The create-a-link flow only accepted pasted text, so compressing an existing file meant opening it, copying, and pasting.

This adds a client-side Load file control (and drag-and-drop) on the load-body step. The chosen file is read in the browser, fills the same draft the compressor already uses, and is never sent to the host.

  • Infers kind / filename / title / language from the file when the extension is known
  • Rejects empty, binary, and oversized files
  • Paste still works; dropped plain text still lands in the textarea

Verification

  • Unit/component tests for the file helper and creator
  • Playwright: loads a local file into the homepage link creator (chromium)
  • Full Vitest suite: 370 passed
  • Manual browser flow: choose a local markdown file → fields fill → generate link → preview the rendered artifact
  • CI on this branch is green

Summary by CodeRabbit

  • New Features

    • Load artifact content from a local text file using the file picker or drag and drop.
    • Automatically populate title, filename, content, and supported language or format fields.
    • Validate unsupported, oversized, empty, or binary files with clear error feedback.
    • Keep local file contents in the browser during draft creation.
  • Documentation

    • Updated usage and architecture documentation to describe local file loading and browser-only handling.
  • Tests

    • Added coverage for file validation, format detection, draft population, and end-to-end link creation.

The create-a-link flow could only accept pasted text. Users can now choose or drop a local text file, which is read in the browser and compressed into the same fragment link.

Rapid file selections or edits while a file is loading can replace the newer draft or show an obsolete error. Guard stale results before merging.

Summary

Adds browser-only local file loading to the homepage link creator.

  • Supports file-picker and drag-and-drop input with extension-based artifact and language inference.
  • Rejects empty, oversized, known-binary, and suspiciously decoded files.
  • Prevents older file reads from replacing a more recently selected file and uses current draft preferences when applying the result.
  • Adds component, helper, language-detection, and end-to-end coverage.
  • Updates product and architecture documentation for the new client-side flow.

Comment thread src/components/home/link-creator.tsx
A slower file.read could overwrite a newer selection, and OS pickers often label .ts as video. Sequence reads, trust known text extensions over MIME, and reject decoded control/replacement characters.
