PPTX / DOCX → HTML converter (proprietary). One package; Free vs Licensed is selected by a signed .lic at runtime, or use Cloud for remote conversion.
| Mode | How | Behavior |
|---|---|---|
| auto (default) | Omit --mode, or --mode auto |
Valid local .lic → same as license; otherwise free |
| free | --mode free |
Force Free local (Community degradations) |
| license | --mode license (requires valid .lic) |
Full local engine (alias: licensed) |
| cloud | --mode cloud |
Remote Licensed conversion via DeckFlow Cloud |
npm install @deckflow/deck2htmlDo not omit optional dependencies (--omit=optional / --no-optional); the native binary lives in a platform package such as @deckflow/deck2html-darwin-arm64.
# Free local (Community degradations when no valid license)
npx deck2html deck.pptx -o ./out
# Licensed local
npx deck2html deck.pptx -o ./out --license ~/.deckflow/deck2html.lic
# defaults also accept ~/.deckflow/deckuse.lic (first valid wins)
# or: export DECK2HTML_LICENSE=~/.deckflow/deck2html.lic
# Force Free even with a valid license
npx deck2html deck.pptx -o ./out --mode free
# Require Licensed local
npx deck2html deck.pptx -o ./out --mode license
# Cloud (full fidelity via remote Licensed worker)
npx deck2html deck.pptx -o ./out --mode cloud
# Auth for higher cloud quota (shares ~/.deckflow/credentials with html2deck)
npx deck2html auth login

spawnSync(getBinaryPath(), ['deck.pptx', '-o', './out'], { stdio: 'inherit' });| Flag / env | Meaning |
|---|---|
--license <path> |
Optional .lic → Licensed when valid (unless --mode free) |
DECK2HTML_LICENSE |
License path env |
--mode auto|free|license|cloud |

Cloud API key (optional; guest mode otherwise) |
DECK2HTML_CONFIG_DIR |
Credentials dir (default ~/.deckflow) |
--check-license |
JSON probe; exit 0 if valid (machineBound / machineId when bound) |
fingerprint |
Print 64-char hex machine id for optional single-machine .lic binding |
