Migrating from SA-MP to JSAMP: What You Need to Know

Top 7 JSAMP Tips and Best Practices for Developers

1. Understand the architecture

Clarity: JSAMP wraps SA-MP client/server functionality in JavaScript. Learn the event flow (server callbacks → client events → timers) and how JSAMP exposes native APIs so you avoid race conditions and misuse of resources.

2. Use asynchronous patterns properly

Tip: Prefer async/await and Promises for I/O, database calls, and any long-running tasks. Blocking the main event loop with synchronous operations will degrade server responsiveness.

3. Keep resource usage minimal

Tip: Limit per-player timers and avoid spawning heavy loops. Reuse data structures (maps/sets) instead of recreating them per tick. Track memory growth during load testing.

4. Structure code modularly

Best practice: Split features into modules (commands, vehicles, economy, permissions). Export clear APIs between modules and avoid global mutable state. Use a central module for shared services (DB, logger, config).

5. Sanitize and validate all input

Tip: Treat any client-provided value as untrusted. Validate command arguments, player-sent data, and database results. Use whitelists for expected values and enforce type checks.

6. Optimize event handlers

Tip: Only bind events you need; deregister when not required. Batch updates for frequent events (e.g., position sync) and debounce/Throttle handlers where appropriate to reduce CPU spikes.

7. Implement robust logging and error handling

Best practice: Centralize logging with levels (debug/info/warn/error). Catch and log errors in async handlers and use fail-safes for critical operations (e.g., revert partial transactions). Monitor logs and set alerts for repeated or high-severity errors.

Quick checklist

• Use async/await for async tasks
• Avoid per-player heavy timers
• Keep modules single-responsibility
• Validate all inputs and commands
• Deregister unused event listeners
• Centralize logging and error handling
