Environment File

An environment file .env is used to store Twitter API credentials and MongoDB details.

Step 1. Set the default config for the .env file:

• Every twitter2mongodb command will now use the designated .env file

twitter2mongodb config set env path/to/.env

Step 2. Set Twitter API credentials

twitter2mongodb env set TWITTER_CONSUMER_KEY ***
twitter2mongodb env set TWITTER_CONSUMER_SECRET ***
twitter2mongodb env set TWITTER_ACCESS_TOKEN_KEY ***
twitter2mongodb env set TWITTER_ACCESS_TOKEN_SECRET ***

Step 3. Set MongoDB connection

twitter2mongodb env set MONGODB_CONNECTION mongodb://localhost:27017

REST API

The REST API obtains Twitter data in batches using search queries.

Step 1. Setup default twitter options:

1. Set Twitter REST method (one of get, post, delete or stream)
2. Set Twitter path
3. Set Twitter parameters for path

twitter2mongodb config set twitter.method get
twitter2mongodb config set twitter.path search/tweets
twitter2mongodb config set twitter.params "{\"q\":\"twitter\"}"

Step 2. Setup default MongoDB options:

1. Set database to store streamed Twitter data
2. Set collection to store streamed Twitter data
3. Set MongoDB query method for streamed Twitter data
4. Set jsonata filter before inserting

twitter2mongodb config set mongodb.database twitter2mongodb_database
twitter2mongodb config set mongodb.collection twitter_data
twitter2mongodb config set mongodb.method insertMany
twitter2mongodb config set jsonata statuses

Step 3. Extract Twitter data into MongoDB collection given setup options:

twitter2mongodb > log.csv

Stream API

The Stream API obtains Twitter data in real-time using tracking filters.

Step 1. Setup default twitter options:

1. Set Twitter stream method
2. Set Twitter path
3. Set Twitter stream parameters

twitter2mongodb config set twitter.method stream
twitter2mongodb config set twitter.path statuses/filter
twitter2mongodb config set twitter.params "{\"track\":\"twitter\"}"

Step 2. Setup default MongoDB options:

1. Set database to store streamed Twitter data
2. Set collection to store streamed Twitter data
3. Set MongoDB query method for streamed Twitter data

twitter2mongodb config set mongodb.database twitter2mongodb_database
twitter2mongodb config set mongodb.collection twitter_data
twitter2mongodb config set mongodb.method insertOne

Step 3a. Stream Twitter data into MongoDB collection given setup options:

twitter2mongodb > log.csv

Step 3b. Stream Twitter data into a MongoDB collection as a service:

1. Save a node runnable script of the current options
2. Install pm2 (npm install pm2 -g)
3. Use pm2 to run the saved script as a service

twitter2mongodb save path/to/script.js
pm2 start path/to/script.js
pm2 save

The logs are in the following Comma-Separated Values (CSV) format:

• time_iso8601: Time and date in ISO 8601 format
• status: Status of the log
• message: Relevant messages
• json: JSON object containing relevant debugging information
