Vue.js: What is the difference between Pinia and Vuex?

Pinia — simpler, modern. Vuex — traditional, complex.

Pinia:

• No mutations.
• Flat store structure.
• Better TypeScript.
• Smaller bundle.

Vuex:

• Mutations required.
• Nested modules.
• More boilerplate.
• Older API.

1// Pinia
2const store = useCounterStore()
3store.count++  // Direct mutation
4
5// Vuex
6state.commit("increment")  // Mutation
7state.dispatch("asyncIncrement")  // Action

Migration:

• Pinia is the official successor.
• Vuex 5 will be Pinia.
