Problem

In order to migrate the Query Builder's code base away from Vue 2 to Vue 3 and avoid the consequences of Vue 2's EOL, we will have to migrate various peer dependencies such as Vuex (@4.0).

Solution

As part of the preparation work to migrate the Query Builder's front-end from Vue to Vue Compat layer, we'll replace Vuex by Pinia. The latter store library brings certain advantages, such as a simpler API or better Typescript support.

Acceptance criteria

• We migrate from Vuex to Pinia

Notes

• Here's the Vuex to Pinia migration guide for reference
• Considerations for the migration:
• Typescript incompatibilities are fixed
• Relevant code points are updated
