I have created docker image for the node application, which is working fine when i run before creating docker image.
my docker file contains:
FROM node:7
WORKDIR /app
COPY package.json /app
RUN npm install
COPY . /app
CMD node app.js
EXPOSE 3000
Step 1:
$ docker build -t myapp .
Step 2:
$ docker run -p 3000:3000 myapp
when i run the above command Im facing below error:
$ docker run -p 3000:3000 kpnv7
module.js:472
throw err;

I'm using Backpack to build my node app. When running the app locally, the app itself and the build artefacts are doing okay. But when I move the build results to a Docker image and try to run it, I get the following errors:
Error: Cannot find module 'source-map-support/register'

My Dockerfile:
FROM node:12.21-alpine
ENV NODE_ENV=production
RUN mkdir -p /home/app
COPY ./build /home/app
WORKDIR /home
CMD ["node", "./app/main.js"]
What am I missing? Are there other alternatives for Backpack? Basically, I want to build my app first, move the artefacts into a Docker image and then run that. I'm not looking to build inside an image.
You are missing node_modules.
You have to copy node_modules to container COPY ./node_modules /home/app/node_modules
Or install it during the docker build (remember to copy package.json and package-lock.json) RUN npm ci.
If it is a local development env, you can choose the first option. But if not, a better way is second one.
I'm setting up my dev environment on a fresh system. In my project folder:
npm install
npm run serve
And got this:
Module build failed (from ./node_modules/babel-loader/lib/index.js):

# multi (webpack)-dev-server/client?http://192.168.0.105:8080/sockjs-node (webpack)/hot/dev-server.js ./src/main.js
I checked in node_modules/#babel/compat-data/ and the module is there. Why doesn't webpack (is it webpack?) see it?
Note that I did the same thing on another system a few weeks ago and it worked fine.
I also have a vuepress project on the same new system and it also runs fine.
Thanks
In project folder:
rm package_lock.json
rm -r node_modules
npm install
Turns out I had package_lock.json on git from another system. Removed it and it worked.
you can remove the lock files generated (package-lock.json)
and then remove the node modules from your project.
And then again try to download the dependencies via npm
as npm install
I followed a tutorial to create a CRUD App with Nodejs, I finished the project and everything worked fine. After I tried to move all the files and folders to a new folderand I destroyed everything.
Now when I try to run node app.js the following happen:

throw err;

Any suggestion?
You probably have to make a clean install your dependencies again with npm install, as you might have broken some symlinks (just assuming as I'm not a Windows user).
You can manually delete your node_modules folder and run npm install, or if you have an existing package-lock.json, use npm ci to install exactly the same versions of deps you had before.
Find Visual Studio Code application where I tried to run the file. Things look fine but it says cannot find module. Find my terminal output below along with screenshot in "Node Program"

You have to run npm i and then restart your application and vs code.
