Anthony Fu | Anthony's Road to Open Source - The Progressive Path | ViteConf 2024

The cost of tools should be less than the benefit they provide - involves cost of discovering, learning, adoption and the tool itself

Progressive adoption is key for tools and frameworks:

• Allow starting with minimal knowledge
• Enable gradual feature adoption
• Support coexistence with other technologies
• Provide smooth migration paths

Nuxt 4 approach to breaking changes:

• No new features in initial release
• Focus on revising previous decisions
• Allow opt-in to new behaviors
• Maintain backward compatibility
• Enable progressive migration

Vue’s progressive framework philosophy:

• Can start with single CDN import
• Scales from simple to complex use cases
• Works with existing codebases
• Integrates with other frameworks
• Provides multiple ways to use the framework

Strategies for managing breaking changes:

• Use feature flags for new functionality
• Provide middle stages for migration
• Keep changes opt-in when possible
• Ship smaller, more frequent updates
• Maintain ecosystem compatibility

Tools should grow with users by:

• Starting with minimal requirements
• Adding features progressively
• Supporting different expertise levels
• Maintaining good documentation
• Keeping the learning curve manageable
