fixed by the seemingly extraneous su within sudo.)

   sudo su -
   

2. Install GIT

   For CentOS 8 type:

   dnf install -y git
   

   For CentOS 7 type:

   yum install -y git
   

   For Ubuntu 18.04 LTS type

   apt-get install -y git
   

3. Download IVIS using git to the /opt/ivis-core directory

   cd /opt
   git clone https://github.com/smartarch/ivis-core.git
   cd ivis-core
   

4. Run the installation script. Replace the urls and your email address with the correct values. NOTE that running this script you agree Let's Encrypt's conditions.

   For CentOS 8 type:

   bash setup/install-centos8-https.sh ivis.example.com sbox.ivis.example.com api.ivis.example.com [email protected]
   

   For CentOS 7 type:

   bash setup/install-centos7-https.sh ivis.example.com sbox.ivis.example.com api.ivis.example.com [email protected]
   

   For Ubuntu 18.04 LTS type:

   bash setup/install-ubuntu1804-https.sh ivis.example.com sbox.ivis.example.com api.ivis.example.com [email protected]
   

5. Start IVIS and enable to be started by default when your server starts.

   systemctl start ivis-core
   systemctl enable ivis-core
   

6. Open the trusted endpoint (like https://ivis.example.com)

7. Authenticate as admin:test

8. Update your password under Account/Profile

Installation on fresh CentOS 8, CentOS 7 or Ubuntu 18.04 LTS (local installation)

This will setup a locally accessible IVIS instance (primarily for development and testing). All endpoints (trusted, sandbox, public) will provide only HTTP as follows:

• http://localhost:8080 - trusted endpoint
• http://localhost:8081 - sandbox endpoint
• http://localhost:8082 - api endpoint

1. Login as root. (We had some problems running npm as root on CentOS 7 on AWS. This seems to be fixed by the seemingly extraneous su within sudo.)

   sudo su -
   

2. Install GIT

   For CentOS 8 type:

   dnf install -y git
   

   For CentOS 7 type:

   yum install -y git
   

   For Ubuntu 18.04 LTS type

   apt-get install -y git
   

3. Download IVIS using git to the /opt/ivis-core directory

   cd /opt
   git clone https://github.com/smartarch/ivis-core.git
   cd ivis-core
   

4. Run the installation script.

   For CentOS 8 type:

   bash setup/install-centos8-local.sh
   

   For CentOS 7 type:

   bash setup/install-centos7-local.sh
   

   For Ubuntu 18.04 LTS type:

   bash setup/install-ubuntu1804-local.sh
   

5. Start IVIS and enable to be started by default when your server starts.

   systemctl start ivis-core
   systemctl enable ivis-core
   

6. Open the trusted endpoint (like http://localhost:3000)

7. Authenticate as admin:test

8. Update your password under Account/Profile
