I was trying out the new features from Next.js 13 and I can't explain to myself, why Client Components still use SSR. I thought that using Client Components would result in Components that are only rendered on the client.
Can anyone explain, how that exactly works?
Thanks
Server-side rendering basically means fetching the data on the server. So when the server sends the html to the browser, it already populates the HTML, so the search crawler will see HTML with populated data so your page will be indexed higher. Once the HTML is sent down to the browser, the browser will parse the HTML and your page will have javascript interactivity, onClick, mouseOver etc. All the client components in next.js uses ssr.
But the server component is a different concept. Entire HTML is rendered on the server so any dependency used on the server will stay on the server. So your browser will not have to parse HTML and go through all javascript. so client bundle size will decrease and your app performance will increase.
I developed react js dynamic website. Now i am checking my website content of view page source not displayed my all content. only displayed default react index.html content only attached my view page source screenshot. but these two website (https://reactjs.org/ and https://www.netflix.com/in/) view page source working well. what I do my website. could you please solve issues.
React is rendered on the client using JavaScript (virtual DOM) to handle the real DOM and place the HTML elements in the browser.
This is why you will see a single DIV (root) react uses to mount your whole app on.
If you want to send to the client HTML files already rendered on the server-side you'll have to use an SSR framework like Next.js, which Netflix for example uses itself.
I'm currently working through the next.js tutorial, but I'm struggling to understand the following:
The tutorial is telling me here, that clicking a <Link> element won't trigger a server request, and instead do "Client-side navigation", i.e. adjusting the page content with js:
The Link component enables client-side navigation between two pages in the same Next.js app. Client-side navigation means that the page transition happens using JavaScript
Three questions right away:
This sounds like regular SPA react routing without next.js etc. to me. But it isn't, right?
The <Link> still works if I disable javascript in Chrome dev tools. This shows that the transition is actually not happening with js. Is this a contradiction to their statement?
When I right click the page and click "view source" (in Chrome) I get different HTML before and after clicking the <Link>. (Contratry to the "regular" react behavior). How can this be considered "Client-side navigation"?
Going further in the tutorial, they tell me here:
By default, Next.js pre-renders every page. This means that Next.js generates HTML for each page in advance, instead of having it all done by client-side JavaScript
This statement sound like a contradiction to the other one quoted above. Can you help me to clarify this? When I click the <Link> what exactly is happening? Is a new html file loaded? If so, how can this happen "client side". Thank you!
Here is how I understand it:
The approach Next.js takes for client-side navigation is a mixture of SPA-style navigation and traditional navigation
In SPA-style navigation, a "link" is a component with some JS logic. It does not have a <a> element. When you click on it, some JS will run to render the new page. If you disable JS then you can't navigate to a new page;
In traditional navigation, a link is really a <a> element. If you click on it, then the browser will discard the current page and load the new page entirely. If you disable JS then you can still navigate to the new page;
In Next.js navigation, a "link" is a component with some JS logic, but it also has this <a> element under the hood. When you click on it, some JS will run to render the new page and prevent the default <a> navigation. So even if you disable JS, you'll still be able to navigate in a traditional fashion through the <a> element. The pre-rendered page will be fetched and loaded. This is really useful in terms of SEO (as crawlers typically don't have JS enabled), and is the main problem Next.js wants to solve.
In short, when JS is enabled, Next.js navigation behaves just like in SPAs; when JS is disabled, it behaves just like in traditional websites.
Update:
I made a video to further demonstrate the concept: https://www.youtube.com/watch?v=D3wVDE9GGVE
There!
I think the main concept that you should be getting familiar with Next.js framework is Server Side Rendering, which basically means that all contents of a page are pre-processed in the server, that ships to the browser the files already rendered, saving resources from the client-side of an application.
By default, all of your Next.js pages are pre-rendered when you use the build command.
Next.js also has its own <Link /> component which uses the next-router module to navigate between the pages.
By default, every <Link /> component in a page tells Next.js to pre-fetch that page and it's resources ( which will also be rendered by the server on the initial request from the browser ) and be "instantly available" when you click it.
I think the main basic difference than a regular SPA is that in those, when you change pages, it takes longer because they won't be already available to you.
AFAIK:
This sounds like regular SPA react routing without next.js etc. to me. But it isn't, right?
Yes. It's like a regular SPA react routing. When user clicks on Link, it will do it in JS just like CRA.
The still works if I disable javascript in Chrome dev tools. This shows that the transition is actually not happening with js. Is this a contradiction to their statement?
This is happening because, if you disable JS, what you get is a simple <a href="..." />. ie, browser will still count it as a anchor element, click events will work as expected because it's just our old HTML.
When I right click the page and click "view source" (in Chrome) I get different HTML before and after clicking the . (Contratry to the "regular" react behavior). How can this be considered "Client-side navigation"?
Your answer lies in the next statement where:
By default, Next.js pre-renders every page. This means that Next.js
generates HTML for each page in advance, instead of having
it all done by client-side JavaScript
ie, when you "View source" browser will hit the server and show you the HTML. Since Next prerenders, it will be different for different pages. This has nothing to do with client navigation. This behaviour of showing browser response in view source can vary from browser to browser though.
I am trying to add server side rendering with separate root html files to my angular-meteor project. But, as server side rendering is not possible in angular and iron router/flow router which supports server side rendering does not play with angular but with blaze.
Please help
How can I can implement server side routing and angular ui-routing ?
Iron-Router does server and client side routing, however Flow-Router does not.
It is recommended to use Picker for server-side rendering with Flow-Router, and it's basically like an Express router, so it should work fine wit Angular-Router
meteor add meteorhacks:picker
https://atmospherejs.com/meteorhacks/picker
https://github.com/meteorhacks/picker/
It supports middleware too.
Good luck
I'm working on a project where all may work is jsp pages can i add AngularJS inside these pages , i'm also new to Angular
I work on a web project, which renders a lot of graphs and animation charts to end users. We have been using the AngularJS in the jsp for some time and this works fine for us. With jsp, one can easily determine the request context (for e.g the request context URI for another link) on the webpage. With AngularJS, we develop the json returning services on server side and process the data via angularJS directives.
