API

readAsDataURL :: Stream File → Stream Event

import {readAsDataURL} from 'most-file-reader'
import {change} from '@most/dom-event'
import {from} from 'most'
const filesStream = change(document.body)
    .chain(event => from(event.target.files).filter(file => file.type.match('image')))
readAsDataURL(filesStream)
    .observe(console.info.bind(console))

or fluently with thru

import {readAsDataURL} from 'most-file-reader'
import {change} from '@most/dom-event'
import {from} from 'most'
change(document.body)
    .chain(event => from(event.target.files).filter(file => file.type.match('image')))
    .thru(readAsDataURL)
    .observe(console.info.bind(console))

readAsDataURL will output a ProgressEvent which contains a base64 encoded url.

readAsArrayBuffer :: Stream File → Stream Event

readAsArrayBuffer will output a ProgressEvent which contains a ArrayBuffer of file data.

readAsText :: Stream File → Stream Event

readAsText will output a ProgressEvent which contains a text string of the file contents.

fileReader :: String → Stream File → Stream Event

fileReader is the underlying method for the above functions.

import {fileReader} from 'most-file-reader'
import {change} from '@most/dom-event'
import {from} from 'most'
const fileStream = change(document.body)
    .chain(event => from(event.target.files))
fileReader('readAsDataURL', fileStream)
    .observe(console.info.bind(console))
