// a transform stream is a readable/writable stream where you do
|
||
// something with the data. Sometimes it's called a "filter",
|
||
// but that's not a great name for it, since that implies a thing where
|
||
// some bits pass through, and others are simply ignored. (That would
|
||
// be a valid example of a transform, of course.)
|
||
//
|
||
// While the output is causally related to the input, it's not a
|
||
// necessarily symmetric or synchronous transformation. For example,
|
||
// a zlib stream might take multiple plain-text writes(), and then
|
||
// emit a single compressed chunk some time in the future.
|
||
//
|
||
// Here's how this works:
|
||
//
|
||
// The Transform stream has all the aspects of the readable and writable
|
||
// stream classes. When you write(chunk), that calls _write(chunk,cb)
|
||
// internally, and returns false if there's a lot of pending writes
|
||
// buffered up. When you call read(), that calls _read(n) until
|
||
// there's enough pending readable data buffered up.
|
||
//
|
||
// In a transform stream, the written data is placed in a buffer. When
|
||
// _read(n) is called, it transforms the queued up data, calling the
|
||
// buffered _write cb's as it consumes chunks. If consuming a single
|
||
// written chunk would result in multiple output chunks, then the first
|
||
// outputted bit calls the readcb, and subsequent chunks just go into
|
||
// the read buffer, and will cause it to emit 'readable' if necessary.
|
||
//
|
||
// This way, back-pressure is actually determined by the reading side,
|
||
// since _read has to be called to start processing a new chunk. However,
|
||
// a pathological inflate type of transform can cause excessive buffering
|
||
// here. For example, imagine a stream where every byte of input is
|
||
// interpreted as an integer from 0-255, and then results in that many
|
||
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
|
||
// 1kb of data being output. In this case, you could write a very small
|
||
// amount of input, and end up with a very large amount of output. In
|
||
// such a pathological inflating mechanism, there'd be no way to tell
|
||
// the system to stop doing the transform. A single 4MB write could
|
||
// cause the system to run out of memory.
|
||
//
|
||
// However, even in such a pathological case, only a single written chunk
|
||
// would be consumed, and then the rest would wait (un-transformed) until
|
||
// the results of the previous transformed chunk were consumed.

CSV-JS - A Comma-Separated Values parser for JS
|
||
|

Built to rfc4180 standard, with options for adjusting strictness:
|
||
- optional carriage returns for non-microsoft sources
|
||
- automatically type-cast numeric an boolean values
|
||
- relaxed mode which: ignores blank lines, ignores gargabe following quoted tokens, does not enforce a consistent record length
