148tls-fetch

148tls-fetch

curl_cffi-like HTTP client emitting a real Chrome 148 TLS ClientHello + HTTP/2 fingerprint. Engine: Rust (wreq / BoringSSL) compiled to a native Node addon via napi-rs.

Platform: Windows x64 only. (os: win32, cpu: x64)

Install

npm install 148tls-fetch

Usage

const { CurlSession, Curl, CurlOpt, CurlInfo } = require("148tls-fetch");

const s = new CurlSession({ impersonate: "chrome148", proxy: "http://user:pass@host:port" });

const r = await s.get("https://x.com/", {
  headers: { "User-Agent": "Mozilla/5.0 ... Chrome/148.0.0.0 Safari/537.36" },
  timeout: 20000,
});
console.log(r.status, r.text.length);
// r = { status, url, text, data, dataRaw(Buffer), headers, headersList }

// cookies persist in s.jar across requests automatically
s.jar.setCookieSync("auth_token=...; Domain=.x.com; Path=/; Secure", "https://x.com/");

const post = await s.post("https://api.example.com/x", JSON.stringify({ a: 1 }), {
  headers: { "Content-Type": "application/json" },
});

Low-level handle (curl-cffi Curl style)

const c = new Curl();
c.impersonate("chrome148", false);
c.setOption(CurlOpt.Url, "https://example.com/");
c.setOption(CurlOpt.HttpGet, true);
c.setHeadersRaw(["User-Agent: ...", "Accept: application/json"]);
await c.perform();
c.status();                                  // HTTP status
c.getRespBody();                             // Buffer
c.getInfoString(CurlInfo.EffectiveUrl);      // final URL after redirects
c.close();

Fingerprint

Matches real Chrome 148 on JA4, HTTP/2 Akamai, cipher list, supported groups, and extension set. (JA3 hash intentionally varies — Chrome 110+ randomizes TLS extension order each handshake; JA4 is the stable identifier.)
