I think there is a syntax error in your code, but more fundamentally node-couchdb seems to be an inactive library that has not been updated in more than four years. I would recommend using nano, which is the official Apache CouchDB NodeJS library.
Here's a simple NodeJS script (index.js) using nano to list your databases.
const nano = require('nano')(process.env.COUCH_URL)
const main = async function() {
const response = await nano.db.list()
console.log(response)
}
main ()
You will need to create an environment variable called COUCH_URL:
export COUCH_URL="http://user:password#localhost:5984"
and then run the script:
node index.js
