The new born intern

Internship diaries #1

This is the first of my monthly diaries of my internship experience at WSO2 Lanka (Pvt) Ltd.

An orientation session was carried out in the first week where we were introduced to the company hierarchy, organizational levels, rules and ethics, the products of the company and the resources available to use which can be used to improve our knowledge on the technical aspects. I personally find the culture of the company uniquely interesting where each employer is free from strict rules but everybody is genuinely passionate about what they are doing.

The products of WSO2 are open-source and they are based on the carbon kernel which serves as the core of each product. Components are integrated with the core to develop features. A product is basically a set of features assembled together to achieve a single or a set of specified functionalities.

In the first two days of the second week, project demonstrations were held from which we were asked to list our preferences. I selected the project named “Developing a data mapping tool plugin for VSCode” which was under team Developer Studio. My assigned mentor is Mr. Jasintha Dassanayaka. For the rest of the second week, I had a hands-on experience with the data mapping tool plugin for Eclipse.

The third week was spent on analyzing the source code of the data mapping plugin tool for Eclipse. The main features analyzed were the objects, their interactions, method calling sequences, file loading implementations and schema saving implementations.

The fourth week was spent on developing a static web app for data mapping tool using JavaScript. The implementations of file drag and drop, XML file parsing and the mapping functionality were mainly focused and completed successfully. To implement the mapping functionality, many libraries such as GoJS, jqTree, jsPlumb were researched but used jsPlumb due to the abundance of tutorials and community forums.

The problems faced during this period were overcome by the support of my mentor and on-line resources such as StackOverflow.
