BEHEMOTH

hashed blob storage. on opfs. in memory. on disk. in orbit.

• 🗿 behemoth stores binary data, anywhere.
• 🔒 content-addressable -- sha256 hashes for identity (never store a dupe)
• 🔮 blob-oriented -- blobs provide random-access and are generally super cool
• 🏞️ stream-oriented -- streams allow you to upload/download big stuff smoothly
• ♻️ isomorphic -- runs in browsers or node
• 🛰️ remote -- (coming soon) connect to a remote behemoth api service

🐉 abstract Behemoth

all behemoths have the same shape

Behemoth

• .has(hash: Hash): Promise<boolean>

  const exists = await behemoth.has(hash)

• .require(hash: Hash): Promise<Blob>

  const blob = await behemoth.require(hash)

• .get(hash: Hash): Promise<Blob | undefined>

  const blob = await behemoth.get(hash)

• .set(blob: Blob, options?: SetOptions): Promise<Hash>

  const hash = await behemoth.set(blob)

  const hash = await behemoth.set(blob, {
    onProgress: progress => {
      progress.total // number, total amount of work
      progress.done // number, amount of work completed
    },
  })

• .delete(...hashes: Hash[]): Promise<void>

  await behemoth.delete(hash)

🐉 BehemothOpfs

store data in the browser's origin private file system

import {BehemothOpfs} from "@e280/behemoth"

const behemoth = await BehemothOpfs.mkdir("my-data")

🐉 BehemothDisk

store data to disk via node fs

import {BehemothDisk} from "@e280/behemoth/node"
 //                                         👆

const behemoth = await BehemothDisk.mkdir("./my-data")

🐉 BehemothMemory

store data in memory

import {BehemothMemory} from "@e280/behemoth"

const behemoth = new BehemothMemory()

🐉 tools

handy tools you might wanna use

• hashBlob(blob: Blob, onProgress: (hashed: number) => void): Promise<Hash>

  const hash = await hashBlob(blob)

  const hash = await hashBlob(blob, hashed => {
    console.log(`bytes hashed: ${hashed}`)
  })

• readBlob(blob: Blob): AsyncGenerator<Uint8Array>

  for await (const chunk of readBlob(blob))
    chunk

• readStream(stream: ReadableStream<Uint8Array>): AsyncGenerator<Uint8Array>

  for await (const chunk of readStream(stream))
    chunk
