ReferenceError: btoa is not defined (during SSR)
See original GitHub issueWhat:
Performing SSR with atomic-layout results into the following exception:
ReferenceError: btoa is not defined

at app.get (webpack:///./src/server/middleware/ssr/index.js?:42:96)
Why:
I believe btoa is a window method, and is not available on the client-side.
Environment:
- atomic-layout version:
0.6.0
Expected behavior:
Atomic layout doesn’t result into errors during SSR of an application.
Suggestions
Replace btoa with a lightweight hash generator package (or write your own in the sources)

@kettanaito But for SSR in code still
return !('Proxy' in window).Thanks for double checking, @lokhmakov. I already have the fix on my branch. Let me write a test and merge.
I would prefer to use a local util rather than mutating a global variable:
https://github.com/kettanaito/atomic-layout/blob/20ae2182123620b312be0ef5ce677502a698e188/src/utils/strings/btoa.ts#L1-L7
The
windowerror is related to the safety check whether theProxyis defined.
