# PredictionAnalyzer
An app for aggregating and analyzing the accuracy of GTFS predictions using
TripUpdates and VehiclePositions over time.
## Prerequisites
* PostgreSQL 10+
* [`asdf`](https://asdf-vm.com/#/core-manage-asdf)
* [`direnv`](https://github.com/direnv/direnv/blob/master/docs/installation.md)
_(recommended)_
PostgreSQL and Direnv are available on macOS Homebrew.
## Setup
1. `asdf install`
2. `cp .envrc.template .envrc`
* You may have to adjust `DATABASE_ROOT_URL` in this file to reflect your
Postgres install, e.g. changing `postgres@` to `your_username@`
3. `direnv allow`
4. `mix deps.get`
5. `mix ecto.setup`
6. `npm install --prefix assets`
If you have previously set up the DB and run into issues, you may have to drop the DB and run `mix ecto.setup` to recreate it.
## Common Tasks
* Run the app: `mix phx.server` (then go to )
* Run the tests: `mix test`
