Web Profiler Bundle

A thorough utility toolkit for profiling HTTP request execution. Track runs, analyze performance, generate reports, compare results, and export data — all from the command line with local storage.

Commands

All commands accept optional <input> arguments. Without arguments, they display recent entries from their log.

Data Storage

All data is stored locally in ~/.local/share/web-profiler-bundle/. Each command maintains its own .log file with timestamped entries in YYYY-MM-DD HH:MM|value format. A unified history.log tracks all operations across commands.

Export formats supported:

• JSON — Array of objects with type, time, and value fields
• CSV — Standard comma-separated with type,time,value header
• TXT — Human-readable grouped by command type

Requirements

• Bash 4.0+ with set -euo pipefail (strict mode)
• Standard Unix utilities: date, wc, du, grep, tail, sed, cat
• No external dependencies — runs on any POSIX-compliant system

When to Use

1. Debugging slow HTTP routes — Log profiling runs with timing data and review trends over time
2. Analyzing query performance — Record database query breakdowns and compare before/after optimization
3. Inspecting middleware execution — Track middleware timing and memory consumption per request
4. Generating performance reports — Export accumulated profiling data to JSON/CSV for dashboards or CI pipelines
5. Batch profiling multiple endpoints — Profile a set of routes in one session and review aggregated statistics

Examples

# Profile a specific route
web-profiler-bundle run "POST /api/orders — 580ms, 24MB, 47 queries"

# Analyze query breakdown
web-profiler-bundle analyze "N+1 detected: users.orders — 34 queries, 210ms total"

# Compare before and after optimization
web-profiler-bundle compare "cache warm: 120ms vs cold: 890ms"

# Check middleware stack
web-profiler-bundle check "auth middleware — 12ms overhead"

# Export all profiling data to JSON
web-profiler-bundle export json

# Search for memory-related entries
web-profiler-bundle search "memory"

# View summary statistics
web-profiler-bundle stats

How It Works

Web Profiler Bundle stores all data locally in ~/.local/share/web-profiler-bundle/. Each command creates a dedicated log file (e.g., run.log, analyze.log, report.log). Every entry is timestamped and appended, providing a full audit trail of all profiling activity. The history.log file aggregates operations across all commands for unified tracking.

When called without arguments, each command displays its most recent 20 entries, making it easy to review past profiling work without manually inspecting log files.

Output

All output goes to stdout. Redirect to a file with:

web-profiler-bundle stats > report.txt
web-profiler-bundle export json  # writes to ~/.local/share/web-profiler-bundle/export.json
