ECMAScript Local Storage Versioning for Web Load Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for website and client interaction are inefficient due to the need for multiple requests to retrieve and update ECMAScript files, which are not easily updateable and can lead to unnecessary server requests and caching issues.
Innovation Solution
Storing ECMAScript files and their version numbers in an HTML5 local storage database on the client, allowing for comparison with server versions and updating only when necessary, thereby reducing the number of requests and improving loading speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If ECMAScript files are downloaded from server on each request or with cache policy, then scripts can be updated, but the number of requests increases and interaction speed decreases
Solution Approach 1:
The patent stores ECMAScript files in the browser's local storage database before they are needed, so that when the website is accessed, the scripts are already available locally without requiring server requests. This preliminary storage action eliminates the need for multiple requests and significantly improves interaction speed.
Solution Approach 2:
The patent creates local copies of ECMAScript files in the browser's local storage database. Instead of repeatedly downloading from the server, the browser stores copies of these files locally and retrieves them from local storage, reducing the number of server requests and improving loading speed.
2Productivity
If ECMAScript files are cached locally, then request frequency decreases, but updating scripts becomes difficult
Solution Approach 1:
The patent implements a version number checking mechanism where the browser compares the version number of locally stored ECMAScript files with the version number provided by the server. This feedback loop allows the system to automatically detect when updates are available and trigger appropriate actions, balancing local caching with update capability.
Solution Approach 2:
The patent makes the local storage system dynamic by implementing version comparison logic. The system can adapt its behavior based on version mismatches: if the local version is outdated, it retrieves the updated script from the server; if versions match, it uses the local copy. This dynamic approach maintains both caching efficiency and update capability.
3Speed
If extensive cache policy is set to prevent server requests, then interaction speed improves, but script content updating is prevented
Solution Approach 1:
The patent uses version number comparison as a feedback mechanism to determine whether to use cached scripts or fetch updated ones from the server. This ensures that scripts are reliably updated when changes are made on the server while maintaining fast local loading when no updates are available.
Solution Approach 2:
The patent performs preliminary version checking before executing scripts. By comparing version numbers in advance, the system can determine whether cached scripts are current or need updating, ensuring reliability without sacrificing loading speed.
Data Source
AI summary
A method for increasing interaction speed between a website and a client device includes storing on an HTML5 local storage database on the client an ECMAScript file and a parameter from a web server of the website, and subsequently comparing a web server version number of the ECMAScript from the web server with the local version number of the parameter stored on the HTML5 local storage database. The parameter specifies a local version number of the ECMAScript file. The method can also include updating the ECMAScript stored on the HTML5 local storage database with the ECMAScript file from the web server when the web server version number is greater than the local version number. The method can also include loading the website on the client by retrieving the ECMAScript file from the HTML5 local storage database. Retrieving the ECMAScript file from the HTML5 local storage database can occur when the web server version number is the same as the local version number. The method can also include loading the website on the client by retrieving the ECMAScript file from the HTML5 local storage database.
