v4.0.0

Polaris React v4.0.0 is a major release that introduces breaking changes, primarily due to updates made to component internals. This builds a stronger foundation that ensures readiness for future React performance improvements.

This release doesn’t include any new components, but it does update some components to use React Hooks. It also deletes several deprecated features and removes dependencies on legacy context and unsafe lifecycle methods. Thanks to these improvements, Polaris React is React Strict Mode compliant.

For instructions on updating from v3 to v4, read the migration guide.

Breaking changes

  • Removed groups prop on Select. Pass groups to the options prop instead. (#1831)
  • Removed Autocomplete.ComboBox.TextField and Autocomplete.ComboBox.OptionList. You should use the Autocomplete.TextField and OptionList components instead. (#1830)
  • Removed secondaryFooterAction prop on Card. Pass an array of secondary actions to the secondaryFooterActions prop instead. (#1831)
  • Removed iconBody prop on Navigation.Item. Pass a string to the icon prop instead. (#1831)
  • Removed the WithContext component, as it was an undocumented part of the public API meant for internal use only (#1641)
  • Removed the WithRef component, as it was an undocumented part of the public API meant for internal use only (#1610)
  • Removed support for passing a string into <Icon source> to load a bundled icon. You must load the required icon directly from @shopify/polaris-icons instead. (#1604)
  • Removed support for passing an SvgSource shaped object into <Icon source> to load an icon imported using Shopify’s legacy icon loader. You must update sewing-kit to at least v0.82.0 which replaced the legacy loader with using SVGR. (#1604)
  • Removed support for passing a React Element into <Icon source>. You must pass in a React Component that returns an SVG element instead. (#1604)
  • Removed support for <Icon untrusted>. Passing a string into source will now always load an untrusted icon, you don't need that additional property. (#1604).
  • Removed Navigation.UserMenu. Use TopBar.UserMenu instead. (#1599)
  • Made title a required prop on ChoiceList to improve accessibility. It can be hidden with titleHidden. (#1575)
  • Made i18n a required prop on AppProvider. Usage instructions are included in the AppProvider docs. (#1530)
  • Upgraded react and react-dom peer-dependencies to 16.8.6 to enable the use of hooks (#1525)
  • Changed the import method for React to use default imports. Applications consuming Polaris using TypeScript must enable esModuleInterop in tsconfig.json. (#1523)
  • Removed LinkLikeComponent type export. Use AppProviderProps['linkComponent'] instead. (#1864)
  • Removed the Modal.Dialog and Tabs.Panel subcomponents as they were undocumented parts of our public API meant for internal use only (#1899).
