All hex string inputs can be prefixed with
0x
, but it's not mandatory.

This function takes a content hash as a hex string and returns the decoded content as a string.
import { decode } from "@ensdomains/content-hash";
const encoded =
"e3010170122029f2d17be6139079dc48696d1f582a8530eb9805b561eda517e22a892c7e3f1f";
const content = decode(encoded);
// 'QmRAQB6YaCyidP37UdDnjFY5vQuiBrcqdyoW1CuDgwxkD4'
This function takes a supported codec as a string and a value as a string and returns coresponding content hash as a hex string.
import { encode } from "@ensdomains/content-hash";
const onion = "zqktlwi4fecvo6ri";
const encoded = encode("onion", onion);
// 'bc037a716b746c776934666563766f367269'
This function takes a content hash as a hex string and returns the codec as a hex string.
import { getCodec } from "@ensdomains/content-hash";
const encoded =
"e40101701b20d1de9994b4d039f6548d191eb26786769f580809256b4685ef316805265ea162";
const codec = getCodec(encoded);
// 'swarm'
This function takes an ipfsHash and converts it to a CID v1 encoded in base32.
import { cidV0ToV1Base32 } from "@ensdomains/content-hash";
const ipfs = "QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG";
const cidV1 = cidV0ToV1Base32(ipfs);
// 'bafybeibj6lixxzqtsb45ysdjnupvqkufgdvzqbnvmhw2kf7cfkesy7r7d4'
This function takes any ipfsHash and converts it to DNS-compatible CID.
import { cidForWeb } from "@ensdomains/content-hash";
const ipfs = "QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG";
const cidV1 = cidForWeb(ipfs);
// 'bafybeibj6lixxzqtsb45ysdjnupvqkufgdvzqbnvmhw2kf7cfkesy7r7d4'
