Xano Backend Masterclass: APIs Without Writing Code

Xano is a game-changer for no-code developers. It provides a powerful backend without writing a single line of code. Let's master it together.

What Makes Xano Special?

Visual API Builder - Create RESTful APIs visually. No code required.

Powerful Database - PostgreSQL under the hood with a visual interface.

Function Stacks - Build complex logic with drag-and-drop functions.

Scalability - Enterprise-grade infrastructure that scales automatically.

Database Design

Start with your data model:

1. Create tables for each entity
2. Define field types carefully
3. Set up relationships (one-to-many, many-to-many)
4. Add indexes for performance

Best Practice: Normalize your data. Avoid duplicating information across tables.

Building APIs

Xano's API builder is intuitive:

Endpoints - Define your routes (GET, POST, PUT, DELETE)

Inputs - Accept parameters from requests

Function Stack - Process data step by step

Response - Return structured JSON

Authentication

Implement secure authentication:

1. Create a User table with email and password
2. Use Xano's built-in auth functions
3. Generate JWT tokens
4. Protect endpoints with auth middleware

Advanced Function Stacks

Chain operations together: - Database queries - Conditional logic - Loops and iterations - External API calls - Data transformations

Connecting to Front-ends

Xano works with any front-end: - Bubble.io - FlutterFlow - Webflow - React/Vue/Angular - Mobile apps

Use the auto-generated API documentation to integrate quickly.

Performance Tips

• Use pagination for large datasets
• Implement caching where appropriate
• Optimize database queries
• Use background tasks for heavy operations

Scaling Your Backend

Xano handles scaling automatically: - Horizontal scaling - Load balancing - Database optimization - CDN for static assets

Xano eliminates the complexity of backend development while giving you enterprise-grade capabilities.
