Local copy of theme with updated plugins?

[hrishikesh-k]

Hello.

I started playing around with 'Gatsby Starter Chronoblog' since yesterday. Today, I noticed that this theme is using outdated versions of various dependencies. While, it's understandable that the developer can't keep updating this repository everytime a dependency is updated, but, since I would be working on it daily for at least a few weeks now, maybe, I can keep a local copy of the theme up-to-date on dependencies.

So, my question is, how do I do it? It won't make sense to update the package.json in the theme folder from node_modules of my project. Even if I manually add the dependencies in the package.json of my project, how can I make sure the theme would use the latest versions and not download the ones mentioned in its package.json every time I run npm install in terminal?
