Inject extra JavaScript while exporting
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
// Injecting custom JavaScript while exporting
const path = require('path');
// Require FusionExport
const { ExportManager, ExportConfig } = require('../');
// Instantiate ExportManager
const exportManager = new ExportManager();
// Instantiate ExportConfig and add the required configurations
const exportConfig = new ExportConfig();
exportConfig.set('chartConfig', path.join(dirname, 'resources', 'multiple.json'));
exportConfig.set('templateFilePath', path.join(dirname, 'resources', 'template.html'));
exportConfig.set('callbackFilePath', path.join(dirname, 'resources', 'callback.js'));
// provide the export config
exportManager.export(exportConfig);
// Called when export is done
exportManager.on('exportDone', (outputFileBag) => {
outputFileBag.forEach((op) => {
console.log(DONE: ${op.realName});
});
ExportManager.saveExportedFiles(outputFileBag);
});
// Called on each export state change
exportManager.on('exportStateChange', (state) => {
console.log([${state.reporter}] ${state.customMsg});
});
// Called on erroe
