Unirest
Kong
FreeUnirest is a collection of lightweight HTTP libraries developed and supported by Kong, the same entity that oversees the open-source API Gateway known as Kong. To get started with Unirest in a Node.js environment, you need to install the npm package. You might be curious about how Unirest simplifies the process of making requests. In addition to automatically handling gzip compression and parsing responses, Unirest offers straightforward examples to illustrate its functionality. A request can be initiated by calling the relevant method on the Unirest object, followed by the .end() function to dispatch the request. Alternatively, you can directly send the request by providing a callback alongside the URL. The library provides user-friendly methods that allow for manipulation of the request before it is dispatched. When a Unirest method is called, a request object is generated, which includes chainable methods similar to those found in libraries like jQuery and the widely-used Superagent request module, which serves as a partial model for this library. With these features, developers can enjoy a more efficient and intuitive experience when working with HTTP requests. -
