Example

Think of Supabase as your project’s database, like a collection of spreadsheets:
  1. Choose where to read from:
    • Project: “My App” (like picking which spreadsheet file)
    • Table: “Users” (like selecting which sheet to read)
  2. Control how much to read:
    • Number of Records: 10 (will read first 10 rows)
The node will then output data from each column in your table, like getting specific columns from a spreadsheet.

​
Important Considerations:

  1. Requires Authentication with Supabase - Set up in the Credentials page
  2. Tables must exist in your project
  3. Output format matches table structure
  4. Default limit is 10 records
In summary, the Supabase Table Reader node provides straightforward access to your Supabase database tables, making it easy to retrieve and use stored data in your workflows.
