Jennifer + Kemal sample application

This is a project presenting efficient integration of Jennifer ORM and Kemal web framework.

This project is inspired by Ruby on Rails Tutorial sample application.

Getting Started

To get started with the app, clone the repo and then install the needed dependencies:

$ cd /path/to/repos
$ git clone git@github.com:imdrasil/spider-gazelle_jennifer_sample_app.git
$ cd spider-gazelle_jennifer_sample_app
$ shards
$ make setup

The last command copies ./config/database.yml.example to ./config/database.yml. All database parameters are located in ./config/database.yml - complete them with your own values.

Next do the database setup.

$ make sam db:setup

This will automatically create development database, run all migrations and populate seeds.

To start a dev server run in a separate console tabs next commands:

$ make server
$ make webpack

NOTES

Proposed controller-based architecture for a Kemal application is just a one of possible solutions and shouldn't be considered as best practice.
