Lua Basics

Best practices for writing effective Lua code in FiveM. This skill covers fundamental Lua patterns, performance optimizations, and code quality guidelines specifically for FiveM development.

When to use

• Writing or reviewing Lua code for FiveM resources.
• Questions about Lua best practices, naming conventions, or code structure.
• Optimizing Lua code for performance.
• Need guidance on functions, tables, variables, conditionals, or error handling in Lua.

How to use

Read individual rule files for detailed explanations and examples:

• rules/functions.md — Function best practices: size, naming, parameters, exports, guard clauses.
• rules/tables.md — Table operations: array indices, dereferencing, avoiding table.insert, iterations, array size.
• rules/variables.md — Variable naming conventions: constants, locals, globals, enums vs booleans.
• rules/conditionals.md — Conditional patterns: default values, boolean expressions, readability.
• rules/errors.md — Error handling: assertions, pre-conditions, errors as values, fail loudly.
• rules/reference-links.md — Official Lua and FiveM documentation resources.
