To become a better React developer, you don't always have to learn an entirely new, challenging skill. You can instantly improve your React code in a few minutes by using the powerful features your development tools make available.
Some of the biggest improvements in your work as React developer take the smallest amount of time to learn. Make an effort today to apply these tips and I guarantee you'll save many hours of tedious work in your daily coding, plus enjoy coding with React much more.
Here are five shortcuts that you can take advantage of right now to become a more productive React coder.
These tips largely feature how to get more out of your code editor. The code editor I use is Visual Studio Code, which is very popular among React developers. If you want to use VSCode, you can download it for free at code.visualstudio.com. Note that these features are available in virtually all code editors.
As a React developer, you write a lot of JSX elements, most of which consist of an open and closing tag.
If you don't have Emmet setup with React, you have to write both of these tags by hand for every element. A far better approach is to use a tool called Emmet, which automatically creates the closing tag whenever you create the opening one.
To setup Emmet with React in VSCode:
- Go to Code (at the top of your screen), then Preferences, then Settings in VSCode
- In the options on the left, select Extensions, then Emmet
And just like that, Emmet has sped up your coding by 100%:
Can you count the number of times your code hasn't been aligned probably so you tried to adjust the spacing yourself? I don't want to even think about how much time I've spent formatting my own code!
If you're still trying to format your code manually, you need Prettier.
Prettier is aptly named: it turns your misaligned code into a much prettier, formatted version.
Here's how to setup Prettier to use across all your projects in VSCode:
- Go to Code, then Preferences, then Extensions
- Search for prettier in the search input and hit enter (it should be the first one to come up)
- Select the extension, then hit Install (and possibly Reload to apply the extension)
- Go to Code, then Preferences, then Settings
- Search for Format on Save and select the checkbox next to the format on save option
Now all of the code you write will be formatted perfectly, every time you save:
Do you get tired of having to do this? We all do. That's why snippets for React exist.
To avoid all the extra work of writing the same code again and again, use React snippets. Snippets allow you to use keyboard shortcuts to instantly write every part of your React code instead of having to type it all out manually.
For example, instead of writing
import React from 'react' you can just write
imr and hit the Tab key to instantly create the same thing. Snippets are a huge timesaver.
Here's how to use React Snippets in VSCode:
- Go to Code, then Settings, then Extensions
- Search for React Snippets. There are many good snippet extensions to choose from.
- When you have a snippet extension installed, take a look at the shortcuts available and write the best ones down.
- When you type a shortcut, wait for the suggestion to appear in your code editor and then hit Tab (you can arrow through the list if you want a different one)
You'll be shocked at how quickly you can make your components now:
One of the most tedious things to do in creating React apps is importing packages and components from other files.
It's very repetitive and can take a significant amount of energy to import every single thing by hand (plus to correct when you make a typo).
Instead of having to remember, find and manually import your components and packages, let your code editor do it for you. You can** auto import** whatever you like by selecting what you want to import pressing the Tab key.
Here's how to auto import packages and components in VSCode:
- Go to Code, then Preferences, then Settings
- Search auto import and make sure the Enable Auto Import checkbox is selected
- Go back into your project, write the name of what you want to import, arrow through the options the editor suggests, and hit Tab to instantly create an import statement for it.
When you use auto import, it makes working projects of any scale easier, because you no longer spend half of your time writing import statements.
Along with having Prettier for all of the code that we write, VSCode gives us a shortcut called organize imports that does just that. In fact, it does two things:
- It alphabetically organizes our import statements
- It removes unused import statements (instantly fixes linting warnings about unused imports)
And best of all, this shortcut requires no setup. Here's how to use it:
- Go to View, then Command Palette.
- Search for organize imports and select it.
- Your imports should now be organized and any unused imports removed.
Note that you can use the keyboard shortcut
command/control + shift + o as well.
