Syntax

addToContext(key, value, mode)

​
Description

Adds a value to the Context object. Parameters:
  • key: string — the key in the Context object where the value should be stored.
  • value: unknown — the value to store.
  • mode: "simple" | "array":
    • "simple" — stores the value directly at the specified key, replacing any existing value.
    • "array" — adds the value to an array at the specified key, creating the array if it doesn’t exist.
Returns: void

Example

// Initial context: {}
addToContext("user.city", "Berlin", "simple");
// Context after execution: { user: { city: "Berlin" } }
// If called again with same key:
addToContext("user.city", "Munich", "simple");
// Context after execution: { user: { city: "Munich" } }  // Overwrites previous value

// Initial context: {}
addToContext("user.purchases", "book", "array");
// Context after execution: { user: { purchases: ["book"] } }

// Adding more items to the same array:
addToContext("user.purchases", "laptop", "array");
addToContext("user.purchases", "coffee", "array");
// Context after execution: { user: { purchases: ["book", "laptop", "coffee"] } }
