@leichtgewicht/ip-codec
Small package to encode or decode IP addresses from buffers to strings. Supports IPV4 and IPV6.
Usage
The basics are straigthforward
1import { encode, decode, sizeOf, familyOf } from '@leichtgewicht/ip-codec' 2 3const uint8Array = encode("127.0.0.1") 4const str = decode(uint8Array) 5 6try { 7 switch sizeOf(str) { 8 case 4: // IPv4 9 case 16: // IPv6 10 } 11 switch familyOf(str) { 12 case: 1: // IPv4 13 case: 2: // IPv6 14 } 15} catch (err) { 16 // Invalid IP 17}
By default the library will work with Uint8Array's but you can bring your own buffer:
1const buf = Buffer.alloc(4) 2encode('127.0.0.1', buf)
It is also possible to de-encode at a location inside a given buffer
1const buf = Buffer.alloc(10) 2encode('127.0.0.1', buf, 4)
Allocation of a buffer may be difficult if you don't know what type the buffer: you can pass in a generator to allocate it for you:
1encode('127.0.0.1', Buffer.alloc)
You can also de/encode ipv4 or ipv6 specifically:
1import { v4, v6 } from '@leichtgewicht/ip-codec' 2 3v4.decode(v4.encode('127.0.0.1')) 4v6.decode(v6.encode('::'))
History
The code in this package was originally extracted from node-ip and since improved.
Notable changes are the removal of the Buffer dependency and better support for detection of
formats and allocation of buffers.
