make-base64

Encode strings and binary data as Base64 with configurable symbols and padding.

Usage

import makeBase64 from 'make-base64'

makeBase64('hello') // 'aGVsbG8'
makeBase64('hello', {pad: true}) // 'aGVsbG8='

makeBase64(new Uint8Array([251, 255])) // '-_8'
makeBase64(new Uint8Array([251, 255]), {symbols: 'base64'}) // '+/8'
makeBase64(new Uint8Array([251, 255]), {symbols: ['.', '~']}) // '.~8'

makeBase64('f', {pad: '.'}) // 'Zg..'

Options

| Option | Type | Default | Description | | --- | --- | --- | --- | | pad | boolean \| string | false | Pad to a multiple of 4 symbols. true uses =; a string uses that string. | | symbols | [string, string] \| 'base64' \| 'base64url' | 'base64url' | Symbols for digits 62 and 63, or a predefined symbol set. |
