    Got

    Got

    Human-friendly and powerful HTTP request library for Node.js

    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

    Yaak

    The most intuitive desktop API client

    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.

    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.
