Netsuite Uif Spa Reference

NetSuite UIF Reference

Complete type definitions for @uif-js/core and @uif-js/component, the two packages that power NetSuite SPA (single-page application) user interfaces.

When to Use

• Building or modifying a UIF SPA component (JSX files)
• Looking up the exact API for a UIF class (Date, ArrayDataSource, Router, etc.)
• Checking available props/methods on UIF components (DataGrid, StackPanel, Button, etc.)
• Debugging runtime errors from UIF framework code
• Verifying enum values (for example, Button.Hierarchy, GapSize, DataGrid.ColumnType)
• Understanding UIF Date vs. Native Date behavior

Reference Data

The type definitions are located in the references/ subdirectory.

Lookup Instructions

To find information about a specific class or component:

1. Search by class name:

   Search for `class Date` in the local `references/` directory.
   

2. Search by method name:

   Search for `lastOfMonth`, `firstOfMonth`, or `addDay` in `references/core.d.ts`.
   

3. Search by enum:

   Search for `enum GapSize`, `enum Hierarchy`, or `enum Type` in `references/component.d.ts`.
   

4. Read a section: Once you find the line number, open that part of the file to view the full definition.

Key Classes Quick Reference

@uif-js/core

@uif-js/component

Global Component Enums

These enums are available directly from @uif-js/component and are used across many components.

GapSize

Used for itemGap, outerGap, contentGap on StackPanel, GridPanel, ContentPanel, AccordionPanel, etc.

NONE, XXXXS, XXXS, XXS, XS, S, M, L, XL, XXL, XXXL, XXXXL SPACING1X through SPACING12X, SMALL, MEDIUM, LARGE.

import { GapSize } from '@uif-js/component';
<StackPanel itemGap={GapSize.M} outerGap={GapSize.L} ... />

Note: Some components (StackPanel, GridPanel) expose their own nested GapSize type. The top-level GapSize export from @uif-js/component is the standard enum to use.

InputSize

Used for size on TextBox, Dropdown, DatePicker, TimePicker, Switch, etc.

AUTO, XXS, XS, S, M, L, XL, XXL

VisualizationColor

Semantic color set for Kpi, Reminder, Banner, Avatar, Badge color props:

NEUTRAL, SUCCESS, WARNING, DANGER, INFO, TEAL, ORANGE, TURQUOISE, TAUPE, GREEN, PINK, BROWN, LILAC, YELLOW, PURPLE, BLUE, PINE

Known Pitfalls from Production Experience

UIF Date

• Date.now() returns a UIF Date object, not a number like native Date.now().
• UIF Date uses .year, .month, .day properties (not .getFullYear(), .getMonth(), .getDate()).
• .month is 0-indexed (January = 0).
• UIF SPA runtime does not replace global Date; new Date() creates a native JS Date.
• Only import { Date } from '@uif-js/core' returns UIF Date.
• If the import fails silently, Date falls back to native Date and Date.now() returns milliseconds.

StackPanel

• StackPanel rejects all null children; {cond ? <Item>... : null} will throw an error.
• Empty arrays are also rejected; {emptyArray} inside StackPanel causes "Invalid StackPanel item" error. Never spread or inline an array that may be empty. Use a for-loop to append items: for (var i = 0; i < items.length; i++) rootItems.push(items[i]);.
• Only safe pattern: Imperative array building: var items = []; if (x) items.push(<Item>...</Item>);.
• StackPanel.Item must have exactly one child.

Modal Placement

• Modals must be at the root component level. Placing modals inside deeply nested containers (for example, GridPanel > ContentPanel > StackPanel) causes stacking context issues where the modal renders inline behind page content instead of as a floating overlay.
• Push modal <StackPanel.Item> elements into the root-level items array, not into a nested content array.
• Always use imperative array pattern for modals: build a modalItems array, then append to root items via for-loop.

Badge

• Badge.Size exists with values DEFAULT and SMALL; use size={Badge.Size.SMALL} for compact badges.
• classList prop uses DOMTokenList.add() internally; space-separated strings throw InvalidCharacterError.
• Always use a single class name per classList value.

