dataobject
  • aggregate: object — summarise in the database: one record per group with its measures; sort by a group or measure name
  • as: string — identifiers use letters, digits and '_' and do not start with a digit
  • cache: duration (500ms, 6s…) — durations look like 500ms, 30s, 5m, 1h or 7d
  • columns: array of string
  • filter: object {name: string | number | boolean | null | object}
  • include: object {name: object} — related records loaded with each record, one query per include: {"category": {}} or {"reviews": {"source": "DATABASE.reviews", "on": "product"}}
  • items: array of any — inline records for STATIC sources
  • limit: integer (1–500)
  • live: boolean — re-render when the underlying records change (server push)
  • mode: "list" | "single"
  • paginate: object
  • query: object {name: string | number | boolean | null | object} — API sources: query values passed to the api (literals or {param|query|props} references)
  • refresh: duration (500ms, 6s…) — durations look like 500ms, 30s, 5m, 1h or 7d
  • required: boolean — page data: when nothing matches, the page answers 404
  • search: object
  • sort: object
  • source: string — sources are DATABASE.<schema>, API.<name>, STATIC, USER, STATE.<store>.<list> or an expression giving a list ("=product.images")
itemelement
emptyelement
varsobject {name: string}CSS custom properties set from data, per record: {"--accent": "=color", "--progress": "=concat(pct, '%')"}; your stylesheet uses var(--accent)

Plus the properties every element accepts: id, className, style, responsive, states, animation, visible, ariaLabel, attributes and more.

Example

container example
{
  "type": "container",
  "className": "notice",
  "style": {
    "padding": "16px",
    "borderRadius": "12px",
    "background": "var(--color-surface)"
  },
  "elements": [{ "type": "text", "variant": "label", "content": "Free delivery over ₹999" }]
}

Use container when no more specific tag (section, article through tag, header…) describes the content. Add layout for flexbox or columns for a grid; with neither it is a plain block.

Expected output

The HTML IWC rendered for the example above (inside the page's content wrapper). Class names such as i807b63fc are generated per element for its scoped CSS.

Rendered HTML
<div class="iwc-page ipage" id="iwc-content">
  <div class="iwc-container i333784bd notice">
    <span class="iwc-text icc1180bf iwc-text-label">Free delivery over ₹999</span>
  </div>
</div>

Data, conditions & styling

  • Conditional rendering: "visible": {"auth": "signed-in"}, {"roles": ["admin"]} or an expression such as "=product.stock > 0". Decided on the server: hidden elements are never sent.
  • Data binding: bind takes text from data (name, user.name, props.title, params.slug, state.cart.count); binds binds attributes. Containers become data-driven with data + item. See data binding.
  • Styling: className for your stylesheets, style for CSS in JSON, states for hover/focus/active, animation for entrance motion. See the style property reference.
  • Responsive behaviour: responsive applies CSS at or below a breakpoint ({"mobile": {"padding": "12px"}}); grids also take responsiveColumns.
