Virtual Scroll for Angular

Angular Virtual Scroll that 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 is always constant and tiny irrespective of the size of the list. Thus, the virtual scroll can display endlessly, efficiently growing a list of items.

This open source project is an Angular-compatible module that has an easy-to-use API and supports multi-columns. We achieved 82,000 downloads.

GQL Hook Codegen

This tool generates TypeScript types for queries/mutations written in a GraphQL project given a valid GraphQL schema. This will accelerate the front-end development by many folds. The tool can also be used as a static validator to check if the server can match the client.


A state management library for modern web applications with a unidirectional data flow and an immutable uni-state.

It is a predictable state container, just like Redux. It helps users implement a unidirectional data flow (Flux architecture) easily and elegantly without much boilerplate code. This library's main objective is to provide an implementation that has minimal touchpoints—while delivering all the benefits of Redux. StateX uses an RxJS library at its heart, promising an efficient data flow. The attachment contains examples with Angular (with and without decorators) and React (with and without TypeScript and decorators).

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.