DataGrid

• Full-width grids: columnStretch={true} distributes column space proportionally, but only within the grid's own computed width; it does not make the grid fill its container. To achieve full-width:
  1. Always keep explicit width on every column; these act as proportional weights for columnStretch. Without them, columns collapse to tiny minimums.
  2. Add rootStyle={{ width: '100%' }} on the DataGrid to make it fill its parent container's width.
  3. Give wider columns a larger width value (for example, Description: 500, Name: 250, Badge: 70) so they get more proportional share.
• rootStyle is inherited from the base Component class; all UIF components accept rootStyle={{ ... }} for inline CSS on the root DOM element.
• Do not use stretchStrategy={{}}; it is constructor-only and causes VDom "Writable property not found" errors on re-render.
• TEMPLATED column content callback: args has {cell, context}, use args.cell.value or args.cell.row.dataItem.
• Always wrap TEMPLATED callbacks in try/catch; unhandled throws blank all remaining columns.
• dataRowHeight is the correct prop for row height; rowHeight is silently ignored.
• CHECK_BOX columns require grid-level editable={true}; setting editable: true on the column definition alone is not sufficient. Without editable={true} on the DataGrid itself, the column space renders but the checkbox widget is invisible.
• CHECK_BOX columns + CELL_UPDATE is unreliable; DataGrid.Event.CELL_UPDATE may not fire when checkboxes are toggled, making it impossible to track selection state. Preferred pattern: Use a TEMPLATED column with a toggle Button (for example, label={checked ? '\u2611' : '\u2610'}). Manage checked state in a useRef({}) keyed by row ID. The Button action flips the ref entry and calls a setState counter to trigger re-render.
• DataGrid.Options – key constructor-only vs writable props: The Options interface (constructor) accepts many properties that are NOT writable after construction:
  • Constructor-only: stretchStrategy, autoSize, bindingController, editingMode, preload, defaultColumnOptions, lockedLevels, beforeEditCell, stripedRows, multiColumnSort, allowUnsort
  • Writable: columnStretch, editable, paging, pageSize, pageNumber, sortable, placeholder, showHeader, highlightRowsOnHover
• maxViewportWidth – Similar to maxViewportHeight, limits horizontal viewport. Use for grids with many columns to prevent horizontal overflow.
• stripedRows={true} – Enables alternating row stripes for readability. Constructor option.
• editingMode – DataGrid.EditingMode.CELL (default) or DataGrid.EditingMode.ROW. ROW mode edits all cells in a row simultaneously.
• multiColumnSort={true} – Enables sorting by multiple columns. Off by default.
• allowUnsort={true} – Lets users click a sorted column back to unsorted state.
• Selection system – DataGrid has built-in selection via SelectionColumn type and DataGrid.SingleSelection/DataGrid.MultiSelection strategies. More reliable than CHECK_BOX columns for row selection.
• Useful imperative methods – autoSize(), stretchColumns(), reload(), rowForDataItem(dataItem), scrollTo({cell/row/column}), pinRow(row, section).

Select / Dropdown

• Select does not exist in @uif-js/component; importing it resolves to undefined. Using <Select> in a TEMPLATED column silently throws, and try/catch fallbacks mask the error (renders em-dash or blank instead of a dropdown).
• For dropdown components inside DataGrid: Use DataGrid.ColumnType.DROPDOWN with these key options:
  • inputMode: DataGrid.InputMode.EDIT_ONLY; makes the dropdown always visible (not just on click).
  • valueMember: 'value', displayMember: 'label', bindToValue: true; binds to the value property, displays the label.
  • dataSource: static ArrayDataSource (cache via useRef to avoid recreation each render).
  • dataSourceConfigurator: function(row) { return new ArrayDataSource([...]); }; for per-row dynamic options.
  • widgetOptions: { allowEmpty: true, placeholder: 'Unassigned' }; passed through to the underlying Dropdown widget.
  • Wire value changes via DataGrid.Event.CELL_UPDATE on the grid's on prop, not via onChange on individual cells.
  • The grid itself must have editable={true} for DROPDOWN columns to be interactive.
• For standalone dropdowns outside DataGrid: Use Dropdown from @uif-js/component (not Select).

Modal

• Modal.Size enum only has: DEFAULT, SMALL, MEDIUM, LARGE; there is no EXTRA_LARGE.
• Modal.Size.LARGE has an internal max-width that rootStyle cannot override when both are set. The size prop's CSS takes precedence.
• For wider-than-LARGE modals: Remove the size prop entirely and control width via rootStyle only:

  <Modal rootStyle={{ width: '80vw', maxWidth: '1200px' }} ... />
  

• When a DataGrid is inside a Modal, always add rootStyle={{ width: '100%' }} on the DataGrid so it fills the modal's content area.
• onClose is not a valid prop; using onClose={handler} throws "VDom: Writable property onClose not found" and prevents the modal from rendering. Modal/Window has no onClose callback prop. To handle close, use closeButton={false} and provide your own Close <Button> inside the modal content. For event-based close handling, use on={{ [Window.Event.CLOSED]: handler }}.

