apollo-angular VS Protobuf

Case in point: Apollo Angular (GraphQL) does the basics of what you want, but it does so much more that its existence is justified...yet you still have to use RxJS with it.

Not that I know of. But here are a few things that may be of interest.

Redwood's GraphQL API is built on Yoga (we collaborate tightly with The Guild) — https://www.graphql-yoga.com You just need a GraphQL Client, which The Guild already has an option ready for you https://apollo-angular.com (Note: Apollo or other clients fine as well.)

Here's an example "How To" about connecting Next (React) with Redwood: https://community.redwoodjs.com/t/how-to-connect-a-next-js-f...

I'm a co-founder of Redwood and help lead the project so I can say as a matter of fact we a highly collaborative and enjoy (and support) exploratory projects. It's a priority for us to better demonstrate the power of Redwood's API through examples. If you'd be interested in digging in collaboratively with the community, I can help connect the dots. Just kick things off over here and tag me @thedavidprice: https://community.redwoodjs.com

No pressure at all! Just wanted you to know the invitation is open. Anytime.

Apollo Angular

TLDR: We’ve built a multiplayer shooter and used Apollo’s GraphQL subscriptions to keep game state in sync at a very high frequency. Here’s our impressions! Tools used: Angular-cesium, Apollo Angular, CesiumJS, Angular Go Play: geo-strike.com

For at least 4 years protobuf has had decent support for self-describing messages (very similar to avro) as well as reflection

https://github.com/protocolbuffers/protobuf/blob/main/src/go...

Xgooglers trying to make do on the cheap will just create a Union of all their messages and include the message def in a self-describing message pattern. Super-sensitive network I/O can elide the message def (empty buffer) and any for RecordIO clone well file compression takes care of the definition.

Definitely useful to be able to dig out old defs but protobuf maintainers have surprisingly added useful features so you don’t have to.

Bonus points tho for extracting the protobuf defs that e.g. Apple bakes into their binaries.

gRPC Gateway is a protoc plugin that reads gRPC service definitions and generates a reverse proxy server that translates a RESTful JSON API into gRPC.

To use more recent versions of protoc in future applications, you can download them from the Protobuf repository.

Use the Protobuf CLI protoc and the plugin protoc-gen-tonic.

> didn’t find any standard for separating protobuf messages

The fact that protobufs are not self-delimiting is an endless source of frustration, but I know of 2 standards:

- SerializeDelimited* is part of the protobuf library: https://github.com/protocolbuffers/protobuf/blob/main/src/go...

- Riegeli is "a file format for storing a sequence of string records, typically serialized protocol buffers. It supports dense compression, fast decoding, seeking, detection and optional skipping of data corruption, filtering of proto message fields for even faster decoding, and parallel encoding": https://github.com/google/riegeli

It looks like it is in fact universal. Just glancing at the code here, it looks like the tool searches any arbitrary file for bytes that look like encoded protobuf descriptors, specifically looking for bytes that are plausibly the beginning of a FileDescriptorProto message defined here:

https://github.com/protocolbuffers/protobuf/blob/main/src/go...

This takes advantage of the fact that such descriptors are commonly compiled into programs that use protobuf. The descriptors are usually embedded as constant byte arrays. That said, not all protobuf implementations embed the descriptors and those that do often have an option to inhibit such embedding (at the expense of losing some dynamic introspection features).

Not much. You can check the source code in https://github.com/protocolbuffers/protobuf. For example, for serializing a boolean in C#: https://github.com/protocolbuffers/protobuf/blob/main/csharp/src/Google.Protobuf/WritingPrimitives.cs#L165. Strings and objects are a bit more complicated, but it is all about turning the data into its byte representation.

One of the key feature of gRPC is protobuf .proto file(nothing but just a contract for me between two communicator code components) This file and protobuff compiler is so mature, then it generates a direct client implementation using protoccompiler. ref
