We appreciate any help and feedback from users, you can contribute in many different ways such as simple bug reporting and feature request. Dependending on your skills you are more than welcome to develop client tools, new features or even fixing bugs.

How to build

IVA is developed in HTML5, therefore it is mainly developed in JavaScript and makes a heavy usage of HTML and CSS. It uses Grunt as building tool. IVA also requires of OpenCB JSorolla project to be built, this is a JavaScript library developed for several OpenCB web-based projects, this can be found as Git submodule in IVA.

Stable releases are merged and tagged at master branch, you are encourage to use latest stable release for production. Current active development is carried out at develop branch, only building is guaranteed and bugs are expected, use this branch for development or for testing new functionalities. The only dependency of IVA from OpenCB is JSorolla.

Prerequisites

The following technologies are needed to build IVA: Node.js, npm, Bower and Grunt.

Installing Node.js and npm

To install Node.js you can visit this link.

npm stands for node packaged modules and it is the dependency manager of Node.js.

Install Bower

After installing Node.js and npm, we can install Bower by executing the following commands with root permission:

$ sudo npm install -g bower

Install Grunt

To install grunt, run

 npm install -g grunt-cli

Cloning

IVA is an open-source project and can be downloaded either as package(tar.gz) from GitHub releases or source code by cloning the repository.

Default develop branch can be downloaded by executing:

$ git clone https://github.com/opencb/iva.git
Cloning into 'iva'...
remote: Counting objects: 624, done.
remote: Total 624 (delta 0), reused 0 (delta 0), pack-reused 624
Receiving objects: 100% (624/624), 139.37 KiB | 0 bytes/s, done.
Resolving deltas: 100% (356/356), done.
Checking connectivity... done.

Latest stable release at master branch can be downloaded by executing:

$ git clone -b master https://github.com/opencb/iva.git
Cloning into 'iva'...
remote: Counting objects: 624, done.
remote: Total 624 (delta 0), reused 0 (delta 0), pack-reused 624
Receiving objects: 100% (624/624), 139.37 KiB | 191.00 KiB/s, done.
Resolving deltas: 100% (356/356), done.
Checking connectivity... done.

After this, in both cases, you must execute the following command to fetch the JSorolla submodule (only the first time):

git submodule update --init

Go to lib/jsorolla and checkout to next-v2.0.0 branch of Jsorolla by

cd lib/jsorolla
git checkout next-v2.0.0

Build

First, you must update JSorolla dependencies, from the root folder execute:

cd lib/jsorolla
npm install
bower install
grunt

Finally, to build IVA execute:

We have to install npm packages for IVA, from the the root folder execute:

npm install

This will make npm to look at file package.json and install locally all the dependencies listed there.

To install all Bower dependencies for IVA execute from the root folder:

bower install

This will make Bower to look at file bower.json and install locally all the dependencies.

At last execute:

grunt

When completed, all compiled files will be located under the build folder.

Testing

You can copy build content to a web server such as Apache HTTP Server and open your favourite internet browser to open IVA.
