What Is Next.js?

Question: Are Subsequent Pages Also Crawl-able (SEO) When We Change Route In NextJs Application?

Answer : 1

Is This About Page SEO-friendly? (because It’s Not HTML File),If Not, Then Does It Mean Only Initial Page Is Good For SEO And Not Subsequent Routes?,So Overall The NextJs Routing Is SEO-friendly, No Matter How It’s Crawled.

When You Use The next/link Component, E.g.

<Link Href='/about'>About Us</Link> 

then The Resulting Markup You See From The Server Side Render Will Be

<a Href="/about">About Us</a> 

Answer : 2

My Components Are Nested Like This:

 <Layout> // Loading Screen Here <Navbar /> <Main>{children!}</Main> // NextSeo Here </Layout> 

The Loading Screen Is In <Layout /> But My <NextSeo /> Implementations Are In <Main />. Here’s My Loading Code In Layout:

 If (user && User.loading) Return ( <Loading /> ); 

In My Case, I Kind Of Deprecated The User Loading Thing And Was Able To Replace It With this Solution:

 Const Router = UseRouter(); Const [pageLoading, SetPageLoading] = UseState<boolean>(false); UseEffect(() => { Const HandleStart = () => { SetPageLoading(true); }; Const HandleComplete = () => { SetPageLoading(false); }; Router.events.on("routeChangeStart", HandleStart); Router.events.on("routeChangeComplete", HandleComplete); Router.events.on("routeChangeError", HandleComplete); }, [router]); 

It Turns Out, I Was Wrong. We can Use GetServerSideProps With Dynamic Paths. So Instead Of This:

export Async Function GetStaticPaths() { Return { Paths: [], Fallback: True, }; } Export Async Function GetStaticProps({ Params }: { Params: { Id: String } }) { Let Item = Await ( Await Fetch( `/api/content/?id=${params.id}` ) ).json(); Return { Props: { Item }, Revalidate: 86400, }; } 

I Now Do This:

export Async Function GetServerSideProps({ Params, }: { Params: { Id: String }; }) { Let Item = Await ( Await Fetch( `/api/content/?id=${params.id}` ) ).json(); Return { Props: { Item }, }; }

Once That Page Mounts, React Kicks In And Enables You To Do Whatever You Want. Whether It’s Providing Simple Things For The Visitor To Interact With Or Providing Some Routing Mechanism To Change Pages, In This Example, That Entire Experience Originated From That Single Page.,When Receiving That Parameter Value, We’re Defining A Simple Title And ProductId, Which Will Be Passed In As Props To Our Page Component.,This Works Wherever The Website Or Application Is Compiled From, That Server Or Environment Will Bring In Any Data Sources And Use React To Build The Website Just Like It Would Inside The Browser, But Export It Into An HTML File. This File Would Then Get Served To The Visitor.

Client-side Transitions Between Routes Can Be Enabled Via The Link Component Exported By Next/link.,For An Example, Consider A Pages Directory With The Following Files:,The Default Behavior Of The Link Component Is To Push A New URL Into The History Stack. You Can Use The Replace Prop To Prevent Adding A New Entry, As In The Following Example:

We Can Have A Link To Each Of These Pages Like So:

import Link From 'next/link' Function Home() { Return ( <ul> <li> <Link Href="/"> <a>Home</a> </Link> </li> <li> <Link Href="/about"> <a>About Us</a> </Link> </li> <li> <Link Href="/blog/hello-world"> <a>Blog Post</a> </Link> </li> </ul> ) } Export Default Home 

For Example, The Dynamic Route pages/blog/[slug].js Will Match The Following Link:

import Link From 'next/link' Function Posts({ Posts }) { Return ( <ul> {posts.map((post) => ( <li Key={post.id}> <Link Href={`/blog/${encodeURIComponent(post.slug)}`}> <a>{post.title}</a> </Link> </li> ))} </ul> ) } Export Default Posts 

If The Child Of Link Is A Custom Component That Wraps An <a> Tag, You Must Add passHref To Link. This Is Necessary If You’re Using Libraries Like styled-components. Without This, The <a> Tag Will Not Have The href Attribute, Which Might Hurt Your Site’s SEO.

import Link From 'next/link' Import Styled From 'styled-components' // This Creates A Custom Component That Wraps An <a> Tag Const RedLink = Styled.a` Color: Red; ` Function NavLink({ Href, Name }) { // Must Add PassHref To Link Return ( <Link Href={href} PassHref> <RedLink>{name}</RedLink> </Link> ) } Export Default NavLink 

