我如何使用“ stream.pipe（fs.createWriteStream（））”

Question

How do I use stream.pipe?

I'm running a function that outputs:

const fs = require('fs');
const screenshot = require('screenshot-stream');
const stream = screenshot('http://google.com', '1024x768');
stream.pipe(fs.createWriteStream('picture.png'));

My next step is taking that picture (picture.png) and assigning it here:

var content = fs.readFileSync('/path/to/img')

In other words, what is the path to the image so I can upload it?

Answer 1

Lets say, Your project directory name is "PROJECT", And you executed this file from the root directory of your project, Then the PICTURE.png file will be created in the root directory.

And the path to that file'll be __dirname + "/PICTURE.png" if you are still in the root directory of your project.
