Navigation in web applications
How can you find what you want? Let's look at navigating around a code base.
Rider provides loads of ways to navigate efficiently across your codebase, and the IDE itself. Let’s take a look at some of them.
Use the sample code (ZIP file with 3 projects) that was created using
npx create-react-app, and open it in Rider.
I want to find the
App.js file in it. I could open the Solution tool window and look for
App.js, but if I had a large codebase, it would take longer than I want it to. Instead, I’m going to press Shift+Shift and look for that file using Search Everywhere.
Search Everywhere lets us find any file, action, class, or symbol, and shows all the matches in one place. If you want to see only files or actions in the search results, you can press Tab and switch to the tab that you need.
Now that I’ve opened the file, what else can I do with it? First, I can find a specific piece of information in it and jump straight to it using Cmd/Ctrl+F.
For a larger-scale search, targeted in part of my project such as the
src directory, I can use the Find in Path functionality. I can look in the selected subdirectory, entire project, module, or in a specific scope.
This Find in Path menu has many useful ways to narrow down your search: case sensitive, file name filters, regular expressions, and more.
At the bottom, you can have a quick peek into files without opening them in the editor.
Let’s say I want to check where a symbol was declared or look for its usages. I can focus on that symbol and click Cmd/Ctrl+B and voila! The file opens with the cursor on the definition of the symbol.
Now, what if I want to go back to a file I recently opened? There’s the Recent Files popup that can help with that (Cmd/Ctrl+E). On its right, you can see the list of recently opened files that you can quickly jump to. On the left, there’s a list of tool windows. Let’s use the speed search to narrow the list of choices and explore one more helpful navigation feature.
The Structure tool window can be very handy for examining a file quickly. It provides an overview of its structure and lets you jump to a specific item by simply typing its name.
