Files

Select files. Download files. Work with file content.

Maybe you generate an SVG floorplan or a PDF legal document? You can use File.Download to save those files to disk. Maybe you want people to upload a GIF cat picture or a JPG waterfall? You can use File.Select to get those files into the browser.

This package does not allow arbitrary access to the file system though. Browsers restrict access to the file system for security. Otherwise, any website on the internet could go try to read private keys out of ~/.ssh or whatever else they want!

Example

Maybe you want users to select a ZIP file for you:

import File.Select as Select

type Msg
  = ZipRequested
  | ZipLoaded File

selectZip : Cmd Msg
selectZip =
  Select.file ["application/zip"] ZipLoaded

Or maybe you want people to download the floorplan they just designed as an SVG file:

import File.Download as Download

download : String -> Cmd msg
download svgContent =
  Download.string "floorplan.svg" "image/svg+xml" svgContent
