            First solution

            First, make sure your node.js version is not superior than the latest stable version(currently 16.14.0). You can check here on

            Then, to compile .scss or .sass files you should be using sass package instead of node-sass. Fo that do :

            How to reduce react app build time and understanding behaviour of webpack when bundling
            Asked 2021-Jun-05 at 18:35

            Recently I am trying to optimize the performance of a web app(React). Assuming it is somewhat heavy as it consists of Code editors, Firebase, SQL, AWS SDK, etc. So I integrated react-loadable which will lazy load the components, After that, I got this Javascript heap out of memory issue.

            FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory in React

            After some research(From a friend), I came to know that If we keep too many lazy loadings webpack will try to bundle them parallelly It might be the cause to get a Javascript heap memory issue, To confirm that I removed all Lazy loading routes in my App and built. Now build is successful. Later as suggested by the community I increased Node heap space size and got the below insights

            First I increased it to 8 GB(8192) then build is success I got build time of around 72 mins, From next time onwards I am getting around 20 mins. Then I decreased heap memory size to 4 GB(4096) and getting build success it is around 15 - 20 mins. System configuration is 2vCPU, 16GB RAM(AWS EC2 Instance r5a.large).

            Next, I kept build in another system (Mac book pro, i5, 8 GB RAM, 4 Cores) Now it took 30 mins, Second time it took 20 mins

            So from these data points, I got a couple of questions

            1. Do we need to keep increasing heap space whenever we add some code? If yes what would be the average heap memory size in the community
            2. What would be the usual configuration for build systems for these kinds of heavy apps, Why because now I am not sure whether to increase the number of cores or RAM or Heap space or Altogether something to do with our app code.
            3. Do webpack provide any kind of solutions to avoid heap memory issue like limiting parallel processes, or any plugins?
            4. If at all it is related with our App code, Is there any standard process to debug where it is taking memory and to optimize based on that

            PS : Some people suggested to keep GENERATE_SOUCREMAP=false it got worked but we need source maps as they will be helpful in debugging production issues



            Answered 2021-Jun-05 at 10:34

            Finally, I could resolve the heap out of memory issue without increasing heap memory space.

            As mentioned in the question If I remove all Lazy routes build is getting successful Or I had to keep 4GB Heap space to get it success with plenty of build time. When the build is success with 4GB Heapspace I observed that nearly 8 - 10 chunk files sizes are nearly 1MB. So I analyzed all those chunks using Source map explorer. In all chunks almost same libraries code is included (In my case those are Firebase, Video player, etc which are heavy)

            So In my assumption when webpack is trying to bundle all these chunks It had to build all those libraries dependency graph in every chunk which in turn causes heap memory space issue. So I used Loadable components to lazy load those libraries.

            After lazy loading all those libraries all chunks files size is reduced almost by half, And Build is getting success without increasing any heap space and build time also got reduced.

            After optimization if I keep build in 6vCPU , i7 System it is taking around 3 - 4 minutes and I observed that based on the number of Cores available in the system build time is getting reduced. If I keep build in 2vCPU system it is taking around 20 - 25 mins like that sometimes

            How do I implement Sibling Component communication in App shell and SSR
            Asked 2020-Sep-25 at 12:21

            I have adopted a project that was built on this starter kit. This architecture employs App Shell and SSR. I am trying to add a simple search bar and this will mean passing the search keys from the search bar component to the post-list component so they can be filtered. I have found that this is nearly impossible with Context Providers and Consumers. I would like to use Context, but I do not know how to do it. It looks like this starter kit has this as a serious shortcoming and if it could be solved, it would make this kit more useful online.

            If you look at the code below and in the link above, you can see that there is a header center and then thee are pages. I need a communication between the header and the pages. You can just use the code in the link to add the sibbling communication.

            The use of Hydrate seems to preclude the simple application of a context provider. Hydrate adds components in a parallel way with no way to have the Context Provider above both of them. This pattern I am using here does not work. When I update the provider it does not cause a re-render of the context consumer.

            If I have to use something other than Context, like say Redux, then I will accept that answer.

            Here is the client entry point:

            You can create a Context, lets'say AppContext



            How to run my react app in Docker container
            Asked 2020-Sep-18 at 09:26

            I have this react app I want to dockerize. But the problem is, even though I tried, it doesn't work. But it works pretty well locally

            This is how the current directories look like:



            Answered 2020-Sep-18 at 09:09

            Firstly, make sure you are copying the same package-lock.json file that you use to install deps locally, to make sure you have the same dependency tree in your container as you do locally.

            COPY package.json package-lock.json /app/

            Then, make sure that you are matching the same node/npm version as you run locally (replace 12 with the major version you are running, be it 10, 12, 14 or whatever):

            FROM node:12

            Each node version is bundled with a specific npm version (latest 12 version comes with npm 6.14.6), you can find the bundled NPM version int he changelogs,

            Additionally, instead of running npm install, you might wanna run npm ci in the container. The latter skips any checks for discrepancy between the lock file and your package.json file and just installs the locked dependency tree, which is not only faster, but will also match your local dep tree exactly.


            In addition, this line:

            COPY . /app

            Would also overwrite node_modules unless you have ignored it via .dockerignore or similar.

            Easiest would probably be to add a .dockerignore file to the same folder as your Dockerfile and add lines stating:

            Answered 2020-Jul-30 at 14:16

            If your build takes longer than 10m without output this will happen.

            You can use travis_wait to print something to the console each minute, as per the docs:

            Just travis_wait {your_command} and you should be good to go.

            Be aware that your build taking longer than 10m could be a indicator of a more complicated underlying problem/freeze.



            ReactJs : How to load react functional components selectively at startup?

            I am trying to load components only when clicked instead of loading all during startup.




            Answered 2020-Jun-17 at 12:42

            The reason all Providers are invoked is because you don't render them within a Route. The correct way to invoke components on specific routes is to render them as Route children and not as Route wrappers
