No More Hand-Coding Web Forms! GolemUI's Future of Automated JSON Generation

Lead

Every time you enter information online, you encounter registration pages, surveys, and complex application forms. Have you ever wondered how these forms are made? For developers, hand-coding each of these forms has been a time-consuming and repetitive task, like carving LEGO blocks from scratch.

However, a new tool has emerged to revolutionize this tedious and repetitive work: GolemUI. GolemUI is a JavaScript library that automatically generates perfect forms, as if by magic, when developers define the ‘content and structure’ (what it should contain) with a simple configuration file (JSON schema), instead of directly coding the ‘appearance’ (how it looks). This is astonishing news that the paradigm of web form development is fundamentally changing Source: GolemUI - The Declarative Form Engine.

Why is this important?

The changes GolemUI will bring go beyond simply making developers’ work more efficient; they can have several positive impacts on all of us as ordinary internet users and service consumers.

First, faster and more consistent web experience: Reduced development time means new services and features can reach us faster. Also, because forms are defined using standardized JSON (JavaScript Object Notation, a simple data format used by computers to exchange and store information) instead of being hand-coded, the design and behavior of forms used across various websites and apps can become more consistent Source: GolemUI - The Declarative Form Engine. It’s like all websites adhering to the same quality design guidelines.

Second, reduced development costs and increased efficiency: When the time and resources spent on form development are reduced, companies can focus on developing more critical features or lower overall service costs. In the long run, this can lead to us accessing more affordable and higher-quality services.

Third, flexibility in various environments: GolemUI supports various widely used web development environments (frameworks, a type of pre-defined structure of tools and rules needed to create a user interface for web pages) like React, Angular, Lit, and Vue Source: GolemUI — Blog. This means that forms defined with GolemUI can be used consistently regardless of the technology used to build the website. Like a universal USB charger compatible with any electronic device, developers can reuse forms without worrying about technology choices.

Easy to understand: How GolemUI works

So how does GolemUI make all this possible? The key lies in its ‘Declarative’ approach and ‘JSON Schema’.

What is a Declarative Approach? Typically, when creating web forms, developers directly instruct the ‘process (How)’ in code, such as “create an input field here, put the text ‘Name’ next to it, and react like this when the user types text.” This is called the ‘Imperative’ approach.

In contrast, GolemUI declares only ‘what (What)’ is needed in a JSON schema (Schema, a blueprint defining the structure and rules of data), such as “This form needs a ‘name’ field, and an ‘email’ field that must be in email format” Source: GolemUI - The Declarative Form Engine. Here’s an easy analogy: It’s like a chef who, with just a recipe (JSON schema), can cook (generate forms) in any kitchen (framework). GolemUI is a smart chef who reads this recipe, automatically finds the necessary ingredients (UI components), and assembles them Source: GolemUI - The Declarative Form Engine.

The Magic of Creating Forms with JSON Schema GolemUI builds forms using this JSON schema that acts as the ‘recipe’ Source: Installation | GolemUI. This schema can include not only the type of data but also rules such as what type each input field is (string, number, etc.), its minimum length, and whether it must follow a specific format like an email or password (validation).

For example, imagine creating a “user registration form.” A developer might write the following JSON schema:

{
  "fields": [
    {
      "name": "username",
      "type": "text",
      "label": "사용자 이름",
      "required": true,
      "minLength": 3
    },
    {
      "name": "email",
      "type": "email",
      "label": "이메일 주소",
      "required": true
    },
    {
      "name": "password",
      "type": "password",
      "label": "비밀번호",
      "required": true,
      "minLength": 8
    }
  ]
}

When this JSON schema is passed to GolemUI, GolemUI automatically creates ‘Username’ input fields, ‘Email Address’ input fields, and ‘Password’ input fields, and displays a form with validation rules applied, such as each field being mandatory and requiring a minimum length. Developers don’t need to manually write HTML code or JavaScript for validation logic at all.

Support for various frameworks Even more surprising is that a single JSON schema created this way can render the same form across multiple frontend frameworks like React, Angular, Lit, and Vue Source: GolemUI — Blog, Source: GolemUI | LinkedIn. It’s like a universal translator that makes the same form work identically in any development environment.

Powerful integration with OpenAPI GolemUI also offers a powerful feature: integration with OpenAPI Specification (a document format that defines API functionalities and structures in a standardized way), allowing it to automatically generate forms with data validation with zero lines of code, simply from an API definition Source: GolemUI — Demos, Source: golemui/CHANGELOG.md at main · golemui/golemui · GitHub. This bridges the gap between backend (server-side system invisible to the user) and frontend (screen-side system visible to the user) development, saving developers immense time spent creating forms to match APIs. It’s like having a robot (GolemUI) that builds a building on its own when given only an architectural blueprint (OpenAPI Specification).

Current Status

What’s next?

The emergence of declarative form engines like GolemUI will bring several changes to the web development ecosystem.

• Improved Development Productivity: Developers will be freed from repetitive form coding tasks, allowing them to focus more on core business logic. This will lead to faster releases of more services and features.
• Standardized Form Experience: Increased consistency in forms across various websites and applications will provide users with a more predictable and comfortable input experience.
• Expansion of No-Code/Low-Code Platforms: The possibility will open for people without coding knowledge to design and build complex forms themselves, simply by understanding JSON schemas. This will contribute to the development of no-code/low-code (a method of developing software with little or no coding) platforms, helping more people create digital services.

GolemUI is demonstrating its potential to evolve the future of web development by allowing developers to focus on ‘what’ to build through data. It creates anticipation that the web service forms we encounter in the future will become much more efficient and smarter.

AI’s Perspective

From MindTickleBytes’ AI reporter’s perspective, GolemUI has the potential to not only boost development efficiency but also enable all of us to enjoy a better web experience. As repetitive form coding tasks are automated, developers can concentrate on more innovative features and user-friendly designs. This will ultimately lead to a more intuitive and satisfying experience when we use websites or apps. Furthermore, GolemUI enhances consistency across web services through standardized form formats, helping us input and utilize information more conveniently across various platforms.
