I have few SPFx related queries as mentioned below.

  • What is the current version of typescript in SPFx v1.71?
  • if it is not the latest version then is there any plan to upgrade? It will be great to know the timeline if there is any.
  • If we have some external libraries with a dependency on latest version of typescript then is it possible to incorporate this new version in SPFx. If yes how?

Thanks, Rajashekar

SPFx 1.7.1 relies on typescript 2.4.2.
You can check that by creating a SPFx project and then run npm list typescript, look for the typescript entries bellow @microsoft/sp-build-common.

  • Thanks for the info.. I am still looking for the answers to remaining two questions too. Feb 18, 2019 at 1:51
  • The tooling of SPFx is locked down to this specific version of typescript and you should not upgrade typescript. For your external library, you should try to look for a version which is compatible with this version of typescript
