Methods
catch(onRejected) → {Promise}
- Source:
Processes input CSS through synchronous and asynchronous plugins and calls onRejected for each error thrown in any plugin.
It implements standard Promise API.
Example
postcss([cssnext]).process(css).then(result => {
console.log(result.css)
}).catch(error => {
console.error(error)
})Parameters:
| Name | Type | Description |
|---|---|---|
onRejected |
onRejected | Callback will be executed on any error. |
Returns:
Promise API to make queue.
- Type
- Promise
finally(onFinally) → {Promise}
- Source:
Processes input CSS through synchronous and asynchronous plugins and calls onFinally on any error or when all plugins will finish work.
It implements standard Promise API.
Example
postcss([cssnext]).process(css).finally(() => {
console.log('processing ended')
})Parameters:
| Name | Type | Description |
|---|---|---|
onFinally |
onFinally | Callback will be executed on any error or when all plugins will finish work. |
Returns:
