You can add a custom JavaScript file while exporting using the --callbackFilePath option. You can also use this option if you want to change the background style of the dashboard or resize the chart while exporting.
To do this, you can use the CLI or SDKs of the languages mentioned below, using the commands given below:

You can add a custom javascript file while exporting using the --callbacks, or -b, option. Here’s an example of a custom JavaScript that can be included while the export is happening.

The content of the custom.js file is as below:
document.body.style.transform = "rotate(-10deg)";
Once done, run the following command:
$ fe -c chart.json -b custom.js
const fs = require('fs');
const path = require('path');

// require fusionexport
const FusionExport = require('../');

const chartConent = fs.readFileSync(path.resolve(__dirname, 'dashboard_charts.json')).toString();
const chartConfig = JSON.parse(chartConent);
const host = '127.0.0.1';
const port = 1337;

// instantiate FusionExport
const fusion = new FusionExport({ host, port });

const exportConfig = {
  chartConfig,
  templateFilePath: path.join(__dirname, 'template.html'),
  callbackFilePath: path.join(__dirname, 'callback.js'),
};

fusion.export(exportConfig);

fusion.on('exportDone', (files) => {
  // files can be read from files array
  // e.g. [{tmpPath:"", realName: ""}]
});

fusion.on('exportStateChange', (state) => {
  // called for export progress state change
});

fusion.on('error', (err) => {
  // catch error here
});
