Overview

This is a Redmine plugin that progressively loads issue history on demand. Instead of loading all journals at once, it displays only the latest N entries initially and allows users to load older entries by clicking a "Show more" button.

This improves page load performance for issues with many history entries.

Features

  • Progressive Loading: Display only the latest N journals initially
  • On-Demand Loading: Load older journals with a single button click
  • Quick Full Load: Shift + click on "Show more" to load all remaining journals at once
  • Custom Event Hook: Emits a lazyLoadHistory:loaded event after journals are loaded
  • Configurable: Set the initial display count and load count per request via Administration or each user's My account preferences

Installation notes

1. Clone the plugin

cd /path/to/redmine/plugins
git clone https://github.com/sk-ys/redmine_lazy_load_history.git

2. Restart Redmine
