Zstd (Zstandard) binding for Nodejs, with TypeScript, AMD64 & ARM64 support.

Installation

$ npm install @skhaz/zstd --save

Usage

Async

compress(buffer[, zstdCompressParams])

import { compress } from '@skhaz/zstd'

try {
  const output = await compress(input)
} catch (err) {
  // ...
}

decompress(buffer[, zstdDecompressParams])

import { decompress } from '@skhaz/zstd'

try {
  const output = await decompress(input)
} catch (err) {
  // ...
}

Sync

compressSync(buffer[, zstdCompressParams])

import { compressSync } from '@skhaz/zstd'

try {
  const output = compressSync(input)
} catch (err) {
  // ...
}

decompressSync(buffer[, zstdCompressParams])

import { decompressSync } from '@skhaz/zstd'

try {
  const output = decompressSync(input)
} catch (err) {
  // ...
}

Stream

compressStream([zstdCompressParams])

import { compressStream } from '@skhaz/zstd'
import { createReadStream, createWriteStream } from 'fs'

createReadStream('path/to/input').pipe(compressStream()).pipe(createWriteStream('path/to/output'))

decompressStream([zstdCompressParams])

import { decompressStream } from '@skhaz/zstd'
import { createReadStream, createWriteStream } from 'fs'

createReadStream('path/to/input').pipe(decompressStream()).pipe(createWriteStream('path/to/output'))

ZSTD Params

The compress, compressSync and compressStream methods may accept an optional zstdCompressParams object to define compress level and/or dict.

const zstdCompressParams = {
  level: 5, // default 1
  dict: new Buffer('hello zstd'), // if dict null, left level only.
  dictSize: dict.length, // if dict null, left level only.
}

The decompress, decompressSync and decompressStream methods may accept an optional zstdDecompressParams object to define dict.

const zdtdDecompressParams = {
  dict: new Buffer('hello zstd'),
  dictSize: dict.length,
}

Tests
