next-ssr-fallback

This library helps you to fallback to CSR more easily when using SSR to avoid Next.js app rendering failure.

Introduction

We usually use getServerSideProps in Next.js to fetch the initial properties of SSR. If the acquisition fails due to server-side network problems, Next.js will return a status code of 500, which causes our app to fail to render normally.

In order to solve this problem, we need to add the fallback logic by CSR, and obtain properties on the client again when SSR acquisition fails, so as to improve the success rate of rendering.

This library is to help you do this, it only takes a few lines of code to complete.

Supported Versions

next-ssr-fallback is tested with:

• next: ^12.0.0 and above

Installation

First, install next-ssr-fallback:

$ npm install next-ssr-fallback

# OR

$ yarn add next-ssr-fallback

# OR

$ pnpm install next-ssr-fallback

Usage

You need to make the following changes to the page components:

• rename the getServerSideProps function to getServerSidePropsOrigin
• import next-ssr-fallback and create a new SSRFallback instance

import FallbackSSR from 'next-ssr-fallback';

const fallbackSSR = new FallbackSSR({
  getServerSideProps: getServerSidePropsOrigin,
});

• modify the export of getServerSideProps by using createGetServerSidePropsFunction

export const getServerSideProps = fallbackSSR.createGetServerSidePropsFunction();

• Use higher-order component wrappers withCSR for page components

export default fallbackSSR.withCSR(PageComponent);

That's all there is to it, your page will support fallback to CSR.

Example

Here is a example recruit-pc using this library. You can refer to how to use.
