Javascript: import version from package.json

Question

Javascript argparse package allows to enable -v, --version option by default:

const parser = new ArgumentParser({
  version: "0.0.1",
  ...

I can comment out the version attribute, and enter something like this:

parser.addArgument(["-V", "--version"], {
  help: "package version",
  action: "version",
  version: "v0.1.0",
});

Almost perfect; I'd like to import the version from package.json , if possible.

Answer 1

You can get the version of the app as follows.

const packageObj = require('./package.json');
const version = packageObj.version;
