File Downloads

Download a file, text, blob, etc programmatically with JavaScript, or download from a url without JavaScript

With JavaScript

typescriptjavascript
export const download = (
  content: string | Blob | File,
  fileName: string,
  type?: string
) => {
  const blob =
    typeof content === 'string' ? new Blob([content], { type }) : content
  const a = document.createElement('a')
  a.href = URL.createObjectURL(blob)
  a.download = fileName
  a.rel = 'noopener'
  a.dispatchEvent(new MouseEvent('click'))
}
export const download = (content, fileName, type) => {
  const blob =
    typeof content === 'string' ? new Blob([content], { type }) : content
  const a = document.createElement('a')
  a.href = URL.createObjectURL(blob)
  a.download = fileName
  a.rel = 'noopener'
  a.dispatchEvent(new MouseEvent('click'))
}

Info

  • We use a.dispatchEvent over a.click since some browsers don't start the download when a.click is called.

Without JavaScript

html
<a href="{{url}}" download="{{fileName}}">Click me to download!</a>

Warning

  • The url must point to a resource on the same domain and should only contain the path. e.g. if the domain you're on is soorria.com to download https://soorria.com/og.png, the url should be /og.png
