Dynamic Service Worker Code for Persistent Browser Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web browser storage mechanisms, such as cookies, are not suitable for long-term data storage as they are temporary and can be deleted, making them unsuitable for applications that require persistent data retention.
Innovation Solution
The method involves dynamically generating service worker code in a web browser to store data, which is less likely to be deleted and can persist across multiple sessions, by embedding data into the service worker code and updating its version number to distinguish modified versions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cookies or session storage are used to store data in the web browser, then the data can be easily accessed and stored, but the data is temporary and periodically deleted by the browser
Solution Approach 1:
The patent changes the storage mechanism from temporary cookie-based storage to service worker code embedding, fundamentally altering how data is stored in the browser. The service worker code is executed and stored as part of the browser's service worker infrastructure, which persists across sessions unlike temporary cookies
Solution Approach 2:
The patent embeds data directly into the service worker code, creating a persistent copy of the data within the browser's executable code structure. This embedded data survives browser sessions and clears, unlike temporary storage mechanisms
2Device complexity
If data is stored in cookies, then the storage mechanism is simple and widely supported, but the data cannot persist for long periods of time
Solution Approach 1:
The service worker code serves multiple functions: it acts as both the executable service worker script and as a persistent data storage medium. By embedding data within the service worker code, the system achieves long-term data retention while maintaining browser compatibility through the widely-supported service worker API
3Ease of operation
If temporary storage mechanisms like cookies are used, then the browser can easily manage and clean up storage, but repeated requests must be sent to the online system
Solution Approach 1:
The patent performs preliminary action by embedding data into the service worker code during the service worker installation or update process. This pre-stored data is then immediately available for retrieval without requiring repeated requests to the online system, improving website operation efficiency
Solution Approach 2:
The service worker code with embedded data enables the browser to serve itself by retrieving stored data locally without needing to contact the online system repeatedly. The service worker acts as a self-contained data storage and retrieval mechanism
Data Source
AI summary
Systems and methods for storing information in a web browser by dynamically generating service worker codes are provided. In one example, an online system receives a request from a client device to store data included in the request in a service worker code. The online system modifies a source code of a particular service worker code to include the data to be stored and transmits the modified service worker code to the client device. The client device receives and stores the modified service worker code embedded with the data. The client device receives a request for a particular data associated with a web page and determines that the modified service worker code contains the requested particular data. The client device retrieves the requested particular data from the modified service worker code and updates the web page with the retrieved particular data.
