Creating a Phoenix Framework Application with SQLite

Phoenix defaults to using Postgres, which is probably very sensible. Getting SQLite up and running using Sqlite.Ecto, though, is reasonably easy.

First, add the dependency for sqlite_ecto in mix.exs:

defp deps do
{:sqlite_ecto, "~> 1.0.0"},

Now update your config/dev.exs to include reference Sqlite.Ecto:

config :widgetapp, Widgetapp.Repo,
adapter: Sqlite.Ecto,
database: "path/to/widgetapp.sqlite"

Drop into your console and run mix deps.get to pull in your new dependencies and then run mix ecto.create to get your database set up. If all goes well, you should get a new file created as specified in your dev.exs as above.

From here, just develop as normal.
