Readme
dot-index-webpack-plugin
This plugin automatically builds dot index files that export the contents of directories. It generates these files each time a file is changed or added to a specified source folder. This relieves you of the need to remember to update your index files each time you add a new file to your project.
Dot Index Files
Dot index files are identical to index files except in name: the filename .index.js
rather than index.js
denotes that they were generated automatically. A dot index file exports all other modules in its directory, using the name of the file as the name of the export. For instance, in a directory with structure:
+ src
| - .index.js
| - myModule.js
| - otherModule.js
The .index.js file would look like:
export { default as myModule } from './myModule'
export { default as otherModule } from './otherModule'
This convention means that it's important that filenames match desired module names. In order to use a custom index file rather than a generated one, simply add a index.js
in the given directory.
Usage
To use this plugin in your project, add an instance of the plugin to your plugins
array, with a path
option value specifying the root of the directory where you'd like your dot index files to be generated.
Example webpack.config.js:
const DotIndexPlugin = require('dot-index-webpack-plugin')
module.exports = {
// ... other configuration ...
plugins: [
new DotIndexPlugin({
// watch src/ folder for changes
path: path.join(__dirname, '../src'),
}),
],
}
Custom export names
In some cases, you may want to customize the formatting of the generated export names.
In this case, you can pass in a custom formatExports
function to the plugin constructor:
plugins: [
new DotIndexPlugin({
path: path.join(__dirname, '../src'),
formatExports: (filename, rootPath) => filename.toUpperCase()
})
],
// ... will result in ...
export { default as MYCOMPONENT } from './MyComponent'
