Options
So changes-stream
can take a fair bit of options in order so that you can
fully customize your _changes
request. They include the following:
db: 'http://localhost:5984/my_db' // full database URL feed: 'continuous' // Can also be longpoll technically but not currently implemented filter: 'docs/whatever' // Can be a defined couchdb view, a local filter function or an array of IDs inactivity_ms: 60 * 60 * 1000 // time allow inactivity before retrying request timeout: undefined // How long couchdb should wait for a change to show up before closing the feed. in milliseconds requestTimeout: 2 * 60 * 1000 // http timeout agent: undefined // http agent since: 0 // update sequence to start from, 'now' will start it from latest heartbeat: 30 * 1000 // how often we want couchdb to send us a heartbeat message style: 'main_only' // specifies how many revisions returned all_docs would return leaf revs include_docs: false // whether or not we want to return the full document as a property query_params: {} // custom arbitrary params to send in request e.g. { hello: 'world' } use_post: false // switch the default HTTP method to POST (cannot be used with a filter array)
Example
