Package.json: understanding our dependencies

peerDependencies

react : Core runtime required by all Echoes React components.
react-dom : Required for DOM rendering and portals used by some components.
react-intl : Required for components relying on internationalization.
react-router-dom : Required by components integrating with routing/navigation context.
@emotion/react : Required styling runtime for Emotion-based components.
@emotion/styled : Required for Emotion styled-component APIs used in the library.

@mantine/core : Used as a base for some components (Select, MultiSelect). We maintain a patch to add withExpandedAttribute on Combobox.Target in Select so the trigger exposes the expected aria-expanded state for accessibility and tests.
@mantine/hooks : Used with @mantine/core as a base for some components (Select, MultiSelect).
Sonner : Used as the base component for Toast notifications
@radix-ui/react-radio-group (patch): Replaces an internal callback-ref + useState pattern with useRef to avoid ref-driven render loops (notably with React 19) that can cause maximum update depth errors.

@testing-library/react : Used for component and interaction testing. It should stay aligned with our React major version.
@emotion/cache : Used by Emotion/Mantine styling internals.
@emotion/serialize : Used by Emotion style serialization internals.
@emotion/utils : Used by Emotion runtime/style utilities.

@radix-ui/react-compose-refs (patch): Prevents forwarding null to function refs. This avoids repeated ref teardown/setup feedback loops that can retrigger state updates.
ast-types: Transitive dependency of Storybook. It is apparently incompatible with typescript 5.4+, but we've never been impacted (why?). With the bump to storybook 9, it requires a patch not to fail ts-check. See this issue
axios: Transitive dependency of sonarqube-scanner. The version required by sonarqube-scanner (1.13.2) is vulnerable, but the latest version of axios is compatible with sonarqube-scanner, so we can safely override it.
