Angular / node.js how to copy the app version from package.json to anothe non json file

Question

Within my Angular app, and while building it, i ve to catch the app version, which is inside my package.json file and copy it to another file which would be not a json file.

My package.json file:

{
  "name": "my app",
  "author": "ME",
  "version": "0.1.3",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --public-host --port 4222 http://localhost:4222/",
    "build": "ng build",
    "sync-version": "sync-json -v --property version --source package.json projects/cockpit-tools/package.json && sync-json -v --property version --source package.json projects/cockpit-tools-demo/src/assets/configuration/properties.json",
    "sync-custom": "shx  node -p -e \"require('./package.json').version\"",
    "copy-version":"MY_COMMAND"
...
}

My target file is properties file whih looks like this, and which is located in same path of package.json (this file is used in another level of automation, that's why i can't change it)

app-infos.properties

project.version=0.0.0
project.author=ME

My purpose is to write a command line task script which i may run to synchronize / copy the version from package.json to the project.version property inside my target file.

I ve tried an npm library called sync-version , but that works only when the target is a json file

I ve tried also to do it with shell command line within the shx package. also that didn't work as expected.

i ve also tried some node.js tricks (require...) but the problem persists

i need to find a way to do it with the simpliest way and not be obliged to install some linux tools or similar(jq or other), since this would run in some CI CD contexts, so that would rather to be as native and as generic as possible.

Suggestions?

A classic DevOps situation:)

CI/CD usually happens on linux envs. You will probably have plain shell/bash. Try extractinf the version to a variable:

myVersion=`grep 'version:' package.json | awk '{print $2}'`

then replacing it in the apps-info:

sed -i "s/0.0.0/$myVersion/" apps-info.properties

We can make ot more generic by always pulling the last version instead of 0.0.0, but i think you should have a place holder like 0.0.0
