Flashfeed (Elixir version)

Local radio and video news feed for Amazon (and friends, eventually), build with Elixir.

Exercises:

• Elixir language
• Phoenix Framework as API server and CORS proxy
• Phenix LiveView for UI with live search and media playback
• Pow for user authentication, integrated with LiveView, REST API and GraphQL API
• Absinthe for GraphQL
• Floki HTML parser for web scraping
• News feed generation for Amazon Alexa
• Docker with Multi-stage build
• Phoenix Swagger for API documentation

Local Build

mix deps.get
mix phx.swagger.generate

Note: when LiveView version is updated we need to update the assets as well

cd assets && npm install phoenix_live_view --force

Local Docker Build

docker build -t flashfeed-elixir:latest .

Local Start

Elixir

mix run --no-halt

Docker

Needs network and user access to a Postgres DB.

export FLASHFEED_DB_DATABASE="flashfeed"
export FLASHFEED_DB_USERNAME="postgres"
export FLASHFEED_DB_PASSWORD="postgres"
export FLASHFEED_DB_HOSTNAME="database"
export FLASHFEED_DB_PORT="5432"

export FLASHFEED_HOST_FOLDER_MNESIA="$(pwd)/tmp/docker/mnesia"

mkdir -p $FLASHFEED_HOST_FOLDER_MNESIA

docker stop flashfeed-elixir

docker run -e FLASHFEED_DB_DATABASE \
-e FLASHFEED_DB_USERNAME \
-e FLASHFEED_DB_PASSWORD \
-e FLASHFEED_DB_HOSTNAME \
-e FLASHFEED_DB_PORT \
--volume ${FLASHFEED_HOST_FOLDER_MNESIA}:/mnt/mnesia \
--name flashfeed-elixir \
--rm \
-p 41384:41384 \
-t flashfeed-elixir:latest
