> **Warning**: Digest is a work in progress.

Here at D3 Estudio, Slack is our primary communication channel. Found a nice article? Slack. Found a cool gif? Slack. Want to spread the word about an event? Well, guess what? Slack.

We have been overusing the (relatively) new Reactions feature lately, and we stumbled on a nice idea: Why not create a digest based on these reactions?

Well, this is what Digest does: it watches channels through a bot and stores messages and their respective reactions.

Installing

Digest is distributed through a single Docker Image containing all required binaries:

$ docker pull d3estudio/digest:latest

In order to work, Digest needs a Mongo and Redis instance to connect to. Those servers addresses can be defined in the environment variables of the containers running each process:

• DIGEST_TOKEN: Slack token used to authenticate and connect to your Slack team. This token can be obtained by Creating a New Slack Bot.
• DIGEST_SILENCER_EMOJIS: A comma-separated string of reactions that will prevent a given message that contains it from appearing publicly. Please do note that this does not prevent a message from being stored. Defaults to no_entry_sign.
• DIGEST_REDIS_SERVER: Address of the Redis server used for IPC. Defaults to redis.
• DIGEST_REDIS_PORT: Port of the Redis server used for IPC. Defaults to 6379.
• DIGEST_MONGO_SERVER: URL of the Mongo server used for storing data and keeping indexes. It must be in following format [mongodb://][user:pass@]host1[:port1][,host2[:port2],...][/database][?options], which allows it from being simple as localhost to something more involved, like mongodb://myuser:mypass@localhost:40001,otherhost:40001/mydb. Assumes 27017 as the default port, if not provided. Defaults to mongo.
• DIGEST_MONGO_DATABASE: Name of the database that will hold collections created by the application. Defaults to digest.
• DIGEST_BASE_QUEUE_NAME: Name of the base name of all Redis queues. Useful if working with more than one instance on the same Redis server. Defaults to Digest.
• DIGEST_TWITTER_KEY and DIGEST_TWITTER_SECRET: Used by the prefetcher process to acquire oembed data from Twitter. Those keys are optional, but not providing them will prevent Digest from embeding tweets into the results. Defaults to "".

Developing

The development environment only requires a functional installation of the Go compiler and Godep, that is used to manage our dependencies. That said, everything you have to do is clone this repository into your $GOPATH, head over to it and run godep restore. This repository also contains a basic docker-compose.yml that will spin up a Redis and Mongo instance.
