Usage

var db = new PouchDB('mydb')

db.liveQuery('my/view')
  .then(function(result) {
    // result is extended view query result
    // { total_rows: 3, rows: [{ id: 'mydoc', key: ... }, ...] }
    
    // event emitter
    result.on('change', function(change) {
      // result has been updated
    })

    // stop listening
    result.cance()
  })

db.liveQuery(fun, [options])

Similar to db.query.

Options

• fun: The name of a view in an existing design document, e.g. 'mydesigndoc/myview'.
• options.include_docs: Include the document in each row in the doc field.
• options.descending: Reverse the order of the output rows.
• options.startkey and options.endkey: Return only rows between these.

Whats Missing

• callback - Currently works only with promises.
• options.key - Key exact match is ignored on view update.
• options.reduce - No reduce support at all. Just to mention some...
