I want the user to be able to download a file while it is uploading. So I
write this code to test.
var fs = require('fs');
> var writeStream = fs.createWriteStream(__dirname + "/uploading.txt");
> writeStream.on('open', function(){
> console.log('Write stream has open');
> //Write a number every 1 second.
> var i = 1;
> var repeat = function(){
> writeStream.write(i);
> console.log('Number ' + i + ' has been write to the file');
> i = i + 1;
> setTimeout(repeat, 1000);
> };
> repeat();
> var readStream = fs.ReadStream(__dirname + "/uploading.txt");
> readStream.on('data', function(data){
> console.log('Data is coming: ' + data);
> });
> readStream.on('end', function(){
> console.log('Stream END');
> });
> });
But the result is like this
Write stream has open
> Number 1 has been write to the file
> Data is coming: 1
> Stream END
> Number 2 has been write to the file
> Number 3 has been write to the file
> Number 4 has been write to the file
When the reading speed is faster than the writing speed, I will receive a
'end' signal, rather than paused.
So how to deal with this problem?
