# Event Sourced Counter
Trying out [Event Sourcing] design
## Design
## Run
```sh
# run an instance of Event Store in the background
docker run --detach --name esc-eventstore --publish 2113:2113 --publish 1113:1113 eventstore/eventstore
# run an instance of Mongo in the background
docker run --detach --name esc-mongo --publish 27017:27017 mongo
# docker rm -fv esc-eventstore esc-mongo
```
```sh
# run the web API
cd ./EventSourcedCounter/
dotnet run
```
```sh
# start a new counter "foo"
curl -X POST --data '' "http://localhost:5005/api/counters/foo"
# get value for counter "foo"
curl -X GET "http://localhost:5005/api/counters/foo"
# increment it by 1 and then by 3
curl -X PATCH "http://localhost:5005/api/counters/foo"
curl -X PATCH "http://localhost:5005/api/counters/foo?count=3"
# get value for counter "foo" again
curl -X GET "http://localhost:5005/api/counters/foo"
```
```sh
# run services
docker start esc-eventstore esc-mongo
```
```sh
# create 100 counters
for i in {1..100}
do
curl -X POST --data '' "http://localhost:5005/api/counters/foo$i"
done
```
```sh
docker run --detach --name esc-couchdb --publish 5984:5984 -d couchdb
```
