            Not able to render graphql data with react.js
            Asked 2022-Apr-07 at 06:50

            I am trying to display values from an API using apollo client, server, ReactJS and NodeJS, Below is the code to do this:





            Answered 2022-Apr-07 at 06:50

            data is not available (null) yet because it is still fetching, so to handle this, use conditional rendering with loading value.



            trying to understand async / await / sync in node
            Asked 2022-Feb-11 at 16:56

            i know this probably has been asked before, but coming from single-threaded language for the past 20 years, i am really struggling to grasp the true nature of node. believe me, i have read a bunch of SO posts, github discussions, and articles about this.

            i think i understand that each function has it's own thread type of deal. however, there are some cases where i want my code to be fully synchronous (fire one function after the other).

            for example, i made 3 functions which seem to show me how node's async i/o works:



            Answered 2022-Feb-11 at 16:56

            how would i go about making these synchronous so that the order is always A, B, C

            You've confirmed that what you mean by that is that you don't want to start the timeout for B until A has finished (etc.).

            Here in 2021, the easiest way to do that is to use a promise-enabled wrapper for setTimeout, like this one:

            I just solve this issue by correcting the RxJS version to 7.4.0. I hope this can solve others issue as well.

            Answered 2022-Jan-05 at 14:53

            Its not a breaking error, just means that some functionalities might not work as expected. As this npm WARN EBADENGINE required: { node: '>=0.8 <=9' } line shows, the required node version for this package to work as intended is between 0.8 and 9 but you have node 16.



            Api request status code different when using docker
            Asked 2022-Jan-09 at 10:24

            I'm developing an api using strapi 3.6 that I develop without docker locally and I run with docker in production.

            Locally, an endpoint that returns a 400 will become a 500 in production.

            I have been investigating the issue and when I run docker locally, I also get a 500 instead of a 400.

            I couldn't find any relevant resources, does someone have any clue why this could happen?


            The backend is deployed on AWS Elastic Beanstalk.

            What I tried:

            • ❌ requesting the load balancer directly
            • ❌ requesting the underlying ec2 directly
            • ❌ running docker locally in production mode
            • ❌ running docker locally in dev mode
            • ✅ building strapi and running the server like docker does but without docker

            All above cases gave me a 500 instead of the expected 400, except for the last case that returned a 400 as expected.

            The error displayed in the logs are the ones expected. Only the way the error is returned by the api changes.

            Here is the code of the middleware that handles errors globally:

            Looking at the logs, I saw that in production I had this line returned by the api:

            The problem seems to be that of an inappropriate installation. The go to way to fix this would be to ensure a proper uninstall of node and npm. Please follow the steps mentioned here. Once properly uninstalled, head over to install node and proceed with the re-installation.

            How can I dynamically choose which MySQL server to point to?
            Asked 2021-Dec-01 at 23:48

            TL;DR: Vertical or Horizontal scaling for this system design?

            I have NGINX running as a load balancer for my application. It distributes across 4 EC2 (t2.micro's cuz I'm cheap) to route traffic and those are all currently hitting one server for my MySQL database (also a t2.micro, totalling 6 separate EC2 instances for the whole system).

            I thinking about horizontally scale my database via Source/Replica distribution, and my thought is that I should route all read queries/GET requests (the highest traffic volume I'll get) to the Replicas and all write queries/POST requests to the Source db.

            I know that I'll have to programmatically choose which DB my servers point to based on request method, but I'm unsure of how best to approach that or if I'm better off vertically scaling my DB at that point and investing in a larger EC2 instance.

            Currently I'm connecting to the Source DB using an express server and it's handling everything. I haven't implemented the Source/Replica configuration just yet because I want to get my server-side planned out first.

            Here's the current static connection setup:

            Simultaneous MySQL Database Connection

            I would be hesitant to use any client input to connect to a server, but I understand how this could be something you would need to do in some scenarios. The simplest and quickest way around this issue would be to create a second database connection file. In order to make this dynamic, you can simply require the module based on conditions in your code, so sometimes it will be called and promised at only certain points, after certain conditions. This process could be risky and requires requiring modules in the middle of your code so it isn't ideal but can get the job done. Ex :

            You probably used a number instead of a string in mongoose.connect() method. Check for missing quotation marks or one of them. Also you can check your credentials in mongodb. Below example code from mongoose docs.