MenuButton

• MenuButton extends Button; accepts all Button props (label, icon, type, hierarchy, etc.) plus menu (array of MenuItem.ItemDefinition or Menu.Options).
• Menu items are ActionItemDefinition objects: { label: 'Text', action: function() { ... } }. The action property is what makes UIF treat them as clickable action items (vs submenu items which only have label/icon).
• Do not set icon: null on menu items; this can interfere with UIF's internal type discrimination between ActionItemDefinition and SubmenuItemDefinition, causing clicks to silently do nothing.
• Use SystemIcon.OVERFLOW for the standard three-dot menu icon: <MenuButton icon={SystemIcon.OVERFLOW} type={Button.Type.GHOST} menu={items} />.
• Suppress tooltip with tooltip={null}; MenuButton inherits Button's tooltip behavior which can persist after the dropdown opens.
• In TEMPLATED DataGrid columns use ref-based handlers in menu item actions to avoid stale closures: { action: function() { myRef.current(item); } }.

General

• rootStyle is available on all UIF components (inherited from base Component class). Accepts Record<string, string> for inline CSS on the root DOM element. Useful for width, height, minWidth, maxWidth, etc.
• Never use empty <Text /> as conditional fallback; use null (but not inside StackPanel!).
• Large datasets: Cap ArrayDataSource at ~500 rows for preview grids.

Store / State Management

• Store.Provider must wrap the component tree above any component calling useDispatch() or useSelector(); missing it throws an error from both hooks.
• Reducer.create() takes an object mapping action type strings to handler functions. Each handler receives (state, action) and must return a new state object (never mutate).
• Use ImmutableObject.set(state, 'key', value) inside reducers to return updated state without mutation.
• Store.create() is constructor-only; create once at module level, not inside a component.
• Access the existing store in deep child components via useContext(ContextType.STORE) instead of prop-drilling.

useEffect / Async Cleanup

• Never update state after component unmount; always create a CancellationTokenSource at the top of useEffect, declare var token = source.token, pass token to async operations, call source.cancel() in the cleanup function, and check token.cancelled before calling any state setter.
• Correct pattern:

  useEffect(function() {
      var source = new CancellationTokenSource();
      var token = source.token;
      Ajax.get({ url: '/api/data' }).then(function(result) {
          if (token.cancelled) return;
          setData(result.data);
      });
      return function() { source.cancel(); };
  }, []);
  

DataGrid – TreeDataSource

• TreeDataSource for hierarchy: Use new TreeDataSource({ data: items, childAccessor: (item) => item.children }) as the dataSource prop. The first column must be DataGrid.ColumnType.TREE (not TEXT_BOX) to render the expand/collapse control. ArrayDataSource with manual indent does not support expand/collapse.

Form Building

• Always wrap form controls in Field for consistent label spacing, accessibility, and mandatory indicators; bare TextBox + adjacent Text label is not the correct pattern.
• Field.Mode.VIEW renders the control as read-only display text; use for detail/view screens without creating separate read-only components.
• FieldGroup collapses a logical group of fields with a section title; preferred over bare StackPanel dividers for long forms.
• RadioButtonGroup (not individual RadioButton for groups) manages selection state automatically.
• Field.Size full enum: AUTO, SMALL, MEDIUM, LARGE, XLARGE, XXLARGE, STRETCH.

User Feedback (Banner / Growl)

• GrowlPanel must be in the component tree; it is not a service call. Add it once in the root shell, obtain a ref to it, then call .add(msg) (not .addMessage()) to push a GrowlMessage.
• Do not use Modal for success/error feedback; use GrowlMessage for transient feedback and Banner for persistent inline alerts.
• Banner is always visible until dismissed; GrowlMessage auto-dismisses on a timer unless manual={true} is set on the parent GrowlPanel.
• Banner.Color values: BLUE (informational), BLUE_DARK (emphasis), GREEN (success), ORANGE (warning).

FilterPanel

• FilterPanel.filters and FilterPanel.filtersVisibilityToggle are deprecated; use activeFilters + showClearAll instead.
• FilterChip requires a picker prop (for example, FilterChip.textBox, FilterChip.date static pickers) to open the selection UI; without it the chip is display-only.

Immutable State Updates

• Never mutate state directly; state.items.push(x) does not trigger re-render; use ImmutableArray.push(state.items, x) and pass the result to the state setter.
• ImmutableObject.set(state, 'loading', true) is the correct pattern inside Store reducers; always return a new object, never Object.assign(state, ...).
