Developer Tool

Hono Telescope

Hono Telescope is an open-source monitoring and debugging tool for Hono applications running on Node.js and Bun. It provides a real-time dashboard to inspect requests, exceptions, logs, and database queries, helping developers debug faster and gain full visibility into their backend systems.

Hono Telescope Dashboard

Main Dashboard Interface

The dashboard offers a clean and structured interface, allowing developers to monitor application behavior in real-time. Logged events are grouped clearly, making it easy to trace execution flow and identify potential issues.

Core Features

Request Monitoring

Hono Telescope Request Logs

Hono Telescope logs all incoming API requests, along with details such as:

  • URL & HTTP method
  • Response time & status codes
  • Request & response payloads
  • Timestamp & runtime info

This allows developers to analyze traffic patterns and debug API behaviors efficiently.

Exception Tracking

Hono Telescope Exception Inspector

Automatic capture and display of unhandled exceptions with stack traces, making debugging runtime errors significantly easier.

Log Viewer

Hono Telescope Logged Console Output

All console logs (info, warn, error) are collected and displayed within the dashboard, tied to request context where possible.

Database Query Logging

Hono Telescope Query Inspector

Tracks database queries executed by:

  • Prisma
  • Sequelize
  • MongoDB
  • Bun SQLite

Query text, execution time, and context are recorded for performance analysis and debugging.

Simple Integration

Adding Hono Telescope requires only a few lines of code. Once initialized, it runs as a middleware inside the Hono app and can be accessed at a dedicated path (e.g., /telescope).

Tech Stack

  • Backend: Hono (Node.js / Bun)
  • Monitoring Layer: Custom middleware & hooks
  • UI: React-based dashboard
  • Database Support: Prisma, Sequelize, MongoDB, Bun SQLite
  • Open Source: MIT-licensed GitHub project

Use Case

Hono Telescope is designed for developers working with Hono APIs who need insight into application internals during development or debugging phases. It provides a transparent, developer-friendly way to track key runtime events and troubleshoot quickly.

Status

The project is currently in active development and available as an open-source tool on GitHub. Planned improvements include enhanced UI filters, real-time streaming mode, and plugin-based extension support.
