ReactJS by Example - Building Modern Web Applications with React

By: Vipul A M

Overview of this book

ReactJS is an open-source JavaScript library that brings the power of reactive programming to web applications and sites. It aims to address the challenges encountered in developing single-page applications, and is intended to help developers build large, easily scalable and changing web apps. Starting with a project on Open Library API, you will be introduced to React and JSX before moving on to learning about the life cycle of a React component. In the second project, building a multi-step wizard form, you will learn about composite dynamic components and perform DOM actions. You will also learn about building a fast search engine by exploring server-side rendering in the third project on a search engine application. Next, you will build a simple frontpage for an e-commerce app in the fourth project by using data models and React add-ons. In the final project you will develop a complete social media tracker by using the flux way of defining React apps and know about the best practices and use cases with the help of ES6 and redux. By the end of this book, you will not only have a good understanding of ReactJS but will also have built your very own responsive frontend applications from scratch.

"Now we need to define the actions types that we are going to refer to as constants at various places, such as sending the type from Actions to store, and in our store, deciding what action type has been passed to store to take appropriate actions.

//SocialConstants.js
var keyMirror = require('keymirror');

module.exports = keyMirror({
  FILTER_BY_TWEETS: null,
  FILTER_BY_REDDITS: null,
  SYNC_TWEETS: null,
  SYNC_REDDITS: null

});

"Here, we are using the https://github.com/STRML/keyMirror package to create keys and values for the object based on the keys. This will convert into object similar to below."

{
FILTER_BY_TWEETS: 'FILTER_BY_TWEETS', 
…
}

"This is handy when adding new keys to not repeat the same contents again."

"We can now start using the action constants. They represent four actions that we are going to perform, as follows:"

  • SYNC_TWEETS: This fetches the tweets for a given user

  • SYNC_REDDITS: This fetches the reddits for a give topic

  • FILTER_BY_TWEETS: This only displays...
