Support mts / cts / cjs config files

[sxzz]

Clear and concise description of the problem

Import ESM-only package in vitest.config.ts

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /Users/kevin/Developer/open-source/unplugin-jsx-string/node_modules/estree-walker/package.json

If I change extname to mts, Vitest can't find and load this config file.

Suggested solution

vitest/packages/vitest/src/constants.ts

Lines 11 to 18 in 5dca4ed

	export const configFiles = [
	'vitest.config.ts',
	'vitest.config.js',
	'vitest.config.mjs',
	'vite.config.ts',
	'vite.config.js',
	'vite.config.mjs',
	]

 export const configFiles = [ 
      'vitest.config.ts', 
+++   'vitest.config.mts', 
+++   'vitest.config.cts', 
      'vitest.config.js', 
      'vitest.config.mjs', 
+++   'vitest.config.cjs', 
      'vite.config.ts', 
+++   'vite.config.mts', 
+++   'vite.config.cts', 
      'vite.config.js', 
      'vite.config.mjs', 
+++   'vite.config.cjs', 
 ]

Does Vite support vite.config.mts/vite.config.cts?

[sxzz]

Not supported ATM, vitejs/vite#5201

[sxzz]

So, we need wait supporting of Vite. Right?

[sheremet-va]

You can open PR to both :P

[sxzz]

Wait PR vitejs/vite#8729

with vitest 0.18.0

[sheremet-va]

What Vite 3 version are you using?

[capaj]

I don't have vite as direct dependency-it's a node.js backend app.
