[Bug report] Can not load file without extname in public folder

[YunYouJun]

Describe the bug

When i upgrade vite from v1.0.0-rc.13 to v2.0.0-beta.4, i can not load file (without extname) in public folder.

For example, i can not load file called abc, but i can load the same file called abc.data.

4:01:26 PM [vite] Internal server error:
  Error: Failed to load url /weights/ssd_mobilenetv1_model-shard1. Does the file exist?
      at transformRequest (/Users/yunyou/github/lab/vtuber/node_modules/vite/dist/node/chunks/dep-d7654bd1.js:67089:15)

Reproduction

Just create a file called test and a file called test.json in public folder, then ask it.

System Info

• required vite version: v2.0.0-beta.4
• required Operating System: macOS 11.1
• required Node version: v12.14.1

2.0.0-beta.5 也有这个问题

This is expected behavior. Everything in public must be referenced with explicit extensions in 2.0.

Also, files inside public should not be imported from JS. They can only be referenced via direct asset references like <img src> or <link href>.

Thank you for your answer. I read the description of vite docs.

The public Directory

If you have assets that are:

• ...or you simply don't want to have to import an asset first just to get its URL

I use face-api.js by vite. So I put the model under public.

It is a lib needs to load some models. Because the model is too large, the model is typically split into small files and loaded through js.

For example:

.
├── ssd_mobilenetv1_model-shard1
├── ssd_mobilenetv1_model-shard2
└── ssd_mobilenetv1_model-weights_manifest.json

Should an option be provided for users to decide whether to allow access to files without extname?

[yyx990803]

If the lib is trying to load extension-less files under public by XHR it should work. If you think this is a bug, you need to provide an actual reproduction.

I create a demo project vite-bug-report-1364. The detailed steps are described in the README.
