| // 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. | |

| // | |
| // 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. | |

I think you might be counting some node core modules against the size but I'm not sure really. If an npm module is reliable and passes its unit tests I generally don't worry how many bytes it is.

Interesting. Looks like the dependencies of htmlparser2 are pretty big in terms of lines of code. Why does this concern you per se though? Are you hoping to use it browser side? It's not as if you can trust a browser to sanitize anything anyway.
