Provide a description of the task

❓ Why

• At some point, npm changed its behavior of the npm version command.
• Before, it just upgraded a package version in package.json.
• Now, it also checks if its dependencies are correctly defined.
• Usually, I need to downgrade npm to 8.5.5 to release packages using CKEditor 5 release tools.
• Let's drop the usage of npm version to avoid issues.

💡 What

• The npm version command is executed for each package that will be released.
  • https://github.com/ckeditor/ckeditor5-dev/blob/a3bb64b0120c7c166c1edf04e578ce47e58b0320/packages/ckeditor5-dev-release-tools/lib/tasks/bumpversions.js#L332
• npm version executes set of commands.

   graph LR;
       A[npm preversion] --> B;
       B(bump version) --> C;
       C[npm version] --> D[npm postversion];
  

  Loading
  • preversion, version and postversion can be specified as npm scripts.
  • The bump version task is a default behavior and cannot be modified.
• Let's drop the execution of npm version. Instead, we implement custom flow of running npm scripts for the backward compatibility:
  • Check if preversion exists. If so, execute its script.
  • Update a version in a package.json.
  • Check if version exists. If so, execute its script.
  • Check if postversion exists. If so, execute its script.
• We decided to use npm version and change the flow. First, we need to bump the package version, then, its dependencies.
