Unify the version numbers in manifest files

npm i -D gulp-unify-versions

This is useful when you want to synchronize the version of the manifest file in conjunction with the npm version command.

For example:

Add the following task to gulpfile.js.

const gulp = require('gulp');

exports['version:unify'] = async function () {
  const unify = require('gulp-unify-versions');
  return gulp.src('./manifest.json')
    .pipe(unify('./package.json'))
    .pipe(gulp.dest('./'));
}

Add a version script to package.json as follows.

    "script": {
+     "version": "gulp version:unify && git add  manifest.json"
    }

When npm version patch is executed, the version of package.json and the version of manifest.json are the same.
