-
browser makes a requests to server to access "/about" particular path and server resolve that request and then provide required content to client side
-
server refreshes entire page but client side doesnt
-
it will request data thats needed for current page not less not more
-
deployment is easier but it should be optimized
-
if any particular path is not find it will render index.html and so along with index.html + client side JS history object provides content required.This is case when url is typed in url bar
-
in case of any button click navigation request for resource is not done at each navigation button rather history will keep track of address in browser and then react Router will decide which path to be render ie "/" or "/about" or "/skills" etc
-
Routing is handled internally by client side JS
-
No page reload between different views
-
redundant component dont need to be loaded again and again like header/footer/nav
-
required more time at initial setup and load time and can affect search engine result
Types of Routers :
- Browser Routers which we used using component eg: localhost:3000/about
-
Hash Router eg: localhost:3000/#/about Everything after "#" is seen as route
-
Memory Router eg: localhost:3000 This doesnt use Url to track the routes
What are React Portals ?
React Portal is created using ReactDom.createPortal(renderable react modal component child, DOM container where we want to load our component at root level of body);
z-index -> Help us to stack one component over another like overlapping of modal component over home component
Modal Component should be at top level of components ie parent component to use it
A typical use case for portals is when a parent component has an overflow: hidden or z-index style, but you need the child to visually “break out” of its container. For example, dialogs, hovercards, and tooltips.
It is not a good idea to put modal component inside any child component rather we will put it at top level with unique Id which will be direct child of body
a) Right Way b) Wrong Way
body body

This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
