Overview of this book

<p>Vue.js is a library to build interactive web interfaces. The aim is to provide the benefits of reactive data binding and composable view components with an API that is as simple as possible.</p> <p>This book will teach you how to efficiently implement Vue.js in your projects. It starts with the fundamentals of Vue.js to building large-scale applications. You will find out what components, filters, methods, and computed properties are and how to use them to build robust applications.</p> <p>Further on, you will become familiar with ES6, single file components, module bundlers, and workflow automation. The best way to learn to code is to write it, so there’s an exercise at the end of most of the chapters for you to solve and actually test yourself on what you have learned. You can solve these in order to gain a better understanding of Vue.js.</p> <p>By the end of this book, you will be able to create fast front-end applications and increase the performance of your existing projects with Vue.js integration.</p>

Custom filter


This is the most cumbersome part of this chapter. Assume we want to display only the famous stories (the ones with upvotes greater than 20). In order to achieve that we have to create a custom filter and apply it to filterBy. We are going to create a filter named famous which expects two parameters:

  • The array we want to filter

  • The bound which defines the amount of upvotes a story must have, in order to be considered as famous

The famous filter returns an array which contains only the objects that satisfy a condition.

If you can't keep up with this example don't worry, you will get it sooner or later, just keep reading..
