How sls_debug=* cmd works - node.js

I wanted to know how deploying serverless project in debug mode works?
I generally use sls deploy --satge dev command to deploy my nodejs projects on aws. But somehow it is failing and I read on internet that I can use debug mode to get the logs.
So, now I'm using sls_debug=* sls deploy --satge dev. But I don't know where to see the logs so that I can pin point the failure.

Error running nextjs with PM2 on Azure App Service on Linux

The pipelines and releases seem to work finely as they get the artifact deployed on the app service or so it seems as the output error happens on start of the PM2 process.
I haven't found anything on this error on google, and don't know if there is a way to update PM2 on the app service machine as PM2 itself suggests.
These are the logs.
Error message
summary image
I was expecting the app to work and no longer show an application error as I fixed both build and release pipelines.
This is a picture of the important bit of info of the error as its really long
Check the below steps to run nextjs with PM2.
First create a nextJS app.
Run npm run dev command to run the app in development.
Deploy the app to Azure Linux App Service.
Open the SSH of the Azure App Service to run the PM2 commands.
We can open directly with the below URL.
Path to SSH - https://YourDeployedAppName.scm.azurewebsites.net/
OR
Navigate to the deployed Azure Linux App => Advanced Tools => Go => SSH.
Run the below command to install PM2.
npm install pm2 -g
Thanks #Azure OSS Developer Support for the commands.
In Configuration section => General Settings add the Startup command.
pm2 start site/root/index.js --name mynpmnextapp
Your path may differ for the index.js file.
My app entry point is index.js.For some apps it can be server.js.Change it according to your app.
cannot find module `../build/output/log'
Make sure you are not running the PM2 with the output folder. As mentioned above it has to be the entry point either server.js or index.js based on your code files.
don't know if there is a way to update PM2 on the app service
In the KUDU Console use npm install pm2#latest -g to update the PM2.

TeamCity, NodeJS and API testing

I'm setting up CI/CD which includes TeamCity as build server.
I have set up 3 build steps:
npm install,
node server.js,
node run_tests.js
My server.js file runs a REST API via EXPRESS --> which I realized blocks TeamCity in running step #3...which I now understand why...(because everything is run by the same "window" when TeamCity executes it - because it doesn't not exit again...but keeps listening as expected of an API).
How do I run the API, call it and test/confirm it works, shut it down again and then continue with the next step...?
Solved!
Start the app/API via PM2
Execute tests which uses the API
Stop the app/API via PM2
:-)

Angular CLI app not running when deploying to Linux App Service

I'm trying to deploy an Angular CLI app to Azure App Service on Linux OS, using Azure Dev Ops - but no success. I get Image 1. No error in the server or application logs.
This is what I done so far:
Built the Angular CLI app using DevOps Build and placed the resulted "dist" folder to the "drop" folder. See below (Image 2) the tasks that compose my build. This is working fine and creating the expected files.
Created a release in DevOps, deploying all the dist files in the wwwroot folder in the Azure App Service in Linux. Shown below are both, the wwwroot folder (left) and my local dist folder (right) after I run a ng build --prod.
I have the suspicion that I need to kickstart the angular by feeding some time of command when doing the deployment. I have tried running "ng serve --host 0.0.0.0" but that didn't work.
Check the Azure App Service > Linux section on this page. Essentially, you have to serve the app. You can configure this with a ecoysystem.config.js PM2 file in the root directory, with this inside.
module.exports = {
apps: [
{
script: "npx serve -s"
}
]
};
I also added npx serve -s in the App Service Configuration > General Settings > Startup Command
See also: https://burkeholland.github.io/posts/static-site-azure
I had to give the npx serve -s as the startup command
Then set the Runtime Stack with node framework 10.16 (NODE|10.16). See below
Then everything started working.
If you still want to use App Service - Web App you can just the Windows OS instead of Linux.
Here are the parameters I Used:
Since the output of building angular is a static web app, IIS will serve the site right away.
When using Linux App Service container, you may also select PHP stack containing Apache2 Server. Since, Angular files are static ones (JS, CSS, HTML), so you just need some web server to serve this content.
Example configuration:
If you look at the default 'Deploy Node.js App to Azure App Service' release template, it uses the 'Deploy Azure App Service' task and adds the following commands to the task. this might help you out.
There is a subtle and big difference between the Linux and Windows App service: IIS - which in Windows is actively looking to serve any app, whereas in Linux you have to spin up something on your own to serve it - Express for example.
After some research I discovered that I don't need a full App service dedicated to run a static app (such as Angular or React). It can be done just as efficiently and much cheaper with something like Storage. -> https://code.visualstudio.com/tutorials/static-website/getting-started
I had the same problem on Azure App Service with Linux and Node, solved it using below startup command
pm2 serve /home/site/wwwroot --no-daemon --spa

Deploy ember application in Bluemix

I am trying to deploy an existing ember-nodejs application into bluemix environment. I tried the following steps.
bluemix api https://api.ng.bluemix.net
bluemix login -u username -o org_name -s space_name
cf push app_name
I also tried the above command with an ember build pack from the list of
compatible CF build packs
cf push app_name -b https://github.com/cloudfoundry-community/cf-docs-contrib/wiki/Buildpacks
Uploading is successful, but the application doesnt start up. Is there a recommended way of deploying ember-node js application?
Update
It was a memory issue. I removed the other running apps and tried the cf push command again. The node modules got installed and the application also started without any fuss.
According to the user, this was actually a memory issue. Once he stopped the other running apps, his node modules were installed and the application started without any further errors. There are no issues specific to deploying ember-nodejs applications in the Bluemix environment.

Logging on gcloud node.js

I'm experimenting with node.js and managed servers. So far so good. I just can't figure out how to log to the console on my development server. I'm talking about the console I see in the terminal after running gcloud preview app run . (not the browser console). console.log() doesn't appear to do anything at all.
Try using this command:
gcloud preview app --verbosity debug run .
