Chrome’s developer tools can be a powerful tool for web developers. They’re built into the browser and provide access to the most common diagnostic functions. Here’s what you need to know about Chrome developer tools.
Inspecting
Inspecting is the process of looking at the structure and content of a document. You can inspect elements, attributes, styles and more through Devtools. You can also examine the DOM tree by clicking on a component in your browser’s inspector panel or pressing F12 (or Shift + Command + I).
If you want to see how CSS works on an element or page level, then Devtools has some great tools for that too!
Console
The console is a place to write, run, and debug JavaScript code. It’s the only place you can see the output of your code.
The console looks like this:
- A line of text followed by curly braces ( {} ) that contain the output of your program. This could be anything from a simple message saying “Hello, World!” to something more informative like error messages or warnings about unexpected behaviour in certain parts of your application. You can use these messages to figure out what went wrong when things didn’t work as expected and how they might improve in future releases of Chrome Developer Tools!
Networking
- Networking
The networking panel is the heart of this tool. Here you can view your app’s network requests and waterfall diagram (see below) and track down any errors in your application.
