# babel-plugin-wildcard
Allows you to `import` all files from a directory at compile-time.
## Installation
```sh
$ npm install babel-plugin-wildcard
```
## Usage
### Via `.babelrc` (Recommended)
**.babelrc**
```json
{
"plugins": ["wildcard"]
}
```
### Via CLI
```sh
$ babel --plugins include script.js
```
### Via Node API
```javascript
require('babel').transform('code', {
plugins: ['wildcard']
});
```
## Example
With the following folder structure:
```
|- index.js
|- dir
|- a.js
|- b.js
|- c.js
```
the following JS:
```javascript
import * as Items from './dir';
```
will be compiled to:
```javascript
const Items = {};
import _wcImport from "./dir/a";
Items.A = _wcImport;
import _wcImport1 from "./dir/b";
Items.B = _wcImport1;
import _wcImport2 from "./dir/c";
Items.C = _wcImport2;
```
meaning you will be able to access the items using `Items.A` and `Items.B`.
---
You can also selectively choose files using:
```javascript
import { A, C } from "dir/*";
```
which in the above example would convert to:
```
import A from "./dir/a";
import C from "./dir/c";
```
The above is like doing:
```
import * as temp from "dir";
const { A, C } = temp;
```
---
There is also simple Glob support so given the directory structure:
```
|- index.js
|- dir
|- a.js
|- a.spec.js
|- b.js
|- b.spec.js
```
this import:
```javascript
import * as tests from './dir/*.spec';
```
will compile to:
```javascript
import aSpec from './dir/a.spec';
import bSpec from './dir/b.spec';
```
---
Files are automatically camel-cased and in the `import` statements the extensions are clipped unless specified otherwise (see below)
## Information
- File extensions are removed in the resulting variable. Dotfiles will be imported without their preceding `.` (e.g. `.foo` -> `Foo` or `foo` depending on settings)
- in an `import { ... } from 'foo/*'`, the identifiers inside { ... } are the same as what their name
would be if you were to import the whole directory. This means it is the files' names' pascal/camel-cased and extensions removed etc. by default (depending on settings of course).
## Options
`babel-plugin-wildcard` allows you to change various settings by providing an options object by using the following instead:
```javascript
{
plugins: [
['wildcard', { options }]
]
}
```
where `{ options }` is the options object. The following options are available:
### `exts`
By default, the files with the following extensions: `["js", "es6", "es", "jsx"]`, will be imported. You can change this using:
```javascript
{
plugins: [
['wildcard', {
'exts': ["js", "es6", "es", "jsx", "javascript"]
}]
]
}
```
If you add the extension `""`, it will also import subdirectories.
### `nostrip`
By default, the file extension will be removed in the generated `import` statements, you can change this using:
```javascript
{
plugins: [
['wildcard', {
'nostrip': true
}]
]
}
```
This is useful when the extension of your source files is different from the outputted ones. (e.g. `.jsx` to `.js`).
### `useCamelCase`
By default the name is converted to PascalCase, if you prefer camelCase, you may set this option to true:
```
{
plugins: [
['wildcard', {
'useCamelCase': true
}]
]
}
```
### `noModifyCase`
By default, the name will be automatically pascal cased, the following regex is used to extract the words, those words then have their first letter capitalized and are joined together:
```
[A-Z][a-z]+(?![a-z])|[A-Z]+(?![a-z])|([a-zA-Z\d]+(?=-))|[a-zA-Z\d]+(?=_)|[a-z]+(?=[A-Z])|[A-Za-z0-9]+
```
you can disable this behavior using:
```javascript
{
plugins: [
['wildcard', {
'noModifyCase': true
}]
]
}
```
Extensions are still removed (except dotfiles, see "Information").
