How to use vue-chartjs with unplugin-vue-components?

I try to use unplugin-vue-components to automatically import Vue components from vue-chartjs, but I don't know how.

I found this in unplugin-vue-components documentation:

You can also write your own resolver quickly:

Components({
  resolvers: [
    // example of importing Vant
    (componentName) => {
      // where `componentName` is always CapitalCase
      if (componentName.startsWith('Van'))
        return { name: componentName.slice(3), from: 'vant' }
    },
  ],
})

But since components from vue-chartjs don't come with a common prefix, like CBar or ChartBar, I have no idea how to config unplugin-vue-components.

The following will import all charts from vue-chartjs and prefix them with "C":

import Components from 'unplugin-vue-components/vite'
const charts = [
  'Bar',
  'Bubble',
  'Doughnut',
  'Line',
  'Pie',
  'PolarArea',
  'Radar',
  'Scatter'
]

Components({
  resolvers: [
    (name) => {
      if (charts.includes(name)) {
        return { name: `C${name}`, from: 'vue-chartjs' }
      }
    }
  ]
})

CBar, CBubble, CDoughnut etc... are now available without importing them.

Feel free to remove the charts you don't use from the names array.

Note: you don't need a common prefix in order to auto-import components using unplugin. If you change the return line to:

   return { name, from: 'vue-chartjs' }

in the above example, the charts will be auto-imported with their original names.
