vortex-mod-mediafire

MediaFire WASM plugin for Vortex. Resolves free MediaFire https://www.mediafire.com/file/... links to their direct CDN URL on download<n>.mediafire.com.

Features

• Plain href extraction from the public download landing page
• data-scrambled-url (base64) decoding for the obfuscated variant — decoded URL must resolve to a download*.mediafire.com host or it is rejected (defensive against attacker-controlled scramble payloads)
• Filename + size parsing from the <span class="dl-btn-label"> label
• Falls back to the URL's filename hint and finally the path tail when the page omits an explicit label
• No wait, no captcha — the plugin returns the direct URL on first resolve

URL shapes recognised

• https://www.mediafire.com/file/<key>
• https://www.mediafire.com/file/<key>/file
• https://www.mediafire.com/file/<key>/<filename>
• https://www.mediafire.com/file/<key>/<filename>/file
• https://m.mediafire.com/file/<key>... (mobile shorthand)

Folder links (mediafire.com/folder/...) are not in scope here — folder enumeration is a crawler concern and lives in a separate plugin.

Plugin contract

The plugin exports the standard Vortex plugin contract:

Function	Input	Output
can_handle	URL string	"true" / "false"
supports_playlist	URL string	always "false"
extract_links	URL string	JSON ExtractLinksResponse
resolve_stream_url	JSON {url}	direct CDN URL string

ExtractLinksResponse mirrors the LinkStatus::Online shape used by the host's link-check pipeline: each files[] entry carries filename, size_bytes, direct_url, and resumable: true.

Build

rustup target add wasm32-wasip1
cargo build --target wasm32-wasip1 --release

Resulting WASM: target/wasm32-wasip1/release/vortex_mod_mediafire.wasm.

Install (development)

PLUGIN_DIR="$HOME/.local/share/dev.vortex.app/plugins/vortex-mod-mediafire"
mkdir -p "$PLUGIN_DIR"
cp plugin.toml "$PLUGIN_DIR/plugin.toml"
cp target/wasm32-wasip1/release/vortex_mod_mediafire.wasm \
   "$PLUGIN_DIR/vortex-mod-mediafire.wasm"

Vortex picks up the new plugin via the file watcher; no restart needed.

Tests

cargo fmt --all -- --check
cargo clippy --locked --all-targets --target x86_64-unknown-linux-gnu -- -D warnings
cargo clippy --locked --lib --target wasm32-wasip1 -- -D warnings
cargo build --locked --lib --target wasm32-wasip1 --release
cargo test --locked --all-targets --target x86_64-unknown-linux-gnu

The HTML fixtures live in tests/fixtures/*.html — ten variants covering plain href, large/small sizes, missing size text, missing filename, extra attributes, and an offline page that triggers NoDirectLink.
