Invoke a JavaScript file within the MongoDB shell

Running a JS file directly from the Mongo shell using the query

mongo localhost:27017/west createSumCollection.js

has resulted in an error:

"uncaught exception: SyntaxError: unexpected token: identifier : @(shell):1:6"

The content of CreateSumCollection.js includes basic database usage and db.createCollection with a simple object id and another field.

What could be causing this issue? The same script runs perfectly when executed directly in the mongoshell.

Attempting to load("C:/mongodb/data/db/createSumCollection.js") failed due to the "use west" statement. Removing this statement allowed the load to work. I am curious about the difference between load and mongo localhost:27017/west createSumCollection.js and how to successfully run the JS file directly.

Answer №1

use is a handy command that can only be used in the interactive shell environment.

When working in the interactive shell (or using load), you can enter the following commands:

use my_database
db.collection.find()

To achieve the same result in a JavaScript file on the command line, you would need to use:

db.getSiblingDB("my_database").collection.find()
