Tweetyodel

Just another twitter experiment

What is Tweetyodel?

It is a GenServer that can search or stream the Twitter API. Think about it like one process per Twitter query/topic, ideal to easily integrate with Phoenix channels or other applications.

NOTE: It's a pet project, however if you would like to give it a try, why not!

Configuration

Export these environment variables (you have to create your twitter app first on https://apps.twitter.com/)

export TWITTER_CONSUMER_KEY="0123456789"
export TWITTER_CONSUMER_SECRET="0123456789"
export TWITTER_ACCESS_TOKEN="0123456789"
export TWITTER_ACCESS_SECRET="0123456789"

You have also the possibility to configure:

config :tweetyodel,
  max_keep_tweets: 100,
  purge_interval: 30_000

:max_keep_tweets is the number of maximum tweets that you want to keep in your GenServer process after the purge operation

:purge_interval is the number of milliseconds that you want to wait to purge the tweets. They will be reset to :max_keep_tweets after this interval periodically.

How to use

Tweetyodel.Worker.Supervisor.start_tweet("ma' namespace")

If you want to use the Twitter Streaming API, follow these steps:

# Bieber has always tweets
Tweetyodel.Worker.start_stream("ma' namespace", "bieber")
# Fetch only the the first 5 tweets and their text
# NOTE that pulling data from twitter starts after 10 seconds
Enum.map(Tweetyodel.Worker.entries("ma' namespace"), fn tweet -> tweet.text end) |> Enum.take(5)

If you want your twitter stream to start to pull tweets instantly:

Tweetyodel.Worker.start_stream("ma' namespace", "linux", 0)

If you want to search instantly Twitter:

Tweetyodel.Worker.search("ma' namespace", "#myelixirstatus")

You can also stop the stream (which will stop and kill the streaming process) However it will keep the tweets searched or streamed

Tweetyodel.Worker.stop_stream("ma' namespace")

NOTE also that a purge cleanup happens every minute which purges the tweets to the last 100

Installation

If available in Hex, the package can be installed as:

1. Add tweetyodel to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:tweetyodel, "~> 0.1.0"}]
end
```

2. Ensure tweetyodel is started before your application:

```elixir
def application do
  [applications: [:tweetyodel]]
end
```
