Serialization is a process of converting an apex object into stream of bytes so that it can be transferred over a network or stored in a salesforce record. Deserialization is the exact opposite – which convert bytes of stream into object. This serialization/deserialization process should be considered properly while implementing. As this is extra layer over object which can add extra time for application load/performance, we should not always consider it blindly. This should only have implemented where it is required.  There is other problem with this serialization/deserialization process is, it can insecure for application. See article of OWASP for insecure…

Apex code coverage is important when we move code from one Sandbox to other or production environment. In sandbox environment, we can move code without minimum code coverage but for production, we need minimum 75% code coverage for custom apex code. Checking Org’s Apex Code Coverage: We can check code coverage using Apex class screen. Checking Individual Apex Class Code Coverage: We can check individual apex code class coverage from Developer console by running test class. It will give result with code coverage percentage with each class. We can check this report on screen but we can not export or…

A single Salesforce orgs can be utilized by multiple clients.

We have to create apex class to call this API and we are showing that in LWC component. Based on your requirement, you can use use this information.…
