webmodules / blob Goto Github PK

Hi, I recently uploaded this Node.js module as a Debian package and we noticed that the license file is outdated. Can you please provide more details on the author(s) and the copyright holder(s)? This may seem a mundane task, but it makes the world better in protecting your work and the freedoms of the users. Many thanks, Paolo

This repo is practically abandoned. The latest versions published to NPM are at https://github.com/amitport/blob.
(I don't have github repo permissions but I do have NPM package permissions)

Kind of surprised there is a 0.0.5 version since it isn't a release in this repo. However 0.0.5 in npm include several development environment files. Shown in bold below.

I'm using Blob in node.js (v8.10.0) for creating a dummy file for the unit test. Below is my code

const Blob = require('blob');
let dummyFileData = new Uint8Array( [ 137, 80, 78, 71, 130 ] );
let dummyFileBlob = new Blob([ dummyFileData ], { type: 'image/png' });

Use some nice module for blob support in node.

I'm kind of confused since this project has only 10 stars, while at the same time there have been "77.762 downloads in the last day" and the last update was "rase- published 2 years ago".

So it looks like this project has been picked up again after some time and a few things were update. Would be sick to call it 1.0.0 and publish to npm so people know they can use it. Thanks!

there's a component.json, but this module doesn't support component currently. any way we could do something like:

var global = get_global_scope()

rather than assuming it's defined here?

how to covert base64 to blob

Please consider adding this fallback version if blob is unsupported

function FakeBlobBuilder() {

  function toUTF8Array(str) {
    var utf8 = [];
    for (var i=0; i < str.length; i++) {
      var charcode = str.charCodeAt(i);
      if (charcode < 0x80) utf8.push(charcode);
      else if (charcode < 0x800) {
        utf8.push(0xc0 | (charcode >> 6), 
        0x80 | (charcode & 0x3f));
      }
      else if (charcode < 0xd800 || charcode >= 0xe000) {
        utf8.push(0xe0 | (charcode >> 12), 
        0x80 | ((charcode>>6) & 0x3f), 
        0x80 | (charcode & 0x3f));
      }
      // surrogate pair
      else {
        i++;
        // UTF-16 encodes 0x10000-0x10FFFF by
        // subtracting 0x10000 and splitting the
        // 20 bits of 0x0-0xFFFFF into two halves
        charcode = 0x10000 + (((charcode & 0x3ff)<<10)
        | (str.charCodeAt(i) & 0x3ff));
        utf8.push(0xf0 | (charcode >>18), 
        0x80 | ((charcode>>12) & 0x3f), 
        0x80 | ((charcode>>6) & 0x3f), 
        0x80 | (charcode & 0x3f));
      }
    }
    return utf8;
  }

  function Blob(chunks, opts) {
    for (var i = 0, len = chunks.length; i < len; i++) {
      var chunk = chunks[i]
      chunks[i] = 
        chunk instanceof Blob ? chunk._buffer :
        typeof chunk === 'string' ? toUTF8Array(chunk) : chunk
    }

    this._buffer = [].concat.apply([], chunks)
    this.size = this._buffer.length
    this.type = opts ? opts.type || '' : ''
  }

  Blob.prototype.slice = function(start, end, type) {
    var slice = this._buffer.slice(start || 0, end || this._buffer.length)
    return new Blob([slice], type || '')
  }

  Blob.prototype.toString = function() {
    return '[object Blob]'
  }

  if (typeof Symbol !== 'undefined') {
    Blob.prototype[Symbol.toStringTag] = 'Blob'
  }

  return Blob
}

module.exports = (function() {
  if (blobSupported) {
    return blobSupportsArrayBufferView ? global.Blob : BlobConstructor;
  } else if (blobBuilderSupported) {
    return BlobBuilderConstructor;
  } else {
    return FakeBlobBuilder();
  }
})();
