Advanced Tips and Tricks for Mastering ASPRunner ProfessionalASPRunner Professional is a powerful RAD (rapid application development) tool that lets developers generate data-driven web applications from databases quickly. If you already know the basics, this article shows advanced techniques, best practices, and practical tricks to maximize productivity, performance, security, and maintainability when using ASPRunner Professional.
1. Project Structure and Team Collaboration
- Use a consistent project naming scheme that includes environment and module (e.g., sales_crm_prod, sales_crm_dev).
- Store the generated project files and source assets (images, custom code, CSS, JS) in version control (Git). Commit the ASPRunner project file (*.aspxproj or similar), custom code folders, and exported SQL scripts.
- Separate environment-specific settings (connection strings, API keys) from project files. Keep a template config file (config.example.php/.config) and environment-specific overrides excluded from Git via .gitignore.
- If multiple developers work on the same app, define clear responsibilities: who handles database schema, UI/UX, server deployment, and custom business logic.
2. Database Design & Optimization
- Normalize where appropriate, but don’t over-normalize. Use denormalization for read-heavy report pages to reduce complex joins.
- Add meaningful indexes on columns used in WHERE, ORDER BY, JOIN, and lookup filters. Monitor query plans and slow queries.
- Use views for complex reporting queries. Point ASPRunner at a view to simplify security and reduce application-layer complexity.
- Use stored procedures for multi-step transactions or heavy data processing; call them from ASPRunner to keep heavy logic in the database.
3. Efficient Use of Lookups and Master-Detail Pages
- For large lookup tables, enable AJAX lookups in ASPRunner to avoid loading thousands of records into page load. Set minimum character thresholds before a lookup fires.
- Use cached lookup values when data changes infrequently; implement server-side caching or leverage the DBMS query cache.
- Implement master-detail relations for parent-child data (orders and order_items). Use inline add/edit for detail rows when appropriate to improve user workflow.
4. Client-Side Customization: JavaScript & Events
- Use ASPRunner’s client-side events (BeforeShow, AfterEdit, AfterAdd) to insert custom JavaScript for enhanced UX (dynamic field show/hide, custom validation).
- Keep JavaScript modular: place functions in separate JS files and include them via the project’s layout or page-specific settings. This aids reusability and maintenance.
- Debounce user input handlers (e.g., onKeyup) to prevent excessive server calls. Example debounce pattern:
function debounce(fn, delay) { let timer; return function(...args) { clearTimeout(timer); timer = setTimeout(() => fn.apply(this, args), delay); }; } - Use mutation observers sparingly to watch for dynamic element changes created by ASPRunner components.
5. Server-Side Events and Business Logic
- Keep heavy data processing on the server side using ASPRunner’s server events (BeforeAdd, AfterEdit, BeforeProcessList). This ensures data integrity and prevents manipulation from the client.
- Use transactions inside server events when multiple related tables are affected; rollback on error to maintain consistency. Example (pseudo):
$conn->BeginTrans(); try { // insert into orders // insert order_items $conn->CommitTrans(); } catch (Exception $e) { $conn->RollbackTrans(); throw $e; } - Validate all inputs server-side even if client-side validation exists.
6. Security Best Practices
- Enforce role-based access control (RBAC). Define clear roles and use ASPRunner’s permissions to hide pages/fields and restrict CRUD operations.
- Protect against SQL injection by using parameterized queries and ASPRunner’s built-in query mechanisms. Avoid concatenating user input into SQL strings.
- Use HTTPS everywhere. Configure HSTS on the server and prevent mixed-content issues by serving all scripts and assets over HTTPS.
- Implement CSRF protection where applicable; use tokens for state-changing operations.
- Audit logs: capture user actions (login, create, update, delete) with timestamps and IP addresses for accountability.
7. Performance Tuning
- Enable pagination for large lists and use server-side sorting and filtering to avoid heavy DOM loads.
- Use asynchronous loading for non-critical assets (defer or async attributes on scripts).
- Minify and bundle CSS/JS to reduce request count and payload size. Use gzip or Brotli compression at the web server level.
- Monitor application performance with server logs and database slow query logs; optimize queries and add indexes accordingly.
8. Custom UI / Theming
- Start with a base theme and implement a design token approach (variables for colors, spacing, fonts) to make global changes easy.
- Override specific page templates cautiously; prefer CSS tweaks over rewriting generated HTML to maintain compatibility with future regenerations.
- For multi-tenant or branded deployments, implement runtime theme switching by loading different CSS variables or stylesheets based on tenant settings.
9. Integrations and APIs
- Expose business-critical functions as RESTful endpoints or use ASPRunner’s API features to allow other systems to interact with your app.
- Rate-limit and authenticate API endpoints with API keys or OAuth where needed. Log API usage for troubleshooting.
- For webhook integrations, implement a retry/backoff mechanism for failed deliveries and verify payloads using signatures.
10. Testing, Deployment & CI/CD
- Automate builds with a CI/CD pipeline that exports ASPRunner project files, runs tests, and deploys generated code to staging/production.
- Create end-to-end tests for critical flows (login, create/edit/delete records) with tools like Playwright or Cypress.
- Use database migration tools (Flyway, Liquibase) to version schema changes alongside the ASPRunner project.
- Maintain separate environments: dev, staging, prod. Use feature flags for safely toggling new functionality.
11. Troubleshooting Common Issues
- “Slow list pages”: check for missing indexes, excessive joins, or large lookup loads. Enable SQL profiling to find slow queries.
- “Unexpected permissions”: audit role settings and inherited permissions on pages and fields. Check server events that may mask or override behavior.
- “Custom code lost after regeneration”: keep custom code in separate include files or use event handlers that persist; avoid editing generated core files directly.
12. Useful Advanced Features & Hacks
- Use SQL views as virtual tables to present denormalized or aggregated data without changing the database.
- Leverage database-specific functions (window functions, JSON columns) to simplify server logic and improve performance.
- Implement soft deletes (is_deleted flag) and global filters to allow recovery of records and safer data removal.
- For large-scale deployments, consider read replicas for reporting pages and configure the app to direct read-only queries to replicas.
13. Learning Resources & Community Tips
- Follow the ASPRunner changelog and release notes to track new features and breaking changes.
- Browse community forums for shared snippets, templates, and event handlers. Contribute useful patterns back to the community.
- Build a small library of reusable components (JS helpers, CSS utilities, server event templates) to speed up new projects.
Conclusion
