Overview of this book

Filled with useful React patterns that you can use in your projects straight away, this book will help you save time and build better web applications with ease. React 17 Design Patterns and Best Practices is a hands-on guide for those who want to take their coding skills to a new level. You’ll spend most of your time working your way through the principles of writing maintainable and clean code, but you’ll also gain a deeper insight into the inner workings of React. As you progress through the chapters, you’ll learn how to build components that are reusable across the application, how to structure applications, and create forms that actually work. Then you’ll build on your knowledge by exploring how to style React components and optimize them to make applications faster and more responsive. Once you’ve mastered the rest, you’ll learn how to write tests effectively and how to contribute to React and its ecosystem. By the end of this book, you'll be able to avoid the process of trial and error and developmental headaches. Instead, you’ll be able to use your new skills to efficiently build and deploy real-world React web applications you can be proud of.

Installing PostgreSQL

For this example, we will use a PostgreSQL database, so you'll need to install PostgreSQL to be able to run this project on your machine.

If you have a macOS machine, the easiest way to install PostgreSQL is by doing so with Homebrew. You just need to run the following command:

brew install postgres

Once you've installed it, you need to run the following command:

ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents

Then, you can create two new aliases to start and stop your PostgreSQL server:

alias pg_start="launchctl load ~/Library/LaunchAgents"
alias pg_stop="launchctl unload ~/Library/LaunchAgents"

Now, you should be able to start your PostgreSQL server by using pg_start or stop it with pg_stop.

After this, you need to create your first database, like so:

createdb `whoami`

Now, you can connect to PostgreSQL using the psql command.

If you get an error stating role "postgresql" does not exist, you can fix it by...
