    cid: (string) - The CID that the url contains if "containsCid" is true
}

convertToDesiredGateway

ipfsGatewayTools.convertToDesiredGateway(sourceUrl, desiredGatewayPrefix)

Params

• sourceUrl - A gateway url that should take one of the following forms:
  • ipfs://CID
  • ipfs://ipfs/CID
  • https://example-gateway.com/ipfs/CID
  • https://example-gateway.com/ipfs/CID/exampleFile.json

const desiredGatewayPrefix = "https://mygateway.mypinata.cloud";
const convertedGatewayUrl = ipfsGatewayTools.convertToDesiredGateway(
  sourceUrl,
  desiredGatewayPrefix
);

//In the example above, the resulting value for convertedGatewayUrl would be: https://mygateway.mypinata.cloud/ipfs/bafybeifx7yeb55armcsxwwitkymga5xf53dxiarykms3ygqic223w5sk3m
