new InMemoryCache throws an error

See original GitHub issue

Trying to create a new InMemoryCache throws an error. I am trying this in React Native, not web.

Intended outcome:

A new InMemoryCache

Actual outcome:

Facing the same issue. TypeError: optimism.dep is not a function. (In 'optimism.dep()', 'optimism.dep' is undefined)

I am migrating from react-apollo to @apollo/client, have tried a lot of things but was unable to fix this issue.

Fixed it.

Apparently the issue was something in the shadow-cljs compilation cache. I fixed it by changing the compiler options flag (https://shadow-cljs.github.io/docs/UsersGuide.html#_output_language_options) but reverting no options to update this issue did nothing (no crash, everything working fine)

Guessing, but most likely an older version of optimism was hanging around in the shadow-cljs compilation cache after upgrading apollo and dependencies.

Sorry for the noise.
