Research direction
This issue requests adding PDF417 barcode decoding to QuaggaJS, an existing JavaScript barcode scanner library. To start, review the current decoding pipeline in the source code (e.g., 'src/decoder/') and understand how existing codes like Code128 or EAN are implemented. Investigate PDF417 specification and potential pure JavaScript decoders for reference. No linked PR or maintainer direction is provided, so exploration of the library's architecture and feasibility is needed.
