Under the Hood: How Blaze Speeds Up Blade Templates

Blaze is a high-performance Blade compiler from the Livewire team that speeds up Laravel template rendering by shifting work from runtime to compile time. It uses three strategies: constant folding (inlining static component HTML at compile time), function compilation (replacing Laravel's heavy ComponentAttributeBag boilerplate with a simple require_once + function call), and memoization. The post walks through building two toy implementations—Smol Blaze and Lil Blaze—from scratch, covering tokenization, AST parsing, folding with static attribute detection, and wrapping components as standalone PHP functions. This gives a concrete mental model of how Blaze eliminates the verbose runtime overhead of standard Blade component rendering.
