WebForms Core Technology in Rust, Ruby, Swift, GO, R, Elixir

#go #rust #ruby #swift

This article is a continuation of the previous article. In the previous article, we explained the WebForms Core technology completely, please read the previous article completely before reading this article.

You can see the previous article in the link below:
https://dev.to/elanatframework/webforms-core-technology-in-python-php-java-nodejs--2i65

Currently, WebForms Core technology is available in 6 programming languages ​​including Rust, Ruby, Swift, GO, R and Elixir.

Rust (Actix-web framework)

To use WebForms Core, first copy the WebForms class file in below link to your project. Then create a new View file similar to the one below.

Rust WebForms class link:
https://github.com/elanatframework/Web_forms_classes/blob/elanat_framework/rust/WebForms.rs

View file

use actix_web::{web, App, HttpResponse, HttpServer, Responder};
use actix_web::middleware::Logger;

#[derive(Debug, Deserialize)]
struct FormData {
    txt_name: String,
    txt_backgroundcolor: String,
    txt_fontsize: i32,
    btn_setbodyvalue: Option<String>,
}

async fn index() -> HttpResponse {
    let html = r#"
    <!DOCTYPE html>
    <html>
    <head>
      <title>Using WebForms Core</title>
      <script type="text/javascript" src="/script/web-forms.js"></script>
    </head>
    <body>
        <form method="post" action="/submit" >
            <label for="txt_Name">Your Name</label>
            <input name="txt_Name" id="txt_Name" type="text" />
            <br>
            <label for="txt_FontSize">Set Font Size</label>
            <input name="txt_FontSize" id="txt_FontSize" type="number" value="16" min="10" max="36" />
            <br>
            <label for="txt_BackgroundColor">Set Background Color</label>
            <input name="txt_BackgroundColor" id="txt_BackgroundColor" type="text" />
            <br>
            <input name="btn_SetBodyValue" type="submit" value="Click to send data" />
        </form>
    <body>
    </html>
    "#;

    HttpResponse::Ok()
       .content_type("text/html")
       .body(html)
}

async fn submit_form(form: web::Form<FormData>, web_form: web::Data<WebForms>) -> impl Responder {
    let name = &form.txt_name;
    let background_color = &form.txt_backgroundcolor;
    let font_size = form.txt_fontsize;

    web_form.set_font_size(InputPlace::tag("form"), font_size);
    web_form.set_background_color(InputPlace::tag("form"), background_color.clone());
    web_form.set_disabled(InputPlace::name("btn_SetBodyValue"), true);
    web_form.add_tag(InputPlace::tag("form"), "h3");
    web_form.set_text(InputPlace::tag("h3"), format!("Welcome {}!", name));

    HttpResponse::Ok().body(web_form.response())
}

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    let web_form = WebForms::new();

    HttpServer::new(move || {
        App::new()
            .app_data(web::Data::new(web_form.clone()))
            .wrap(Logger::default())
            .route("/", web::get().to(index))
            .route("/submit", web::post().to(submit_form))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

In the upper part of the View file, it is first checked whether the submit button has been clicked or not, if it has been clicked, an instance of the WebForms class is created, then the WebForms methods are called, and then the response method is printed on the screen, and other parts Views are not displayed. Please note that if the submit button is not clicked (initial request), the view page will be displayed completely for the requester.

As you can see, the WebFormsJS script has been added in the header section of the View file above.

The latest version of the WebFormsJS script is available through the link below:
https://github.com/elanatframework/Web_forms/blob/elanat_framework/web-forms.js

Ruby (Sinatra framework)

To use WebForms Core, first copy the WebForms class file in below link to your project. Then create a new View file similar to the one below.

Ruby WebForms class link:
https://github.com/elanatframework/Web_forms_classes/blob/elanat_framework/ruby/WebForms.rb

View file

require 'sinatra'
require_relative 'WebForms'

post '/' do
  if params['btn_SetBodyValue']
    name = params['txt_Name']
    background_color = params['txt_BackgroundColor']
    font_size = params['txt_FontSize'].to_i

    form = WebForms.new

    form.set_font_size(InputPlace.tag('form'), font_size)
    form.set_background_color(InputPlace.tag('form'), background_color)
    form.set_disabled(InputPlace.name('btn_SetBodyValue'), true)

    form.add_tag(InputPlace.tag('form'), 'h3')
    form.set_text(InputPlace.tag('h3'), "Welcome #{name}!")

    return form.response
  end

  erb :form
end
