How to delete a document from collection using NodeJS

Remove multiple documents:

/* Send error to browser */
var errSend_browser = function (err, res) {
  res.send('category_model.js -:' + err);
};

 

//var selector = {id: 1};  //remove only one document

var selector = [{id: 1}, {id: 5}]; //remove two documents

var options = {};

db.collection('collection_name', function (err, collect) {
        if (err) { errSend_browser(err, res); }
        collect.remove(selector, options, function (err, result) {
            if (err) { errSend_browser(err, res); }
            res.redirect('/admin/categories/');
            console.log('\nDeleted records: ' + result); //{"ok":1,"n":2}
        });
 });

 

 

 

Remove one document:

var selector = {id: 1};

db.collection('collection_name').remove(selector, options, function (err, status) {
        if (err) {
          errSend_browser(err, res);
        } else {
          res.redirect('/admin/categories/');
          console.log('\nDeleted records: ' + status); //{"ok":1,"n":1}
        }

       db.close();

});
