Ascend

A Phoenix Liveview explorer for UK and Irish Mountains

Written to explore liveview and consolidate my thinking around contexts.

Data is from the wonderful The Database of British and Irish Hills Well worth reading the database notes.

Setup

To start your Phoenix server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

The data is stored in a csv found in priv/data/dobish.csv, and you can import it locally from a console via: Import.Dobih.import("priv/data/dobih.csv")

Tests can be run via mix test

Deployment

A running example can be found at Ascend on Fly.io.

Presently running within the free allowances of the Fly.io platform.

To run your own instance of ascend, modify the fly.toml file to point to your own setup on Fly.io.

It's using sqlite3, so a volume is highly recommended, 1Gb is ample.

To connect to a running console run: fly ssh console

Then run the following commands: app/bin/ascend remote

The priv folder isn't immediately accessible in production environment as it's in a release. To load the data in production:

1. Scale the app to 1GB memory
2. Connect to the new instance console
3. Run Path.join(Application.app_dir(:ascend, "priv"), "data/dobih.csv") |> Import.Dobih.import
4. Exit and scale down the app to the default 256MB
