BAS - Business Automation System

Many organizations and individuals rely on automation across various contexts in their daily operations. With BAS, we aim to provide an open-source platform that empowers users to create customized automation systems tailored to their unique requirements. BAS consists of a series of abstract components designed to facilitate the creation of diverse bots, regardless of context.

The underlying idea is to develop generic components that can serve a wide range of needs, this approach ensures that all members of the community can leverage the platform's evolving suite of components and bots to their advantage.

Install the gem and add to the application's Gemfile by executing:

$ bundle add bas

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install bas

A bot is a tool in charge of executing a specific automation task. The pipeline of a bot consists of reading from a data source, processing a specific task, and then writing a result in storage.

A use case is an automation problem greater than the one managed by a single bot. A use case comprises a set of bots that are agnostic between them and each one solves a specific task (parts of the automation problem). To connect the bots, a shared storage should be used. This shared storage could be a PostgresDB database, an S3 bucket, or any kind of storage where the bots will read and write data so another bot can use it to execute their tasks.

For example, a system to notify birthdays in a company (automation problem) can be solved with three bots: one to fetch the data from an external data source, one to format the birthday message, and the last one to notify somewhere.

The gem provides with basic interfaces, types, and methods to shape your own bot in an easy way. Since the process of reading and writing in a shared storage is separated from the main task, two base classes were defined to deal with this executions, leaving the logic of the specific task in the bot file.

Specifically, a reader is an object in charged of bringing data from a shared storage. The gem already provides the base interface for building your own reader for your specific shared storage, or rely on already built classes if they match your purpose.

The base interface for a reader can be found under the bas/read/base.rb class.

The Write is in charge of creating or updating information in a shared storage. This is the last step for every BOT. These changes can be a transaction in a database, adding files in a cloud storage, or simply creating logs.

The base interface for a writer can be found under the bas/write/base.rb class.

The bot execute the logic to solve an specific task. For this, it can use the data from the read step, and then returns a processed response to be wrote by the write component. Every bot reads from a shared storage and writes in a shared storage.

The base interface for a bot can be found under the bas/bot/base.rb class.

In this example, we demonstrate how to instantiate a birthday notification bot and execute it in a basic Ruby project. We'll also cover its deployment in a serverless configuration, specifically using a simple Lambda deployment.

We'll need some configurations for this specific use case:

• A Notion database ID, from a database with the following structure:

With the following formula for the BD_this_year column: dateAdd(prop("BD"), year(now()) - year(prop("BD")), "years")

• A Notion secret, which can be obtained, by creating an integration here: https://developers.notion.com/, browsing on the View my integrations option, and selecting the New Integration or Create new integration buttons.

The specific bot can be found in the bas/bot/fetch_birthdays_from_notion.rb file.

Normal ruby code

options = {
  process_options: {
    database_id: "notion database id",
    secret: "notion secret"
  },
  write_options: {
    connection: {
      host: "host",
      port: 5432,
      dbname: "bas",
      user: "postgres",
      password: "postgres"
    },
    db_table: "use_cases",
    bot_name: "FetchBirthdaysFromNotion"
  }
}

bot = Bot::FetchBirthdaysFromNotion.new(options)
bot.execute

For implementation details, please refer to the examples folder in the repository. You can find an example of how to configure a Lambda function with a bot there.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

Features and bug fixes are listed in the CHANGELOG file.
