Slide types

Deckyard ships 35 built-in slide types: 35 offered when you add a slide, and 0 retired ones that still render, because a deck that stops opening is a deck you have lost.

This page is the exhaustive field list, generated from the same registry that builds the editor form, runs validation and generates the JSON Schemas. For the same types as a visual catalogue with layout diagrams, see the slide-type spec; for a guided tour of what each one is for, see Slide Types.

Reading the tables

• Key is the property name inside a slide’s content object.
• Required means the importer will not blank it; an absent or empty value falls back to the type default.
• Limit is the maximum length in characters, where the type declares one.
• Options lists the accepted values of an enumerated field.
• Every type also accepts the global fields below.

The line under each heading carries what the type declares about itself, none of which is part of its JSON Schema - the schema describes a slide’s content, and these are statements about the type:

• Tier is how far our promise goes. Tier 1 is the normative core profile a conforming implementation renders; tier 2 we ship and publish, but it versions with the app.
• Structure is the shape of the primary content, and it is the axis worth building a reader against: six values cover every type.
• Runtime is what the presenting session has to do beyond serving the slide (static - nothing, timed - a presenter-driven clock, live - the audience answers and the session aggregates), with the kind of answer a live type collects in brackets.
• Falls back to is the tier-1 contract to degrade to when you have not implemented the type. Every tier-2 type declares one, which is why a reader that knows only the nine still renders every deck without dropping content.

All four are readable from GET /api/slide-types on any instance, and the argument behind them is on the conformance page.

Each type’s JSON Schema is served at https://deckyard.eu/schema/v15/slide-types/<type>.schema.json — see JSON Schemas for how to fetch it.

Fields every type carries

The 9 accessibility, background and logo fields below are added to every slide type rather than declared on each one. They are listed here once instead of 35 times.
