Description

jBinary makes it easy to create, load, parse, modify and save complex binary files and data structures in both browser and Node.js.

It works on top of jDataView (DataView polyfill with convenient extensions).

Was inspired by jParser and derived as new library with full set of operations for binary data.

jBinary

Binary data in JavaScript is easy!

jBinary makes it easy to create, load, parse, modify and save complex binary files and data structures in both browser and Node.js.

It works on top of jDataView (DataView polyfill with convenient extensions).

Was inspired by jParser and derived as new library with full set of operations for binary data.

How can I use it?

Typical scenario:

Describe typeset with JavaScript-compatible declarative syntax (jBinary will do type caching for you).
Create jBinary instance from memory or from data source and your typeset.
Read/write data just as native JavaScript objects!

API Documentation.

Check out wiki for detailed API documentation.

Is there any example code?

How about TAR archive modification:

// configuring paths for Require.js
// (you can use CommonJS (Component, Node.js) or simple script tags as well)
require.config({
  paths: {
    jdataview: 'https://jdataview.github.io/dist/jdataview',
    jbinary: 'https://unpkg.com/[email protected]/dist/browser/jbinary',
    TAR: 'https://jdataview.github.io/jBinary.Repo/typeSets/tar' // TAR archive typeset
  }
});

require(['jbinary', 'TAR'], function (jBinary, TAR) {
  // loading TAR archive with given typeset
  jBinary.load('sample.tar', TAR).then(function (jb/* : jBinary */) {
    // read everything using type aliased in TAR['jBinary.all']
    var files = jb.readAll();

    // do something with files in TAR archive (like rename them to upper case)
    files.forEach(function (file) {
      file.name = file.name.toUpperCase();
    });

    jb.writeAll(files, 0); // writing entire content from files array
    jb.saveAs('sample.new.tar'); // saving file under given name
  });
});

Run or edit it on JSBin.

Show me amazing use-cases!
