Barcode-Parsing

this package has a fairly narrow scope and is used in conjunction with an Ionic project to read values provided by a physical wedge scanner and parse out the values. I am working on wrapping up the scanning angular component that consumes this directly.

Usage

    const barcodeParser = new BarcodeParser({
        readers: [
            Symbologies.Code39,
            Symbologies.ITF8,
            Symbologies.GTINX
        ],
        readerConfigurations: []
    });

    barcodeParser.parse(']I010734074010258');
    barcodeParser.parse(']C100111111111111111111101234 30100 310600100');
    barcodeParser.parse(']Z00000000');

** please note the input above with spaces would never be valid from a scanner, the spaces would instead be an invisible group seperator. This library replaces the GS character with a space before parsing so it works for both illustrative purposes and testing.

Roadmap

• This package as it stands is very much a "good enough" for what we needed it for but it needs a little work before it can be used easily in an arbitrary project.
• Reader Specific Configurations. See Code39.
