This API implements a simple ATM, with balances, deposits, withdrawals and transfers. It benefits from the great swagger-autogen to generate a Swagger OpenAPI documentation on /docs route.
The authentication is done using an unencrypted cookie that stores the e-mail of the user logged in (so, please, don't copy the technique if you're using it as a reference for any productive code), and it also works out-of-the-box in Swagger's Try It Out feature.
If you have NodeJS installed, it is as simple as cloning the repo and running the install command of your preferred JS package manager. For starters, NPM works just fine:
git clone https://github.com/rlawisch/example_api.git atm_api
cd atm_api
npm install
If you don't have a NodeJS installation ready yet, it is recommended to get the LTS version from here, and then running the above commands on your terminal.
The Swagger API specification needs to be generated before the project runs. You can build and then start the project:
npm run build
npm start
Some sort of filesystem watch was not provided to regenerate the specs during development, but the two commands listed above where encapsulated in an npm run dev command for simplicity.
