auto-import-extensions

Script to help with moving from webpack to vite. The script analyzes imports without file extensions and auto detects and updates the import with their extension.

This is a very barebones script that I wrote to help with upgrading our project from vue 2 and webpack to vue 3 and vite. Since vite requires all imports to have file extensions (.vue|.js, etc) and I didn't want to manually update all our imports this script auto detected the imported modules filetype and updates the import.

We only have .vue and .js files so thats all i needed to handle. this could be updated to find the file, read the ext from fs and use that instead to support more .ts, .cjs, whatever else.

This also reads your aliases from your vite.config.js which it's assuming is in the root of your project.

to run, just slap the script in your project next to your vite.config.js file and run it with node.

running

• copy paste script next to your vite.config.js if you have one, or just the root of your project.
• if your code doesn't live in src/ then you'll want to update the script to point at your path.
• node index.js will run it and output what files have been updated.

whats supported

if you have files

path/to/foo.vue
path/to/bar.js
path/to/fobar/index.js

and import them like this in vue 2 in webpack

import foo from 'path/to/foo'
import { bar } from 'path/to/bar'
import { 
  foo,
  bar
} from 'path/to/foobar'
const comp = import('path/to/foo')

The result will be vite friendly

import foo from 'path/to/foo.vue'
import { bar } from 'path/to/bar.js'
import { 
  foo,
  bar
} from 'path/to/foobar' // this will stay the same since its importing the index.js module.

const comp = import('path/to/foo.vue')
