Downloading .ics file about ics HOT 2 CLOSED

If you're using something like Express with a REST endpoint, your final response will be something like this:

res
.set(
'Content-Disposition',
'attachment; filename="${FILE_NAME}.ics"',
)
.set('Content-Type', 'text/calendar')
.status(200)
.send(ics);
}

They key is to set your HTTP headers so clients know how to handle the response (in this case, an ics text file).

The ics is either generated in a function prior to the final response code above, or perhaps loaded from a cached source (in the case of a feed you probably don't want to regenerate it on every request, so you have other mechanisms to update the feed snapshot).

from ics.

For the use case where you're generating client side, you can use the popular library downloadjs or create a simple utility function.

  function downloadFile(config: { fileContents: any; fileName: string; mimeType: string }) {
    const { mimeType, fileContents, fileName } = config
    const blob = new Blob([fileContents], { type: mimeType })
    const url = URL.createObjectURL(blob)
    const link = document.createElement('a')
    link.setAttribute('href', url)
    link.setAttribute('download', fileName)
    document.body.appendChild(link)
    link.click()
    document.body.removeChild(link)
  }
  
  // ...
downloadFile({
    mimeType: 'text/calendar',
    fileContents: value,
    fileName: 'meeting.ics',
})
