grpc vs rest: What are the differences?

# Introduction

The key differences between gRPC and REST are outlined below:

1. **Communication Protocol**: gRPC uses the HTTP/2 protocol while REST typically uses the HTTP/1.1 protocol. HTTP/2 in gRPC allows for multiplexing, request-response multiplexing, and server push, enhancing efficiency and performance compared to REST.
   
2. **Message Format**: gRPC uses Protocol Buffers (protobuf) as the default message format for serialization while REST uses JSON or XML. Protocol Buffers are binary and more compact than JSON or XML, resulting in faster transmission and reduced bandwidth consumption.
   
3. **Service Definition**: gRPC uses Protocol Buffers to define services and messages in a .proto file, which are then compiled to generate client and server code, ensuring a strict contract between components. In contrast, REST relies on URI, methods, and payloads to define services without a formal contract.
   
4. **API Style**: gRPC is designed around the concept of Remote Procedure Calls (RPC), where a client can directly call a function on a server, while REST follows the principles of Representational State Transfer, treating server resources as stateless entities accessible through URLs.
   
5. **Error Handling**: gRPC uses status codes defined in the protocol buffer to handle errors systematically, making it easier to distinguish between different types of errors. In REST, error handling is typically done through HTTP status codes, which may not always provide detailed information on the error.
   
6. **Client Libraries**: gRPC provides official client libraries in multiple languages, allowing seamless integration with various platforms and frameworks. REST, on the other hand, relies on HTTP client libraries that may vary in features and functionalities across different programming languages.

In Summary, the key differences between gRPC and REST lie in the communication protocol, message format, service definition, API style, error handling, and client libraries.

What are some alternatives to grpc, rest?

rake

Rake is a Make-like program implemented in Ruby. Tasks and dependencies are specified in standard Ruby syntax. Rake has the following features: * Rakefiles (rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?) * Users can specify tasks with prerequisites. * Rake supports rule patterns to synthesize implicit tasks. * Flexible FileLists that act like arrays but know about manipulating file names and paths. * Supports parallel execution of tasks.

pry

An IRB alternative and runtime developer console.

rspec

BDD for Ruby.

rails

Ruby on Rails is a full-stack web framework optimized for programmer happiness and sustainable productivity. It encourages beautiful code by favoring convention over configuration.

simplecov

Code coverage for Ruby 1.9+ with a powerful configuration library and automatic merging of coverage across test suites.

puma

Puma is a simple, fast, threaded, and highly concurrent HTTP 1.1 server for Ruby/Rack applications. Puma is intended for use in both development and production environments. It's great for highly concurrent Ruby implementations such as Rubinius and JRuby as well as as providing process worker support to support CRuby well.

pg

Pg is the Ruby interface to the {PostgreSQL RDBMS}[http://www.postgresql.org/]. It works with {PostgreSQL 9.2 and later}[http://www.postgresql.org/support/versioning/]. A small example usage: #!/usr/bin/env ruby require 'pg' # Output a table of current connections to the DB conn = PG.connect( dbname: 'sales' ) conn.exec( "SELECT * FROM pg_stat_activity" ) do |result| puts " PID | User | Query" result.each do |row| puts " %7d | %-16s | %s " % row.values_at('procpid', 'usename', 'current_query') end end.

rspec-rails

Rspec-rails is a testing framework for Rails 3+.

rubocop

Automatic Ruby code style checking tool. Aims to enforce the community-driven Ruby Style Guide.

byebug

Byebug is a Ruby debugger. It's implemented using the TracePoint C API for execution control and the Debug Inspector C API for call stack navigation. The core component provides support that front-ends can build on. It provides breakpoint handling and bindings for stack frames among other things and it comes with an easy to use command line interface.
