Good, bad and the ugly

My experience with Medium has been a mixed bag. However, overtime, I’ve felt the need to migrate to my own blog due to certain reasons. Recently, I was able to take out some time and build my blog.

At Instawork, we’ve been using React Native for building our mobile applications using JavaScript and React. We use Redux for state management and Redux Saga for managing side effects and asynchronous things (like data fetching) efficiently.

All of these are amazing tools for building your app, however, you might end up manually writing a lot of boilerplate code depending on the way your app is structured.

In this story, we’ll be going over how you can scaffold new screens and modules using Yeoman generators. This will help your team to quickly start with new features and focus more on important…

Music is a great hobby to pursue in your four/five years at NITH and even further. Music Club is a place for all budding musicians of NITH to interact and jam with each other. Although there was once a rumor about all the girls getting selected in the auditions, you may rest assure that the era is long gone.

“Where words fail, music speaks.”

Music Club performs in various events within and outside the college. The most awaited event is Hill’ffair, the annual cultural fest of NITH. …

Authentication is an important concern when building apps. A common use case we come across when building apps is securing our API in order to accept only authenticated requests, hence preventing misuse.

In this story, I’ll be using a Todos app built with React Native and explain how to create a secure Node/Express API to handle the Create, Update and Delete operations for the app. This will let the app only allow editing of data by authenticated users. For this post we’ll assume that:

1. All users have Read access to the todos.
2. Only an authenticated user has write access for…

A todo app touches on all the important parts of building any data-driven app, including the Create, Read, Update and Delete (CRUD) operations. In this story I’ll be building a todo app with one of the most popular mobile frameworks, React Native.

I’ll be using ReactiveSearch Native, an open-source library which provides React Native UI components and simplifies building data-driven apps.

Here’s what I’ll be building in this story:

Elasticsearch is one of the most popular full-text search engines which allows you to search huge volumes of data quickly, while React is arguably the best library for building user interfaces. During the past few months I’ve been co-authoring an open-source library, ReactiveSearch, which provides React components for Elasticsearch and simplifies the process of building a search User Interface (UI).

This is the app which I’ll be building in this story:

Authentication and Authorization rules are THE MOST IMPORTANT security considerations when building a production app, yet they are often left out as a second thought. In this post, we will be building authentication (Who are you?) and authorization (Are you allowed to see this?) flows to a TodoMVC react app.

The key components that we will be using here are:

1. ReactiveSearch, a data-driven UI components library for React for building the UI views,
2. NodeJS/Express, as a middleware server for verifying authentication info and authorization flow,
3. Auth0, as a hosted authentication service,
4. Appbase.io, as a hosted database service.

Security is one of the most important considerations when building a production app, and often times it is left out as a second thought in the client-heavy apps built using React, Angular, and what not in the JAM stack.

In this tutorial post, I’ll be going over how to achieve securing a web app by creating a TodoMVC app which only allows modification on the data via a Node/Express API (which we’re going to build). All the TodoMVC app data will be stored securely in an appbase.io app.

In a previous post in this series, I wrote about implementing a…
