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,
encoding must, if specified, be a Node-supported character encoding. The
worker config options are unavailable.
Papa Parse can also parse in a node streaming style which makes
.pipe available. Simply pipe the Readable Stream to the stream returned from
Papa.parse(Papa.NODE_STREAM_INPUT, options). The
complete config options are unavailable. To register a callback with the stream to process data, use the
data event like so:
stream.on('data', callback) and to signal the end of stream, use the 'end' event like so:
For usage instructions, see the homepage and, for more detail, the documentation.
Papa Parse is under test. Download this repository, run
npm install, then
npm test to run the tests.
