Open Source TypeScript API Gateways

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.

Firecamp is a DX-first API development platform that helps developers design, develop, test, and document their APIs effortlessly. With a user-friendly interface and a range of powerful features, Firecamp streamlines the API development workflow and enhances collaboration among team members.

Anyrow SDK (@anyrow/sdk) is the official TypeScript/JavaScript client for the Anyrow API — AI-native document extraction with built-in structured storage. Extract clean rows from PDFs, images, emails, calls, and websites. Manage tables, rows, batches, live extraction streams, and exports via a single typed client. Runs in browsers and on Node, Bun, Deno, and Cloudflare Workers — any runtime with `fetch`. Install: npm install @anyrow/sdk Quick start: import { AnyrowSDK } from "@anyrow/sdk" const client = new AnyrowSDK({ baseURL: "https://api.anyrow.ai", headers: { Authorization: "Bearer KEY" }}) await client.extract.once({ params: { project_id: "proj_123" }, json: { url: "https://example.com/doc.pdf" }}) Open source (MIT). Generated from the Anyrow OpenAPI spec. Also on JSR as @anyrow/sdk.

APIPark is an open-source, all-in-one AI gateway and API developer portal, that helps developers and enterprises easily manage, integrate, and deploy AI services. No matter which AI model you use, APIPark provides a one-stop integration solution. It unifies the management of all authentication information and tracks the costs of API calls. Standardize the request data format for all AI models. When switching AI models or modifying prompts, it won’t affect your app or microservices, simplifying your AI usage and reducing maintenance costs. You can quickly combine AI models and prompts into new APIs. For example, using OpenAI GPT-4 and custom prompts, you can create sentiment analysis APIs, translation APIs, or data analysis APIs. API lifecycle management helps standardize the process of managing APIs, including traffic forwarding, load balancing, and managing different versions of publicly accessible APIs. This improves API quality and maintainability.

The AWS Toolkit extension for Visual Studio Code enables you to interact with Amazon Web Services (AWS). Try the AWS Code Sample Catalog to start coding with the AWS SDK. The AWS Explorer provides access to the AWS services that you can work with when using the Toolkit. To see the AWS Explorer, choose the AWS icon in the Activity bar. The Developer Tools panel is a section for developer-focused tooling curated for working in an IDE. The Developer Tools panel can be found underneath the AWS Explorer when the AWS icon is selected in the Activity bar. The AWS CDK Explorer enables you to work with AWS Cloud Development Kit (CDK) applications. It shows a top-level view of your CDK applications that have been synthesized in your workspace. Amazon CodeWhisperer provides inline code suggestions using machine learning and natural language processing on the contents of your current file. Supported languages include Java, Python and Javascript.

Got implements RFC 7234 compliant HTTP caching which works out of the box in-memory and is easily pluggable with a wide range of storage adapters. Got uses Keyv internally to support a wide range of storage adapters. For something more scalable you could use an official Keyv storage adapter. Hooks allow modifications during the request lifecycle. Hook functions may be async and are run serially. Got will make no further changes to the request before it is sent. This is especially useful in conjunction with got.extend() when you want to create an API client that, for example, uses HMAC-signing. You can override the request function by returning a ClientRequest-like instance or a IncomingMessage-like instance. This is very useful when creating a custom cache mechanism. The response object will typically be a Node.js HTTP response stream, however, if returned from the cache it will be a response-like object which behaves in the same way.

Yaak is a modern desktop API client designed to provide a fast, intuitive, and privacy-focused environment for interacting with APIs across multiple protocols. It supports a wide range of technologies including REST, GraphQL, gRPC, WebSocket, and Server-Sent Events, allowing developers to work with different types of APIs from a single unified interface. The application is built using Tauri, Rust, and React, which contributes to its lightweight footprint, high performance, and cross-platform compatibility. One of its core design principles is being offline-first, meaning that user data, requests, and secrets are stored locally without reliance on cloud services, enhancing both privacy and control. Yaak also emphasizes developer productivity by offering features such as dynamic request templating, debugging tools, and environment-based configuration management.

Shared API definitions based on Zod. Standalone typesafe API client based on Axios with parameters and response validation. Typesafe server based on Express with input validation. Really simple centralized API declaration, typescript autocompletion in your favorite IDE for URL and parameters, and typescript response types. Parameters and responses schema thanks to Zod, response schema validation, and powerful plugins like fetch adapter or auth automatic injection.
