    Google APIs Node.js Client

    Google APIs Node.js Client

    Google's supported Node.js client library

    Google's supported Node.js client library for accessing Google APIs. Support for authorization and authentication with OAuth 2.0, API Keys and JWT (Service Tokens) is included. The full list of supported APIs can be found on the Google APIs Explorer. The API endpoints are automatically generated, so if the API is not in the list, it is currently not supported by this API client library. These client libraries are supported by Google. However, these libraries are considered complete and are in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features. For Google Cloud Platform APIs, we recommend using google-cloud-node which is under active development. This library supports the maintenance LTS, active LTS, and current release of node.js.

    AWS SAM CLI

    AWS SAM CLI

    CLI tool to build, test, debug, and deploy Serverless applications

    The AWS Serverless Application Model (SAM) CLI is an open-source CLI tool that helps you develop serverless applications containing Lambda functions, Step Functions, API Gateway, EventBridge, SQS, SNS and more. The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings. With just a few lines per resource, you can define the application you want and model it using YAML. During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax, enabling you to build serverless applications faster. To get started with building SAM-based applications, use the SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, debug, and deploy AWS serverless applications.

    OpenAPI Generator

    OpenAPI Generator

    OpenAPI Generator allows generation of API client libraries

    With 50+ client generators, you can easily generate code to interact with any server which exposes an OpenAPI document. Maintainers of APIs may also automatically generate and distribute clients as part of official SDKs. Each client supports different options and features, but all templates can be replaced with your own Mustache-based templates. Getting started with server development can be tough, especially if you're evaluating technologies. We can reduce the burden when you bring your own OpenAPI document. Some generators support Inversion of Control, allowing you to iterate on design via your OpenAPI document without worrying about blowing away your entire domain layer when you regenerate code. Ever wanted to iteratively design a MySQL database, but writing table declarations was too tedious? OpenAPI documents allow you to convert the metadata about your API into some other format.

    Swagger Core

    Swagger Core

    Examples, server integrations for generating Swagger API Specification

    Swagger Core is a Java implementation of the OpenAPI Specification. Current version supports JAX-RS2 (javax and jakarta namespaces). One of the common usage scenarios is to integrate swagger-jaxrs2 into an existing or new JAX-RS based project ("code-first"), to automatically provide and expose its APIs definition, which is kept in sync during the project lifecycle. Such definition can be the base for further processing/consumption, including API documentation (e.g with swagger-ui, API client generation in various languages (e.g with swagger-codegen), custom processing, and so on. Such result is achieved by scanning JAX-RS resources and resolving their operations and used types, (also) processing applied annotations (e.g. Swagger, JAX-RS, Jackson, JAXB, etc.). An extension mechanism allows to further customize and pre/post processing result.

    ThetaGang

    ThetaGang

    ThetaGang is an IBKR bot for collecting money

    ThetaGang is an IBKR trading bot for collecting premiums by selling options using "The Wheel" strategy. The Wheel is a strategy that surfaced on Reddit but has been used by many in the past. This bot implements a slightly modified version of The Wheel, with my own personal tweaks. The strategy, as implemented here, does a few things differently from the one described in the post above. For one, it's intended to be used to augment a typical index-fund-based portfolio with specific asset allocations. For example, you might want to use a 60/40 portfolio with SPY (S&P500 fund) and TLT (20-year treasury fund). This strategy reduces risk, but may also limit gains from big market swings. By reducing risk, one can increase leverage. ThetaGang will try to acquire your desired allocation of each stock or ETF according to the weights you specify in the config. To acquire the positions, the script will write puts when conditions are met.

    API Umbrella is an open source API management platform for exposing web service APIs. The basic goal of API Umbrella is to make life easier for both API creators and API consumers. APIs can assume the boring stuff (access control, rate limiting, analytics, etc.) is already taken care if the API is being accessed, so common functionality doesn't need to be implemented in the API code. API Umbrella acts as a layer above your APIs, so your API code doesn't need to be modified to take advantage of the features provided.

    AsyncAPI

    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.
