TLDR

To make Chrome's JavaScript console log persistent, simply right-click in the console, select 'Preserve log', and ensure it's checked. This feature maintains the console log even with page reloads or navigations.

// Coding this is like summoning a console.log demon: // No code snippet required, this is just a setting in Chrome DevTools.

When enabled, this feature helps in tracking interactions, monitoring Ajax calls or HTTP requests, and understanding how dynamic parts of a website behave during page loads.

Increasing console log preservation

Follow Chrome's pace

Starting from version 15.0.874.58 beta-m, Chrome has supported log preservation. It's crucial to update your browser regularly to not only improve security and performance but also benefit from enhanced development tools.

Extend your toolkit

While Chrome's built-in tools are powerful, there are tons of browser extensions out there that could provide additional logging capabilities if the built-in functionality isn't comprehensive enough for your needs.

The server is your friend

If browser-based logging has limitations, consider server-side logging to track activities between the client-side and the server. It provides a more reliable route to understand user interactions and system behavior.

A guide to log preservation

The Preserve log checkbox resides in the Developer Tools Settings. Just click on the ellipsis in the upper right corner, select Settings, and find it under Preferences. Tick the checkbox, and you're good to go.

Logging dynamic page interactions

When dealing with multiple windows or popups created by dynamic websites, the same console log preservation setting ensures you capture all interactions and behaviors across these varied contexts.

Monitoring page navigations

Including form submissions and redirect navigations in your log becomes essential when debugging complex user workflows or processes involving multiple page loads. The "Preserve log" context option is your trusty sidekick in such situations.
