// css to be processed
var css = fs.readFileSync("input.css", "utf8")
// process css
var output = postcss()
.use(rebaser({
assetsPath: "assets/imported", // new path for all assets
relative: true // is assetsPath relative to .css position.
//By default its relative to process.cwd()
}))
.use(reporter)

Options
assetsPath (required)
Type: String
Path to place assets to
relative (optional)
Type: Boolean
Default: False
Is assetsPath relative to .css position. By default its relative to process.cwd()
keepStructure (optional)
Type: Boolean
Default: False
To keep folder structure or not. By default all assets paths are collected flatly in assetsPath folder.
If you set this flag to true, folder structure relative to process.cwd() would be saved.
So then example above would generate following files:
|-- dist
|-- index.css
|-- assets
|-- imported
|-- assets
|-- img.jpg
|-- src
|-- stylesheet
|-- another-assets
|-- another-img.jpgrenameDuplicates (optional)
Type: Boolean
Default: False
If there are assets with different paths but same name, they would be renamed using name_% pattern.
By default only first asset would be copied.
