Papa Parse for Node
Papa Parse can parse a Readable Stream instead of a File when used in Node.js environments (in addition to plain strings). In this mode,
encodingmust, if specified, be a Node-supported character encoding. The
workerconfig options are unavailable.
Papa Parse can also parse in a node streaming style which makes
.pipeavailable. Simply pipe the Readable Stream to the stream returned from
Papa.parse(Papa.NODE_STREAM_INPUT, options). The
completeconfig options are unavailable. To register a callback with the stream to process data, use the
dataevent like so:
stream.on('data', callback)and to signal the end of stream, use the 'end' event like so:
Papa Parse is under test. Download this repository, run
npm install, then
