Golang Language Standards

Priority: P0 (CRITICAL)

Guidelines

• •Fmt: Run gofmt or goimports on save.
• •Naming: Use camelCase for internal, PascalCase for exported.
• •Packages: Short, lowercase, singular, no underscores (e.g., net/http not net_http).
• •Interfaces: Define where used, not where implemented. Small interfaces (1-2 methods).
• •Errors: Return error as last return value. Handle immediately.
• •Variables: Short names for small scope (i, ctx), descriptive for large scope.
• •Slices: Prefer slices over arrays. Use make() for capacity.
• •Const: Use iota for enums.

Anti-Patterns

• •No init: Use constructors, not init().
• •No Globals: Use DI, not global mutable state.
• •No panic: Return errors, don't panic.
• •No _ ignored errors: Always check and handle errors.
• •No stutter: log.Error, not log.LogError.
