I’ve set up a local CouchDB database and I’d like to replicate it to a PouchDB database, using JavaScript in a web page running on localhost.<\/p>\n

With the code below I get this error:<\/p>\n

\n

Origin http:\/\/localhost<\/code> is not allowed by Access-Control-Allow-Origin.<\/p>\n<\/blockquote>\n

With http:\/\/<\/code> removed from REMOTE, I don’t get an error, but no docs are shown as replicated.<\/p>\n

Looking at IndexedDB databases from Chrome DevTools, I can see the database has been created (but doesn’t appear to have documents).<\/p>\n

Running in Chrome 29.0.1535.2 canary.<\/p>\n

Can I do this locally, or do I need to set up a remote CouchDB database and enable CORS (as per the CouchDB docs)?<\/p>\n

var REMOTE = 'http:\/\/127.0.0.1:5984\/foo';\nvar LOCAL = 'idb:\/\/foo';\n\nPouch(LOCAL, function(error, pouchdb){\n  if (error) {\n    console.log(\"Error: \", error);\n  } else {\n    var db = pouchdb;\n    Pouch.replicate(REMOTE, LOCAL, function (error, changes) {\n      if (error) {\n        console.log('Error: ', error);\n      }\n      else {\n        console.log('Changes: ', changes);\n        db.allDocs({include_docs: true}, function(error, docs) {\n          console.log('Rows: ', docs.rows);\n        });\n    }});\n  }\n});\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
