thenewcoderss/pdf-parser

This repository is a very small, browser-based demo application for PDF parsing. The visible surface consists of a single HTML page and a single JavaScript file, with no backend, build system, or package manifest present in the file tree.

The architecture is likely a classic static frontend split:

• index.html is the page shell and browser entry point.

• app.js contains the actual application logic, including whatever PDF-loading and parsing behavior the demo implements.

• README.md only provides the project label: “Demo pdf parser.”

The runtime boundary is the browser. There is no evidence of a server-side component, API layer, database, or worker service in the repository as shown. For an architecture diagram, this should be treated as a self-contained client-side demo rather than a multi-tier system.

The main functional subsystem is the PDF parser itself, which would be represented as the core logic inside app.js. Because there are no additional source files, any parsing, validation, or result transformation is probably centralized in that one script rather than split into services or modules.

index.html likely acts as the presentation and interaction layer: it provides the DOM container(s), input controls, and output region that app.js manipulates. In a diagram, this is the user-facing boundary between the browser and the app logic.

The data flow is probably straightforward:

1. User interacts with the page in index.html.

2. app.js receives the input event or file/content source.

3. The script parses PDF data in-browser.

4. Parsed output is rendered back into the page.

There is no visible persistence layer. Any parsed results are likely transient and kept in memory or displayed directly in the DOM. Likewise, there is no obvious external storage, authentication, or multi-user coordination boundary.

There is also no visible dependency-management or tooling layer. That suggests either plain vanilla JavaScript or dependencies loaded externally from the HTML, but nothing in the tree confirms a bundled or framework-based setup.

For an architecture diagram, the safest representation is:

• External actor: user in browser

• Presentation shell: index.html

• Application/parse logic: app.js

• Output: rendered parsed PDF data back in the browser

If you want to show boundaries, keep them coarse: “browser UI” and “client-side parsing logic.” Do not introduce backend or infrastructure boxes, since the repository snapshot does not support them.
