Extract css class names from required css module files for TypeScript. This plugin is based on [css-modules-require-hook](https://github.com/css-modules/css-modules-require-hook) and so constructor opts are from that repo.

This allows you to do this in TS files:

```ts

// Import works

import * as css from 'foo.css'

// require also works

const foo = require('foo.css')

console.log(css.foo)

```

Append this to `before` in your compilation step. See [compile.ts](https://github.com/longlho/ts-transform-css-modules-transform/blob/master/compile.ts#L30-L32) for more info.

Right now named imports will not work due to TS mangling import name after compilation.

```ts

// Those are NOT working

import css from 'foo.css'

import { button, badge } from 'foo.css'

```

## Options

See [css-modules-require-hook](https://github.com/css-modules/css-modules-require-hook#tuning-options) for a list of options.

### Custom Options

`tsImportResolver (path: string): string`: This callback function allows you to override import path in `ImportDeclaration` for every CSS file we encounter. This is useful when dealing with project that uses `paths` aliases in tsconfig. This might not be necessary once https://github.com/Microsoft/TypeScript/issues/28276 is resolved.

## Caveats

1. Source map support might not be entirely accurate
