## Beyond REST
chi is just a http router that lets you decompose request handling into many smaller layers.
Many companies including Pressly.com (of course) use chi to write REST services for their public
APIs. But, REST is just a convention for managing state via HTTP, and there's a lot of other pieces
required to write a complete client-server system or network of microservices.
Many companies use chi to write REST services for their public APIs. But, REST is just a convention
for managing state via HTTP, and there's a lot of other pieces required to write a complete client-server
system or network of microservices.
Looking ahead beyond REST, I also recommend some newer works in the field coming from
[gRPC](https://github.com/grpc/grpc-go), [NATS](https://nats.io), [go-kit](https://github.com/go-kit/kit)
and even [graphql](https://github.com/graphql-go/graphql). They're all pretty cool with their
own unique approaches and benefits. Specifically, I'd look at gRPC since it makes client-server
communication feel like a single program on a single computer, no need to hand-write a client library
and the request/response payloads are typed contracts. NATS is pretty amazing too as a super
fast and lightweight pub-sub transport that can speak protobufs, with nice service discovery -
an excellent combination with gRPC.
Looking beyond REST, I also recommend some newer works in the field:
* [webrpc](https://github.com/webrpc/webrpc) - Web-focused RPC client+server framework with code-gen
* [gRPC](https://github.com/grpc/grpc-go) - Google's RPC framework via protobufs
* [graphql](https://github.com/99designs/gqlgen) - Declarative query language
* [NATS](https://nats.io) - lightweight pub-sub

// HTTP 1.1 "deflate" (RFC 2616) stands for DEFLATE data (RFC 1951)
// wrapped with zlib (RFC 1950). The zlib wrapper uses Adler-32
// checksum compared to CRC-32 used in "gzip" and thus is faster.

// But.. some old browsers (MSIE, Safari 5.1) incorrectly expect

// both ways, first looking for zlib headers.

### mkmerge.go
This program is used to extract duplicate const, func, and type declarations
from the generated architecture-specific files listed below, and merge these
into a common file for each OS.
The merge is performed in the following steps:
1. Construct the set of common code that is idential in all architecture-specific files.
2. Write this common code to the merged file.
3. Remove the common code from all architecture-specific files.
