Configure typescript to output imports with extensions, ex: `from './file.js``

Using node 14.x I would like to switch my project to full ES Modules, as it's now supported.
So I enabled on package.json "type": "module"

and my tsconfig.json looks like that:

{
  "compilerOptions": {
    "outDir": "dist",                         /* Redirect output structure to the directory. */
    "strict": true,                           /* Enable all strict type-checking options. */
    "esModuleInterop": true,                  /* Enables emit interoperability between CommonJS and ES Modules via creation of namespace objects for all imports. Implies 'allowSyntheticDefaultImports'. */
    "skipLibCheck": true,                     /* Skip type checking of declaration files. */
    "forceConsistentCasingInFileNames": true, /* Disallow inconsistently-cased references to the same file. */
    "allowSyntheticDefaultImports": true,
    "lib": ["ES2020"],
    "module": "ESNext",
    "moduleResolution": "node",
    "target": "ES2020"
  }
}

But the output files have unspecified extension in imports, it's instead REQUIRED for node 14.x to specify full file ext

For example:

import { ENV, redisConfig } from './config';

should instead be:

import { ENV, redisConfig } from './config.js';
