twclient

This package provides a high-level command-line client for the Twitter API, with a focus on loading data into a database for analysis or bulk use.

Documentation: mit-ccc.github.io/twclient

Why use this project?

This project offers high-level primitives for researchers who want to get data out of Twitter, without worrying about the API details. The client can handle multiple sets of API credentials seamlessly, helping avoid rate limit issues. [1] There's also support for exporting bulk datasets from the fetched raw data.

Installation

Install the package from pypi:

pip3 install twclient

or, if you want to use the development version, clone this repo and install:

git clone [email protected]:mit-ccc/twclient.git && cd twclient
pip3 install .

You can also use the -e flag to install in editable mode:

pip3 install -e .

To install all development dependencies, replace . with .[dev] in the arguments to pip3 install.

Usage

First, you need to tell twclient about your database backend and Twitter credentials. On the database side, we've only tested with Postgres and SQLite. While the package may well work with other DB engines, be aware that you may encounter issues.

Setup: Database

The database backend can be either sqlite or an arbitrary database specified by a sqlalchemy connection string.

You can set up the database in one of two ways. Both create a persistent profile in your .twclientrc file (or whatever other file you specify), so there's no need to type the database details repeatedly.

First, you can specify the DB with a sqlalchemy connection URL:

# Postgres -- this becomes the default DB because you've created it first
twclient config add-db -u "postgresql+psycopg2://username@hostname:5432/dbname" my_postgres_db

# Or you could use SQLite
twclient config add-db -u "sqlite:///home/user/twitter.db" my_sqlite_db

There's also support for using SQLite without having to think about sqlalchemy and connection URLs:

twclient config add-db -f ./twitter2.db my_sqlite_db2

If you specify a file-backed sqlite DB, as in the examples above, it'll be created if it doesn't exist. Other databases (Postgres, for example) will need to be set up separately.

Finally, you have to install our database schema into your database to receive Twitter data:

# You have to specify the -y to say you're aware all data will be dropped
twclient initialize -d my_postgres_db -y

Be aware that doing this will DROP ALL EXISTING TWCLIENT DATA!!! (Or other tables with the same names.) If you're not just getting started, check to make sure you're using a new or empty database, don't care about the contents, and/or have backups before running this.

Setup: Twitter

You'll also need to set up your Twitter API credentials. [1] As with the database setup, doing this stores the credentials in a config file (the same config file as for database info) for ease of use. Only two sets of credentials are shown, but you can add as many as you want.

Here's an example of adding two API keys:

twclient config add-api -n twitter1 \
    --consumer-key XXXXX \
    --consumer-secret XXXXXX \
    --token XXXXXX \
    --token-secret XXXXXX

twclient config add-api -n twitter2 \
    --consumer-key XXXXX \
    --consumer-secret XXXXXX \
    --token XXXXXX \
    --token-secret XXXXXX

Here's an example of adding credentials that use app-only auth:

twclient config add-api -n twitter3 \
    --consumer-key XXXXX \
    --consumer-secret XXXXXX

Pulling data

To actually pull data, use the twclient fetch command. We'll pull information about three specific users and a Twitter list here. Note that you can refer to lists either by their "slug" (username/listname) or by the ID at the end of a URL of the form https://twitter.com/i/lists/53603015.

First, let's load some users and their basic info:

# you could instead also end this with "-l 53603015"; it's the same list
twclient fetch users -n wwbrannon CCCatMIT MIT -l MIT/peers1

Now, to save typing, let's use the twclient tag command to apply a tag we can use to keep track of these users later:

twclient tag create subjects
twclient tag apply subjects -n wwbrannon CCCatMIT MIT -l MIT/peers1

We can now use this tag in specifying users, such as which users we'd like to fetch tweets for:

twclient fetch tweets -g subjects

And if we also want their follow-graph info (note that a "friend" is Twitter's term for a follow-ee, an account you follow):

twclient fetch friends -g subjects
twclient fetch followers -g subjects

At this point, the loaded data is in the database configured with config add-db. Useful features have been normalized out to save processing time. The raw API responses are also saved for later analysis.

Exporting data

You can query the data with the usual database tools (psql for postgres, sqlite3 for sqlite, ODBC clients, etc.) or export certain pre-defined bulk datasets with the twclient export command. For example, here are the follow graph and mention graph over users:

twclient export follow-graph -o follow-graph.csv
twclient export mention-graph -o mention-graph.csv

If you want to restrict the export to only the users specified above:

twclient export follow-graph -g subjects -o follow-graph.csv
twclient export mention-graph -g subjects -o mention-graph.csv

For other exports and other options, see the documentation.
