Under scripts in package.json I have the following.
'refresh': node refresh db
Is there a way to trigger this particular npm script on a NodeJS app deployed on Heroku.
Yes:
$ heroku run npm run refresh
Per the Heroku Node.js Documentation, you can add pre and post install scripts. In addition, you can add scripts that can be triggered by environment variables.
You can also do this using only the browser; Just log in to manage your app in the heroku dashboard (https://dashboard.heroku.com/apps/[app_name]) and there click on the right side of it:
More > Run console
Then you can run any command:
command line in heroku

I'm trying to deploy a Node.js (Remix) application to an Azure App Service instance. After installing the npm packages, the post-install script must run for the Remix app to eventually work. The post-install script is npx remix setup node.
Unfortunately, the deployment fails because of the following reason:
npm ERR! could not determine executable to run
I get the same error when trying to use other npx commands, as npx prisma generate. I tried npm exec as well instead of npx.
Thank you in advance!
In startup command try using npx serve -s build/
Also, under your app service Settings blade check all the general settings.
Make sure that your web.config was published along with your app.
So I was trying to deploy my react app to an Azure Web App.
I used a Github Action to build and install the App and then ZIP Deploy it to Azure.
The Problem is that once I open up the WebApp Page it shows me an Application Error (react-scripts could not be found).
I found out that once I copy the react-scripts.cmd / ps1 (from local /node_modules/.bin) to the node_modules/.bin folder of the webapp "https://{WEBAPP-NAME}.scm.azurewebsites.net" it works.
Unfortunately I would have to do that after every build.
How can I come up with a solution to this error?
What I already tried:
Update node and npm
Remove package-lock
Thanks in advance

My package.json:
It looks like this issue: npm package.json scripts not being called
Try running npm run-script if you want to execute a script that is not executed by a built-in npm command.
So I found out, that react-scripts is only working in dev environments. But Azure uses a production env. Therefore the github action not only has to install the prod node_modules (npm install) but also the dev modules (npm install --only=dev).

I just installed node.js on my centos 7 server, then install react
it successfully created my new react app, after that, I run:
npm start
and or serve -s build
but none of these run in my browser.
This site can’t be reached
how can I solve this?
If you have sever inside can you try with start debugging of your application
Stop npm, if you're using yarn
Start the project with command above, inside your project home folder
yarn start
Take some time to learn commands below:
I am trying to deploy a Nestjs API (with Auth0 authentication). When I run it in VS Code with npm run start:watch server, everything's fine.
Now the question is: what should I do to deploy it on a webserver? Should I only copy the dist folder (after runnin tsc)? what about node_modules? Should I leave the port to 3000?
As a side note I am trying to deploy it on Azure but I guess the questions holds for any platform.
Many thanks!
Modify your package.json file, and add a postinstall script, this script should be tsc or tsc --sourceMap false if you would like to avoid sourceMaps from being generated.
That would make azure to run tsc after installing all npm packages, remember to change start script also, so its value is 'node dist/index.js'
I have basically modified this app
https://github.com/heroku/node-js-getting-started.git
Now am trying to deploy in Heroku
My Procfile has this line
web:node index.js
And when I run this command locally,there are no probs..
However if I try to open the link in my browser after following all the steps in https://blog.risingstack.com/node-hero-deploy-node-js-heroku-docker/
I get an error
On checking the logs using heroku logs command I am getting 'node command not found'
Anyone knows the prob?
P.S : I tried changing Procfile contents to npm start but that doesnt launch index.js in the browser.
I suspect that you have not set the buildpacks. Buildpacks tells heroku which kind of application is yours.
Use the below command to set the application of type nodejs.
heroku buildpacks:set heroku/nodejs
And make sure that you have a package.json file in the root of the project which is read by heroku to install the project dependencies.
Why don't you try this below in your Procfile.In my case it runs nicely.
web npm install
You just need to add nodejs buildpack on heroku settings app,
after that you will be able to use npm commands.
