Single Spa vs Web Components

Developers should use Single Spa when building large-scale web applications where multiple teams need to work on separate frontend modules without tight coupling meets developers should learn web components when building reusable ui elements that need to work independently of any javascript framework, ensuring long-term maintainability and interoperability in large-scale applications. Here's our take.

Single Spa

Nice Pick

Developers should use Single Spa when building large-scale web applications where multiple teams need to work on separate frontend modules without tight coupling

Pros

• It is ideal for scenarios requiring incremental upgrades, such as migrating from a legacy monolith to modern frameworks like React or Vue, or for enterprise applications with complex, modular architectures
• Related to: javascript, react

Cons

• Specific tradeoffs depend on your use case

Web Components

Developers should learn Web Components when building reusable UI elements that need to work independently of any JavaScript framework, ensuring long-term maintainability and interoperability in large-scale applications

Pros

• They are particularly useful for design systems, micro-frontends, and embedding third-party widgets, as they provide native browser support without external dependencies
• Related to: javascript, html5

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Single Spa is a framework while Web Components is a concept. We picked Single Spa based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Single Spa wins

Based on overall popularity. Single Spa is more widely used, but Web Components excels in its own space.
