JavaScript Transpiler Configuration Scope Visualizer
Overview
A clean, professional, browser-based tool designed to help developers visualize the resolution scope of JS transpilation configuration files (specifically targeting the logic behind .babelrc vs babel.config.json style resolution).
Core Features
- Virtual File System: A drag-and-drop or clickable UI to build a mock directory structure.
- Configuration Placement: Add virtual
config.jsonfiles at any level of the tree. - Resolution Logic Engine: A logic layer that calculates which configuration file applies to a selected file based on standard transpiler resolution rules.
- Interactive Visualizer: Color-coded tree branches showing which files are "touched" by which configuration.
- Conflict Highlighter: Alerts users when a file is potentially affected by multiple configuration files or none at all.
UI Layout
- Header: Simple, minimal title with a "Reset Simulation" button.
- Main Content (Two-Column Layout):
- Left Sidebar (Tree Controls): Add folders/files, place configuration files, and manage the hierarchy.
- Right Canvas (Resolution Visualizer): A dynamic tree rendering that updates in real-time as the hierarchy changes.
- Footer/Results Panel: An "Active Configuration" card that shows the final JSON/Settings applied to the currently selected file in the tree.
Design & Aesthetics
- Style: Clean SaaS aesthetic. Use soft shadows (
box-shadow: 0 4px 6px -1px rgb(0 0 0 / 0.1)), rounded corners (border-radius: 8px), and a generous amount of whitespace. - Color Palette:
- Background:
#f8fafc(Slate 50) - Primary Brand/Action:
#3b82f6(Blue 500) - File Icons/Text:
#1e293b(Slate 800) - Border/Inactive:
#e2e8f0(Slate 200)
- Background:
- Transitions: All UI interactions (opening folders, selecting files) must use CSS
transition: all 0.2s ease-in-outfor a smooth, high-fidelity feel.
Developer Directives
- Architecture: Single file (HTML/CSS/JS). Use Tailwind CSS via CDN for styling.
- State Management: Use a simple JavaScript object as the single source of truth for the file structure. No external storage (no localStorage, no cookies).
- Performance: Use event delegation for the tree view to ensure the app remains snappy even with deep file structures.
- Compatibility: Ensure the app works perfectly inside a
nullorigin iframe. All external links must betarget="_blank" rel="noopener noreferrer". - Modals: If interaction is required (e.g., renaming a file), use an absolute-positioned
divcentered on screen rather thanprompt()oralert().

Frequently Asked Questions
Everything you need to know about using this application.
What is the difference between file-relative and project-wide configurations?
File-relative configurations are applied only to the specific file or folder where the configuration file is located. This allows for granular control over different parts of your codebase, but can lead to configuration fragmentation if not managed correctly in complex monorepos. Project-wide configurations, on the other hand, apply to the entire project directory regardless of where the files are located. These are typically used to enforce consistent transpilation rules across all source files, ensuring that your build pipeline remains predictable and uniform.
Why does my JavaScript transpilation config not apply to my files?
If your configuration is not applying, you may have a mismatch between the configuration scope and the file path. For example, if you are using a file-relative configuration, the file must be physically located within the same directory as the config file; otherwise, the transpiler will ignore it. Alternatively, you might be using a project-wide configuration in a location that the transpiler does not expect. Our visualizer tool allows you to map out your directory structure and test how specific configuration files interact with individual source files to identify these scope-related conflicts quickly.
Does this tool save my project configuration files?
No, this application runs entirely within your browser's memory and does not save, store, or transmit your data to any external server. We respect your privacy and security by ensuring that all simulations happen locally on your device. Because we do not use local storage, cookies, or databases, all your input data will be cleared if you refresh the browser page. This design ensures that you can use the tool safely without worrying about sensitive project information being logged or persisted.
How can I debug complex transpiler configurations in a monorepo?
Debugging complex monorepo configurations requires a clear understanding of the resolution hierarchy. By using our visualizer to replicate your directory structure, you can simulate which configuration file wins when multiple files are present at different depths of the folder tree. Simply add your virtual folders, place your configuration files, and define your test files within the visualizer. You will immediately see which rules apply to each file, helping you resolve shadowing issues or incorrect inheritance paths without needing to run your full build script.
