pg-mem VS vscode-mocha-hmr-sample

I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.

I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

https://github.com/oguimbal/pg-mem

So I'm not an expert, but for simplistic use cases I merely make use of https://github.com/oguimbal/pg-mem

It's a lot faster and easier than dealing with containers and the like.

In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.

I've created an issue if you wish to track that.

Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]

See documentation ("inspect a table" and "manually insert items" sections)

To get a glimpse of what I'm talking about, you can clone this repo and follow "Development" instructions (by the way this is a small OS lib I maintain, I wrote about it here)

In short, you'll have to setup webpack for your nodejs server, enabling HMR. To do this, I can point you at this sample repo. It demonstrates how to setup a simple Typescript+Express server with Webpack HMR + unit testing (read its instructions before cloning).
