    node.js heroku npm
    I’m so baffled. I tried to push a change to heroku and all of a sudden it won’t update. The change was inside a string. Nothing weird programmy.Something similar happened once before, but I tried again a few minutes later and it just worked. Not so this time.I tried adding an npm engine to my package.json, and I tried adding the node_modules folder, but neither had an effect.Installing dependencies npm http GET https://registry.npmjs.org/querystring npm http GET https://registry.npmjs.org/mongoo

    node.js mongodb backbone.js
    I’m building my first app using the above technologies. I’ve spent the last couple of weeks using Backbone and now I’m trying to build an api using express on node with mongo db.

Not a problem until I try and update the document in mongo. Backbone passes back the _id as a string and it should be a object id. Mongo fails the update beca

The problem I am running into is that, when many of these AJAX calls come in at once, Mongoose fails with a “Document not found” error on some
