JavaScript Reductor for Webpage Rendering Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The delay in rendering webpages due to the collection of various embedded content objects, such as Javascript scripts and images, can slow down the presentation of webpages and consume substantial bandwidth.
Innovation Solution
A system and method that replaces embedded content objects with stubs, injects reporting instructions, and prioritizes content objects based on usage patterns, allowing high-priority objects to be quickly accessed and cached, while low-priority objects remain accessible via stubs, thereby improving rendering speed and reducing bandwidth consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all embedded content objects are collected to ensure proper webpage rendering, then rendering completeness is improved, but webpage presentation time increases
Solution Approach 1:
The patent segments content objects into different priority levels (high-priority and low-priority). High-priority content objects are collected and made available before webpage presentation, while low-priority objects are loaded asynchronously or on-demand. This segmentation allows the webpage to be presented promptly with essential content while maintaining rendering completeness through subsequent loading of additional content objects.
2Reliability
If all embedded content objects are collected to ensure proper webpage rendering, then rendering completeness is improved, but bandwidth consumption increases
Solution Approach 1:
The patent segments content objects into different priority levels (high-priority and low-priority). High-priority content objects are collected and made available before webpage presentation, while low-priority objects are loaded asynchronously or on-demand. This segmentation allows the webpage to be presented promptly with essential content while maintaining rendering completeness through subsequent loading of additional content objects.
Solution Approach 2:
The patent applies partial action by collecting only the necessary high-priority content objects needed for initial webpage rendering, rather than collecting all content objects upfront. Low-priority content objects are loaded partially or on-demand as needed, reducing initial bandwidth consumption while still ensuring eventual rendering completeness.
3Speed
If content objects are prioritized and only high-priority objects are quickly accessed, then rendering speed is improved, but access to low-priority objects may be delayed
Solution Approach 1:
The patent applies preliminary action by pre-collecting and pre-processing high-priority content objects before webpage presentation. This allows the webpage to be rendered quickly with essential content available immediately. Low-priority content objects are prepared for subsequent loading, ensuring that while they may be accessed later, the critical rendering path is not blocked by their loading times.

AI summary
A system can be provided for dynamically serving a content file. A content object request function can receive a request for a webpage defined by the content file, the content file including a plurality of embedded or referenced content objects, at least one of the plurality of content objects including a Javascript. A content-file modifier can modify the content file to include instructions to generate reports comprising information relating to invocation of stubs. A report receiver can receive reports from the end user system, and an object usage analyzer quantifes usage of each of the stubs. An object prioritizor can prioritize the plurality of content objects based on the analysis, the prioritization including an identification of at least one high-priority content object. An object injector can modify the content file such that the high-priority content object automatically loads upon rendering of the content file.
