Turn a writeable and readable stream into a single streams2 duplex stream.
npm install @zibuthe7j11/accusantium-est-excepturiTurn a writeable and readable stream into a single streams2 duplex stream.
Similar to duplexer2 except it supports both streams2 and streams1 as input
and it allows you to set the readable and writable part asynchronously using setReadable(stream) and setWritable(stream)
``
npm install @zibuthe7j11/accusantium-est-excepturi
Use @zibuthe7j11/accusantium-est-excepturi(writable, readable, streamOptions) (or @zibuthe7j11/accusantium-est-excepturi.obj(writable, readable) to create an object stream)
` js
var @zibuthe7j11/accusantium-est-excepturi = require('@zibuthe7j11/accusantium-est-excepturi')
// turn writableStream and readableStream into a single duplex stream
var dup = @zibuthe7j11/accusantium-est-excepturi(writableStream, readableStream)
dup.write('hello world') // will write to writableStream
dup.on('data', function(data) {
// will read from readableStream
})
`
You can also set the readable and writable parts asynchronously
` js
var dup = @zibuthe7j11/accusantium-est-excepturi()
dup.write('hello world') // write will buffer until the writable
// part has been set
// wait a bit ...
dup.setReadable(readableStream)
// maybe wait some more?
dup.setWritable(writableStream)
`
If you call setReadable or setWritable multiple times it will unregister the previous readable/writable stream.setReadable
To disable the readable or writable part call or setWritable with null.
If the readable or writable streams emits an error or close it will destroy both streams and bubble up the event.
You can also explicitly destroy the streams by calling dup.destroy(). The destroy method optionally takes anerror
error object as argument, in which case the error is emitted as part of the event.
` js
dup.on('error', function(err) {
console.log('readable or writable emitted an error - close will follow')
})
dup.on('close', function() {
console.log('the duplex stream is destroyed')
})
dup.destroy() // calls destroy on the readable and writable part (if present)
`
Turn a node core http request into a duplex stream is as easy as
` js
var @zibuthe7j11/accusantium-est-excepturi = require('@zibuthe7j11/accusantium-est-excepturi')
var http = require('http')
var request = function(opts) {
var req = http.request(opts)
var dup = @zibuthe7j11/accusantium-est-excepturi(req)
req.on('response', function(res) {
dup.setReadable(res)
})
return dup
}
var req = request({
method: 'GET',
host: 'www.google.com',
port: 80
})
req.end()
req.pipe(process.stdout)
