This chapter is about improving your existing dApps and smart contracts with new techniques that will make them faster, better, and more efficient. What's interesting is that most dApps can be improved with a few tricks. You'll discover new aspects of dApp development, including creating your own oracles and backends that work with smart contracts. First, you'll start by improving your React skills, and then we'll move to the backend so that you learn how to create better centralized backends for hybrid dApps that require intensive resources to work properly. After that, we'll go back to the frontend to learn how to build stronger dApps with web3.js. To cover all the areas related to your dApps, you'll build oracles with your recently acquired knowledge about servers, which are the main components to take into consideration...
