![]() set the cache cache.Paul Cowan Follow Contract software developer. Route - An object or Route Element typically with a shape of ) Route Config - A tree of routes objects that will be ranked and matched (with nesting) against the current location to create a branch of route matches. Router - Stateful, top-level component that makes all the other components and hooks work. URL Params - The parsed values from the URL that matched a dynamic segment. For example the pattern /users/:userId will match URLs like /users/123 They aren't URLs, they're patterns that React Router will match.ĭynamic Segment - A segment of a path pattern that is dynamic, meaning it can match any values in the segment. Path Pattern - These look like URLs but can have special characters for matching URLs to routes, like dynamic segments ( "/users/:userId") or star segments ( "/docs/*"). For example, "/users/123" has two segments. Segment - The parts of a URL or path pattern between the / characters. Finally, a pop happens when the user clicks the back or forward buttons in the browser chrome. A replace is similar except it replaces the current entry on the stack instead of pushing a new one. A push when a new entry is added to the history stack (typically a link click or the programmer forced a navigation). Users can arrive at a URL for one of these three reasons. ![]() History Action - One of POP, PUSH, or REPLACE. History - An object that allows React Router to subscribe to changes in the URL as well as providing APIs to manipulate the browser history stack programmatically. Client Side Routing enables developers to manipulate the browser history stack without making a document request to the server. If you click and hold the back button in a browser you can see the browser's history stack right there.Ĭlient Side Routing (CSR) - A plain HTML document can link to other documents and the browser handles the history stack itself. History Stack - As the user navigates, the browser keeps track of each location in a stack. Much like hash or search params (data encoded in the URL), but stored invisibly in the browser's memory. Location State - A value that persists with a location that isn't encoded in the URL. It's mostly an object representation of the URL but has a bit more to it than that. Location - This is a React Router specific object that is based on the built-in browser's window.location object. A lot of people use the term "URL" and "route" interchangeably, but this is not a route in React Router, it's just a URL. The rest of this guide will go into more detail on each one. Here are some words we use a lot when we talk about React Router. Sometimes a word in one context might have different meaning than another. Rendering a nested UI from the route matchesīut first, some definitions! There are a lot of different ideas around routing from back and front end frameworks. ![]() Subscribing and manipulating the history stack.We'll go into detail on the three main jobs of React Router: React Router isn't just about matching a url to a function or component: it's about building a full user interface that maps to the URL, so it might have more concepts in it than you're used to. You don't need to go this deep to use it. Please don't let this document overwhelm you! For everyday use, React Router is pretty simple. This document contains detailed explanations of all the core concepts behind routing as implemented in React Router. If you've ever had any of these questions, or you'd just like to dig into the fundamental pieces of routing, you're in the right place. How can it help you build your app? What exactly is a router, anyway? You might be wondering what exactly React Router does. It's pretty long, so if you're looking for a more practical guide check out our quick start tutorial. This document is a deep dive into the core concepts behind routing as implemented in React Router. This document needs to be updated for 6.4 data APIs
