`import` now works with directories
npm install babel-plugin-wildcardAllows you to import all files from a directory at compile-time.
``sh`
$ npm install babel-plugin-wildcard
.babelrc
`json`
{
"plugins": ["wildcard"]
}
`sh`
$ babel --plugins include script.js
`javascript`
require('babel').transform('code', {
plugins: ['wildcard']
});
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)
- File extensions are removed in the resulting variable. Dotfiles will be imported without their preceding . (e.g. .foo -> Foo or foo depending on settings)import { ... } from 'foo/*'
- in an , 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).
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:
, 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.$3
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).$3
By default the name is converted to PascalCase, if you prefer camelCase, you may set this option to true:`
{
plugins: [
['wildcard', {
'useCamelCase': true
}]
]
}
`$3
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").
