Build experimental language BayLang for web development

Ildar — Sun, 28 Dec 2025 16:08:04 +0000

Hello. I build new opensource experimental language named as BayLang.

BayLang is an architecture-oriented language and development platform. It's a programming language designed for building web applications, CRM, ERP, E-Commerce, SaaS.

The main goal is accelerate web development by use ready blocks and components such as Forms, Tables, Buttons, Input, Select and ready plugins Admin panel, Auth manager and etc.

Key idea is Clean Architecture as part of the language, not as a set of guidelines. Architectural patterns are built into the development approach itself and supported by the tools.

Core features:

Schema-driven data design, forms, APIs, and presentation are built from defined schemas
Compilation to PHP and Vue (including SPA and SSR)
Unified model for both backend and frontend
Minimal boilerplate code, maximum explicit architecture
Variable typing

Suitable for:

Enterprise and B2B systems
Admin panels and backoffice solutions
SaaS products
Systems with long lifecycles and high support costs
Projects where code readability and architectural discipline are important

BayLang is not just a new syntax - it is an attempt to formalize the best practices of enterprise development at the language and compiler level.

Example code of component:

<class name="App.Components.Pages.IndexPage.IndexPage">

<use name="Runtime.Widget.Button" component="true" />
<use name="Runtime.Widget.Section" component="true" />

<style>
.main_section{
    padding-top: 20px;
    padding-bottom: 20px;
    background-position: center top;
    background-repeat: no-repeat;
    background-size: cover;
}
</style>

<template>
    <div class="main_page">
        <Section class="main_section">
            <h1 class="page_title">Index page</h1>
            <div class="page_text">Hello {{ this.model.message }}</div>
            <Button @event:click="this.onClick()">Click</Button>
        </Section>
    </div>
</template>

<script>

/**
 * Click button
 */
void onClick()
{
    this.model.setMessage(this.model.message ~ "!");
}

</script>

</class>

Code model:

namespace App.Components.Pages.IndexPage;

use Runtime.BaseModel;
use Runtime.Serializer.MapType;
use Runtime.Serializer.StringType;
use Runtime.Web.RenderContainer;
use App.Components.Pages.IndexPage.IndexPage;


class IndexPageModel extends BaseModel
{
    string component = classof IndexPage;
    string message = "Hello World!";


    /**
     * Serialize object
     */
    static void serializer(MapType rules)
    {
        parent(rules);
        rules.addType("message", new StringType());
    }


    /**
     * Init widget
     */
    void initWidget(Dict params)
    {
        parent(params);
    }


    /**
     * Build title
     */
    void buildTitle(RenderContainer container)
    {
        this.layout.setPageTitle("Index page");
    }


    /**
     * Set message
     */
    void setMessage(string message)
    {
        this.message = message;
    }
}
