Usage

• Requires Node 12 or higher

+  .use(require('ssb-blobs'))
+  .use(require('ssb-blobs-blurhash'))
   .call(null, config)

API

ssb.blobsBlurhash.generate(blobId, opts, cb) (muxrpc "async")

• blobId: string: ssb blob id
• opts: { width: number, details }: options to use for generation.
  • width is the pixel width to resize your blob image to, for generating the hash. The smaller this number is, the quicker the algorithm will run, but with lower quality. The higher this number is, the higher the quality and the slower the algorithm will run.
  • details is a boolean that determines whether to return the hash (if false) or an object {hash, componentX, componentY} (if true)
• cb: (err: any, hash: string) => void: callback that provides the hash generated by blurhash

ssb.blobsBlurHash.generate('abc123', { width: 48 }, (err, hash) => {
    if (err) throw err

    console.log(`Blurhash result is ${hash}`)
})
