Experience

  • Virtual Scroll for Angular 2+ (Development)
    https://github.com/rintoj/angular2-virtual-scroll

    Angular 2 Virtual Scroll displays a small subset of records just enough to fill the viewport and uses the same DOM elements as the user scrolls.

    This method is effective because the number of DOM elements are always constant and tiny irrespective of the size of the list. Thus the virtual scroll can display endlessly, growing a list of items in an efficient way.

    This open source project is an Angular 2 compatible module that has an easy-to-use API and supports multi-columns.

  • Mongo Restifier (Development)
    https://github.com/rintoj/mongo-restifier

    Mongo Restifier is an open source Node.js project for the easy and quick build of RESTful APIs using MongoDB.

    This has easy-to-use configurations and APIs. This module supports schema based collections, advanced querying, bulk operations, and automatic history. This library comes with an in-house OAuth2 authentication module, thus making it useful for creating an end-to-end API layer.
