using both nodejs & deno

I have to turn in my class assignments in nodejs. I am happier with deno. Is there a standard way to write code so that the same code base can be used both ways? My naive though would to hide the differences behind maps. Is there a better way to accomplish this?

get in oak

In oak, how do I check whether a request is the root? It - starts with slash - is of length 1 but is NOT equal to "/"

app.use(async (ctx, next) => {
  console.log({pathname: ctx.request.url.pathname})
  const starts_with_slash = ctx.request.url.pathname.startsWith("/")
  const is_not_slash = (!ctx.request.url.pathname != "/")
  const the_length = ctx.request.url.pathname.length 

  console.log({starts_with_slash})
  console.log({is_not_slash})
  console.log({the_length})
  ...})

app.use(async (ctx, next) => {
  console.log({pathname: ctx.request.url.pathname})
  const starts_with_slash = ctx.request.url.pathname.startsWith("/")
  const is_not_slash = (!ctx.request.url.pathname != "/")
  const the_length = ctx.request.url.pathname.length 

  console.log({starts_with_slash})
  console.log({is_not_slash})
  console.log({the_length})
  ...})

console output

{ pathname: "/" }
{ starts_with_slash: true }
{ is_not_slash: true }
{ the_length: 1 }

{ pathname: "/" }
{ starts_with_slash: true }
{ is_not_slash: true }
{ the_length: 1 }

OR interfaces?

What should EITHER mean?

interface ONE {
  one: number;
  i: string;
}
interface TWO {
  two: number;
  j: string;
}

type EITHER = ONE | TWO;

interface ONE {
  one: number;
  i: string;
}
interface TWO {
  two: number;
  j: string;
}

type EITHER = ONE | TWO;

EITHER seems to accept anything that has * ALL the elements of either ONE or TWO, along with * zero or more elements of the other.

mongodb calls on DB's rather than collections

When I do a find on a mongoclient rather than a collection

  clnt: MongoClient,

  ...

  const fullCollectionCursorPair = await clnt.runCommand(dbname, {
    find: collectionName,
    filter: {},
  });

  clnt: MongoClient,

  ...

  const fullCollectionCursorPair = await clnt.runCommand(dbname, {
    find: collectionName,
    filter: {},
  });

I get a cursor with the proper looking data but without .hasNext() , .next() .map() or .toArray() defined on it as I would if I was using collection.find Is there a way for me to attach them? It looks like this normally defined in class CommandCursor<T> in denodrivers/mongo/src/protocol/
