Encode-object NPM

encode-object

Encodes and decodes JS objects in Base62. Useful for maintaining state in a URL hash. Right now, only works with ints.

Usage

createEncoder takes a config which maps each key it should find in an object to a [max, min, step]. step is optional and defaults to 1.

const config = {
  foo: [0, 5],
  bar: [10, 1000, 10],
  baz: [0, 1],
  qux: [-10, 10, 2],
};

const obj = {
  foo: 3,
  bar: 250,
  baz: 0,
  qux: -6,
};

const { encodeObject, decodeObject } = createEncoder(config);
encodeObject(obj); // returns '601BU'
decodeObject('601BU'); // returns object with the same keys and values as `obj`
