Created a "Free Operation" LINE Bot Tax Return App with Cloudflare Workers x Gemini 2.0
Analysis
This article details the development of a LINE Bot for tax return assistance, leveraging Cloudflare Workers and Gemini 2.0 to achieve a "free operation" model. The author explains the architectural choices, specifically why they moved away from a GAS-only (Google Apps Script) setup and opted for Cloudflare Workers. The focus is on the reasoning behind these decisions, particularly concerning scalability and user experience limitations of GAS. The article targets developers familiar with LINE Bot and GAS who are seeking solutions to overcome these limitations. The core argument is that while GAS is useful, it shouldn't be the primary component in a scalable application.
Key Takeaways
- •Cloudflare Workers can be used to create cost-effective LINE Bots.
- •GAS has limitations in terms of scalability and UX for complex applications.
- •AI can automate tax return tasks like receipt categorization.
