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:
Papa Parse is under test. Download this repository, run
npm install, then
npm test to run the tests.
To discuss a new feature or ask a question, open an issue. To fix a bug, submit a pull request to be credited with the contributors! Remember, a pull request, with test, is best. You may also discuss on Twitter with #PapaParse or directly to me, @mholt6.
If you contribute a patch, ensure the tests suite is running correctly. We run continuous integration on each pull request and will not accept a patch that breaks the tests.
