Daggerverse Repository

Welcome to the Daggerverse repository, a collection of Dagger modules designed and built by Emmanuel Sibanda. This repository aims to automate various aspects of financial data processing, analysis, and test generation. Below is a detailed yet concise overview of each module to ensure engineering managers can quickly understand and evaluate the technical capabilities presented here.

What is Dagger?

Dagger is a programmable tool that allows you to replace your software project's artisanal scripts with a modern API and cross-language scripting engine. It simplifies and automates complex workflows, making development and deployment processes more efficient.

Example Call

dagger call categorize --data='[{"Description": "Dinner at Italian restaurant", "Amount": 120}]' --hftoken=env:HUGGING_FACE_TOKEN

Expected Output

{
  "Transactions": [
    {
      "Description": "Dinner at Italian restaurant",
      "Amount": 120,
      "Category": "Takeouts"
    }
  ]
}

2. Sveltekit Unit Test Generator with LangChain

Description

This module automates the generation of unit tests for Sveltekit projects using LangChain AI capabilities, improving developer productivity.

Functionality

• GenerateUnitTests: Utilizes LangChain's ChatOpenAI model to create unit tests based on system messages and human input prompts.

3. FetchSpreadsheetData

Overview

Automates fetching transaction data from Google Spreadsheets populated by Tiller, converting it into structured JSON for financial analysis and expense management.

Functionality

• Securely connects to Google Sheets and retrieves transaction data.
• Parses data into structured JSON.
• Handles errors gracefully.

Usage

dagger call fetch-data --apiKey=env:[KEY] --sheet=env:[KEY]

4. FilterForNewTransactions

Overview

Filters new transactional data from a given spreadsheet against existing records in MongoDB, isolating transactions not yet recorded.

Features

• Filters existing transactions based on unique identifiers.
• Interfaces with MongoDB for authentication and retrieval.
• Handles retries and exceptions.

Example Usage

dagger call filter --data=[DATA] --connection=env:[KEY] --database=[DBNAME] --collection=[COLLECTIONNAME]

5. GetAdvice

Overview

Provides personalized financial advice using AI, aiding in budget management and financial planning. Integrates LangChain with OpenAI's GPT models to process data and deliver insights.

Functions

• generate: Provides insights on weekly spending and budget adherence.
• update_prompt: Updates initial prompts based on user feedback and regenerates advice.

Example Usage

dagger call generate --data='{"current_week": {"Groceries": "$150", "Utilities": "$120"}, "previous_weeks": {"Groceries": "$130", "Utilities": "$110"}}' --openai=env:OPENAI_SECRET --connection=env:DB_CONNECTION

dagger call update_prompt --feedback='I prefer more savings tips.' --data='{"current_week": {"Groceries": "$150", "Utilities": "$120"}, "previous_weeks": {"Groceries": "$130", "Utilities": "$110"}}' --openai=env:OPENAI_SECRET --connection=env:DB_CONNECTION

6. GetFromMongo

Overview

Facilitates advanced data retrieval and aggregation from MongoDB using Atlas Search, providing detailed financial insights by grouping transactions by weeks and categories.

Example Usage

dagger call get-data --connection=env:MONGO --database=[DBNAME] --collection=[COLLECTIONNAME]

7. NodeJS Unit Test Runner

Overview

Runs unit tests in a containerized environment for NodeJS projects, ensuring consistent test results across different environments.

Example Usage

dagger call test

dagger call build-test --src=../../ --repo=emms21/interviewsageai --tag=latest

Dependencies
