Q & A

Why not vite-plugin-compression

• vite-plugin-compression no longer maintenance.

Why vite-plugin-compression2

• vite-plugin-compression2 has minimal dependencies and better performance.

Can i custom the compression algorithm?

• Yes, you can see the unit test case.

Can i generate multiple compressed assets with difference compression algorithm?

import { defineComponent } from 'vite'
import { compression } from 'vite-plugin-compression2'

export default defineComponent({
  plugins: [
    // ...your plugin
    compression(),
    compression({ algorithm: 'brotliCompress', exclude: [/\.(br)$/, /\.(gz)$/], deleteOriginalAssets: true })
  ]
})

• You should set exclude for the latest compression plugin. ( Because in the full bundle process. Bundle chunk is shared. And there are write (delete) operations on the bundle inside the plugin. So you should ignore the compressed chunk :) If you want delete the original assets you also follow the way.

Can i create a tarball for all of assets after compressed?

• Yes, you can import tarball plugin from this package(>=1.0.0)

import { defineComponent } from 'vite'
import { compression, tarball } from 'vite-plugin-compression2'

export default defineComponent({
  plugins: [
    // ...your plugin
    compression(),
    tarball()
  ]
})
