Rough Notes about CQRS and ES

Once upon a time…

I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).

I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).

It seems inevitable to throw Domain Driven Design (DDD) in to the mix.

Read Me

In order to access a server hosted within a vm (guest), for development purposes from the host OS, which is restricted to same origin / localhost only requests, I set up a siple nginx reverse proxy to forward my requests.

Steps

1. To install in a Windows VM, download and install nginx from the current, stable release; I installed to C:\nginx\
2. Edit the <install path>/conf/nginx.conf file with the marked changes in the file of the same name in this gist.
3. Start the nginx executable, located in your install path. There are service wrappers for Windows, or you can just kill the process to stop the nginx instance.