If The Child Of Link Is A Function Component, In Addition To Using passHref, You Must Wrap The Component In React.forwardRef:

import Link From 'next/link' // `onClick`, `href`, And `ref` Need To Be Passed To The DOM Element // For Proper Handling Const MyButton = React.forwardRef(({ OnClick, Href }, Ref) => { Return ( <a Href={href} OnClick={onClick} Ref={ref}> Click Me </a> ) }) Function Home() { Return ( <Link Href="/about" PassHref> <MyButton /> </Link> ) } Export Default Home 

Link Can Also Receive A URL Object And It Will Automatically Format It To Create The URL String. Here’s How To Do It:

import Link From 'next/link' Function Home() { Return ( <ul> <li> <Link Href={{ Pathname: '/about', Query: { Name: 'test' }, }} > <a>About Us</a> </Link> </li> <li> <Link Href={{ Pathname: '/blog/[slug]', Query: { Slug: 'my-post' }, }} > <a>Blog Post</a> </Link> </li> </ul> ) } Export Default Home 

The Default Behavior Of The Link Component Is To push A New URL Into The history Stack. You Can Use The replace Prop To Prevent Adding A New Entry, As In The Following Example:

<Link Href="/about" Replace> <a>About Us</a> </Link> 

The Default Behavior Of Link Is To Scroll To The Top Of The Page. When There Is A Hash Defined It Will Scroll To The Specific Id, Like A Normal <a> Tag. To Prevent Scrolling To The Top / Hash scroll={false} Can Be Added To Link:

<Link Href="/?counter=10" Scroll={false}> <a>Disables Scrolling To The Top</a> </Link>

When The Crawler Is Idle, It Picks Up The Next URL In The Queue, Makes A Request, And Fetches The HTML.,The Processing Unit Extracts All The URLs Tags Mentioned On The Webpage And Adds Them Back To The Crawl Queue.,React Was Developed To Create Interactive UIs That Are Declarative, Modular, And Cross-platform. Today, It Is One Of The More Popular—if Not The Most Popular—JavaScript Frameworks For Writing Performant Front-end Applications. Developed Initially To Write Single Page Applications (SPAs), React Is Now Used To Create Full-fledged Websites And Mobile Applications.

We Could Include A Node That Looks Something Like This:

<script Id="data" Type="application/json"> {"title": "My Blog Title", "comments":["comment 1","comment 2"]} </script> 

And Parse It When The Component Mounts:

var Data = JSON.parse(document.getElementById('data').innerHTML);

You Only Need To Have Node.js installed On Your System To Begin Building Next.js Applications.You’ll Also Have To Set Up The Following Dependencies In Your Project:,In This Example, You Will Discover next-routes, An Easy Tool For Handling Both Server And Client Side Routing.,Next.js Also Has An Embedded Mechanism To Prefetch All The Related Pages To Help Speed Up Your Website And Offer A Really Fast User Experience.To Prefetch A Link, All You Have To Do Is Add A prefetch property To The Link.

  • next:
npm Install --save Next

  • Express:
npm Install --save Express

  • next-routes:
npm Install --save Next-routes

pages/index.js

import React From 'react'export Default () => <div> <p>Hello Next.js</p> </div>

routes.js

const Routes = Require('next-routes') Module.exports = Routes().add('index', '/').add('products', '/products').add('product', '/products/:uid').add('bloghome', '/blog').add('blogpost', '/blog/:uid').add('preview', '/preview').add('notfound', '/*')

server.js

const Next = Require("next")const Routes = Require("./routes")const PORT = ParseInt(process.env.PORT, 10) || 3000const App = Next({ Dev: Process.env.NODE_ENV !== "production" })const Handler = Routes.getRequestHandler(app)const Express = Require("express")app.prepare().then(() => { Express() .use(handler) .listen(PORT, () => Process.stdout.write(`Point Your Browser To: Http://localhost:${PORT}n`))})

package.json

"scripts": { "dev": "node Server.js", "build": "next Build", "postinstall": "npm Run Build", "start": "NODE_ENV=production Node Server.js"}

pages/blogpost.js:

import React From 'react'import { Link } From './routes'export Default ({ Query }) => <div> <div>Welcome To My Blogpost With A Dynamic UID: {query.uid}</div> <Link To='bloghome'> <a>Blog Home</a> </Link> </div>
