flow-json-component v0.3.4

Flow Json component

The component converts text to JSON and JSON to text and is designed using Flow SDK.

To get started, install the package in your NodeJS project

npm i flow-json-component --save

Use the component as below

// require the component
const Component = require('flow-json-component');

To change text to json

// create instance of the toJSON component
const component = new Component.toJSON();

// provide text to change to json
component.getProperty('Text').data = { name: "Allan Wise" };

To change json to text

// create instance of the fromJSON component
const component = new Component.fromJSON();

// provide json to change to text
component.getProperty('Text').data = '{"shape":"circle"}';

Listen in for port emit events

component.getPort('Success').onEmit(function(){
  // task succesfully ran
  // the result can be accessed through the 'Data' property of the port
  let result = component.getPort('Success').getProperty('Data').data;
});

component.getPort('Error').onEmit(function(){
  // an error occured
  // the actual error can be accessed through the 'Data' property of the port
  let err = component.getPort('Error').getProperty('Data').data;
});

Execute the component

// add the component to a graph before executing it
const Graph = require('flow-platform-sdk').Graph;
new Graph("graph-1").addComponent(component);

component.execute();

Conclusion

And that's the Flow Json component.
