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.
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 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.
Haxe's #if directives strip code before type checking, making them ideal for dependency management but risky for divergent logic. Learn where conditional compilation fits and when to use target-specific classes instead.
Learn how to use Haxe’s #if directives and -D flags to keep one codebase that compiles cleanly for JS, HXCPP, and other targets. Follow a step‑by‑step guide to set up flags, write platform‑specific blocks, verify builds, and avoid common pitfalls.
Haxe compiles one codebase to many targets, but platform APIs differ. Learn when to use #if conditionals, custom -D flags, or separate modules—and how to verify each build.
Use Haxe’s #if directives to prune platform‑specific code, eliminating dead code and runtime checks. A concrete logger example shows how to compile clean outputs for JS, C++, and other targets.
Use Haxe conditional compilation as a compile-time seam for platform differences, not as general branching. Isolate JS and C++ APIs behind small abstractions, keep flags in one place, and verify generated output is stripped per target.
Use Haxe's #if directives to keep platform-specific code out of the wrong target's build — with a worked Storage example and the pitfalls to watch.
