in a dynamic provider i've got a lot of

public readonly serverUri: pulumi.Output<string>;

which is filled out by pulumi after apply but with

strict: true

in tsconfig.json it complains that it's "not definitely assigned in constructor" - is there any easy way around that please

There are a couple ways to address this. One way is to add definite assignment assertions to each property. https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-7.html#definite-assignment-assertions Adding an exclamation point after the property names like:

public readonly serverUri!: pulumi.Output<string>;

oh great thanks, didnt know about the ! thing
