bops

bops

buffer/typed array agnostic buffer operations.

var binary = require('bops')

binary.readUInt8(new Buffer(10), 0) // === 10

in browser, will default to using Uint8Array instances. in node, will default to using Buffer instances.

API

supported encodings

• utf8
• hex
• base64

bops.from(str, encoding="utf8") -> buf

given a string (and optional encoding) return a native buffer instance. also accepts arrays.

bops.to(buf, encoding="utf8") -> str

given a native buffer (and optional encoding) return a string.

bops.is(buf) -> bool

given a native buffer returns true. Returns false for other values.

bops.subarray(buf, start[, end]) -> buf

return a view onto the original buffer.

bops.join([buf, buf, buf]) -> buf

compile several buffers into a single buffer.

bops.create(size) -> buf

create a native buffer instance of size.

bops.copy(source, target, target_start, source_start, source_end)

perform a fast copy from one native buffer to another.
