NOTE: this rule is part of the jsr rule set.

Enable full set in deno.json:

{
  "lint": {
    "tags": ["jsr"]
  }
}

Enable full set using the Deno CLI:

deno lint --tags=jsr

Enforces type imports to be declared as type imports.

This rule ensures that the code works when the verbatimModuleSyntax TypeScript compiler option is enabled. This is useful in libraries distributing TypeScript code in order to work in more scenarios.

import { Person } from "./person.ts";

const person: Person = {
  name: "David",

const person: Person = {
  name: "David",
};
output(person);

const person: Person = {
