Loading

We pull data from Reddit/Twitter API, transform them using python and load them into a database.

1. Python3
2. sqlite3 (comes preinstalled on most os)
3. Reddit app. You'll need your reddit apps REDDIT_CLIENT_ID, REDDIT_CLIENT_SECRET, & REDDIT_USER_AGENT.
4. Twitter API token, you'll need your twitter APIs BEARER_TOKEN.
5. git

git clone https://github.com/josephmachado/socialetl.git
cd socialetl

Setup

Create a .env in the project's root directory, with the following content

REDDIT_CLIENT_ID=replace-with-your-reddit-client-id
REDDIT_CLIENT_SECRET=replace-with-your-reddit-client-secret
REDDIT_USER_AGENT=replace-with-your-reddit-user-agent
BEARER_TOKEN=replace-with-your-twitter-bearer-token

Run the following commands are to be run via the terminal, from your project root directory.

python3 -m venv venv # Create a venv
. venv/bin/activate # activate venv
pip install -r requirements.txt # install requirements
make ci # Run tests, check linting, & format code
make reset-db # Creates DB schemas
make reddit-etl # ETL reddit data
make twitter-elt # ETL twitter data
make db # open the db to check ELT-ed data 

select source, count(*) from social_posts group by 1;
.exit

Set up git hooks. Create a pre-commit file, as shown below.

echo -e '
#!/bin/sh
make ci
' > .git/hooks/pre-commit
chmod ug+x .git/hooks/*

Make commands

We have some make commands to make things run better, please refer to the Makefile to see them.
