Connecting to JSON using the Data Compressor

In the previous article we described how to connect your web pivot table to a JSON data source. To gain even better performance while working with JSON datasets you can use Flexmonster Data Compressor – a server-side compression tool developed by our team. The Data Compressor helps you to increase data loading speeds from server to a customer’s browser.

The Data Compressor is available for Node.js. The following steps will help you with the process of connecting to JSON using the Data Compressor.

Step 1: Embed the component into your web page

Set up an empty component in your HTML page. If Flexmonster is not yet embedded – return to Quick start. Your code should look similar to the following example:

<div id="pivotContainer">The component will appear here</div>
<script src="flexmonster/flexmonster.js"></script>
<script>
	var pivot = new Flexmonster({
		container: "pivotContainer",
		toolbar: true,
		licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
	});
</script>

Step 2: Setup the Data Compressor on the server

To install Flexmonster Data Compressor run this command using NPM:

npm install flexmonster-compressor

Note that you need to have Node.js version 8.x.

Then add these lines that will convert your JSON file to a compressed stream:

const compressor = require('flexmonster-compressor');
let stream = compressor.compressJsonFile('data.json');

Ensure that you have specified the correct path to your JSON file. Now you can create a response from the stream:

stream.on('data', data => {
	res.write(data);
});
stream.on('end', () => {
	res.end();
});

The full project is available at Pivot Table for JSON/compressor/nodejs/ inside the download package.

Step 3: Enable cross-origin resource sharing (CORS)

By default, the browser prevents JavaScript from making requests across domain boundaries. CORS allows web applications to make cross-domain requests. Here is a useful link explaining how to setup CORS on your server:

Step 4: Configure report with your own data

Now it’s time to configure Flexmonster Pivot on the web page. Let’s create a minimal report for this (replace filename and other parameters with your specific values):

var pivot = new Flexmonster({
	container: "pivotContainer",
	toolbar: true,
	report: {
		dataSource: {
			dataSourceType: "ocsv",
			/* URL to the Data Compressor Node.js */
			filename: "http://localhost:3000/data"
		}
	},
	licenseKey: "XXXX-XXXX-XXXX-XXXX-XXXX"
});

Launch the web page from a browser — there you go! A pivot table is embedded into your project.
