GWARR

Golang Webhooks (for) *arr

Description

I was unhappy with the current state of *arr notifications sent to Slack via the inbuilt notifications.

I didn't want to learn how to work on the *arr codebase initially, so I just decided to write a little proxy.

It sits on a host you own, you point your *arr notifications at it, and it makes modern well formatted Slack messages.

Features

• Updates messages for certain state changes (added -> grabbed -> deleted)
• Redis is used as the cache now. (There might be some bugs)
• Emojis :star:
• Links back to your *arr instance
• Adds some (currently very limited) metadata to the message
• Unfurls
• a prom /metrics endpoint

Running

• Create a Slack application here
• Create a token with the chat:write scope
• Install the application to your workspace
• Take note of the token. It should begin with xoxb
• Add the application to the channel of your choosing and note the channel ID
• Add the following variables to your environment:

GWARR_RADARR_URL='<url with proto of radarr instance>'
GWARR_SLACK_CHANNEL_ID='<channel id>'
GWARR_SLACK_BOT_TOKEN='<bot token>'

• Build the binary go build cmd/gwarr/gwarr.go
• Run GWARR ./gwarr

Planned

• Fix golangci-lint errors
• Handle *arr test notifications
• Add some images
• Add other *arrs support
• More testing
• Refine the message types
• Clean up the code
• It works, but it needs some TLC
• More configuration options
• A docker container
• Add version details
• Add Makefile/build stuff
• Add Github Actions
• Improve logging
