wes bank

This is a small demo application for the wes library. Each session can lock a set of bank accounts that make atomic actions to them. So in wes terms a session is a channel and a account is a type of actor. wes bank also exposes the available actions through a http api.

Running

Clone and build this repo:

git clone [email protected]:wooga/wes_bank.git
cd wes_bank

Start the app:

make start

HTTP api

Use httpie to be able to copy paste these example commands.

Create account a1 as user1:

http POST localhost:8080/a1 User-Id:user1 -j

Insert money:

http POST localhost:8080/a1/insert User-Id:user1 amount:=10 -j

Check balance:

http GET localhost:8080/a1/balance User-Id:user1 -j

Transfer money between accounts (a2 needs to be created):

http POST localhost:8080/a1/transfer User-Id:user1 to=a2 amount:=10 -j

http GET localhost:8080/a2/balance User-Id:user1 -j
