Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

cf-log-viewer

A local web-based viewer for Cloud Foundry application logs. Parses the raw cf logs output into a structured, filterable table with drill-down into individual log entries.

Prerequisites

You need the Cloud Foundry CLI installed and authenticated before using this tool.

# Install the CF CLI (if not already installed)
# macOS
brew install cloudfoundry/tap/cf-cli@8

# Login to your CF environment
cf login -a <API_ENDPOINT>

# Or with SSO
cf login -a <API_ENDPOINT> --sso

Make sure you can run cf logs <app-name> --recent successfully before using this tool.

Usage

npx cf-log-viewer <app-name>

This will:

  1. Run cf logs <app-name> --recent and parse the output
  2. Start a local web server on a random port
  3. Open your browser with the log viewer

Options

npx cf-log-viewer <app-name> --live       # also stream live logs
npx cf-log-viewer <app-name> --no-open    # don't auto-open browser

Features

  • Structured table view -- timestamp, level, source, logger, message, correlation ID
  • Color-coded levels -- error (red), warn (yellow), info (blue), debug (gray)
  • Filtering -- by level, logger, correlation ID, or free-text search
  • Drill-down detail panel -- click any row to see categorized fields:
    • Message & core info
    • HTTP context (forwarded path, host, user agent)
    • Tracing & correlation (trace IDs, span IDs, SAP Passport)
    • Infrastructure (org, space, container, CF instance)
    • Raw JSON with syntax highlighting
  • Correlation grouping -- click a correlation ID to filter all entries for that request
  • Live streaming -- with --live, new log entries appear in real-time via WebSocket
  • Download -- export filtered logs as JSON
