feat: support ignore option for glob import

[vimcaw]

Motivation

Sometimes we need to ignore some files or directories when using import.meta.glob, such as ignoring components or utils directories, files beginning with _ or ., etc.

A typical application scenario is:

In a file-based routing system, all files starting with lowercase letters and numbers in the pages directory will be automatically imported as routers by src/pages/**/[a-z0-9]*.tsx, and the following files or directory will be ignored:

• Directories or files beginning with a capital letter (this will be regarded as a component)
• components or utils directory
• Files or directories beginning with . or _
• Type definition files ending in d.ts
• Test files ending with test.ts, spec.ts, e2e.ts

That will be difficult to achieve if only one pattern can be specified (make duplicated multiple level path rule in glob pattern is very difficult, See mrmlnc/fast-glob#306), but that can be easy if the ignore option of fast-glob can be specified.

Document

You can also pass the second argument to ignore some files:

const modules = import.meta.glob('./dir/*.js', '**/b*.*')

That will ignore all files whose name starts with b, the file ./dir/bar.js will be ignored, the above will be transformed into the following:

// code produced by vite
const modules = {
  './dir/foo.js': () => import('./dir/foo.js')
}

Seems it will be better to support multiple patterns instead of the ignore option, multiple patterns can also achieve the same effect of the ignore option and will be more powerful according to https://github.com/mrmlnc/fast-glob#ignore:

dir/
├── package-lock.json
└── package.json

fg.sync(['*.json', '!package-lock.json']);            // ['package.json']
fg.sync('*.json', { ignore: ['package-lock.json'] }); // ['package.json']

I will try to support multiple patterns.

Oops, this PR lacks some processing of HMR, I will add them when I have time.

It will be helpful for me, to write like

import.meta.glob(`./**/index.vue`, { deep: 1 })

[hyf0]

I will suggest only support pattern like import.meta.glob('...', { ignore: ['....'] }) for better flexibility and consistency.

[hyf0]

Should we also overwrite the default ignore option if the user explicit set ignore option. In that case, we could also close #1903 by import.meta.glob('...', { ignore: [] }).

[hyf0]

The other solution of #1903 would be something like import.meta.glob('...', { node_modules: true })

[vimcaw]

Ok, I will implement it later.

[vimcaw]

I think we should leave a ignoreNodeModules option (like your second solution) to support this, otherwise, the user will have to manually add the node_modules item every time the ignore option is used.

[hyf0]

Yes, I'm also prefer option like import.meta.glob('...', { node_modules: true }). We don't need to solve #1903 in this PR. Maybe it's better to let the vite team consider weather should and how to support the feature in #1903.

Close in favor of #7537 (targeting v3.0)
