const gatewayTools = new IPFSGatewayTools();
```
## Usage
The IPFS gateway toolkit currently contains the following functions:
- [containsCID](#containsCID-anchor)
- [convertToDesiredGateway](#convertToDesiredGateway-anchor)
### 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:
```javascript
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
```
