Usage

The IPFS gateway toolkit currently contains the following functions:

containsCID

ipfsGatewayTools.containsCID(url)

Params

• url - 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
  • https://example-gateway.com/ipns/CID

Response

{
    containsCid: (Boolean) - True if the url contains a CID,
    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
  • https://example-gateway.com/ipns/CID
• desiredGatewayPrefix - The desired gateway you want to convert your source URL to. A few examples of this would be:
  • https://mygateway.mypinata.cloud
  • https://ipfs.io

Response

Returns a string that uses the desired source gateway prefix.

Example code:

const sourceUrl = 'https://exampleGateway.com/ipfs/bafybeifx7yeb55armcsxwwitkymga5xf53dxiarykms3ygqic223w5sk3m';
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
