Package Exports

buf-b32

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (buf-b32) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

buf-b32

Converts a buffer holding binary to base32 (buf_b32 or encode); and converts a buffer or base32 string into a buffer (b32_buf or decode).

Uses loads of bitwise notation. Have fun?

2.0.0 update

only returns Uint8Arrays now.

converting a Uint8Array to a Buffer: Buffer.from(u.buffer, u.byteOffset, u.byteLength).

All internal values use Uint8Array now.

Docs

encode(buffer[, useString])

buffer: ArrayBufferView (Buffer, Uint8Array, Uint32Array, DataView etc)
useString: boolean
Returns: string | Uint8Array

When useString is true, returns string; else returns Uint8Array.

decode(buffer[, overwrite])

buffer: ArrayBufferView (Buffer, Uint8Array, Uint32Array, DataView etc)
overwrite: boolean
Returns: Uint8Array
