I have an app running on Nest.Js / Node.Js which does text processing and because of that it has an
.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:...

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.
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?...

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

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:
lib/src/index.cjsCommonJS entry point (for PM2).
lib/src/index.jsESModule entry point (for ESM-compatible tools).

- When I run:

So, how can I use pm2 commands on Heroku, e.g. l:

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:

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:

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

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)?
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!

I ended up spinning up a proxy lambda as my API gateway (middle man) between my client and server. I also have the proxy denying any requests not coming from my website.
