Save any data to file in browser or node

save-file

Save file in node/browser. In browser it prompts save file dialog, in node it creates a file.

• Provides common interface for both node/browser.
• Fixes dialog race in browser − when multiple save-files are called at the same time.
• Handles any types of input data − Buffer, ArrayBuffer, ArrayBufferView, File, Blob, data-uri string, ImageData etc.

Usage

// const save = require('save-file')
import { save } from 'save-file'

await save(data, 'example.mp3')

const saveSync = require('save-file/sync')
saveSync(otherData, 'example2.mp3')

API

await save(data|filename, filename|data)

Save data source to the filename destination, return actual saved ArrayBuffer. saveSync performs synchronous call.

data type can be:

• Buffer, ArrayBuffer
• File, Blob
• dataURI, base64 string
• TypedArray, Array
• ImageData, AudioBuffer
• Object
• ndarray
• etc.

See to-array-buffer for the full list. The data is expected to be encoded to target format, for that purpose see image-encode, audio-encode etc.

Mime type is detected from the file extension/data type automatically.
