Use Haxe #if directives and -D flags to exclude platform-specific code from builds where it does not apply, with verification steps for JavaScript and C++ targets.
Haxe accepts any object that matches a function’s required field shape at compile time, ignoring extra properties and rejecting missing required fields. Here’s how the matching works and what to watch out for.
Use Haxe conditional compilation to isolate platform-specific APIs behind a stable interface, with compile-time removal via -D flags, clear build checks, and limits on use to avoid hidden type errors.
Learn how a simple compile‑time macro can generate getters, setters and equality methods for plain data classes, reducing boilerplate while keeping builds fast.
Learn how Haxe’s @:genericBuild macro can generate toJson/fromJson methods for any struct, removing boilerplate and runtime reflection while staying cross‑target.
Haxe abstract types let you wrap primitives with domain-specific rules at compile time. Learn how @:forward, operator overloading, and implicit casts improve type safety across targets.
Learn when to use Haxe Abstracts versus Classes to eliminate primitive obsession and reduce runtime memory overhead in domain-driven designs.
Learn how Haxe’s #if/#else directives let you write platform‑specific code while keeping a single source file, with a concrete file‑system wrapper example and practical checks.
A guide to designing and maintaining Haxe macros, focusing on AST transformation, trust boundaries, and avoiding compiler-side side effects.
