How to access server context set by middleware

[aheissenberger]

1. How can I add a middleware - e.g. for reading Authentication Layer and add Content to a server context
2. How can I access the server context in a React Server Component

I found the example 08_cookies but I use createPages in entries.tsx and I found no way to add a Middleware without creating a start.js or dev.js and modify the builder for e.g. serve-aws-lambda.ts.

Would it be possible to add this to waku.config.ts?

This is also what I want to cover with #329.
08_cookies will be updated then without needing (dev|start).js.

There's one challenge though. As we want to avoid node dependency, we don't use AsyncLocalStorage. Currently, we use this for server context, but that's not very useful (only accessible from entries.tsx and server actions. And, this is very confusing.) I will look into React.cache for the solution, hopefully possibly.

I did it with React.cache in my #462 pull request

Nice.

@himself65 also wanted to avoid this hack.

We used to have getContext, which is removed in #213.
I will re-implement it with React.cache.
As it's going to be a breaking change, it will be in v0.20.
Please be patient.

With #513 middleware and server context is supported. An implementation is the example examples/08_cookie
