Delete all non-design docs in CouchDB (using cradle)

couchdb_delete_non_design_docs.js

var cradle = require('cradle');

var database = 'app';

cradle.setup({
    host: '127.0.0.1',
    port: 5984,
    auth: { username: "YOUR_USERNAME", password: "YOUR_PASSWORD" }
});

var db = new(cradle.Connection)().database(database);

/* Delete non-design documents in a database. */
db.all(function(err, doc) {
    /* Loop through all documents. */
    for(var i = 0; i < doc.length; i++) {
        /* Don't delete design documents. */
        if(doc[i].id.indexOf("_design") == -1) {
            db.remove(doc[i].id, doc[i].value.rev, function(err, doc) {
                console.log(doc);
            });
        }
    }
});

nice!

This was crazy helpful in a time of need, thank you!

Using couchDB bulk documentation we could also do this in one go (be ware of conflicts though as with all bulk operations).

db.view( 'design/_all', { include_docs: true }, function (err, res) {

var docs = [];
for(i in res) {
var doc = res[i].doc;
doc._deleted = true;
docs.push(doc);
}

if ( docs.length > 1 ) db.save(docs);
});
