HypertextTemplates.jl

HTML templating system for Julia

HypertextTemplates.jl provides a Julian approach to writing HTML using macros that feel natural within the language. Build web pages using Julia's control flow, components, and type safety—all with zero-allocation rendering for maximum performance.

Features

• Native Julia syntax - Write HTML using macros that integrate seamlessly with Julia's control flow
• Component system - Create reusable components with props and slots
• Context system - Pass data through component trees without prop drilling using @context and @get_context
• Zero-allocation rendering - Direct IO streaming without intermediate DOM construction
• Automatic HTML escaping - Secure by default with automatic escaping, use SafeString for trusted content
• Development tools - Source location tracking and editor integration for debugging
• Streaming rendering - Asynchronous rendering with micro-batched output
• Markdown integration - Create components from Markdown files with interpolation support

Quick Example

using HypertextTemplates
using HypertextTemplates.Elements

# Define a reusable component
@component function article_card(; title, author, content)
    @article {class = "card"} begin
        @header begin
            @h1 $title
            @p {class = "author"} "by " $author
        end
        @div {class = "content"} $content
    end
end
@deftag macro article_card end

# Render HTML
html = @render @div {class = "container"} begin
    @article_card {
        title = "Hello, HypertextTemplates!",
        author = "Julia Developer",
        content = "Building web content with Julia is fast and elegant."
    }
end
