javascript - Couchdb's Update Event Handler in Node.js -

i want create app in node.js. app modified document, lets :

{_id: xxx, text: "hello"}

every time document changed, want execute function in node.js app. it's

$db.on('update', function(id){ console.log("there changes in " + id) })

how can node.js ?

you looking couchdb's changes feed. every time document updated in db, have subscribed to, notification sent. can hear on notification , execute code.

you can subscribe particular document id's. see request options in post request.

also since using node js suggest take @ follow library. makes want lot easier.

example:-

var follow = require('follow'); follow({db: "<database name here>", include_docs:true}, function(error, change) { if(!error) { console.log(change.doc) // updated doc console.log("got alter number " + change.seq + ": " + change.id); } });
