The web server was designed to provide an easy to use barcode generation API via the HTTP protocol for use in external / mobile applications where generation libraries might not exist or resources limited; the WebUI is also designed to be responsive such that users may generate barcodes to be scanned directly from their web browser or download the barcodes after testing them out.

Web Server

The server comes with a minimal set of static HTML and Javascript files that allow users to generate barcodes in their web browser with ease. The UI allows users to quickly download, print, or copy the images for use in other applications.

API Server

The server will generate a barcode for any content passed to the /api endpoint; this can be done using a web browser, fetched through a user script, or even simply with cURL.

Automatic Code Type Detection

When calling the API endpoint without specifying an eplitit code type the server will make its best judgement as to which code type will be best suited for the supplied data.


Defined Code Type

A list of all supported barcodes types is available by calling the /types/ endpoint; this will be a JSON Array containing details for each type including a regex format to prevalidate the date before a request.

Specific barcode types may be requested by adding the type string in the request URL:
