Vue-BridgeDependency Management
You want to to have a proper setup, which allows you to write, run, test and build your library reliably for Vue 2 and Vue 3. To do this, you will need a bunch of dependencies related testing and building:
| Dependency | Vue 2 | Vue 3 | Notes |
|---|---|---|---|
vue | ^2.6 | ^3 | Hoisting to root easily causes problems. PNPM's strictness helps here. |
@vue/test-utils | ^1.0 | ^2.0 | Installing both versions with packages aliases is flaky. Workspaces are more reliable. |
@vitejs/plugin-vue | ❌ | ✅ | |
vite-plugin-vue2 | ✅ | ❌ | |
vue-template-compiler | ^2.6 | ❌ | Breaks if vue package is not a matching version |
While it is probably technically possible to install all of these into a project with one package.json using package alias names and such,this approach is complicated and brittle, in our experience. In a workspace setup, you can separate these dependencies into their own package.json files and keep them separate.
