+# combined-stream
+
+A stream that emits multiple other streams one after another.
+
+**NB** Currently `combined-stream` works with streams version 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`.
+
+- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
+
+- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
+
+## Installation
+
+``` bash
+npm install combined-stream
+```
+
+## Usage
+
+Here is a simple example that shows how you can use combined-stream to combine
+two files into one:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+While the example above works great, it will pause all source streams until
+they are needed. If you don't want that to happen, you can set `pauseStreams`
+to `false`:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create({pauseStreams: false});
+combinedStream.append(fs.createReadStream('file1.txt'));
+combinedStream.append(fs.createReadStream('file2.txt'));
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+However, what if you don't have all the source streams yet, or you don't want
+to allocate the resources (file descriptors, memory, etc.) for them right away?
+Well, in that case you can simply provide a callback that supplies the stream
+by calling a `next()` function:
+
+``` javascript
+var CombinedStream = require('combined-stream');
+var fs = require('fs');
+
+var combinedStream = CombinedStream.create();
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file1.txt'));
+});
+combinedStream.append(function(next) {
+  next(fs.createReadStream('file2.txt'));
+});
+
+combinedStream.pipe(fs.createWriteStream('combined.txt'));
+```
+
+## API
+
+### CombinedStream.create([options])
+
+Returns a new combined stream object. Available options are:
+
+* `maxDataSize`
+* `pauseStreams`
+
+The effect of those options is described below.
+
+### combinedStream.pauseStreams = `true`
+
+Whether to apply back pressure to the underlaying streams. If set to `false`,
+the underlaying streams will never be paused. If set to `true`, the
+underlaying streams will be paused right after being appended, as well as when
+`delayedStream.pipe()` wants to throttle.
+
+### combinedStream.maxDataSize = `2 * 1024 * 1024`
+
+The maximum amount of bytes (or characters) to buffer for all source streams.
+If this value is exceeded, `combinedStream` emits an `'error'` event.
+
+### combinedStream.dataSize = `0`
+
+The amount of bytes (or characters) currently buffered by `combinedStream`.
+
+### combinedStream.append(stream)
+
+Appends the given `stream` to the combinedStream object. If `pauseStreams` is
+set to `true, this stream will also be paused right away.
+
+`streams` can also be a function that takes one parameter called `next`. `next`
+is a function that must be invoked in order to provide the `next` stream, see
+example above.
+
+Regardless of how the `stream` is appended, combined-stream always attaches an
+`'error'` listener to it, so you don't have to do that manually.
+
+Special case: `stream` can also be a String or Buffer.
+
+### combinedStream.write(data)
+
+You should not call this, `combinedStream` takes care of piping the appended
+streams into itself for you.
+
+### combinedStream.resume()
+
+Causes `combinedStream` to start drain the streams it manages. The function is
+idempotent, and also emits a `'resume'` event each time which usually goes to
+the stream that is currently being drained.
+
+### combinedStream.pause();
+
+If `combinedStream.pauseStreams` is set to `false`, this does nothing.
+Otherwise a `'pause'` event is emitted, this goes to the stream that is
+currently being drained, so you can use it to apply back pressure.
+
+### combinedStream.end();
+
+Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
+all streams from the queue.
+
+### combinedStream.destroy();
+
+Same as `combinedStream.end()`, except it emits a `'close'` event instead of
+`'end'`.
