A stream that's ready to be replaced by another
npm install tmp-streamA stream that's ready to be replaced by another.
Create a temporary stream and replace it with the real one after 500ms.
Use the temporary stream immediately, everything gets buffered.
``js
var tmpStream = require('tmp-stream');
var through = require('through');
function createStream () {
var tmp = tmpStream();
setTimeout(function () {
var realStream = through(function (chunk) {
this.queue(chunk.toUpperCase());
});
tmp.replace(realStream);
realStream.write('hey');
}, 500);
return tmp;
}
var stream = createStream();
stream.on('data', console.log);
stream.write('you');
`
outputs:
`bash`
$ node example/simple.js
HEY
YOU
With npm do
`bash``
