Hono REST API is a personal API collection built with Hono and Bun. It combines several small utility endpoints into a single service, including IP lookup, code screenshot generation, AI chat, image search, and text-to-image style generators.
The project was built for educational and personal development purposes, with a focus on experimenting with API routing, third-party data fetching, browser automation, and generator-style endpoints.
Overview
The API groups multiple endpoint categories into one Hono application. Some endpoints return simple utility data, while others generate images or fetch content from external sources.
This makes the project useful as a playground for learning how to organize API routes, handle different response types, and combine lightweight server logic with heavier worker tasks like Playwright rendering.
Problem
When experimenting with backend development, it is useful to have a single project that covers more than one kind of endpoint. A basic CRUD API teaches one pattern, but real API work often involves external requests, media generation, scraping, automation, and response normalization.
The goal of this project was to build a compact API playground that covers several of those patterns in one codebase.
Role
I implemented the Hono API structure, endpoint routing, generator endpoints, search endpoints, AI chat endpoint, and deployment flow.
I also documented usage notes and limitations so the API can be tested responsibly without assuming production-grade performance.
Stack
- Bun for the JavaScript runtime
- Hono for the HTTP API framework
- Playwright for browser-based rendering tasks
- Vercel for deployment
Features
- See request IP address
- Generate code screenshots with Carbonara-style output
- Call an AI chat endpoint
- Search images from Pinterest
- Search anime character images from Konachan
- Generate brat-style text images
- Generate quotly-style message bubble images
API Design
The API exposes a mix of utility, search, AI, and maker endpoints:
| Endpoint | Purpose |
|---|---|
/system/ip | Return the requester IP address |
/api/maker/carbonara | Create a code screenshot |
/api/ai/ai4chat | Send a prompt to an AI chat model |
/api/search/pinterest | Search images from Pinterest |
/api/search/konachan | Search anime character images |
/api/maker/brat | Generate text as an image |
/api/maker/quotly | Generate a message bubble image |
The route naming keeps each feature grouped by its category, which makes the API easier to scan and extend.
Implementation Notes
Some endpoints are lightweight and return data quickly, while generator endpoints can be slower because they rely on rendering or worker-style tasks.
The project notes mention that performance is limited when using Playwright workers on Vercel’s free tier. For faster response times, the rendering workload can be moved to local Playwright execution, a server with more predictable resources, or a dedicated worker service.
Responsible Usage
This project is intended for personal learning and experimentation. The API should not be used for abuse, spam, denial-of-service attempts, or any activity that harms a preview deployment or third-party service.
Because some endpoints rely on external sources, the implementation should be treated as experimental and may need updates when upstream services change their behavior or response structure.
Outcome
The result is a flexible Hono API playground that demonstrates route organization, utility endpoints, third-party requests, generator endpoints, and deployment tradeoffs.
It can be used as a learning project, a base for API experiments, or a reference for separating small endpoint groups inside a lightweight Hono application.
