Redux: Passing down Arguments to Actions that could be retrieved from State?

Question

I have a collection of articles. A user sometimes edits or deletes an article. My app keeps track in the state which article is currently being worked on (call this the currentArticleId).

Now when a user edits or deletes an article, would I then give my action-creator the currentArticleId as an argument (e.g.: deleteArticle(this.props.currentArticleId)), or would I NOT do that and just fire the action creator without arguments (e.g.: deleteArticle()), and retrieve the currentArticleId from state in my action creator?

What's best practice here? Why would I choose one solution over the other?

Answer 1

If by state you mean Redux application state, then there is no right or wrong answer. You can even have two actions - deleteCurrentArticle() or deleteArticle(articleId) and use whatever suits you more.

However if you're asking about the component state, I think action creators should be decoupled from components. So I'd prefer passing the currentArticleId as an argument.
