Mean Idea
Our opinionated take on a MEAN stack (MongoDB, Express, Angular, Node) – modeled on Mean.io. We added a few handy features that we found ourselves repeatedly using. This comes from our deep experience in Node.js and related server-side JS tech.
Mean Idea Rel
Very similar to our Mean Idea. The only difference is that we replaced MongoDB with a Relational Database. Again, this is something we found ourselves repeatedly using, so we thought others might find it useful.

IdeaCrawler
IdeaCrawler is a blazing fast, highly effective, flexible client-server crawling framework written in Go. We built it to perform certain tasks better than existing crawlers. Based on the tests we conducted, we found that our crawler outperformed Scrapy and several other alternatives, many times over.
In addition to the features you would expect from a regular crawling library, IdeaCrawler makes it very easy to do things like scaling across machines, crawling through VPNs, using cookies, using Chrome as a crawling backend, etc. It was written to act as a layer on top of a regular crawling library, with a lot of pre-written glue code.
This framework also allows users to isolate crawling to a dedicated cluster, while still being controlled from a central location.

ReactJS + Sails + Redis (RSR)
Sails and React.js are fast becoming popular alternates to Node.js and Angular.js. RSR is a start application that integrates React with Sails. As an added bonus, Redis is configured as the primary database.

Cordova AES256 Encryption and Decryption
This Apache Cordova Ionic plugin allows you to perform AES 256 encryption and decryption on plain text. It’s a cross-platform plugin that supports both Android and iOS. The encryption and decryption are performed on the device’s native layer, so the performance is much better. The entire operation is performed in the background thread.

NebTest
NebTest will automate unit testing of Nebulas smart contracts. It enables you to:
- Automate smart contract testing on both testnet and mainnet
- Run test case with multiple test data sets at the same time
- Run test cases in a clean state, by deploying a smart contract before each test case

Hyperledger Fabric Bootstrap
This project gives you a framework for setting up a hyperledger fabric v1.1.0 network on multiple VMs. We are using Vagrant with libvirt/KVM to create VMs. Other setups will work too, with some changes to the Vagrantfile.
Expression Builder
Pretty much in every enterprise application we build, we find ourselves needing a query / expression builder with a nice modern UI. Since we didn’t find a good open source component for this, we decided to roll out our own.
To make it reusable, we designed it in a manner it can be easily bolted on any DB or for that matter on an entity model in any language.
The schema/entity definitions are read as JSONs and the generated expression is also written as a JSON.

Loopback for API + Isomorphic + React Router + Flux
Loopback by default comes with Angular. This is a Loopback starter app if you want to use React with it.
We have also added our usual tools-of-the-trade like ESLint as a linting tool for javascript and eslint-plugin-react for JSX.

ML Ops using SageMaker
This Experiment was carried out keeping in mind the complexity behind managing multiple ML Models in production, and a rationale behind how MLOps helps solve this problem. The code will help you to get started with implementing the MLOps process in AWS SageMaker. The implementation part can be done through the AWS console as well as the Jupyter Notebook inside a SageMaker Environment.

CCAvenue for VirtueMart
VirtueMart is an open-source extension component provided in Joomla for e-Commerce solutions. It has a few built-in payment gateway integrations, but sorely misses one with CCAvenue. This plugin bridges that gap by enabling the CCAvenue payment gateway integration for VirtueMart.

Enhanced MLFlow – Pytorch Integration
MLflow is a popular MLOps tool to manage a machine learning lifecycle but lacked support for Autologging parameters, metrics, and artifacts related to a PyTorch deep learning workflow. We worked closely with the Facebook AI Research (FAIR) team to add Autologging and provided support to load the native TorchScript models. We thereby enabled the saving of extra files and additional artifacts. These features were released in MLFlow version 1.12.0.

MLFlow – Torchserve Deployment Plugin
We worked on an experimental version of the MLflow-TorchServe deployment plugin (MLflow-TorchServe 0.0.1.dev0), which would enable developers to use MLflow to deploy models built and trained in the MLflow pipeline into TorchServe without any additional effort.

Generator Feathers Plus
We use Feathers+ in projects for developing the API layer. It provides a system-agnostic way of interacting with various databases by representing them as JSONs. The JSONs are validated using a JSON Schema. We noticed that the JSON Schema was not updated recently and it was preventing us from using some new features. We raised a Pull Request amending the JSON Schema to support new features and it was immediately accepted.

CASL
CASL is an isomorphic authorization JavaScript library which restricts what resources a user is allowed to access. All permissions are defined in a single location, without being duplicated across UI components, API services, and database queries.

Feathers-Mongoose
MongoDB is a widely used database. In a project, we used Feathers-Mongoose, an Object Document Mapper (ODM) for MongoDB. In the second quarter of 2018, MongoDB added support for database transactions. However, this new feature could not be leveraged using Feathers-Mongoose. So, we made the necessary code changes and raised a Pull Request. After a review process, it was accepted and merged to the codebase. It was later released as v7.1.0.

FormIO
We used the open-source FormIO plugin for dynamically generating forms in an application. While using FormIO for file uploads, we faced a limitation; we were unable to send in custom headers as part of the request URL.
There were hacky workarounds to solve this issue in the backend. But, the ability to use custom headers is a common use case. So we requested FormIO to have an optional configuration wherein custom headers could be keyed in as a JSON. We also raised a Pull Request with changes and it was accepted and merged by the FormIO team. Thanks to this, coders can now add custom headers to URL requests in FormIO, using this new optional configuration.

ModelMapper
The goal of ModelMapper is to make object mapping easy, by automatically determining how one object model maps to another. In the same way a human would, while providing a simple, refactoring-safe API for handling specific use cases.
The existing model mapper did not support “java.util.Date” conversion. We fixed this, so the conversion worked for the date datatype too.
