    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.

    RestSharp

    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.

    distribyted

    distribyted

    Torrent client with HTTP, fuse, and WebDAV interfaces

    Distribyted is an alternative torrent client. It can expose torrent files as a standard FUSE mount or webDAV endpoint and download them on demand, allowing random reads using a fixed amount of disk space. Distribyted supports several ways to expose the files to the user or external applications. Applications that supports WebDAV can access torrent files using this protocol. It is recommended when distribyted is running in a remote machine or using docker. Distribyted can show some kind of files directly as folders, making it possible for applications to read only the parts that they need. Here is a list of supported, to-be-supported, and not supported formats. Play multimedia files on your favorite video or audio player. These files will be downloaded on demand and only the needed parts.

    AWS IoT Device SDK for Embedded C

    AWS IoT Device SDK for Embedded C

    SDK for connecting to AWS IoT from a device using embedded C

    The AWS IoT Device SDK for Embedded C (C-SDK) is a collection of C source files under the MIT open source license that can be used in embedded applications to securely connect IoT devices to AWS IoT Core. It contains MQTT client, HTTP client, JSON Parser, AWS IoT Device Shadow, AWS IoT Jobs, and AWS IoT Device Defender libraries. This SDK is distributed in source form and can be built into customer firmware along with application code, other libraries, and an operating system (OS) of your choice. These libraries are only dependent on standard C libraries, so they can be ported to various OS's - from embedded Real-Time Operating Systems (RTOS) to Linux/Mac/Windows. You can find sample usage of C-SDK libraries on POSIX systems using OpenSSL (e.g. Linux demos in this repository), and on FreeRTOS using mbedTLS (e.g. FreeRTOS demos in the FreeRTOS repository). The coreHTTP library provides the ability to establish an HTTP connection with a server over a customer-implemented transport layer.

    Promxy

    Promxy

    An aggregating proxy to enable HA prometheus

    Promxy is a prometheus proxy that makes many shards of prometheus appear as a single API endpoint to the user. This significantly simplifies operations and use of prometheus at scale (when you have more than one prometheus host). Promxy delivers this unified access endpoint without requiring any sidecars, custom-builds, or other changes to your prometheus infrastructure. Prometheus itself provides no real HA/clustering support. As such the best-practice is to run multiple (e.g N) hosts with the same config. Similarly prometheus has no real built-in query federation, which means that you end up with N sources in grafana which is (1) confusing to grafana users and (2) has no support for aggregation across the sources. Promxy enables an HA prometheus setup by "merging" the data from the duplicate hosts (so if there is a gap in one, promxy will fill with the other). In addition Promxy provides a single datasource for all promql queries.

    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.

    HTTP(S)/WS(S)/TCP Tunnels to localhost using only SSH

    An open source serveo/ngrok alternative. Builds are made automatically for each commit to the repo and are pushed to Dockerhub. Builds are tagged using a commit sha, branch name, tag, latest if released on main. Each release builds separate sish binaries that can be downloaded from here for various OS/archs. Feel free to either use the automated binaries or to build your own. If you submit a PR, images are not built by default and will require a retag from a maintainer to be built. You can also use Docker Compose to setup your sish instance. This includes taking care of SSL via Let's Encrypt for you. This uses the adferrand/dnsrobocert container to handle issuing wildcard certifications over DNS. SSH can normally forward local and remote ports. This service implements an SSH server that only handles forwarding and nothing else. The service supports multiplexing connections over HTTP/HTTPS with WebSocket support.
