Issue
I would like there to be global Javascript objects and queries that I can use for central utility functions and look-up tables on multiple pages. Currently, I have to copy them repeatedly and changes are complex, as I have to replicate them on all pages. This is a horror for me as a developer.
Resolution
Appsmith offers a powerful feature called Packages, available on the Business plan, that allows you to define reusable logic—such as JavaScript functions, constants, and queries—and use them across multiple pages (and even across apps).
What Are Packages?
Packages let you create centralized JavaScript modules for:
- Utility functions (
validateEmail,formatDate, etc.) - Global constants and config
- Shared look-up tables
- Reusable business logic
This removes the need to copy/paste code across pages and makes updates significantly easier to manage.
Why Use Packages?
- Single Source of Truth: Define once, use everywhere.
- No Duplication: Eliminate manual copying between pages.
- Cleaner App Structure: Promote modular design and maintainability.
- Cross-App Reusability: Share logic across different apps with import/export support.
If you're managing growing projects or building for multiple environments, Packages make it dramatically easier to scale with clean, reusable logic—without the copy-paste chaos.
