from replit.object_storage import Client
client = Client()

# Upload a text file that contains the text "Hello, World!"
client.upload_from_text("file.txt", "Hello World!")

# List the objects in the bucket
objects = client.list()
print("Bucket contents:", objects)

# Retrieve and print the contents of the uploaded file
contents = client.download_as_text("file.txt")
print("file.txt contents: ", contents)
3

Run the app

Select Run to execute the example code.Navigate to the Console tab to view the output, which should resemble the output below:
Bucket contents: [Object(name='file.txt')]

Reload the page to update the object list if file.txt fails to appear.

​
Delete the object

To remove the file.txt file from the bucket,
  1. Replace the content of main.py with the following code: 
    from replit.object_storage import Client
client = Client()

# Delete file.txt from the bucket
client.delete("file.txt")
print("Delete succeeded")
  2. Select Run to execute the example code.
