The robust request library that humanity deserves π
This package provides highly likely functional and easy-to-use abstraction atop of native http(s).request and http2.request.
Abstract
- Fetch-alike
- Cool-beans π« config options (with defaults)
- Automatic HTTP/2 support (ALPN negotiation)
- Automatic or opt-in body parse (with non-UTF-8 charset decoding)
- Automatic and simplistic
Cookies
treatment (with built-in jar & ttl) - Automatic decompression (with opt-in body compression)
- Built-in streamable
FormData
interface - Support redirects & retries with fine-grained tune-ups
- Support all legit request body types (include blobs & streams)
- Support both CJS and ESM module systems
- Fully promise-able and pipe-able
- Zero dependencies
Prerequisites
- Node.js
>= 18.13.0
Installation
npm install rekwest --save
Usage
import rekwest, { constants } from 'rekwest';
const {
HTTP2_HEADER_AUTHORIZATION,
HTTP2_HEADER_CONTENT_ENCODING,
HTTP2_METHOD_POST,
HTTP_STATUS_OK,
} = constants;
const url = 'https://somewhe.re/somewhat/endpoint';
const res = await rekwest(url, {
body: { celestial: 'payload' },
headers: {
[HTTP2_HEADER_AUTHORIZATION]: 'Bearer [token]',
[HTTP2_HEADER_CONTENT_ENCODING]: 'br', // enables: body compression
/** [HTTP2_HEADER_CONTENT_TYPE]
* is undue for
* Array/Blob/File/FormData/Object/URLSearchParams body types
* and will be set automatically, with an option to override it here
*/
},
method: HTTP2_METHOD_POST,
});
console.assert(res.statusCode === HTTP_STATUS_OK);
console.info(res.headers);
console.log(res.body);

rekwest.defaults
The object to fulfill with default options.
rekwest.extend(options)
The method to extend default options per instance.
import rekwest, { constants } from 'rekwest';
const {
HTTP_STATUS_OK,
} = constants;
const rk = rekwest.extend({
baseURL: 'https://somewhe.re',
});
const signal = AbortSignal.timeout(1e4);
const url = '/somewhat/endpoint';
const res = await rk(url, {
signal,
});
console.assert(res.statusCode === HTTP_STATUS_OK);
console.info(res.headers);
console.log(res.body);
rekwest.stream(url[, options])
The method with limited functionality to use with streams and/or pipes.
- No automata (redirects & retries)
- Pass
h2: true
in options to use HTTP/2 protocol- Use
ackn({ url: URL })
method in advance to check the available protocols
- Use
import fs from 'node:fs';
import { pipeline } from 'node:stream/promises';
import rekwest, {
ackn,
constants,
} from 'rekwest';
const {
HTTP2_METHOD_POST,
} = constants;
const url = new URL('https://somewhe.re/somewhat/endpoint');
const options = await ackn({ url });
await pipeline(
fs.createReadStream('/path/to/read/inlet.xyz'),
rekwest.stream(url, { ...options, method: HTTP2_METHOD_POST }),
fs.createWriteStream('/path/to/write/outlet.xyz'),
);
