{"id":16547,"library":"teepee","title":"Teepee HTTP Client","description":"Teepee is a generic HTTP client for Node.js, currently at version 3.0.1. It provides basic functionality for making HTTP requests, akin to older-generation clients. The package has seen no significant code updates in approximately seven years, with its latest npm publication dating back five years (v3.0.1). This indicates the library is effectively abandoned and unmaintained. Unlike actively developed modern HTTP clients such as Axios or Node-Fetch, Teepee lacks native TypeScript support, a clear release cadence, and up-to-date documentation on its feature set or breaking changes between major versions. Its primary differentiator is its lightweight nature and adherence to older Node.js conventions for HTTP requests.","status":"abandoned","version":"3.0.1","language":"javascript","source_language":"en","source_url":"git://github.com/One-com/teepee","tags":["javascript"],"install":[{"cmd":"npm install teepee","lang":"bash","label":"npm"},{"cmd":"yarn add teepee","lang":"bash","label":"yarn"},{"cmd":"pnpm add teepee","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"While typically used with CommonJS `require`, a default import is likely for ESM environments given its age and common patterns for 'main' function exports.","wrong":"import { teepee } from 'teepee';","symbol":"teepee","correct":"import teepee from 'teepee';"},{"note":"This is the most common and expected import pattern for a package of this era and status.
