Features

Authentication and layout

• Authentication: log in via any OIDC compliant Solid identity provider (solidcommunity.net, inrupt.net, solidweb.org, or a self hosted server)

• Layout choice: switch at runtime between the classic two pane shell and the OneDrive style shell; the preference is persisted in localStorage

• Language switching: switch between English and German at runtime

Navigation

• OneDrive views: Home / Recent, My Files, Shared, Requests, and People; each view has its own toolbar, type filter chips, and a person and name filter; the Shared view has With you and By you tabs

• Pod navigation: browse the full Pod directory tree with breadcrumb navigation; per folder scroll position is preserved across browser back and forward

• URLs and history: the open folder is reflected in the query string (folder=…) and the active OneDrive view in view=…; copy the address bar to share a deep link, and use the browser back/forward buttons to move through your navigation history

Files

• File upload: accepts any file type. Users can upload through the dialog form, by dragging files onto the panel or a folder row, or from the OneDrive Create menu. The binary and a metadata document index.ttl are stored inside a dedicated container on the Pod, and an upload tray surfaces progress and per file retry.

• Folder creation: the classic explorer uses an inline form, and the OneDrive shell opens a modal dialog. Both create LDP BasicContainers under the active folder.

• File adoption: renders files that existed on the Pod before the app was used, showing folder name and download button for containers lacking index.ttl

• Inline preview: images, videos, audio, PDFs, and text files preview directly in the browser, no request leaves the browser after the file is fetched

• Download: triggers a browser native download from the blob URL

• File info: a toggle on each file card shows type, size, upload date, modified date, and publisher name resolved from their Solid profile

• Selection actions: the OneDrive shell shows Share, Copy link, Delete, and Download in the page header, plus Move to and Rename stubs. Actions that no longer fit inline spill into a kebab dropdown at narrow viewports.

• Delete: removes the binary, index.ttl, the container, and the catalog entry; no orphaned resources remain

Linked data

• TBox-driven validation: SHACL shapes are loaded from public/tbox.ttl at form open time; required fields (name, uploadDate, publisher) are enforced before upload; missing fields are surfaced inline

• Semantic classification: MIME type is mapped to a schema.org class and written to index.ttl as rdf:type

• Catalog management: catalog.ttl is updated on every upload and cleaned up on every delete using SPARQL PATCH

Sharing

• Share / revoke access: each owned file can be shared with contacts from the user’s Solid profile; ACLs and per contact shared catalogs are kept in sync

• Shared with Me: reads per contact shared catalogs first, then falls back to the contact’s main catalog

• Filtered system files: internal catalog and ACL helper files (.shared-*.ttl) are hidden from the normal file browser

Getting Started

Prerequisites

• Node.js 20.x or later

Installation

git clone {github-repository}.git
cd Solid-Hello-World-Frontend-React
npm install

Usage

Development

npm run dev           # extract TBox and start dev server at http://localhost:5173

Testing

npm test              # unit tests once
npm run test:watch    # unit tests in watch mode
npm run test:coverage # unit tests with v8 coverage
npm run test:e2e      # Playwright end-to-end tests
npm run test:e2e:ui   # Playwright interactive UI mode

Production build

npm run build         # extract TBox, type check, and bundle
npm run preview       # serve the built bundle locally

Regenerating derived files

npm run tbox:extract  # refetch datashapes.org and rewrite public/tbox.ttl
npm run build:ldo     # recompile ShEx shapes -> TypeScript bindings in src/.ldo/

ℹ️	npm run dev and npm run build run tbox:extract automatically. Use the manual commands only after editing .shapes/ files or when the upstream ontology changes.

Docker

Run the published image:

docker run -p 40211:80 wseresearch/solid-hello-world-frontend-react

Or build and run locally:

docker build -t wseresearch/solid-hello-world-frontend-react:local .
docker run -p 40211:80 wseresearch/solid-hello-world-frontend-react:local

The app listens on port 80 inside the container; open http://localhost:5173/ in your browser.

How it works

Pod layout

Each uploaded file gets a dedicated container on the Pod. A DCAT catalog at the storage root keeps a queryable index:

Pod storage root/
|-- catalog.ttl                  <- DCAT catalog: one entry per file
`-- my-solid-app/
    |-- .shared-<webid>.ttl      <- per-contact shared catalog
    `-- photo-2024-01-01/        <- one container per uploaded file
        |-- photo.jpg            <- the binary
        `-- index.ttl            <- schema.org metadata

Upload sequence

pick file
  -> validate metadata against SHACL shapes (tbox.ttl)
    -> resolve schema.org class from MIME type
      -> create container
        -> upload binary
          -> write index.ttl
            -> append dcat:Dataset entry to catalog.ttl
              -> link catalog to WebID profile (first upload only)

ℹ️	If any step after the binary upload fails, the whole container is deleted, no half written resources are left on the Pod.

Sharing

Sharing happens at the file container level. Granting access updates the file’s ACL and mirrors its catalog entry into a per contact shared catalog inside my-solid-app/. Revoking removes the recipient from the ACL and cleans up their shared catalog entry.

Semantic classification

MIME types are mapped to schema.org classes:

image/*

schema:ImageObject

video/*

schema:VideoObject

audio/*

schema:AudioObject

text/*, application/pdf, Word

schema:TextDigitalDocument

CSV, Excel

schema:SpreadsheetDigitalDocument

Anything else

schema:DigitalDocument

Known issues

• inrupt.net blocks localhost redirects. The inrupt.net identity provider rejects OIDC redirect URIs pointing to localhost. Use solidcommunity.net or solidweb.org when testing locally.
