Installation

To install this module in your aranode project, you just need to add the package using following command:

$ yarn add @a-mehrabi/aranode-json-parser

After that, when you want to use it, you must include it in custom modules like the following:

path: .env

ARANODE_CUSTOM_MODULES=@a-mehrabi/aranode-json-parser

Usage

For using json encoder or decoder, you need to use encoder or decoder associated description:

1. json encoder flow description (jsonEncoder)
2. json decoder flow description (jsonDecoder)

json encoder

json encoder flow description enables you to define the json encoder as a flow node.
json encoder, encodes javascript literal object to json string.

version: 1
kind: flow
name: greeter-flow
entryPoint: start

flow:
  start:
    transform:
      path: 'dist/get-payload-transformer.js'
    nextNode: initJsonEncoder

  initJsonEncoder:
    jsonEncoder: {}
    nextNode: checkPayload

  checkPayload:
    transform:
      path: 'dist/check-payload-transformer.js'
    nextNode: response

  response:
    port:
      name: greet-in-port
      type: inbound
      response: true
      end: true
    terminal: true

json decoder

json decoder flow description enables you to define the json decoder as a flow node.
json decoder, decodes json string to javascript literal object.

version: 1
kind: flow
name: greeter-flow
entryPoint: start

flow:
  start:
    transform:
      path: 'dist/get-payload-transformer.js'
    nextNode: initJsonDecoder

  initJsonDecoder:
    jsonDecoder: {}
    nextNode: checkPayload

  checkPayload:
    transform:
      path: 'dist/check-payload-transformer.js'
    nextNode: response

  response:
    port:
      name: greet-in-port
      type: inbound
      response: true
      end: true
    terminal: true
