Express is a lightweight and flexible Node.js framework that offers a wide range of features for mobile and web applications. It is easy to create a robust API using a variety of HTTP utility methods and middleware. Express offers a thin layer that covers the core web application features without obscuring the Node.js features you already love. Express does not have any notion of a database. Third-party Node modules allow you to interface with almost any database. Express does not recognize 404 responses as errors and will not capture them. This is because a response of 404 indicates that there is no additional work to be done. Express has executed all middleware functions, routes, and found none of them to be responsive.

You can create powerful, scalable apps with minimal overhead and all the functionality you need. Your code is yours. hapi was originally developed to support Walmart's Black Friday sales. It continues to be a trusted choice for enterprise-grade backend requirements. Every line of code that you receive when you install hapi has been validated. You don't have to worry about a deep dependency being neglected or handed to someone untrustworthy. hapi is the only leading framework that doesn't have any code dependencies. hapi needs the most secure settings to manage and control code. This includes 2FA for all contributors. Every component of hapi comes with the most secure defaults. Along with protecting server load through payload limits and timeouts, the hapi block error messages that could leak information. Node Framework's most comprehensive authorization and authentication API.

Express's new web framework Koa was created by the team behind Express. It aims to be a smaller and more expressive web framework that can be used to build web applications and APIs. Koa leverages async functions to eliminate callbacks and improve error handling. Koa doesn't bundle any middleware in its core. It provides an elegant suite that makes writing servers fast and fun. A Koa application is an object that contains a collection of middleware functions. These functions are composed and executed in a stack-like fashion upon request. Koa is similar in design to Ruby's Rack and Connect. However, Koa provides high-level "sugar", at the low-level middleware layer. This increases interoperability and robustness and makes middleware writing much more enjoyable.

It is not easy to develop RESTful web service that support exposing data in a variety representation media types, and abstract away the low level details of client-server communications without a good toolkit. A standard and portable JAX RS API was designed to simplify the development and deployment of RESTful web service clients and services in Java. Jersey RESTful Web Services 3. x Framework is an open source, production-quality framework that supports Jakarta RESTful Web Services 3.0. Jersey framework is much more than JAX-RS's reference implementation. Jersey's API extends JAXRS with new features. GlassFish will continue to track the JAX-RS API, and release regular releases of production-quality reference implementations. APIs are provided to extend Jersey and build a community. It makes it easy to create RESTful Web Services using Java and the Java Virtual Machine.

Rustless provides a REST API micro-framework. It's designed as a simple DSL for developing RESTful APIs easily on top of Iron web framework. It supports common conventions such as multiple formats, subdomain/prefix restrictions, content negotiation and versioning. Rustless is a Ruby port of the Grape library. Hyper, an HTTP library in Rust. Rustless, like Rust, is still in its early stages of development. Don't be surprised if APIs are changed and things break. File an issue or submit pull requests if something isn't working correctly. Rustless was built on Iron which was built on Hyper which is synchronous. Hyper is currently limited and cannot handle many simultaneous connections. This is especially true with keep-alive. It is highly recommended that you use a lightweight asynchronous webserver such as Nginx to serve as a reverse proxy with Rustless.

Bit is a collaborative and scalable way to create and reuse components. It provides everything you need, from local development to cross-project integrations. It's free to try. Bit is an open-source toolchain that allows for component-driven development. Distribute composable software instead of monolithic apps. Distribute component ownership across development teams. Components are simple to replace and refactor. Develop consistency and standards across products and teams. Instead of reinventing the wheel, combine existing components to create new ones. Create a reusable design system and UI. Develop a consistent and reusable UI system. Code and teams should be distributed. Encourage autonomy and standardization. Scale to cross-team collaboration. This will bridge the gap between product design, development, and design. A composable and scalable backend that doesn't repeat itself is possible.

It is based upon the concept of Model,View and Controllers. The framework is designed with a clean style in mind, which results in code that can be maintained for a long time. Other popular frameworks are designed with the mindset of launching quickly. This leads to code that is easy to deploy, but becomes complex after several iterations. Apache or gunicorn is an example of a control process. When the controller process is started, it receives a manifest. All requests sent to the controller process are routed to the program in the manifest. A manifest is a collection of programs. A user sends a request to a controller process. This can be either a web request or a command-line invocation or any other action handled by a Controller Process.

API development is dramatically simplified by using multiple interfaces. With hug, you can design and develop an API once, and then expose it to your clients in the way they need. Hug is the fastest way to create Python3 APIs, whether you want to do it locally, via HTTP or on the command line. Hug has been designed with performance in the forefront of its mind. It is designed to only consume resources when needed and is compiled with Cython for amazing performance. Huge is one of the fastest Python Frameworks. It is also the fastest high-level Python 3 framework. With hug, you can specify which versions or ranges of versions your API supports. This will then be enforced and communicated automatically to the API's users.

CherryPy lets developers build web applications the same way as they would any other object-oriented Python programme. This allows for smaller source code to be developed in less time. CherryPy has been around for more than ten year and has proven to be reliable and fast. Many sites, from the most basic to the most demanding, use it in production.

Falcon is a minimalist Python web API Framework for building robust microservices and app backends. The framework is compatible with both ASGI and gevent/meinheld. The Falcon web framework promotes REST architecture. Resource classes implement HTTP handlers to resolve requests and perform transitions. Falcon is a complement to more general Python webframeworks by adding extra reliability, flexibility and performance where you need it. You can use a number of Falcon templates, add-ons and complementary packages in your projects. You can find a few of these on the Falcon Wiki as a start, but you might also want to search PyPI for more resources.

Sinatra has a number built-in settings which control the activation of certain features. The settings object is a request context object that contains application-level variables. These variables can be modified by using the set, disable, or enable methods. Applications can set their own custom settings, as well as default built-in framework settings. In its simplest form the set method creates an application attribute by taking a setting value and name. Extensions provide helper methods or class methods to Sinatra applications. These methods are usually listed and described in the extension home pages. Installing a gem, library or a file is all that's needed to use an extension.

A Ruby framework that allows you to create REST-like APIs.

Slim is a great tool for creating APIs that consume data, repurpose it, or publish it. Slim is a great tool to create rapid prototypes. You can even create full-featured web apps with user interfaces. Slim is also super fast and requires very little code. You don't need to use a solution that has everything like Symfony and Laravel. These are excellent tools, no doubt. They are often overkill. Slim offers a minimal set that does exactly what you need. You will need a webserver like Nginx, Apache or similar. Slim apps contain routes that respond to HTTP requests. Each route calls a callback, and returns an HTTP reply. To get started you must first configure and instantiate the Slim application. Next, you define your application routes.
