[GitHub] [couchdb-nano] andywillis opened a new issue, #298: `changesReader` doesn't batch

[GitBox <gi...@apache.org>]

andywillis opened a new issue, #298:
URL: https://github.com/apache/couchdb-nano/issues/298

   <!--- Provide a general summary of the issue in the Title above -->
   
   ## Expected Behavior
   
   I would expect the following to batch new additions to the messages database every 10 seconds. So if I updated the DB 5 times within that 10 second timeout I would expect to see: "a batch of 5 changes has arrived"
   
   ```
     messages.changesReader
       .start({ timeout: 10000 })
       .on('batch', (batch) => {
         console.log('a batch of', batch.length, 'changes has arrived');
       }).on('error', (e) => {
         console.error('error', e);
       });
   ```
   
   ## Current Behavior
   
   What is happening is that no batching is taking place, and every time I update the database I _immediately_ get the log "a batch of 1 changes has arrived".
   
   ## Context
   
   Eventually I want to set up a websocket on the front-end to use that batched data, but I need to figure this part out first. I may just have misunderstood how batching works. Any pointers to help resolve this would be great.
   
   ## Your Environment
   
   * Node v16.5
   * npm 8.5.5
   * Windows 10
