[afifurrohman-id]

Description

When i using fresh from project template and i run deno task start will got error need --unstable flags, but i already include

In Deno json

{
"tasks"{
    "check": "deno lint --unstable . && deno check --unstable **/*.ts && deno check --unstable **/*.tsx"
  }
}

Error

error: TS2551 [ERROR]: Property 'openKv' does not exist on type 'typeof Deno'. Did you mean 'open'? 'Deno.openKv' is an unstable API. Did you forget to run with the '--unstable' flag, or did you mean 'open'? If not, try changing the 'lib' compiler option to include 'deno.unstable' or add a triple-slash directive to the top of your entrypoint (main file): /// <reference lib="deno.unstable" />
export const kvDb = await Deno.openKv()
                               ~~~~~~
    at file:///D:/path/to/ptoject/db.ts:4:32

    'open' is declared here.
      export function open(
                      ~~~~

But When i run command immediately no problem

deno lint --unstable . && deno check --unstable **/*.ts && deno check --unstable **/*.tsx

Follow this step on the error message:

or add a triple-slash directive to the top of your entrypoint (main file): /// <reference lib="deno.unstable" />

It's necessary in Fresh because it adds /// <reference no-default-lib="true" /> to the entrypoint, which will erase the unstable types, but adding /// <reference lib="deno.unstable" /> will add them back.
