RestSharp
Simple REST and HTTP API Client for .NET
RestSharp is probably the most popular HTTP client library for .NET. Featuring automatic serialization and deserialization, request and response type detection, variety of authentications and other useful features, it is being used by hundreds of thousands of projects. RestSharp passed over 32 million downloads on NuGet, with average daily download count of 10,000. It's being used by many popular OSS projects, including Roslyn and Swagger. The main purpose of RestSharp is to make synchronous and asynchronous calls to remote resources over HTTP. As the name suggests, the main audience of RestSharp are developers who use REST APIs. However, RestSharp can call any API over HTTP (but not HTTP/2), as long as you have the resource URI and request parameters that you want to send comply with W3C HTTP standards. RestSharp can take care of serializing the request body to JSON or XML and deserialize the response. It can also form a valid request URI based on different parameter kinds. -

Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -

Feign
Make writing Java http clients easier
Feign is a Java to HTTP client binder that was built primarily to make writing Java http clients easier. Inspired by previous projects Retrofit, JAXRS-2.0 and WebSocket, Feign was designed to reduce the complexity that is often involved in binding the Denominator uniformly to HTTP APIs, no matter the ReSTfulness. Feign works by processing annotations into a templatized request, to which arguments are applied in a straightforward manner before output. While it may only support text-based APIs, it simplifies system aspects dramatically and makes it much easier to unit test your conversions. Feign makes use of great tools like Jersey and CXF for writing Java clients for ReST or SOAP services. It also lets you write your own code on top of http libraries, and connects your code to http APIs with little overhead. -

TinyGSM
A small Arduino library for GSM modules, that just works
A small Arduino library for GSM modules that just works. This library is easy to integrate with lots of sketches that use Ethernet or WiFi. PubSubClient (MQTT), Blynk, HTTP Client, and File Download examples are provided. Arduino GSM library uses 15868 bytes (49%) of Flash and 1113 bytes (54%) of RAM in a similar scenario. TinyGSM also pulls data gently from the modem (whenever possible), so it can operate on very little RAM. Now, you have more space for your experiments. TCP (HTTP, MQTT, Blynk, ...) All modules support TCP connections. Most modules support multiple simultaneous connections. TCP and SSL connections can usually be mixed up to the total number of possible connections. Many GSM modems, WiFi, and radio modules can be controlled by sending AT commands over Serial. TinyGSM knows which commands to send, and how to handle AT responses, and wraps that into the standard Arduino Client interface. -

Faraday
Simple, but flexible HTTP client library, with support for backends
Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters (such as Net::HTTP) and embraces the concept of Rack middleware when processing the request/response cycle. You probably don't want to use Faraday directly in your project, as it will lack an actual client library to perform requests. Instead, you probably want to have a look at Awesome Faraday for a list of available adapters. The best starting point is the Faraday Website, with its introduction and explanation. This library aims to support and is tested against the currently officially supported Ruby implementations. This means that, even without a major release, we could add or drop support for Ruby versions, following their EOL. Currently that means we support Ruby 2.6+. You can also install the faraday_middleware extension gem to access a collection of useful Faraday middleware. -
22
HTTP Kit
Clojure HTTP server/client library with WebSocket support
http-kit is a minimalist, event-driven, high-performance Clojure HTTP server/client library with WebSocket and asynchronous support. A simple, high-performance event-driven HTTP client+server for Clojure. HTTP Kit is an (almost) drop-in replacement for the standard Ring Jetty adapter. So you can use it with all your current libraries (e.g. Compojure) and middleware. Using an event-driven architecture like Nginx, HTTP-kit is very, very fast. It comfortably handles tens of thousands of requests/sec on even midrange hardware. Here is another test about how it stacks up with others. It's not only fast, but efficient! Each connection costs nothing but a few kB of memory. RAM usage grows O(n) with connections. Written from the ground-up to be lean, the entire client/server is available as a single ~90kB JAR with zero dependencies and ~3k lines of (mostly Java) code. Synchronous is simple. Asynchronous is fast & flexible. -

Retrofit For Dart
Retrofit.dart is an dio client generator using source_gen
retrofit.dart is a type conversion dio client generator using source_gen and inspired by Chopper and Retrofit. If you want to parse models on a separate thread, you can take advantage of the compute function, just like Dio does when converting String data responses into json objects. Avoid using Map values, otherwise, multiple background isolates will be spawned to perform the computation, which is extremely intensive for Dart.
