TypeError: Readable.from is not a function

[ilivestrong]

Hi Folks,

I was learning "Streams" from Nodejs.org website. I would like to bring to your notice that one of the API i.e., Readable.from is throwing an error - "TypeError: Readable.from is not a function".

I am using Node v11.13.0

In debug mode, I found that there isn't any property accessor named - "from" on "Readable" class, it's prototype or on it's super class either(Stream).

FYI, I didn't make any tweaks to the provided example, and tried to use it as it is(screenshot attached).

If I am missing anything, please enlighten me.

Thanks in advance,
Deepak

Thanks for opening an issue! Adding version metadata to the documentation was missed in #27660, it’s only been available since Node.js 12.3.0. (Node.js 11.x is unsupported at this point, by the way.)

@addaleax Thank you for the prompt response, will upgrade my Node.

Cheers!

Is still showing in the v10.x documentation:

same here, node v20

// A generator that will yield positive integers
async function* integers() {
    let i = 1;
    while (true) {
        console.log(`yielding ${i}`);
        yield i++;

        await sleep(100);
    }
}

// Collect data from stream
async function run() {
    const stream = ReadableStream.from(integers());
