tlsclientwrapper

TlsClientWrapper

A wrapper for bogdanfinn/tls-client based on ffi-rs for unparalleled performance and usability. Inspired by @dryft/tlsclient.

Installation

With npm:

npm install tlsclientwrapper

Information

This module, compared to bogdanfinn's example, offers:

1. Advanced JSDocs for faster development.
2. Use of the more updated ffi-rs.
3. Automatic conversations, session support, etc.
4. Default settings compatible with bogdafinn's client.
5. Built-in automatic retries on specific status codes.
6. Automatic download of the required library file.
7. Many more enhancements!

Usage

Simple Get Request:

import tlsClient from 'tlsclientwrapper';
const client = new tlsClient();

console.log(await client.get("https://example.com/"));

Default Headers/Cookies for all Requests:

import tlsClient from 'tlsclientwrapper';
const client = new tlsClient({
    defaultHeaders: {
        "Custom-Header": "Custom-Value",
        "User-Agent": "TlsClient/1.0"
    },
    defaultCookies: [
        {
            domain: "example.com",
            expires: 0,
            name: "testCookie",
            path: "/",
            value: "testValue"
        }
    ]
});

console.log(await client.get("https://myhttpheader.com/"));

TLS Request

Don't worry, all requests by default are sent imitating chrome_120 TLS

import tlsClient from 'tlsclientwrapper';
const client = new tlsClient({
    tlsClientIdentifier: "chrome_120" // For alternatives, check the docs or the JSDocs
});

console.log(await client.get("https://tls.peet.ws/api/all"));

Custom Library

import tlsClient from 'tlsclientwrapper';
import path from 'node:path';
const client = new tlsClient({
    customLibraryPath: path.join(process.cwd(), 'lib', 'customLib.dll') // Path must be complete
    //customLibraryDownloadPath: path.join(process.cwd(), 'lib') -> Can also be set if wanted, else os.temp or process.cwd is used.
});

console.log(await client.get("https://example.com/"));

⚠️ Warning ⚠️ All the JSDocs are currently based on the TLSClient Version 1.7.2, if you're using a custom LibraryPath it will not update the JSDocs.
