Import assertions are not supported

Rule arkts-no-import-assertions

Severity: error

ArkTS does not support import assertions because in the language import is a compile-time, not a runtime feature. So asserting correctness of imported APIs in runtime does not make sense for the statically typed language. Use ordinary import syntax instead.

TypeScript

    import { obj } from "something.json" assert { type: "json" }

ArkTS

    // Correctness of importing T will be checked in compile-time:
    import { something } from "module"
