Angular SSR (working with version 18)

 

Perfect! Let’s map out Angular Material & CDK services/components and classify them for SSR safety. This will clarify why your current mocks are necessary.

SSR Safety Map for Angular Material / CDK

Service / Component	Server-Safe?	Notes / SSR Issue	Recommendation
MatDialog	❌ Not safe	Calls Overlay.create(), which touches document.	Mock with MockMatDialog
MatSnackBar	❌ Not safe	Similar to Dialog, uses Overlay internally.	Mock with MockMatSnackBar
Overlay (CDK)	❌ Not safe	Core DOM service for popups/portals. Always crashes on SSR.	Must mock (MockOverlay)
MatBottomSheet	❌ Not safe	Uses Overlay under the hood.	Mock (MockMatBottomSheet)
MatTooltip	⚠️ Usually safe	Mostly attaches to host element lazily, but Overlay internally may be used.	Optional mock for default options, safe to just provide MAT_TOOLTIP_DEFAULT_OPTIONS
MatMenu	⚠️ Usually safe	Uses Overlay internally. Will crash if opened on server.	Guard .open() calls or mock Overlay
MatSelect	⚠️ Usually safe	Overlay for dropdown panel, crash if server tries to render panel.	Mock Overlay or lazy browser-only usage
MatAutocomplete	⚠️ Usually safe	Overlay for dropdown panel.	Same as MatSelect
MatTable	✅ Safe	Purely DOM table rendering.	No mock needed
MatPaginator / MatSort	✅ Safe	Only logic, no Overlay/DOM issues	No mock needed
MatFormField / MatInput	✅ Safe	Basic input rendering	No mock needed
MatCheckbox / MatRadio / MatSlideToggle	✅ Safe	No Overlay, purely DOM	No mock needed
MatStepper	✅ Safe	Pure DOM	No mock needed
CDK DragDrop	⚠️ Conditional	Needs document for coordinates if used	Guard with isPlatformBrowser

Summary

• Must Mock: Dialog, SnackBar, Overlay, BottomSheet

• Optional / Conditional: Tooltip, Menu, Select, Autocomplete, DragDrop (only if used on server)

• Safe: Form controls, tables, steppers, checkboxes, radios, inputs

Why Angular doesn’t provide this out-of-the-box

Angular Material assumes browser usage. Server rendering is secondary, so Angular provides no default SSR-safe mocks for Overlay or related services. You must provide them yourself—or guard usage.

If you want, I can enhance your SSR mocks even further so they cover tooltips, menus, selects, and autocomplete safely, without breaking SSR.

Do you want me to do that?

Caused by: given pom.xml dependencies conflict of packages or classes file.

mine was easy, just remove dependencies duplicated with packages or classes in JDK.

if u x hv access, directly will show 404 instead of no access

Maven Build Skip Test

Source URL: https://stackoverflow.com/a/21933970

"maven.test.skip.exec=true" the tests get compiled, but not executed.

"maven.test.skip=true" doesn't compile or execute the tests.

"-DskipTests" is the same as "maven.test.skip.exec=true"
