This is the actual source code of the lewp crate. See the repository root for information about the framework, or visit the documentation page.

lib.rs:

Say goodbye to the web template hell. Generate your HTML5 website technically optimized and always valid. In your Rust source.

⚠ This crate is currently evolving. API changes can happen anytime until v1.0.0

Provided solutions

When using lewp, you get the following benefits during web development:

• No more template hell in your code base
• No more whitespace bugs in your website
• Technically optimized, always valid, minified, HTML5 code
• Module based development, truly isolated
• Build the DOM completely in Rust

Hello world! example

    lewp::{
        config::{ModuleConfig, PageConfig},

        Page,

        LanguageTag,
        LewpError,
    },
    std::rc::Rc,
