Not able to run nodejs as docker image on Windows using Docker Desktop

I am trying to run nodejs as docker image.

Code Location: https://github.com/Naresh-Chaurasia/Docker-for-Web-Developers/tree/master/Module4-Hooking_Your_Source_Code_into_a_Container/ExpressSite

I checkout the above code, and go to ExpressSite directory, and use the following command:

docker run -p 8080:3000 -v C:/tmp/ExpressSite:/var/www -w "/var/www" node npm start

On executing the above command i get the following error:

> [email protected] start
> node ./bin/www

node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module 'express'
Require stack:
- /var/www/app.js
- /var/www/bin/www
    at Function.Module._resolveFilename (node:internal/modules/cjs/loader:933:15)

  code: 'MODULE_NOT_FOUND',
  requireStack: [ '/var/www/app.js', '/var/www/bin/www' ]
}

I am using Docker Desktop on windows.

I am not much familiar with nodejs and learning dockers from Pluralsight course.

Can some one give pointers how to fix this issue.

Thanks.

You need to install the packages from package.json file into the docker container. You can create a dockerFile or you can run this first docker run -p 8080:3000 -v C:/tmp/ExpressSite:/var/www -w "/var/www" node npm install

I suggest you create a docker file like shown here
