Zebra Savanna Data Services JavaScript SDK

This is the source code for the Savanna JavaScript SDK.
The core of this SDK is a basic API connection call to the Zebra Savanna Data Services in the SavannaAPI class. Currently the API has public methods for the three public APIs that are part of the Barcode Intelligence Product. These APIs are:

• Barcode Generate
• UPC Lookup
• FDA Recall

It is recommended to run this code from a web server with a domain name to avoid CORS errors.

API Key

To get an API key to work with these APIs, use the Getting Started Guide and select the Barcode Intelligence product.

Usage guide

Set Zebra Savanna API key

setApiKey("API-Key-Goes-Here");

Create Barcode

Create("Desired-Symbology", "Barcode-Value", scale, "Rotation", showValueText, baseApiKey)
    .then(data => {
        console.log("Create Barcode: " + data);
        var reader = data.body.getReader();
        window.image = document.createElement('img');
        document.body.appendChild(image);
        return new ReadableStream({
            start(controller) {
                return pump();
                function pump() {
                    return reader.read().then(({ done, value }) => {
                        // When no more data needs to be consumed, close the stream
                        if (done) {
                            controller.close();
