caches collides with the Browser API

[steabert]

In one of our projects we use @apollo/client wich itself includes this package. After bundling as ES module, there is a top-level variable caches that seems to collide with the one in the Browser's API.

So, using the optimism's ES module in a browser with type=module doesn't work. Is that the correct behaviour?

I've got the same issue. I'll follow this.

Renaming the variable of cache variable in the bundle.cjs.js and bundle.esm.js solves it for me.

optimism/src/index.ts

Line 111 in 0f17708

const caches = new Set<Cache<any, AnyEntry>>();

Afterwards we make a patch using:

patch-package optimism

Hope this helps.

Revisiting this problem, I think I probably made the mistake of loading an ESM bundle as text/javascript while going back and forth between ESM and IIFE, and didn't notice that. If I load my ESM bundle as module it all works (as it should).
