static

  • static(sourcePath: string, options?: StaticOptions): this
  • Adds routes for all static assets in a directory tree.

    Example

     router.static('public')

    To only serve files matching a particular pattern, use the glob options:

     router.static('public', {
       glob: '*.css'
     })

    By default the path on which files are served corresponds to the path within the directory, so for example, public/css/main.css would be served at '/css/main.css', you can override this using the path option:

     router.static('public', {
       paths: file => ['/assets/ + file] // will serve public/css/main.css at /assets/css/main.css
     })

    You can add caching or other additional handler logic using the handler option:

     router.static('public', {
       handler: (file) => ({ cache }) => {
         cache({
           browser: {
             maxAgeSeconds: 60 * 60
           },
           edge: {
             maxAgeSeconds: 60 * 60 * 24,
             staleWhileRevalidateSeconds: 60 * 60
           }
         })
       }
     })

    Parameters

    • sourcePath: string

    • Default value options: StaticOptions = {}
