I am trying to upload a lot of files from S3 to IPFS via Pinata. I haven't found in Pinata documentation something like that.
This is my solution, using the form-data library. I haven't tested it yet (I will do it soon, I need to code some things).
Is it a correct approach? anyone who has done something similar?
async uploadImagesFolder(
items: ItemDocument[],
bucket?: string,
path?: string,
) {
try {
const form = new FormData();
for (const item of items) {
const file = getObjectStream(item.tokenURI, bucket, path);
form.append('file', file, {
filename: item.tokenURI,
});
}
console.log(`Uploading files to IPFS`);
const pinataOptions: PinataOptions = {
cidVersion: 1,
};
const result = await pinata.pinFileToIPFS(form, {
pinataOptions,
});
console.log(`Piñata Response:`, JSON.stringify(result, null, 2));
return result.IpfsHash;
} catch (e) {
console.error(e);
}
}
I had the same problem
So, I have found this: https://medium.com/pinata/stream-files-from-aws-s3-to-ipfs-a0e23ffb7ae5
But in the article If am not wrong, is used a different version to the JavaScript AWS SDK v3 (nowadays the most recent: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/index.html ).
This is for the Client side with TypeScript:
If you have this version, for me works this code snippet:
export const getStreamObjectInAwsS3 = async (data: YourParamsType) => {
try {
const BUCKET = data.bucketTarget
const KEY = data.key
const client = new S3Client({
region: 'your-region',
credentials: {
accessKeyId: 'your-access-key',
secretAccessKey: 'secret-key'
}
})
const resource = await client.send(new GetObjectCommand({
Bucket: BUCKET,
Key: KEY
}))
const response = resource.Body
if (response) {
return new Response(await response.transformToByteArray()).blob()
}
return null
} catch (error) {
return null
}
}
With the previous code, you can get the Blob Object for pass it to the File object with this method and get the URL resource using the API :
export const uploadFileToIPFS = async(file: Response) => {
const url = `https://api.pinata.cloud/pinning/pinFileToIPFS`
const data = new FormData()
data.append('file', file)
try {
const response = await axios.post(url, data, {
maxBodyLength: Infinity,
headers: {
pinata_api_key: 'your-api',
pinata_secret_api_key: 'your-secret'
},
data: data
})
return {
success: true,
pinataURL: `https://gateway.pinata.cloud/ipfs/${ response.data.IpfsHash }`
}
} catch (error) {
console.log(error)
return null
}
}
I have found this solution from this nice article and you can explore other implementations (including the Node.js side)
Take a look at Filebase, which offers an S3-Compatible API for storing data on IPFS!
