Interactive Web Page Rendering With Critical Script Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rendering interactive web pages is slow due to the processing of scripts that halt the creation of the Document Object Model (DOM) tree, leading to increased time to first contentful paint (FCP) and time to interaction (TTI), negatively impacting user experience.
Innovation Solution
Distinguish between critical and non-critical components, communicating critical components in the HTML head to the client device for early download and processing, while non-critical components are downloaded later, utilizing server-side rendering when appropriate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If scripts for interactive elements are processed sequentially, then interactivity is provided, but the time to first contentful paint and time to interaction increase
Solution Approach 1:
The patent segments web page components into critical and non-critical categories. Critical components (such as above-the-fold content and essential interactivity) are prioritized for early rendering, while non-critical components are deferred. This segmentation allows the browser to render visible content faster without sacrificing essential interactivity, directly resolving the contradiction between providing interactivity and reducing time to first contentful paint.
Solution Approach 2:
The patent implements preliminary actions by pre-loading critical components and resources during the initial page load phase. The system identifies and prioritizes critical interactivity scripts that must be available immediately for user interaction, while non-critical scripts are loaded asynchronously in the background. This preliminary prioritization reduces time to interaction while maintaining full interactivity functionality.
2Reliability
If all components are downloaded and processed, then complete interactivity is achieved, but rendering speed decreases
Solution Approach 1:
The system performs preliminary actions by pre-identifying and pre-loading only the critical components required for initial rendering and essential interactivity. Non-critical components are identified but not immediately processed,而是 loaded asynchronously after the critical path is complete. This approach achieves complete interactivity eventually while significantly improving initial rendering speed.
Solution Approach 2:
The patent applies partial action by initially loading and rendering only the necessary subset of components (critical components) rather than all components. This partial rendering provides immediate visual feedback to users while the remaining non-critical components are loaded in the background. The system performs exactly enough action initially to satisfy user needs, avoiding the performance penalty of processing everything upfront.
3Reliability
If scripts are executed before rendering, then interactivity is ensured, but time to first contentful paint increases
Solution Approach 1:
The patent segments scripts into critical and non-critical categories based on their execution timing requirements. Critical scripts that must execute before rendering are identified and executed in priority, while non-critical scripts are deferred to execute after rendering begins. This segmentation ensures essential interactivity is maintained while allowing rendering to proceed without unnecessary delays.
Solution Approach 2:
The system performs preliminary execution of critical scripts that are required for rendering and essential interactivity. These scripts are executed in advance during the critical path, while non-critical scripts are executed asynchronously after rendering has commenced. This preliminary prioritization of script execution ensures that interactivity requirements are met without blocking the rendering process.
Data Source
AI summary
Systems and methods for rendering interactive web pages are disclosed. A disclosed method includes receiving a web page request, retrieving web page content for the web page, identifying one or more components that provide interactivity to the web page in the web content, determining whether the one or more components are critical components and communicating the determined one or more critical components in a Hypertext Markup Language (HTML) head and communicating the remainder of the web content in an HTML body.
