phn

A lightweight HTTP client that works seamlessly with node and bun:

• http2 support with per-origin session
• http1 keepalive-agent by default
• compression support with fallback zstd support via fzstd when installed
• optional decode support via iconv-lite when installed
• works with async/await, promises and callbacks
• tiny and comes with no required dependencies
• 200% test coverage (we run every test at least twice for good measure)

phn is an interface-compatible, drop-in replacement for the abandoned phin

install

npm i phn

usage

const phn = require("phn");

const res = await phn({
	url: 'https://example.org'
});

options

• method - string; default: GET
• url - string or URL object
• core - object; passed on to http(s).request
• http2 - object; passed on to http2.request; false to disable http2 support
• headers - object; request headers
• query - object; added to url as query string
• data - object, buffer, typed array; sent as data in POST request
• form - object; sent as application/x-www-form-urlencoded
• parse - "json", "string", or function(body); parse response body
• follow - follow redirects if true, limit if Number (default: 20)
• stream - return stream as res.stream instead of res.body
• compression - bool or string, string overrides accept-encoding header, default: true
• decode - bool or string; use iconv-lite to decode stream if available
• timeout - request timeout in milliseconds
• maxBuffer - maximum response buffer size

stream

consume http response as stream

const phn = require("phn");

const resp = await phn({
	url: 'https://example.org/',
	compression: true,
	stream: true,
});

resp.stream.pipe(/* ... */)

custom http(s) options

use a custom agent for http and https

const phn = require("phn");
const https = require("https");

const agent = new SocksProxyAgent(/* ... */);

await phn({
	url: 'https://example.org/',
	core: { agent },
	http2: false
});

unpromisified

builtin classic callback interface

const phn = require("phn");

phn('https://example.org/', (err, res) => {
	if (!err) console.log(res.body);
});

defaults

set options for any subsequent request

const phn = require("phn").defaults({
	method: 'POST',
	parse: 'json',
	timeout: 2000
});

const res = await phn('https://example.org/');

zstd support

bun and node <=22 don't support zstd compression, but phn can handle zstd when fzstd is available

npm i fzstd

decode support

phn can decode various character encodings via the decode option when iconv-lite is installed

npm i iconv-lite
