LanguageProject Introduction
Summary
Templ provides a dedicated syntax and compiler for defining HTML templates directly within your Go project. It generates highly performant Go code functions that output HTML, ensuring type correctness and catching errors during compilation rather than at runtime.
Problem Solved
Traditional HTML templating in Go often relies on runtime parsing and execution, lacking compile-time checks and potentially impacting performance. Hand-writing complex HTML structures in Go code can be verbose and error-prone. Templ addresses these issues by offering a type-safe, performant, and developer-friendly approach to building web UIs in Go.
Core Features
Compile-time Type Safety
Templates are compiled to Go code, leveraging Go's type system to catch errors like incorrect variable usage or function calls before your application runs.
High Performance
Generated Go code is significantly faster than many runtime-interpreted templating engines, leading to better server response times.
Seamless Go Integration
Templ components compile into standard Go functions that can be easily integrated with standard library HTTP handlers or popular Go web frameworks.
