    AIOHTTP

    AIOHTTP

    Asynchronous HTTP client/server framework for asyncio and Python

    Asynchronous HTTP Client/Server for asyncio and Python. AIOHTTP supports both client and server side of HTTP protocol. A long awaited new feature is tracing client request life cycle to figure out when and why client request spends a time waiting for connection establishment, getting server response headers etc. Now it is possible by registering special signal handlers on every request processing stage. The main change is dropping yield from support and using async/await everywhere. Farewell, Python 3.4. You often want to send some sort of data in the URL’s query string. If you were constructing the URL by hand, this data would be given as key/value pairs in the URL after a question mark, e.g. httpbin.org/get?key=val. Requests allows you to provide these arguments as a dict, using the params keyword argument. aiohttp internally performs URL canonicalization before sending request.

    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.

    OpenAPI.NET

    OpenAPI.NET

    Object model for OpenAPI documents in .NET

    The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model. The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme. Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object. Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object.

    Faraday

    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.

    HttpClient component

    HttpClient component

    Provides powerful methods to fetch HTTP resources synchronously

    Provides powerful methods to fetch HTTP resources synchronously or asynchronously. The HttpClient component is a low-level HTTP client with support for both PHP stream wrappers and cURL. It provides utilities to consume APIs and supports synchronous and asynchronous operations. The HTTP client contains many options you might need to take full control of the way the request is performed, including DNS pre-resolution, SSL parameters, public key pinning, etc. They can be defined globally in the configuration (to apply it to all requests) and to each request (which overrides any global configuration). It's common that some of the HTTP client options depend on the URL of the request (e.g. you must set some headers when making requests to GitHub API but not for other hosts). If that's your case, the component provides scoped clients (using ScopingHttpClient) to autoconfigure the HTTP client based on the requested URL.

    pgrok

    pgrok

    HTTP/TCP reverse tunnel solution through SSH remote port forwarding

    The pgrok is a multi-tenant HTTP/TCP reverse tunnel solution through remote port forwarding from the SSH protocol. This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider. It gives a stable subdomain for every user and gated by your SSO through the OIDC protocol. Think of this as a bare-bones alternative to the ngrok's $65/user/month enterprise tier. Trying to put this behind a production system will blow up your SLA. For individuals and production systems, just buy ngrok, it is still my favorite.

    sish

    sish

    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.

    undici

    undici

    An HTTP/1.1 client, written from scratch for Node.js

    An HTTP/1.1 client, written from scratch for Node.js. This section documents our most commonly used API methods. Additional APIs are documented in their own files within the docs folder and are accessible via the navigation list on the left side of the docs site. Garbage collection in Node is less aggressive and deterministic (due to the lack of clear idle periods that browsers have through the rendering refresh rate) which means that leaving the release of connection resources to the garbage collector can lead to excessive connection usage, reduced performance (due to less connection re-use), and even stalls or deadlocks when running out of connections.

    The flexible HTTP client library for Elixir

    The flexible HTTP client library for Elixir, with support for middleware and multiple adapters. Tesla is an HTTP client loosely based on Faraday. It embraces the concept of middleware when processing the request/response cycle. Define module with use Tesla and choose from a variety of middleware. Tesla is built around the concept of composable middlewares. This is very similar to how Plug Router works. All HTTP functions, such as Tesla.get/3 and Tesla.post/4, can take a dynamic client as the first argument. This allows using convenient syntax for modifying the behavior in runtime. Tesla supports multiple HTTP adapter that do the actual HTTP request processing. Each piece of the stream will be encoded as JSON and sent as a new line (conforming to JSON stream format). You can set the adapter to Tesla.Mock in tests.
