impit for JavaScript

Note: This is the documentation of the Node.JS bindings for the impit library.

impit is a Node.JS module that provides bindings for the impit library.

It allows you to switch the TLS fingerprints and the HTTP headers of your requests, while still using the same API as the built-in (since Node.JS 18) fetch function.

Installation

npm install impit

Installing the root package (impit) with the package manager of your choice will also install the correct prebuilt binary for your platform.

    ignoreTlsErrors: true,
});

// Use the `fetch` method as you would with the built-in `fetch` function
const response = await impit.fetch("https://example.com");

console.log(response.status);
console.log(response.headers);
console.log(await response.text());
