Custom Expressions & Custom Functions
Bridge the gap between low-code speed and pro-code flexibility.
In the public sector, "off-the-shelf" rarely fits perfectly. Every agency has unique regulatory logic, complex mathematical formulas, or specific data validation rules. SnapApp’s Custom Expressions & Functions empower you to extend your application’s core functionality using GenAI, ensuring your solution is as unique as your mission.
Write Code Without Being a Coder
SnapApp leverages advanced Generative AI to turn natural language into high-performance custom code. Whether you need a complex tax calculation or a unique data transformation, you simply describe the logic, and SnapApp writes the expression for you.
Natural Language Logic
Describe your requirement (e.g., "Calculate a 5% late fee if the submission date is 30 days past the due date") and let AI generate the script.
Text to CodeInstant Validation
AI-generated functions are automatically tested for syntax and logic errors before deployment, ensuring zero runtime crashes.
Error ProofExtensible Library
Save your custom functions to a private library for reuse across multiple agency modules, saving development time.
Modular ReuseAdvanced Functionality for Complex Missions
While SnapApp is a low-code leader, we don't believe in "walled gardens." For technical teams, our platform provides a robust environment to inject custom JavaScript or Python-based expressions to handle:
Clean and reformat data from legacy systems in real-time using Python scripts.
Create sophisticated "if-this-then-that" logic that goes beyond standard drag-and-drop capabilities.
Execute mission-specific algorithms directly within your app's workflow without external calls.
Safe, Secure, and Governed
We understand that custom code in government requires oversight. SnapApp includes built-in guardrails to ensure that AI-generated logic remains secure and compliant.
Sandbox Environment
Test all custom expressions in an isolated environment before they touch live citizen data.
Audit Logs
Every change to a custom function is tracked, versioned, and attributed to a specific user.
Governance Controls
IT Administrators can restrict who has the authority to generate or approve custom functions.
Frequently Asked Questions
Not necessarily. For simple logic (like math formulas or basic data reformatting), our GenAI Assistant allows business analysts to describe the requirement in plain English. For complex system integrations or heavy-duty data processing, we recommend a technical lead oversee the process.
Security is our baseline. All code generated by SnapApp's GenAI is Non-Executing by Default (staged in sandbox), Scanned for Vulnerabilities automatically, and requires Human-in-the-Loop approval before deployment.
SnapApp primarily supports JavaScript (Node.js) and Python, the industry standards for cloud-based extensibility. This ensures that any code written or generated is easy to maintain and compatible with the broader Google Cloud ecosystem.
Absolutely not. We use Enterprise-grade GenAI models through Google Cloud's Vertex AI. Your prompts, custom code, and agency data are never used to train the public models. Your intellectual property remains entirely within your secure tenant.
Yes. Every custom expression is subject to Full Version Control. If a new update causes an issue, you can roll back to the previous "known good" version with a single click, ensuring zero downtime.
Ready to extend your possibilities?
Standard low-code platforms force you to change your business processes to fit their limitations. SnapApp does the opposite. Combine low-code speed with AI-generated custom functions today.
