    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.

    Laravel Webhook Server

    Laravel Webhook Server

    Send webhooks from Laravel apps

    A webhook is a mechanism where an application can notify another application that something has happened. Technically, the application sends an HTTP request to that other application. In this blog post, I'd like to introduce you to two packages that we recently released. The first is laravel-webhook-server, which allows you to send webhook requests. The second one is laravel-webhook-client, which makes it easy to receive those webhook request. Webhooks are very useful when a system wants to be notified as soon as something happens in another system. Let's make that a bit less abstract and take a look at a real-world example. laravel-webhook-server allows you to configure and send webhooks in a Laravel app easily. So you'll install this into the app that wants to notify other apps that something has happened. The package has support for signing calls, retrying calls, and backoff strategies.

    cpprestsdk

    Microsoft project for cloud-based client-server communication

    The C++ REST SDK is a Microsoft project for cloud-based client-server communication in native code using a modern asynchronous C++ API design. This project aims to help C++ developers connect to and interact with services. cpprestsdk is in maintenance mode and we do not recommend its use in new projects. We will continue to fix critical bugs and address security issues. Once you have the library, look at our tutorial to use the http_client. It walks through how to setup a project to use the C++ Rest SDK and make a basic Http request. HTTP client/server, JSON, URI, asynchronous streams, WebSockets client, oAuth. A powerful model for composing asynchronous operations based on C++ 11 features. Windows desktop, Windows Store (UWP), Linux, OS X, Unix, iOS, and Android. Support for Visual Studio 2015 and 2017 with debugger visualizers.

    Milkman

    Milkman

    An extensible request/response workbench

    Milkman is heavily inspired by Postman. But I got sick of all those electron-based applications that need ages and loads of memory to start up. Therefore, this is a JavaFx-based workbench for crafting requests/responses. It is not limited to e.g. HTTP (or more specifically rest) requests. Due to nearly everything being a plugin, other things are possible, like database requests or GRPC, GraphQl, etc. Request-types (e.g. Http Request), request-aspects (e.g. Headers, Body, etc), editors for request aspects (e.g. table-based editors for headers), importers, whatever it is, you can extend it. The core application only handles Workspaces with Environments, Collections, Requests, and their aspects. Several plugins are provided already that extend the core application to be a replacement for postman. Crafting and Executing Http/Rest requests with json highlighting. Support Proxy-server configuration and SSE.

It uses Cron syntax to schedule the checks and comes along with a Web UI and a RESTful JSON API. Create an open-source web application for checking URL statuses with a UI and a REST API which is easy to install and maintain (no external dependencies like Databases, Caches, etc.) in public and private environments.

    Typhon

    Typhon

    A wrapper around Go's net/http to provide safety and convenience

    Typhon is a wrapper around Go's net/http library that we use at Monzo to build RPC servers and clients in our microservices platform. A wrapper around Go's net/http to provide safety and convenience. At Monzo, Typhon forms the basis of most clients and servers in our microservices platform. Forgetting to body.Close() in a client when the body has been dealt with is a common source of resource leaks in Go programs in our experience. Typhon ensures that – unless you're doing something really weird with the body – it will be closed automatically. Marshalling and unmarshalling request bodies to structs is such a common operation that our Request and Response objects support them directly. If the operations fail, the errors are propagated automatically since that's nearly always what a server will want.

    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.

    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.

    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.
