The component evaluates an expression to true or false.
To use the component, in your NodeJS project, get it from npm registry
npm i flow-if-else-component --save
Use the component as below
// require the component
const Component = require('flow-if-else-component');
// create instance of the component
const component = new Component();Provide the expression
// this can be any javascript expression, '[].length', 'a==1', ' ' and more
component.getProperty('Expression').data = 'q=1'; That's all, now listen in for port emit events
component.getPort('True').onEmit(function() {
// the expression evaluated to true
});
component.getPort('False').onEmit(function() {
// the expression evaluated to false
});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();That's all required to use Flow's If-else component.
