Certainly! Here's a revised README.md
for the start
bundle in BeyondJS, focusing on its optional nature, the concept
of a transversal bundle, and providing guidance on how to configure a module with the start
bundle.
BeyondJS start
Bundle
Overview
In BeyondJS, the start
bundle is a specialized transversal bundle designed to execute code at the very beginning of an
application's lifecycle. It is not mandatory for every BeyondJS application but is instrumental when initial execution
logic is needed before any other part of the application loads.
What is a Transversal Bundle?
A transversal bundle in BeyondJS refers to a type of bundle that cuts across the typical modular boundaries of an application, potentially affecting or interacting with multiple modules. Transversal bundles are used to implement cross-cutting concerns that are relevant across different parts of an application, such as logging, configuration settings, or initialization code.
Usage Guidelines
Configuring a Module with a start
Bundle
To use a start
bundle in your BeyondJS application, you must configure it within a module's module.json
. Here’s how
to set up a module to utilize the start
bundle:
- Create a
module.json
File: Define amodule.json
in your module directory. - Specify the Bundle Type: Set the bundle type to
start
to indicate that this module will be loaded first upon application startup.
Example module.json
Configuration
Here is an example configuration for a module utilizing a start
bundle:
{
"name": "initial-setup",
"bundle": "start",
"ts": {
"files": "*"
}
}
This configuration tells BeyondJS that the initial-setup
module should use the start
bundle, ensuring that any
scripts within are among the first executed.
When to Use the start
Bundle
- Initial Application Setup: Use the
start
bundle for code that needs to run before the main application logic begins, such as setting up configurations, pre-loading necessary data, or setting initial state. - Cross-Cutting Concerns: Ideal for implementing functionality that impacts multiple areas of the application, ensuring that all modules start with a consistent setup.
Advantages of Using the start
Bundle
- Controlled Initialization: Provides precise control over the order in which code executes when the application starts.
- Enhanced Modularity: Helps keep the application modular by isolating initialization logic in a specific bundle, making it easier to manage and update.
- Flexibility: Offers flexibility in managing dependencies and initial execution without altering the core logic of other modules.
Best Practices
- Keep It Light: Only include essential initialization code in the
start
bundle to avoid delaying the application startup. - Clear Documentation: Clearly document what the
start
bundle does within your project documentation to ensure that all team members understand its role. - Error Handling: Implement robust error handling within the
start
bundle to prevent startup errors from crashing the application.
Conclusion
The start
bundle is a powerful tool in BeyondJS for managing early application behavior and ensuring a smooth initial
setup. By effectively using this transversal bundle, developers can enhance their application’s modularity and startup
performance.
This README.md
better aligns with the role of the start
bundle as an optional, transversal component within a
BeyondJS application, providing clear guidelines on how and when to use it effectively.
