`dscc` (Data Studio Community Component) is a library to help with the building of community components for Google Data Studio. It can be used as a standalone library, or as a npm dependency.

const dscc = require('@google/dscc');
const viz = require('@google/dscc-scripts/viz/initialViz.js');
const local = require('./localMessage.js');

// change this to 'true' for local development
// change this to 'false' before deploying
export const LOCAL = false;

// write viz code here
const drawViz = (data) => {
  document.body.innerText = JSON.stringify(data);
};

// renders locally
if (LOCAL) {
  drawViz(local.message);
} else {
  dscc.subscribeToData(drawViz, {transform: dscc.objectTransform});
