Recently, I had to create a AWS Lambda trigger for the AWS DynamoDB table events. The tricky part on this thing was to mutate AWS GraphQL using AWS Lambda with this DynamoDB event. The reason was I wanted all the clients which were subscribed to GraphQL to get this event with modified data.
Recently I came up with a react native app which needs to integrate AWS GraphQL. Its actually provided with AWS App Sync and a very convenient way if you want a quick pub-sub. The problem was I had to do mutations as a background asynchronous process and wanted to update the app state from that. When I went through the documents I found the AWSAppSyncClient which is an Apollo Client. Although it was promising the react native examples were more focusing towards react or react-native Components which was really making a mess.

Recently I got the opportunity to use DatePicker of antd library https://ant.design/components/date-picker/ for a react.js project. It was really cool to use that until I found it was using the whole antd library to import this single antd components. It wasn’t right and there was a solution introduced by the antd team. I just blogged it for anyone who will find it interesting. Read more “How to use antd components without the whole library”
In this post, I would like to share a Modular Approach to create API generated with express.js. The modular approach which discussed here is having a module which can perform each and every task relevant to the API. It has following features.

There are some instances where you need to debounce and avoid multiple clicks/taps on a button so that it will not generate the same action chain immediately with a consecutive click. An example would be an application with a touchscreen. If you click a button rapidly, that event will be generated more than once. As a solution, most of the time devs would block the UI until the action chain is completed. But this would be a bad experience if the user is blocked for any other interactions. A typical example can be a fetch call to update the state and if the invocation is asynchronous it could be causing more inconvenience.
This guide will take you through on how to use nodemon to build api which is simply to create a web app with node.js + express.js in a babel environment. Often we need to use babel to increase readability of our code. And nodemon was used to watch and re-build the project and serve it consistently.

Recently I happened to create a middle panel where different types of components could be rendered on top it. So the idea is, the panel should be a <div> wrapper around the middle content. For this kind of situation, higher order functions with components could come in handy to use. Read more “Higher order component wrappers using React.js and reusable components.”
This guide will simply cover to embed SASS support in React.js project.
First, install node-sass and sass-loader npm packages.
Yarn: yarn add sass-loader --dev yarn add node-sass NPM: npm install node-sass npm install sass-loader --save-dev
