By: Kirill Konshin

Overview of this book

Next.js is a powerful addition to the ever-growing and dynamic JavaScript world. Built on top of React, Webpack, and Babel, it is a minimalistic framework for server-rendered universal JavaScript applications. This book will show you the best practices for building sites using Next. js, enabling you to build SEO-friendly and superfast websites. This book will guide you from building a simple single page app to a scalable and reliable client-server infrastructure. You will explore code sharing between client and server, universal modules, and server-side rendering. The book will take you through the core Next.js concepts that everyone is talking about – hot reloading, code splitting, routing, server rendering, transpilation, CSS isolation, and more. You will learn ways of implementing them in order to create your own universal JavaScript application. You will walk through the building and deployment stages of your applications with the JSON API,customizing the confguration, error handling,data fetching, deploying to production, and authentication.

Commit hooks

The most common reason for failed tests on CI is when a developer forgets to run the tests locally. Code in a repository can contain bugs, that's a given, but at least it should never have bugs that could be found by tests, so running tests before a commit is a mandatory practice in lots of companies.

Let's follow this best practice. We will use a library called Husky, which can wire to Git hooks to run desired scripts.

We start with packages, as always:

$ npm install husky --save-dev

Next, we need to set scripts in package.json:

// package.json
"scripts": {
"test": "NODE_ENV=test jest",
"precommit": "npm test"

And this is it; from now on, before any commit, Husky will run your tests. So, there will be fewer surprises after pushes.
