Take a look at `lib/ResolveFactory.js` to understand how everything fits together. It provides a `createResolver(options)` function and these are the possible options:
|
||
|
|
|
||
|
|
| Field | Default | Description |
|
||
|
|
| ------------------------ | --------------------------- | ---------------------------------------------------------------------------------- |
|
||
|
|
| modules | ["node_modules"] | A list of directories to resolve modules from, can be absolute path or folder name |
|
||
|
|
| descriptionFiles | ["package.json"] | A list of description files to read from |
|
||
|
|
| plugins | [] | A list of additional resolve plugins which should be applied |
|
||
|
|
| mainFields | ["main"] | A list of main fields in description files |
|
||
|
|
| aliasFields | [] | A list of alias fields in description files |
|
||
|
|
| mainFiles | ["index"] | A list of main files in directories |
|
||
|
|
| extensions | [".js", ".json", ".node"] | A list of extensions which should be tried for files |
|
||
|

|
||

|
||

|
||
|
|
| alias | [] | A list of module alias configurations or an object which maps key to value |
|
||
|
|
| resolveToContext | false | Resolve to a context instead of a file |
|
||
|
|
| unsafeCache | false | Use this cache object to unsafely cache the successful requests |
|
||
|
|
| cachePredicate | function() { return true }; | A function which decides wheter a request should be cached or not. An object is passed to the function with `path` and `request` properties. |
|
||
|
|
| fileSystem | | The file system which should be used |
|
||
|
|
| resolver | undefined | A prepared Resolver to which the plugins are attached |
|
||
|

The options are passed from the `resolve` key of your webpack configuration e.g.:
|
||
|
|
|
||
|
|
```
|
||
|
|
resolve: {
|
||
|
|
extensions: ['', '.js', '.jsx'],
|
||
|
|
modules: ['src', 'node_modules'],
|
||
|
|
plugins: [new DirectoryNamedWebpackPlugin()]
|
||
|
|
...
|
||
|
|
},
|
||
|
|
```
