Describe a strategy for effectively managing and updating Bootstrap dependencies in a large-scale project.
- Use package managers like npm or yarn to manage dependencies, specify the Bootstrap version in the project's package.json, and regularly update dependencies while testing for compatibility.
- Manually download and include Bootstrap files in the project, avoiding package managers to have better control over versions, and update dependencies only when absolutely necessary.
- Rely on Content Delivery Networks (CDNs) for Bootstrap, as they handle updates automatically, reducing the need for manual management.
- Never update Bootstrap dependencies in a large-scale project to avoid potential disruptions.
In a large-scale project, using package managers like npm or yarn to manage Bootstrap dependencies allows for efficient version control and easy updates. Regular testing ensures compatibility and stability throughout the project.
