How to store the data into a file for a jpeg that has been fetched successfully in nodejs ?

Answer 1

<DD> ty for your response, Don't know what data it is . But i am using fetch to get the image ,now i want to store whatever image data(in bytes or any other format) fetch function send us, in a jpeg file .

Fyi , it is not about sending to a client or anyone else . I could download the file through browser but just want to see how it can be done using node js.

Answer 2

<DD> my code is a mess ,anyway i tried writing something by following this link and going through other articles ,but didn't understand how to do it.

https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream/pipeTo

The above article explains how to use "pipeto" to direct readableStream to writeableStream but i am unable to create writeableStream .

Though ,I coded a simple writestream but it didn't work out .

let writeStream = fs.createWriteStream("something.jpeg"
);

Error : TypeError [ERR_INVALID_ARG_TYPE]: The "transform.writable" property must be an instance of WritableStream. Received an instance of WriteStream.
