VS Code uses the TypeScript language service for its JavaScript code intelligence and it has a feature called Automatic Type Acquisition (ATA). , you see the types and methods on the object through IntelliSense. You'll notice that VS Code has syntax highlighting for the various source code elements and, if you put the cursor on a parenthesis, the matching bracket is also selected.Īs you start typing in index.js, you'll see smart suggestions or completions.Īfter you select a suggestion and type. Now expand the src folder and select the index.js file. You'll get nice formatting, hyperlink navigation to headers, and syntax highlighting in code blocks. You can open the preview in either the current editor group ( Markdown: Open Preview ⇧⌘V (Windows, Linux Ctrl+Shift+V)) or in a new editor group to the side ( Markdown: Open Preview to the Side ⌘K V (Windows, Linux Ctrl+K V)). A nice way to review the README is by using the VS Code Markdown Preview. This has lots of great information about the application and React in general. In the File Explorer, one file you'll see is the application README.md Markdown file. To open your React application in VS Code, open another terminal or command prompt window, navigate to the my-app folder and type code. ![]() We'll leave the web server running while we look at the application with VS Code. You should see the React logo and a link to "Learn React" on in your browser. Let's quickly run our React application by navigating to the new folder and typing npm start to start the web server and open the application in a browser: cd my-app npm start Note: If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version.

To use the generator as well as run the React application server, you'll need Node.js JavaScript runtime and npm (Node.js package manager) installed. We'll be using the create-react-app generator for this tutorial. The Visual Studio Code editor supports React.js IntelliSense and code navigation out of the box. React is a popular JavaScript library developed by Facebook for building user interfaces. Configure IntelliSense for cross-compiling.This means that they "override" other style rules that may be applied to an element. Style applied directly to the elements as compared to styles in a stylesheet also have higher precedence. ![]() Styling elements inline doesn't require you to create a separate stylesheet. Inline styles are the most direct away to style any React application. Want to code along with each of these examples? Go to react.new to create a new React application instantly ✨ Inline Styles ![]() ![]() To see how the code for each of these styling approaches compare with one another, we will create the same example: a simple, but clean testimonial card. Let's get started! What We Will Be Coding That's why at the end of each section, I will cover the pros and cons of each approach to help you choose which is the best for you in your projects.
