Switch Node

Type: Function

Compatible with: Flow Graph, Connector Graph

Description:

The Switch Node acts as a conditional router for messages, directing them to different outputs based on the value of a specified property or their position in a sequence. This node enables dynamic decision-making within your flows, allowing you to create branching logic based on various conditions.

Settings Parameters (Rules):

• Property: The dot-notation path to the property within the msg object that you want to evaluate (e.g., msg.payload.status). Alternatively, you can select "env." to evaluate an environment variable.
• Comparison Operator: Choose a comparison operator (e.g. == != > < contains, regex) to define the matching condition.
• Value/Pattern: Enter the value or pattern to compare against the property. For "contains" and "regex," enter a string or regular expression.
• Output: Select the output port (1, 2, etc.) to which the message should be sent if the rule matches.

Additional Settings:

• Verify all the rules: Evaluates all rules and sends the message to all matching outputs.
• Stops when match: Stops evaluating rules as soon as one rule matches and sends the message to the corresponding output.

Input:

• msg: The message object whose property will be evaluated against the defined rules.

Outputs:

• Multiple outputs (1, 2, etc.), each corresponding to a specific rule.
