Bruno
Opensource IDE For Exploring and Testing Api's
Bruno is a Fast and Git-Friendly Opensource API client, aimed at revolutionizing the status quo represented by Postman, Insomnia, and similar tools out there. Bruno stores your collections directly in a folder on your filesystem. We use a plain text markup language, Bru, to save information about API requests.

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. -

Serverless Express by Vendia
Run Node.js web applications and APIs using existing frameworks
Run REST APIs and other web applications using your existing Node.js application framework (Express, Koa, Hapi, Sails, etc.), on top of AWS Lambda and Amazon API Gateway. Vendia is the real-time data cloud for rapidly building applications that securely share data across departments, companies, clouds, and regions. We’re excited to announce the latest release of Vendia Share! This release includes new features like smart contracts, user-level transactions, the beta release of Azure support, and more. We also added a pay-as-you-go pricing plan that gives developers from organizations of any size access to Vendia's enterprise-grade platform for building data-driven, multi-party, cross-cloud apps. If you want to migrate an existing application to AWS Lambda, it's advised to get the minimal example up and running first, and then copy your application source in. -

AsyncAPI
Allows you to create machine-readable definitions of asynchronous APIs
AsyncAPI is an open-source initiative that seeks to improve the current state of Event-Driven Architecture (EDA). Our long-term goal is to make working with EDAs as easy as working with REST APIs. That goes from documentation to code generation, from discovery to event management, and beyond. The AsyncAPI Specification defines a standard, protocol-agnostic interface that describes message-based or event-driven APIs. The AsyncAPI document allows people or machines communicating with one another to understand the capabilities of an event-driven API without requiring access to the source code, documentation, or inspecting the network traffic. It allows you to define your API structures and formats, including channels the end user can subscribe to and the message formats they receive. You can develop, validate, and convert the AsyncAPI document to the latest version or preview your AsyncAPI document in a more readable way using the AsyncAPI Studio. -

Claudia Bot Builder
Create chat bots for Facebook Messenger, Slack, Amazon Alexa, etc.
Claudia Bot Builder helps developers create and deploy chat-bots for various platforms in minutes to AWS Lambda. It simplifies the messaging workflows, automatically sets up the correct web hooks, and guides you through configuration steps, so that you can focus on important business problems and not have to worry about infrastructure code. This code is enough to operate bots for all supported platforms. Claudia Bot Builder automatically parses the incoming messages into a common format, so you can handle it easily. It also automatically packages the response into the correct message template for the requesting bot, so you do not have to worry about individual bot protocols. Claudia Bot Builder doesn't have a stand-alone http server in the background (such as Express, Hapi, etc.), instead it uses API Gateway and it's not trivial to simulate similar environment locally. Deploy it with --version test to create a separate test environment directly in AWS Lambda. -

DataLoader
Generic utility to use with an application's data fetching layer
DataLoader is a generic utility to be used as part of your application's data fetching layer to provide a simplified and consistent API over various remote data sources such as databases or web services via batching and caching. A port of the "Loader" API originally developed by @schrockn at Facebook in 2010 as a simplifying force to coalesce the sundry key-value store back-end APIs which existed at the time. At Facebook, "Loader" became one of the implementation details of the "Ent" framework, a privacy-aware data entity loading and caching layer within web server product code. This ultimately became the underpinning for Facebook's GraphQL server implementation and type definitions. DataLoader is a simplified version of this original idea implemented in JavaScript for Node.js services. DataLoader is often used when implementing a graphql-js service, though it is also broadly useful in other situations. -

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. -

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. -

rest.js
GitHub REST API client for JavaScript
GitHub REST API client for JavaScript. Import the Octokit constructor based on your platform. Instantiate your octokit API. All options are optional, but authentication is strongly encouraged. API Previews can be enabled globally by setting the previews option. They can be set per-request as well. A default time zone can be enabled by setting the timeZone option. In order to use Octokit with GitHub Enterprise, set the baseUrl option. Most of GitHub’s REST API endpoints have matching methods. All endpoint methods are asynchronous, in order to use await in the code examples, we wrap them into an anonymous async function. Authentication is optional for some REST API endpoints accessing public data, but is required for GraphQL queries. Using authentication also increases your API rate limit.
