Unable to print HTML content in browser

help
1

My goal is to write complete HTML in backend and just print in front end with handlebars

pub async fn new_test(
// path: web::Path,
config: web::Data,
handlebars: web::Data<Handlebars<'_>>,
) -> Result<HttpResponse, actix_web::Error> {
let db = &config.database_connection;

let x2: String = HtmlPage::new()
    .with_title("My Page")
    .with_header(1, "Main Content:")
    .with_container(
        Container::new(ContainerType::Article)
            .with_attributes([("id", "article1")])
            .with_header_attr(2, "Hello, World", [("id", "article-head"), ("class", "header")])
            .with_paragraph("This is a simple HTML demo")
    )
    .to_html_string();

// println!("--------------------------------{:?}", html);
let x1 = r#"
<!doctype html>



Html parser


Hello world




"#;

let html = handlebars
    .render(
        "sample",
        &json!({"o":x1,"x2":x2}),
    )
    .map_err(actix_web::error::ErrorInternalServerError)?;


Ok(HttpResponse::Ok()
    .content_type(ContentType::html())
    .body(html))

}

using this code I'm unable to create the content I want

The output is this ---> The HTML tags are also printed .
I want HTML tags to be hidden and execute only contents

Why are you using handlebars if you're creating the entire HTML string elsewhere?

By default basically all HTML templating engines escape HTML content in values that are interpolated into the template to avoid allowing users to inject malicious HTML into your web page.

If you just create a response from the HTML string and set the content type to HTML, it should work without a template engine

Is it possible

The handlebars language uses triple brackets for unescaped expressions

https://handlebarsjs.com/guide/#html-escaping

According to this issue the rust crate supports this too

                            <ul class="pagination">
                                    {{#each pages_count}}

                                    <li class="page-item "><a class="page-link" href="{{this}}">
                                            {{#if (eq {{current_page}} this )}}

                                                <ul class="page-item " ><button class="page-item active">xxsdasdsssx{{this}}</button></ul>

                                                {{current_page}}
                                                {{else}}
                                                <button class="page-item">sss{{this}}</button>
                                                {{/if}}
                                    </a></li>
                                    {{/each}}
                            </ul>
                        </nav>

Here I'm unable to use If condition for two dynamic values that is current reference and curent page number to highlight the current page number

If you have any suggestion please do let me know
