# Apply Studio Development Best Practices

A consolidated reference of patterns that work and patterns to avoid. Each section is brief: anti-patterns and remedies, no narrative. Look up the relevant section when you're in the weeds, not as a read-through.

## Compositions

*   **Templates over Freeform** for content-driven pages. Use Freeform only for genuinely one-off pages; if you'd build the same Freeform composition twice, model a content type instead.
*   **Save often, deploy deliberately.** Save is a draft milestone. Deploy is a release event.
*   **One template per content type, not per content variant.** Use bindings and component variants instead of forking.
*   **Don't bypass the URL pattern editor.** Edit URLs in Studio, not directly in stack records: the editor validates and re-derives URL metadata.

## Components

*   **Eager registerComponent by default.** Use registerLazyComponent only when bundle size becomes a real concern (large component library, heavy dependencies).
*   **Register at app boot.** A registration that runs inside a route component is too late for Studio's canvas iframe.
*   **Set sensible defaultValue on every prop.** Empty defaults make dropped components render blank, authors think Studio is broken.
*   **Use placeholder copy, not real copy** for default text values. "Your headline here" is better than "Buy our amazing product today".
*   **One type value per component, never reused.** Composition records reference components by type. Renaming breaks every composition that referenced the old name.
*   **Use the right prop type.** Specifically: string (not "text"), href (not "link"), imageurl (not "image"). Studio's exact prop types are: string, boolean, number, choice, href, imageurl, datestring, array, object, slot, json\_rte, any.
*   **Prefer choice over free string for known-finite options.** size: choice \["small", "medium", "large"\] is clearer than size: string.
*   **defaultValue, not default.** The prop config field is defaultValue: a common mistake.

## Sections

*   **Anchor sections on Global Fields when possible.** Same shape everywhere, no positional remap edge cases.
*   **Use linked schemas to bind by structure, not by name.** Multi-schema sections work across content types without forking.
*   **Section Slots when authors should drop something. Exposed Props when they should change something.** Same goal (per-instance variation), different mechanisms.
*   **Sections own iteration; templates own page-level layout.** A card\_grid section owns the grid + Repeater. The template that uses it owns where in the page the grid sits.
*   **Don't fork sections for per-template-instance text overrides.** Use [Expose Section Props](/docs/studio/expose-section-props).

## Repeaters and Condition Blocks

*   **Repeater + Condition Block for Modular Block lists:** one Repeater iterating the list, one Condition Block per block type.
*   **Don't manually loop inside a component.** If your component takes an array prop and .map()s internally, you're hiding iteration from Studio's binding system. Use a Repeater instead.
*   **template.\* inside a Repeater refers to the iteration item**, not the page entry. Use dataSources.page.\* if you genuinely need the outer scope inside the Repeater body.
*   **Add a fallback Condition Block** at the end of a Modular Block Repeater to catch new block types; otherwise new types render as nothing.

## CMS Binding

*   **Bind first, customise later.** Drop a component, bind every prop that's content, then style. Builds in the data dependency from the start.
*   **Prefer simple paths.** template.title is cleaner than template.featured.metadata.computed\_title. Deep paths break when authors change CT structure.
*   **Document which fields a section expects.** Add a description on the section composition so other authors know what shape to bind it to.
*   **Pinned Data is per Freeform composition.** Don't try to share pinned entries across compositions; pin them per page.

## Design and Styling

*   **Register tokens before components.** Components reference tokens via CSS variables; tokens must exist first.
*   **Narrow styleSections per component.** Showing every CSS section for every component bloats the panel. A button doesn't need overflow controls.
*   **Set token-level / class-level / arbitrary early.** Switching mid-project means re-styling everything. Decide before authors start composing.
*   **Use bindings for varying styles per entry.** Don't fork sections to vary background colour per page; bind the colour to an entry field instead.
*   **Define breakpoints once via registerBreakpoints.** Don't rely on authors typing media-query CSS.

## Content Structure

*   **One Global Field, many content types.** Embed Global Fields wherever a shape repeats. Linked-schema matching prefers Global Fields.
*   **Use modular blocks for "different things in a list".** Use repeating groups for "same thing N times".
*   **Slug fields drive URL patterns.** Make sure every linked CT has a URL-shaped field (url, slug, etc.) and use it in the template's URL pattern.
*   **Plan localization upfront.** Add locales in Contentstack before authoring; switching mid-project requires reflowing content.

## Project Organization

*   **One Studio project per stack environment.** Keep stage / production cleanly separated.
*   **Share component libraries across projects via a published package.** See [Publishing the library](/docs/studio/publishing-the-component-library).
*   **Version your component library.** Treat the package version as the schema version; breaking changes (renamed type, removed prop) deserve a major bump.
*   **Document linked schemas at the section level.** Every reusable section's description should say what shape it expects.

## Security and Performance

*   **.env.local for credentials, never source files.** Stack API Key is public; Delivery Token and Preview Token are secret.
*   **Lazy-register heavy components.** Chart libraries, video players, rich-text editors; defer the chunk until needed.
*   **Use SSR or SSG for visitor pages.** Pure CSR is fine for the canvas route, weak for SEO on real pages.
*   **Wire onEntryChange to refetch.** Without it, Live Preview won't update the page when authors edit.
*   **searchQuery is required on the server.** Don't skip it; Studio iframe overrides won't apply.
*   **<StudioComponent /> for templates, <StudioCanvas /> for the canvas route.** They're not interchangeable.

## Figma Workflow

*   **Sync existing components to the Figma plugin first.** Designers see what's available before designing.
*   **Generate from Figma into your project.** Use the [Studio CLI](/docs/studio/studio-cli) or [Figma generate](/docs/studio/generate-components-from-figma) skill for reusable components.
*   **Use copy/paste only for one-off layouts.** It produces composition trees, not React components.
*   **Name Figma layers meaningfully.** Layer names carry into Studio's Layers tab and into generated component names.

## Layers Panel

*   **Name layers when the structure isn't obvious.** A Box named "Hero container" beats the fourth Box from the top.
*   **Keep nesting shallow.** Five levels of nested Boxes is a smell; refactor into a section.
*   **Use Layers to debug binding scope.** Click a layer to see its scope in the right panel.

## What NOT to Do

A short list of anti-patterns:

*   **Don't disable Live Preview** to "simplify" Studio. The canvas iframe relies on Live Preview's pipe; disabling it breaks the editor.
*   **Don't put <StudioCanvas /> on multiple routes.** One canvas route per project. Anything else fragments preview behaviour.
*   **Don't rely on defaultValue for required data.** Defaults are author guidance, not runtime guarantees. If a prop must have a value, validate at the component level.
*   **Don't use any props except for prototypes.** They bypass type checking and form controls; authors get a raw JSON editor.
*   **Don't bind every prop.** Some props are styling, layout, or design intent; keep those static. Bind content, not configuration.
*   **Don't fork sections for cosmetic differences.** Expose props, use slots, or vary the design via tokens, but keep the section count low.

## Summary Table

Topic

Bring your own components

Eager registerComponent default; lazy only for heavy bundles

Section design

Slots for content drops, exposed props for value overrides, linked schemas for data shape

Lists

Repeater for same-shape; Repeater + Condition Block for mixed

Bindings

Simple paths beat deep ones; template.\* is scope-aware

Styling

Tokens > classes > arbitrary, in that preference order

Project hygiene

One project per stack environment; component library as a versioned package

Performance

Lazy-load heavy components; SSR for visitor pages; wire onEntryChange

Two SDK components

<StudioCanvas /> for canvas route, <StudioComponent /> for templates
