KrakenD
High-performance, stateless, declarative, API Gateway written in Go.
KrakenD is more than a typical proxy that forwards clients to backend services, but a powerful engine that can transform, aggregate or remove data from your own or third party services. KrakenD also implements the Backend for Frontend and Micro-frontends patterns to eliminate the necessity of dealing with multiple REST services, isolating clients from the micro-service implementation details. KrakenD's stateless architecture and performance-first approach for every internal component beat any API Gateway in the market. Our customers with massive usage face the networking limits while KrakenD still keeps a low consumption of resources. But don't take our word for granted, do your own benchmarks. All KrakenD endpoint configuration is stored in a plain text .json configuration file. You can edit this file by hand or design your API interface visually using the KrakenDesigner. -

Nodejs Expressjs MongoDB API Project
A boilerplate for REST API Development with Node.js, Express, etc.
A ready-to-use boilerplate for REST API Development with Node.js, Express, and MongoDB. This is a basic API skeleton written in JavaScript ES2015. Very useful to building RESTful web APIs for your front-end platforms like Android, iOS or JavaScript frameworks (Angular, Reactjs, etc). This project will run on NodeJs using MongoDB as a database. I tried to maintain the code structure easily as any beginner can also adopt the flow and start building an API. The project is open for suggestions, Bug reports and pull requests. Basic Authentication (Register/Login with hashed password). Account confirmation with 4 (Changeable) digit OTP. Email helper ready just import and use. JWT Tokens, make requests with a token after login with Authorization header with value Bearer yourToken where yourToken will be returned in Login response. Pre-defined response structures with proper status codes. Included CORS. Book example with CRUD operations. Validations added. -

Ocelot
.NET core API Gateway
Ocelot is a .NET API Gateway. This project is aimed at people using .NET running a micro services / service-oriented architecture that need a unified point of entry into their system. However, it will work with anything that speaks HTTP and run on any platform that ASP.NET Core supports. Ocelot manipulates the HttpRequest object into a state specified by its configuration until it reaches a request builder middleware where it creates a HttpRequestMessage object which is used to make a request to a downstream service. The middleware that makes the request is the last thing in the Ocelot pipeline. It does not call the next middleware. The response from the downstream service is retrieved as the requests goes back up the Ocelot pipeline. There is a piece of middleware that maps the HttpResponseMessage onto the HttpResponse object and that is returned to the client. That is basically it with a bunch of other features! -

Octokit
Ruby toolkit for the GitHub API
API wrappers should reflect the idioms of the language in which they were written. Octokit.rb wraps the GitHub API in a flat API client that follows Ruby conventions and requires little knowledge of REST. Most methods have positional arguments for required input and an options hash for optional parameters, headers, or other options. While most methods return a Resource object or a Boolean, sometimes you may need access to the raw HTTP response headers. Access tokens can be revoked, removing access for only that token without having to change your password everywhere. Access tokens have access scopes that allow for more granular access to API resources. For instance, you can grant a third party access to your gists but not your private repositories. Two-Factor Authentication brings added security to the account by requiring more information to login. -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -
21
Serverless Webpack
Serverless plugin to bundle your lambdas with Webpack
A Serverless Framework plugin to build your lambda functions with Webpack. When enabled in your service configuration, functions are packaged and compiled individually, resulting in smaller Lambda packages that contain only the code and dependencies needed to run the function. This allows the plugin to fully utilize WebPack's Tree-Shaking optimization. Configuration possibilities range from zero-config to fully customizable. Support of serverless package, serverless deploy and serverless deploy function. Support of serverless invoke local and serverless invoke local --watch. Support of serverless run and serverless run --watch. Integrates with serverless-offline to simulate local API Gateway endpoints. Cleaned up configuration. You should now use a custom.webpack object to configure everything relevant for the plugin. The old configuration still works but will be removed in the next major release. -
