随着React服务端渲染越来越流行，笔者也想尝尝鲜，经过半个月的折腾，笔者把原先的客户端渲染项目，通过结合 next.js 构建了一个服务端渲染的同构项目。再加上开启服务器页面缓存，以及静态资源CDN加速优化，最终使得网站首屏渲染时间在0.6秒（即：DOMContentLoaded 的时间）左右，大大提高了页面的响应速度，进一步提升用户体验。.

QUESTION
because of some issues such as having SSR, SSG, and CSR beside each other, I decided to create my own SSR for React js with express js, I'm using redux and saga, and I have several API calls to generate the data before rendering it. so I had to use several promises in my server-side renderer, such as waiting for redux to finish all APIs, or waiting for styles and scripts, also I'm using react-ssr-prepass and it navigates through all my components (for dispatching actions that are required in SSR). so I have a lot of thread-blocking stuff in my project.
for handling concurrency I started to use node-cluster, so I'll have several nodes on my server and it will increase the concurrency capacity, but it's not the best solution because, under heavy load, even node clustering won't be able to respond to all of the requests.
so I started to think about worker thread or child process in node js, so I make an instance of my server-side renderer on each request and do everything in the background, so concurrent requests won't wait for eachother to be done.
but the issue is in the child process or worker thread I can't use "import", since it's es6
so I have two questions
first of all, is there any way to use es6 in the child process? (I tried babel-esm-plugin but it's not supporting webpack 5)
second, is there any better idea than using worker thread of child process to increase the concurrency capacity?
...ANSWER
Answered 2021-Nov-12 at 07:37so I found the solution for my first challenge, instead of running my renderer directly with the child process, I had to build it first, so I used webpack to make a cjs output of it, then use that output in the child process.
and for increase the performance, even more, I used a combination of SSR and SSG, so in each request I check if a file mapped to the route exists on the server, if it's not, I'm gonna use SSR renderer output to create a file, and serve the response to the user, then for next request since the cached file exists I use that cache file instead of rendering the result again. finally I set a corn job on the server to clear the cache every 10 minute
QUESTION
I'm using next js and back4app for my web application. I came across the sitemap library to write a sitemap, but I am not able to create a dynamic site map at all. I am not able to run any api calls or cloud code, I have a specific function which will return all the routes so that I can pipe them. Here is my sample code below:

I'm using react-redux in my next js application. I'm calling the request to create a store when there is a request in my _app.js but there is some message logged in my console every time I route to a page.
I feel this is a bit annoying, I've search all over my code but I can't find what is logging here. Here is my _app.js for reference.

I have very short code, where I am trying to use https://github.com/lfades/next-with-apollo , next-with-apolo. But the SSR does not work in my case, and I am still doing client call, maybe someone can guide me.
My with apollo ->
...ANSWER
Answered 2021-Apr-09 at 14:23The request is being called on client side cause you have written const { data } = useQuery(QUERY); in Profile Component. So when component is rendered on client side then that query is called.
If you want to call that query only on server side i.e ssr then use getServerSideProps method and in that call the given query and pass the result as props to the Profile Component
Example:

I am trying to do SSR for a React App made with Redux, Saga, and ConnectedRouter. I found a couple of relevant examples, specifically https://github.com/mnsht/cra-ssr and https://github.com/noveogroup-amorgunov/react-ssr-tutorial

I'm trying to parse a markdown table using react-markdown and rendering the resulting tags using the Material-UI table component. Here's my renderer:

Answered 2020-Jul-19 at 11:34I had the same issue. I solved it by not passing all the props further down to material components.
You can see what I used to theme the markdown with material ui in the component in this gist: https://gist.github.com/boganegru/a4da0b0da0b1233d30b10063b10efa8a
QUESTION
I know there is topic on why this error occurs on here. My question is how to fix it in the NextJS environment and babel to produce chunks that don't include the spread operator in an object. Here is the background.
I need to support Edge18 where the spread operator is not supported in object destructing. It produces the error:
SCRIPT1028: SCRIPT1028: Expected identifier, string or number
The error is caused by this line:
...ANSWER
Answered 2020-Jun-12 at 15:25One of your dependencies is not using ES5-compliant code for older browsers and will need to be transpiled.
You need to narrow which dependency is producing this code and transpile it using babel. This dependency can be the result of a sub-dependency to a main dependency, so you may have to traverse the entire dependency tree all the way down to find the culprit. A simple example would be: @nivo is a React charting package that has a sub-dependency called d3-scale which dropped support for IE11 and can't be polyfilled, therefore it needs to be transpiled by babel to work in IE11:
next.config.js
QUESTION
My Next JS website was working perfectly, one day when I tried to install Apollo Rest from here https://www.apollographql.com/docs/link/links/rest/#gatsby-focus-wrapper I began having a lot of errors. I discard any changes in packages.json, removed packages-lock.json, node_modules and dust file and folders. But keep getting the next error:
...ANSWER
Answered 2020-May-17 at 21:23I found where is the problem, one of my websites link getting undefined value. I am using 'next/link' component. But it's not logical to get all these three exceptions for an undefined URL passed to that linked. I think NextJS development team should review more how they are logging an exception. And even if I passed undefined for that component, there should be a check for that, not the whole website should go down.
QUESTION
I have simple running react Server Side App .
GitHub Link for the repo, in the local env i have a build script that runs using npm start which starts the client and server builds and then i have a watcher which listen's to changes in file. This set up works really well locally.
...ANSWER
Answered 2020-May-17 at 03:25I am not using heroku cli and not planning on using it
You should and I really recommend, as it's the best way to see errors that occurs after the build, why your app crashed and see the full logs. Even though you can see the logs from your heroku dashbord (More -> View logs), this only gives you the tail of the logs.
How can we make sure this small React SSR git repo deploys and i am able to access the home page.
Make sure the server is listening on the right port
by using process.env.PORT as heroku expose a dynamic port.
