var through = require('through2');
var stream = through(write, end);

var tr =function write(buffer,encoding, next) {
    this.push(buffer.toString().toUpperCase()); 
    next();
}
process.stdin.pipe(through(tr)).pipe(process.stdout);

I am getting error

var stream = through(write, end);
                     ^

ReferenceError: write is not defined at Object.

It is exactly what it says, looks like thevariable write is not defined. – rrk
Move that line after the function definition. – rrk
function end (done) { done(); } after process statement i have one more function end. – gowthami
stream must have two functions write and end that are combined using through – gowthami

Just remove this line;

var stream = through(write, end);
