PlotlyChartExport uses Phantom.js to render plot.ly charts on the server. It crops the chart, base64 encodes it and returns the encoded chart in a resolving promise. It does not rely on the filesystem nor does it rely on graphics libraries like Cairo making it an effective chart rendering solution for serverless environments.

• Only 1 Dependency
• Works in Serverless Environments
• Size < 10MB

npm install plotlychartexport --save 

/// include library const exp = require('plotlychartexport'); /// define plot.ly data properties let trace1 = { x: [1, 2, 3, 4], y: [10, 15, 13, 17], type: 'scatter' }; let trace2 = { x: [1, 2, 3, 4], y: [16, 5, 11, 9], type: 'scatter' }; /// define plot.ly layout let layout = { title: 'Line and Scatter Plot' }; /// run render command exp.render([trace1, trace2], layout).then((base) => { console.log(base); /// base64 }, (error) => { console.error(error); })
