In nodejs, you can use flowing mode and non-flowing mode to read data. When using flowing mode, the operating system's i/o mechanism will be used to read data, which will allow you to read data at the fastest speed. When you use non-flowing mode, you must explicitly call the object's read method to read the data
enter:
An object that implements the readabled interface
fs.readStream、http.incomingMessage、net.Socket、child.stdout、child.stderr、process.stdin、Gzip、Deflate、DeflateRaw
event that will trigger
readable、data、end、close、error
Owned methods and properties
pipe、unpipe、unshift、read、pause、resume、setEncoding
output:
An object that implements the writeabled interface
fs.writestream、process.stdout、process.stdout、child.stdin、net.Socket、http.ClientRequest、http.ServerResesponse、Gunzip、Infalte、InflateRaw
event that will trigger
drain、pipe、unpipe、finish、error
Owned methods and properties
