htr

Fast html to react jsx transformer

Getting Started

This project transforms html into react jsx markup.

This helps when using find and replace tools when you scrape content getting raw html and need a way to convert it back to the form it would be in a valid React codebase.

[dependencies]
htr = "0.5.26"

extern crate htr;
use htr::convert_props_react;

fn main(){
    let html = r#"<div class="something" for="mystuff" tabindex="2" style="color: white; background-color: black">"#;
    let react_html = convert_props_react(html.to_string());

    println!("{}", react_html);
    // <div className="something" htmlFor="mystuff" tabIndex="2" style={{color: "white", backgroundColor: "black"}}>
}

extern crate htr;
use htr::convert_to_react;

/// convert html to react component
fn main(){
    let html = r#"
        <script>window.alert()</script>
        <div class="something" for="mystuff" tabindex="2" style="color: white; background-color: black">
            <div class="child" for="mychildstuff" tabindex="2">
                child
            </div>
        </div>
        <span class="react" style="position: relative; display: block; margin-left: auto; margin-right: auto; max-width: 577px; "
        ></span>
        "#;

    let react_component = convert_to_react(&html.to_string(), "Something");

    println!("{}", react_component);
    // import React from "react"
    //
    // function Something() {
    //     return (
    //        <>
    //            <script>{`window.alert()`}</script>
    //                <div className="something" htmlFor="mystuff" tabIndex="2" style={{color: "white", backgroundColor: "black"}}>
    //                  <div className="child" htmlFor="mychildstuff" tabIndex="2">
    //                      child
    //                  </div>
    //              </div>
    //              <span className="react" style={{position: "relative", display: "block", marginLeft: "auto", marginRight: "auto", maxWidth: "577px"}}
    //              ></span>
    //        </>
    //     )
    // }
}

About

This project uses BTrees and parses the html with the order sorted before lookup for speed.

An example of this being used with ripgrep to perform search and replace from scraped content to find exactly where in the codebase it would be, the react way.

TODO

1. inline symbols handling ex: <div>{</div>
