How to pipe to a file (NodeJS)

rated 0 times [ 71] [ 2] / answers: 1 / hits: 21892 / 8 Years ago, tue, march 1, 2016, 12:00:00

I have created some image data which I've obtained from pixels. Anyway, now I would like to write a file using save-pixels, but the docs only give

var savePixels = require(save-pixels)

...

savePixels(pixels, png).pipe(process.stdout)

How to rewrite this such that it writes it to a file with a specific name ?

Use the file system module included with node. Something like this:

var fs = require(fs);

var savePixels = require(save-pixels);

var myFile = fs.createWriteStream(myOutput.txt);

...

savePixels(pixels, png).pipe(myFile);
