Svelte REPL broken on svelte.dev

[benmccann]

codemirror.css is not being included. It looks like Repl.js dynamically imports codemirror.js which imports codemirror.css. In 0.28.0 it got stuck into main.css

The trigger for the problem is that the index route imports the REPL and the repl route dynamically imports the REPL. As a result, codemirror.js has already been added to processed_chunks and isn't seen as a leftover chunk from a dynamic import.

It seems the original algorithm of just sticking the leftover stuff in the application entry chunk isn't going to work. We could probably solve it by making the existing algorithm even more complicated:

• Find all dynamically imported chunks that are not routes
• Calculate the transitive dependency tree of each dynamically imported route
• Include the css for each of these trees in the application entry chunk

The reason this had not been reported in previous versions of Sapper is because Sapper duplicated all CSS into main.css (#1076 #1127)
