Next.js Redirect from / to another page

问题

I'm new in Next.js and I'm wondering how to redirect from start page ( / ) to /hello-nextjs for example. Once user loads a page and after that determine if path === / redirect to /hello-nextjs

In react-router we do something like:

<Switch>
  <Route path="/hello-nextjs" exact component={HelloNextjs} />
  <Redirect to="/hello-nextjs" /> // or <Route path="/" exact render={() => <Redirect to="/hello-nextjs" />} />
</Switch>

In next.js you can redirect using Router ex :

import Router from 'next/router'

componentDidMount(){
    const {pathname} = Router
    if(pathname == '/' ){
       Router.push('/hello-nextjs')
    }
}

There are three approaches.

1.Redirect on events or functions:

import Router from 'next/router';

<button type="button" onClick={() => Router.push('/myroute')} />

2.Redirect with hooks:

import Router , {useRouter}  from 'next/router';

const router = useRouter()

<button type="button" onClick={() => router.push('/myroute')} />

3.Redirect with Link:

based on Nextjs docs the <a> tag is neccessary inside the link!

import Link from 'next/link';

<Link href="/myroute">
   <a>myroute</a>
</Link>

There are some other options for serverside routing which is asPath. in all described approaches you can add asPath to redirect both client and server side.

redirect-to.ts

import Router from "next/router";

export default function redirectTo(
  destination: any,
  { res, status }: any = {}
): void {
  if (res) {
    res.writeHead(status || 302, { Location: destination });
    res.end();
  } else if (destination[0] === "/" && destination[1] !== "/") {
    Router.push(destination);
  } else {
    window.location = destination;
  }
}

_app.tsx

import App, {AppContext} from 'next/app'
import Router from "next/router"
import React from 'react'
import redirectTo from "../utils/redirect-to"


export default class MyApp extends App {
  public static async getInitialProps({Component, ctx}: AppContext): Promise<{pageProps: {}}> {
    let pageProps = {};

    if (Component.getInitialProps) {
      pageProps = await Component.getInitialProps(ctx);
    }

    if (ctx.pathname === "" || ctx.pathname === "/_error") {
      redirectTo("/hello-next-js", { res: ctx.res, status: 301 }); <== Redirect-To
      return {pageProps};
    }

    return {pageProps};
  }

  render() {
    const {Component, pageProps} = this.props;
    return <Component {...pageProps}/>
  }
}
