Fetch - Reading Stream

fetch-stream.js

import ndjsonStream from 'can-ndjson-stream';

const getStream = async () => {
  
  try {
      const response = await fetch(url);
      const reader = ndjsonStream(response.body).getReader();

      let reader;
      while (!result || !result.done) {
        const data = result.value;
        processLine(data) // Do things with line.
      }
  
  } catch (err) {
        handleError(err)
  }
}
