🖥 Platform Support

Pre-compiled binaries for every platform and every language — no compiler required, works out of the box.

📦 Installation — 4 registries, 1 core

All four packages ship the same native core. The Python wheel additionally bundles the HTTP middleware suite.

🧩 What each SDK gives you

⚡ Performance at a Glance

🚀 Quick Start

The shared core (all 4 languages)

Response cache, bloom filter and circuit breaker — the same native primitives in every SDK. Contract-tested in all four.

Node.js

const { ResponseCache, BloomFilter, CircuitBreaker } = require('b4n1-boost/core.js');

const cache = new ResponseCache(1024);                       // capacity
cache.set('user:1', JSON.stringify({ id: 1 }), 200, 60);    // key, body, status, ttl (s)

const seen = new BloomFilter(100_000, 0.01);                // expected items, fp rate
if (!seen.checkAndSet('already-processed')) { /* first time we see it */ }

const breaker = new CircuitBreaker(5, 2, 30);               // threshold, successes, timeout (s)
if (!breaker.allows()) return fallback();

.NET

using B4N1.Boost;

using var cache = new NativeResponseCache(1024);
cache.Set("user:1", Encoding.UTF8.GetBytes("{\"id\":1}"), 200, 60);

using var seen = new NativeBloomFilter(100_000, 0.01);
bool firstTime = !seen.CheckAndSet("already-processed");

var breaker = new NativeCircuitBreaker(5, 2, 30);
if (!breaker.Allows) return Fallback();

Java / Kotlin

import com.b4n1.boost.NativeResponseCache;

try (NativeResponseCache cache = new NativeResponseCache(8)) {
    cache.set("user:1", "{\"id\":1}".getBytes(StandardCharsets.UTF_8), 200, 60_000);
}

Python

from b4n1_boost import ResponseCache

cache = ResponseCache(1024, 60)                   # capacity, default TTL (s)
cache.set("user:1", b'{"id":1}', [], 200)         # key, body, headers, status

Compression engine

Node.js

const boost = require('b4n1-boost');

const zstd = boost.compressZstd(payload);      // 28x faster than gzip
const back = boost.decompressZstd(zstd);
const min  = boost.minifyHtml(html);

.NET

var zstd = NativeBoost.CompressZstd(payload);

Java / Kotlin

byte[] zstd = Boost.compressZstd(data, 3);

Express / ASP.NET middleware

const express = require('express');
const boostMiddleware = require('b4n1-boost/express');

app.use(boostMiddleware({ minifyHtml: true, gzipLevel: 4 }));

📚 Full usage for every language lives in the manual.

🐍 Python suite (middleware + accelerators)

The Python package is the most complete one: everything above, plus the HTTP middleware suite and the framework accelerators.

pip install b4n1-boost

🔧 Features

JSON Serialization (10x faster)

from b4n1_boost import NativeJson, canonicalize_json, validate_json

# Fast JSON dumps (native engine, 10x faster)
result = NativeJson.dumps({"users": [...]})

# Direct native path (no intermediate conversion)
result = NativeJson.dumps_direct(data)

# Batch: serialize N objects in a single GIL acquire
results = NativeJson.batch_dumps([obj1, obj2, obj3])

# Canonicalize: sorted keys, compact form (accepts str or dict)
canonicalize_json({"z": 1, "a": 2})  # '{"a":2,"z":1}'

# Fast JSON validation
validate_json('{"valid": true}')  # True

Compression (28x faster, GIL-free)

from b4n1_boost import compress

compressed = compress(payload, "zstd")   # 28x faster than stdlib gzip
compressed = compress(payload, "brotli") # Best ratio
compressed = compress(payload, "gzip")   # 1.47x faster than stdlib

# Static file compression
from b4n1_boost import compress_static_file, compress_static_dir
compress_static_file("app/static/app.js", algorithm="zstd")
compress_static_dir("app/static/", algorithm="zstd")

from b4n1_boost.middleware import B4N1BoostCompressionMiddleware

# Automatically skips: images, video, audio, fonts, archives, already-compressed
app.wsgi_app = B4N1BoostCompressionMiddleware(app.wsgi_app, min_size=1024)

# For FastAPI/ASGI (streaming support)
from b4n1_boost.middleware import FastAPIBoostCompressionMiddleware
app.add_middleware(FastAPIBoostCompressionMiddleware)
