Language: JavaScript
Resolves modules to its directory names
Provide shortcuts for your modules
In most projects we will reach this point where we use directories to logically structure our JavaScript files. Let's take a look at this example:
.
├── Button
│ ├── Button.js
│ ├── Caption.js
│ └── Icon.js
...
In this scenario, Button is the module you would want to use most of the time. Caption and Icon are only being used inside of the scope of the Button file.
Whenever you want to require a module from a file in a directory you will have two choices to import these files:
import Button from './Button/Button'. Since it this case Caption and Icon should only be used for the scope for Button. We could strive for shorter import statement that would create the illusion of stronger coupling.index.js file for each directory and mimic Node.js resolution behavior. While this shortens the import statement to import Button from './Button' increasing the coupling and decreasing moving parts, it creates additional files to maintain.Ideally, we would want short import statements without the need to create additional files that link to the file in question. And this is where rollup-plugin-named-directory comes in.
If you have been using Webpack before, this plugin is similar to https://github.com/shaketbaby/directory-named-webpack-plugin.
import namedDirectory from 'rollup-plugin-named-directory'; rollup({ plugins: [ namedDirectory() ] })
Default value: ['<dir>/<dir>.js']
Whenever Rollup encounters <dir>, it will now look for <dir>/<dir>.js first. (Example: If the directory is Button, it will now look for Button/Button.js first)
If the plugin isn't able to find the file in question, it will continue with the typical resolution behavior as dictated by Rollup and other plugins.
Make sure to provide the file extensions in.
It's possible to provide multiple strings which will be resolved in the order they have been defined.
namedDirectory({ matchers: ['<dir>CustomSuffix.js', '<dir>/<dir>.js'] })
Allows to provide an optional filter function that will be called on each potential match from the matchers array.
Default value: () => false
namedDirectory({ filter: (name: string): boolean => { // Name provides the relative path to the expanded module // ./files/Button/Button.js } })
