Flux Standard Action JSON serialization

Flux Standard Action JSON serialization utilities.

npm install --save flux-standard-action-json

Usage

import fsaJSON from 'flux-standard-action-json';

stringify(action, ?options)

Returns a JSON string if action is FSA compliant. Otherwise, throws an error.

NOTE: Symbol action types should have a key. For example:

  fsaJSON.stringify({type: Symbol()});
  // throws an error

  fsaJSON.stringify({type: Symbol('ACTION_TYPE')});
  // returns '{"type":"Symbol(ACTION_TYPE)"}'

?options

• error: (Object) Error serialization options. Applies only if payload is an Error object. We depend on Errio so the same options apply.

Example:

  fsaJSON.stringify({
    type: 'ACTION_TYPE',
    error: true,
    new Error('Where?'))
  }, {error: {stack: true}});
  // returns '{"type":"ACTION_TYPE","error":true,"payload":{"name":"Error","message":"Where?","stack":"<a full error stack>"}}'

parse(json, ?options)

Returns an FSA compliant action parsed from a JSON string, parsing Symbol type and Error payload where applies.

Examples:

  fsaJSON.parse('{}');
  // throws an error

  fsaJSON.parse('{"type":"Symbol(ACTION_TYPE)"}');
  // returns {type: Symbol.for('ACTION_TYPE')}

  fsaJSON.parse('{"type":"TYPE","error":true,"payload":"Invalid something"}');
  // returns {type: 'TYPE', error: true, payload: new Error('Invalid something')}

NOTE: Symbol action types should have a key. For example:

  fsaJSON.parse('{"type":"Symbol()"}');
  // throws an error

?options

• error: (Object) Error deserialization options. Applies only if payload is an Error object. We depend on Errio so the same options apply.
