gRPC Services

[jamesdbrock]

Issue for discussion of gRPC implementation.

Buffer instances are also JavaScript Uint8Array and TypedArray instances.

gRPC uses HTTP/2. https://grpc.io/docs/what-is-grpc/faq/#why-is-grpc-better-than-any-binary-blob-over-http2

There is this in Node.js https://nodejs.org/api/http2.html

But you cannot use HTTP/2 from browser? https://grpc.io/blog/state-of-grpc-web/

You can use gRPC from the browser with an HTTP/2 proxy https://grpc.io/docs/what-is-grpc/faq/#can-i-use-it-in-the-browser

[jamesdbrock]

The Node.js HTTP/2 API exposes Readable and Writable Streams, so to make this simple we could generate code in terms of https://pursuit.purescript.org/packages/purescript-node-streams-aff

gRPC over HTTP2

“gRPC does not currently support/use PUSH_PROMISE.”

@jamesdbrock have you made any progress on this so far? I'm looking for an alternative to PureScript that does not involve grpc Node bindings, but it seems I don't have many options.

[jamesdbrock]

@klarkc Not really, I wrote purescript-node/purescript-node-http#45 , which you have seen. Even with that HTTP/2 implementation, there would be more work to implement gRPC.
