Questions tagged [angular10]

Questions about Angular version 10, the web framework from Google. Use this tag for Angular questions which are specific to only version 10. Use tag Angular for any Angular questions which are not specific to an individual version

Breaking Changes:

  • Typescript 3.6, 3.7, and 3.8 are no longer supported. update to Typescript 3.9.
  • Input fields of type number fire the valueChanges event only once per value change (as opposed to twice in some cases). See PR 36087.
  • The minLength and maxLength validators only validate values that have a numeric length property. See PR 36157.
  • Templates with unknown property bindings or unknown element names now log errors instead of warnings. See PR 36399.
  • UrlMatcher can now return null values. See PR 36402.
  • Transplanted views now refresh at insertion point only. See PR 35968.
  • Formatting times with the b or B format codes now supports time periods that cross midnight. See PR 36611.
  • Navigation is canceled for routes with at least one empty resolver. See PR 24621.

See the changelog for latest version information.
