Is is possible to use 2 or more streams at once?

[benderlidze]

Here is an example. I am getting messed data with this script. Some part on data from ndjson1.json is in mainD2 and vice versa. Is this a bug or it is impossible to use 2 or more streams at once?

<script src='https://unpkg.com/[email protected]/dist/global/can-ndjson-stream.js'></script>

<script>
    const streamerr = e => {
        console.warn("Stream error");
        console.warn(e);
    }

    const mainD1 = [];
    const mainD2 = [];

    fetch("ndjson1.json").then((response) => {
        return can.ndjsonStream(response.body);
    }).then(todosStream => {
        var reader = todosStream.getReader();

        reader.read().then(read = result => {
            if (result.done) {
                console.log("Done.");
                return;
            }
            
            mainD1.push(result.value);

            reader.read().then(read, streamerr);
        }, streamerr);
    });

    fetch("ndjson2.json").then((response) => {
        return can.ndjsonStream(response.body);
    }).then(todosStream => {
        var reader = todosStream.getReader();

        reader.read().then(read = result => {
            if (result.done) {
                console.log("Done.");
               
                return;
            }

            
            mainD2.push(result.value);

            reader.read().then(read, streamerr);
        }, streamerr);
    });


</script>
