What is Metadata?
When developing on the Steedos platform, understanding the role of metadata is crucial. Steedos operates with metadata at its core, facilitating the model of "low-code" and ensuring system adaptability and scalability. This guide will introduce Steedos DX metadata, its importance, and how developers can effectively engage with it.
Understanding Metadata in Steedos
What is Metadata?
Metadata in the Steedos environment refers to the data that describes the structure, data model, business logic, and even the UI of your applications. It encompasses a wide range of configurations, such as object definitions, fields, roles, workflows, and page layouts, amongst others.
Why is Metadata Important?
- Consistency and Maintainability: By defining the structures and elements, metadata provides a consistent framework that aids in application development. It makes the system easily maintainable.
- Upgradability: Since the configuration is separated from the core platform, updates and migrations become less cumbersome.
- Collaboration: Metadata can be version-controlled, making it easier for teams to collaborate, track changes, and maintain a history of configurations.
- Rapid Deployment: Changes in metadata are reflected almost immediately, enabling quick iterations for development teams.
Working with Metadata in Steedos DX
Steedos DX uses a folder-based structure to store metadata, commonly found in the project's root directory. The typical components include:
- Objects: Contains the definitions for custom objects and fields. Each object would have its own sub-directory.
- Layouts: Comprises the configuration for UI layouts.
- Workflows & Triggers: Contains the business logic and automation processes.
- Permissions: Defines roles and sharing rules.
Best Practices for Handling Metadata
- Version Control: Always use version control systems like Git to track changes in metadata. It's essential for collaboration and rollback.
- Use Descriptive Naming: Name your metadata components in a way that reflects their purpose and context within the application.
- Organize Metadata: Maintain a logical folder structure and organize the metadata to reflect the system's architecture.
- Document Changes: Keep comprehensive documentation for custom metadata, including the reason for changes, to understand the evolution of the system components.
With Steedos DX, you can deploy metadata directly through the command line interface (CLI). It simplifies the process of moving configurations between environments (e.g., from development to production).
