Nodes Overview

Nodes are the building blocks of every workflow in DotPortion. Each node performs a single, focused responsibility, and workflows are created by connecting nodes together in sequence.
This approach makes backend logic visual, predictable, and easy to maintain. This page gives you a high-level overview of all nodes available in DotPortion.
Click on any node to view its detailed documentation.

​
How Nodes Work Together

A typical workflow looks like this: 

API Start → Request Parameters → Logic → Database → API Response
  • Execution flows top to bottom
  • Data flows between nodes
  • The workflow ends when an API Response Node is executed

​
Core Nodes

​
🔹 API Start Node

Entry point of every workflow Defines how an HTTP request enters DotPortion.
  • HTTP Method
  • URL Path
  • Request entry
👉 Read API Start Node docs

​
🔹 API Response Node

Ends the workflow and sends the response Controls the final HTTP status and response body.
  • Status codes
  • Response output
  • Terminates execution
👉 Read API Response Node docs

​
Input & Validation Nodes

​
🔹 Request Parameters Node

Extract and validate incoming request data Used to define what input your API expects.
  • Body
  • Query
  • Headers
  • Path params
👉 Read Request Parameters Node docs

​
Logic & Flow Control Nodes

​
🔹 Condition Node

Control execution using conditions Allows workflows to branch based on JavaScript expressions.
  • Boolean conditions
  • Access dynamic values
  • Guard logic
👉 Read Condition Node docs

​
🔹 Logic Node

Write custom JavaScript / TypeScript Used when visual configuration is not enough.
  • Transform data
  • Perform calculations
  • Build objects
👉 Read Logic Node docs

​
🔹 Loop Node

Iterate over lists Executes connected nodes for each item in an array.
  • Sequential execution
  • Access current item
  • Bulk operations
👉 Read Loop Node docs

​
Authentication & Security Nodes

​
🔹 JWT Generate Node

Generate JSON Web Tokens Used for authentication and session handling.
  • Custom payload
  • Token expiration
  • Platform-managed secret
👉 Read JWT Generate Node docs

​
🔹 JWT Verify Node

Verify and decode JWTs Protects APIs by validating tokens.
  • Signature verification
  • Expiration checks
  • Payload decoding
👉 Read JWT Verify Node docs

​
Database Nodes

​
🔹 Database Node (Managed)

DotPortion’s built-in database No setup required. Ideal for MVPs and rapid development.
  • CRUD operations
  • Managed MongoDB
  • Project-scoped data
👉 Read Database Node docs

​
🔹 MongoDB Node (External)

Connect your own MongoDB database Used when working with existing or external databases.
  • Requires MongoDB connection URL
  • Full CRUD support
  • External data access
👉 Read MongoDB Node docs

​
Best Practices

  • Start every workflow with API Start
  • End every API workflow with API Response
  • Validate inputs early
  • Keep logic nodes focused
  • Prefer managed Database Node for quick builds
  • Use MongoDB Node for existing databases
