Standalone openapi yaml schema generation

[marceloverdijk]

Is it possible to generate a openapi yaml schema file from the command line? Eg running a npm command? Without the server running.

Rationale:
In development workflow I would like to generate the yaml as it will be used as input for another npm task to generate a openapi client.
During (prod) build I would like to run both to make sure everything is correct.

Second question is whether it is possible to disable the docs endpoint and yaml/json when server is running.

To answer my second question:

const router = OpenAPIRouter({
  docs_url: null,
  redoc_url: null,
  openapi_url: null,
});

For my first question this is interesting: https://cloudflare.github.io/itty-router-openapi/advanced-user-guide/ci-cd-pipelines/

import fs from 'fs'
import { router } from '../src/router'

// Get the Schema from itty-router-openapi
const schema = router.schema

// Optionaly: update the schema with some costumizations for publishing

// Write the final schema
fs.writeFileSync('./public-api.json', JSON.stringify(schema, null, 2))

I tried that like with generate-openapi.ts in my project root containing:

import fs from 'fs';
import { router } from './functions/api/_middleware';

// Get the Schema from itty-router-openapi
const schema = router.schema;

// Write the final schema
fs.writeFileSync('./public-api.json', JSON.stringify(schema, null, 2));

and running it using a script defined in my package.lock like:
"generate-openapi": "ts-node ./generate-openapi.ts",

but it gives:

node:13239) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

I tried to resolve it change package.json, introducing a special tsconfig for the script, but I had no luck unfortunately.
