Session: How to Evict Single Entity from a Session

We can clear all session operations and stop tracking of all entities using the session.advanced.clear() method, there's a need to do cleanup only for one entity. This is what evict() is for.

Syntax

session.advanced.evict(entity);

Example I

const employee1 = new Employee();
employee1.firstName = "John";
employee1.lastName = "Doe";

const employee2 = new Employee();
employee2.firstName = "Joe";
employee2.lastName = "Shmoe";

await session.store(employee1);
await session.store(employee2);

session.advanced.evict(employee1);

await session.saveChanges();        // only 'Joe Shmoe' will be saved

Example II

let employee = await session.load("employees/1-A"); // loading from serer
employee = await session.load("employees/1-A");     // no server call
session.advanced.evict(employee);
employee = await session.load("employees/1-A");     // loading from server
