PhpStorm not showing node_modules

PhpStorm is hiding the node_modules directory inside the IDE. Since I was stuck like this for a few weeks, I’ll post it here.

Using AWS IAM and S3 for loading config information into node docker containers running on ECS

This article shows how to setup a docker image using node and load your config info for each environment from IAM protected s3. The node base image is stripped down, so there’s a few modifications to the AWS example scripts that need to happen.

Mongoose connection events and reconnecting to MongoDB

I’ve seen many methods to have mongoose reconnect to mongo after an error. This is a huge problem, especially if the network drops for even a second. In our app, mongoose didn’t even know the connection had dropped, and our application would not be able to reach the database. To fix this, we had to force mongoose to reconnect on it’s own.

Bulk updating, inserting, or copying domains into MongoDB using collection.initializeUnorderedBulkOp

Processing large amounts of data in MongoDB and Node.js will probably lock your single threaded application. This is just my reference for when I need to process a large amount of documents using collection.initializeUnorderedBulkOp.

CSS setting the height of a DIV based on a ratio of the width

I had a situation where I needed to set the height of a multiple divs to be the same, but proportionate to its width. The application had gallery like page, which each item’s width based on a percentage of the window width. Each item had an image, with a set aspect ratio and a width set to 100%. In order to get the height to scale with the window width, here’s the CSS trickery I ended up using. Of course there are Javascript methods and other CSS hacks, this was the simplest in my opinion.
