Several popular libraries are available for making HTTP requests in Node.js, including the built-in `http` and `https` modules, Got, Axios, SuperAgent, and node-fetch. Each library has its own strengths and weaknesses, with varying levels of complexity and functionality. For example, the built-in `http` module requires manual parsing of response data and does not support HTTPS by default, while Got is a lightweight library that uses promises and is easy to use, but does not parse JSON responses automatically. Axios is another popular option that parses JSON responses by default and allows for concurrent requests with `axios.all`. SuperAgent offers additional functionality such as query parameters and automatic parsing of response data. node-fetch is a lightweight module that brings the browser library `window.fetch` to Node.js with minimal code. The choice of library depends on the specific needs of the project, including desired level of complexity and functionality.
