            How to avoid a Nest.Js / Node.Js process taking up 100% of the CPU?
            Asked 2022-Mar-23 at 16:56

            I have an app running on Nest.Js / Node.Js which does text processing and because of that it has an .map (or .forEach) iteration that takes a lot of resources (tokenizing a sentence, then removing the stopwords, etc — for each sentence of which there may be tens of thousands).

            For reproducibility, I provide the code I use below, without the text processing details — just a long heavy loop to emulate my problem:



            Answered 2022-Mar-17 at 15:47

            In terms of limiting a single thread from using 100% CPU, there are architectural ways of doing so at a server level, however I don't think that's really the outcome you would want. A CPU using 100% isn't an issue (CPUs will often spike to 100% CPU for very short periods of time to process things as quickly as possible), it's more of it using 100% CPU for an extended period of time and preventing other applications from getting CPU cycles.

            From what I am seeing in the example code, it might be a better solution to use Queues within NestJS. Documentation can be seen here using Bull. This way you can utilize the rate limits of jobs being processed and tweak it there, and other applications will not be waiting for the completion of the entire process.

            For instance if you have 100,000 files to process, you may want to create a job that will process 1,000 of them at a time and create 100 jobs to be thrown into the queue. This is a fairly typical process for processes that require a large amount of compute time.

            I know this isn't the exactly the answer I am sure you were looking for, but hopefully it will help and provide a solution that is not specific to your architecture.



            Azure Linux App Service : Installing packages after deploy from Devops pipeline
            Asked 2022-Jan-26 at 16:26

            I'm currently setuping a CI/CD pipeline in Azure Devops to deploy a NodeJS app on a linux hosted app service (not a VM).

            My build and deploy both go smoothly, BUT I need to make sure some packages are installed in the environment after the app has been deployed.

            The issue is: whatever apt-get script I create after the deploy, I have to run then manually for them to actually take effect. In the Pipeline log they seem to have been executed, though.

            Here is the part of my yaml code responsible for the deploy, did I miss something?



            Answered 2022-Jan-26 at 16:26

            For now, went with a "" file which I run manually after each deploy. Gonna go through docker later though



            Split text columns into two columns in Pandas DataFrame, for different dataframes
            Asked 2022-Jan-26 at 14:40

            I have six different dataframes, some of this dataframes have 'NaN' values. I tried it without the if statements and it only worked on the dataframe that doesn't have 'NaN' values (I get this error: "ValueError: Columns must be same length as key" when I try it on the other dfs). What I'm trying to do is to create a function to split the df columns into two (air quality values and the unit).

            run pm2 with ES modules
            Asked 2022-Jan-19 at 08:20

            How can i use pm2 in combination with a package based on ES Module (type:"module") I looked into similar Questions without any useful help (some say it does not work on windows, but i am using linux)

            I always receive the error:



            Answered 2022-Jan-19 at 08:20

            To achieve this you can create an intermediary CommonJS module which loads your application from ESModule. It's possible with import function available in commonJs modules.

            This is how might this look:

            • ecosystem.config.js
            • lib/src/index.cjs CommonJS entry point (for PM2).
            • lib/src/index.js ESModule entry point (for ESM-compatible tools).
            • lib/src/app.js Application code.




            Where actually is the syntax error in my github actions yml file
            Asked 2022-Jan-18 at 12:05

            I am actually implementing CI/CD for my application. I want to start the application automatically using pm2. So I am getting the syntax error on line 22.

            This is my yml file

            This is the error I am getting on github



            Answered 2022-Jan-18 at 12:05

            The problem in the syntax here is related to how you used the - symbol.

            With Github actions, you need at least a run or uses field inform for each step inside your job, at the same level of the name field (which is not mandarory), otherwise the github interpreter will return an error.

            Here, from line 22, you used something like this:



            How do PM2 commands on Heroku?
            Asked 2021-Dec-19 at 12:42

            I'm trying to use pm2 on Heroku.

            • When I run: heroku run bash and do a pm2 ls I get an empty list.
            • When I run: heroku ps:exec I get "There was an error connecting to the dyno!"

            So, how can I use pm2 commands on Heroku, e.g. l: pm2 reload all, pm2 list and so on?

            Setting redirect when accessing Cognito via sk-auth
            Asked 2021-Nov-29 at 23:04

            I have built a Svelte application using SvelteKit that uses Cognito for authentication. I used the following site: Cognito authentication for your SvelteKit app guide me in setting this up. The app and connection to Cognito works well when running in local development via npm run dev, however, when running in production on an EC2 server via npm run build and pm2 start /build/index.js it sets the redirect_uri portion of the Cognito URI to http://localhost:3000. I can't figure out how to get it to set the redirect to my actual domain.

            Here are some relevant code snippets on how it is currently set up on EC2:




            Answered 2021-Nov-29 at 22:45

            From what I can tell looking at the sk-auth module source code, redirect_uri doesn't appear to be a valid config option. Try setting the host config option in the global SkAuth constructor instead:



            Node Error: Cannot use import statement outside a module even though I'm not
            Asked 2021-Nov-19 at 00:45

            I am using Pm2 and this is the error:



            Answered 2021-Nov-19 at 00:45

            If the require calls are not throwing an error, the "actual .js file" creating the http server in the post is being treated as CommonJS. But CommonJS code can't use import statements and needs to use import expressions instead (see node and MDN docs).

            If you use dynamic imports ( which are asynchronous) you would also need to use the imported module after an await statement (inside an async function), or in a success handler provided in a then method:



            how to start node js project in a EC2 AWS instance
            Asked 2021-Nov-09 at 06:13

            I am completely new to node js , I am trying to set it up in EC2 AWS.I tried using the command "npm start" but nothing has happened

            below is my package.json



            Answered 2021-Nov-08 at 20:25

            If your site is running properly in your machine, and if you have node/npm installed in your EC2 instance and you are not receiving any errors, looks like your project is running without issues.

            So the problem can be that you are not connect to your site using HTTP.

            Take a look on the security group attached with your instance to check if you allow users to connect on HTTP (80) or HTTPS (443).

            To more information of how to make these ports available for your users check How do I allow my users to connect on HTTP (80) or HTTPS (443)?



            How to run proxy for react/redux application on AWS Amplify
            Asked 2021-Nov-01 at 00:50

            I have recently Implemented Proxy (in Express.js) for my React App to hide API URL's when making a request. It has been working perfectly fine when I run it the proxy and app on localhost. Now that I'm ready to deploy My application to AWS Amplify, I am a little confused as to how I get my proxy to run there since I'm not manually starting the app and proxy from the CLI. Do I need to use an EC2 instance instead or can I achieve this using Amplify?

            Any Help would be greatly appreciated!
