Systems and/or methods for dynamically configuring and evaluating rules with dynamic and/or user inputs at runtime

A non-transitory computer readable storage medium tangibly storing instruction that, when executed by a processor of a client-side client device, execute a web application, the web application being coded to operate in one of a plurality of different modes, a first mode permitting central rule configuration while prohibiting client-side rule configuration, and a second mode permitting client-side rule configuration, the execution of the web application comprising:

• in response to an instance of the web application being started up, retrieving metadata using a computer-executable retrieval service embedded in the web application and invoked at a bootstrap hook, the metadata being associated with earmarked programmatic elements in the web application;
• dynamically evaluating, at the client-side client device using an evaluation service embedded in the web application and injected into operation of the instance of the web application, one or more configured rules against input provided in connection with the instance of the web application, the rules being definable in relation to the earmarked programmatic elements using the retrieved metadata, the rules specifying behavior of the web application and being configured in accordance with the mode in which the web application is coded to operate, the rules being both dynamically configurable and dynamically reconfigurable while the instance of the web application is running and being dynamically effective thereafter in the evaluation without requiring redeployment of the web application, even if (re)configured while the instance of the web application is running;
• and
• controlling the operation of the instance of the web application responsive to the evaluation.

A client-side client device, comprising:

• at least one processor and a memory, the at least one processor being configured to execute a web application, the web application being coded to operate in one of a plurality of different modes, a first mode permitting central rule configuration while prohibiting client-side rule configuration, and a second mode permitting client-side rule configuration, wherein
• in response to an instance of the web application being started up, metadata is retrieved using a computer-executable retrieval service embedded in the web application and invoked at a bootstrap hook, the metadata being associated with earmarked programmatic elements in the web application;
• using an evaluation service embedded in the web application and injected into operation of the instance of the web application, one or more configured rules is/are dynamically evaluated against input provided in connection with the instance of the web application, the rules being definable in relation to the earmarked programmatic elements using the retrieved metadata, the rules specifying behavior of the web application and being configured in accordance with the mode in which the web application is coded to operate, the rules being both dynamically configurable and dynamically reconfigurable while the instance of the web application is running and being dynamically effective thereafter in the evaluation without requiring redeployment of the web application, even if (re)configured while the instance of the web application is running;
• and
• the operation of the instance of the web application is controlled responsive to the evaluation.
