Spheron

Storage SDK

🧰 SDK for multi-chain storage, powered by Spheron.

Upload Example

In the example below you can see how to create an instance of SpheronClient and how to upload a file/directory to the specified protocol.

import { SpheronClient, ProtocolEnum } from "@spheron/storage";

const client = new SpheronClient({ token });
let currentlyUploaded = 0;
const { uploadId, bucketId, protocolLink, dynamicLinks, cid } =
  await client.upload(filePath, {
    protocol: ProtocolEnum.IPFS,
    name,
    onUploadInitiated: (uploadId) => {
      console.log(`Upload with id ${uploadId} started...`);
    },
    onChunkUploaded: (uploadedSize, totalSize) => {
      currentlyUploaded += uploadedSize;
      console.log(`Uploaded ${currentlyUploaded} of ${totalSize} Bytes.`);
    },
  });
  • Function upload has two parameters client.upload(filePath, configuration);
    • filePath - the path to the file/directory that will be uploaded
    • configuration - an object with parameters:
      • configuration.name - represents the name of the bucket on which you are uploading the data.
      • configuration.protocol - a protocol on which the data will be uploaded. The supported protocols are [ ARWEAVE, IPFS, FILECOIN].
      • configuration.onUploadInitiated - optional - callback function (uploadId: string) => void. The function will be called once, when the upload is initiated, right before the data is uploaded. The function will be called with one parameter, uploadId, which represents the id of the started upload.
      • configuration.onChunkUploaded - optional - callback function (uploadedSize: number, totalSize: number) => void. The function will be called multiple times, depending on the upload size. The function will be called each time a chunk is uploaded, with two parameters. the first one uploadedSize represents the size in Bytes for the uploaded chunk. The totalSize represents the total size of the upload in Bytes.
    • The response of the upload function is an object with parameters:
      • uploadId - the id of the upload
      • bucketId - the id of the bucket
      • protocolLink - is the protocol link of the upload
      • dynamicLinks - are domains that you have setup for your bucket. When you upload new data to the same bucket, the domains will point to the new uploaded data.
      • cid - the CID of the uploaded data. Only exists for IPFS and Filecoin protocols.

IPNS Example

In the example below you can see how to publish an upload to IPNS, update IPNS to another upload id and get all IPNS names for an organization.

import { SpheronClient, ProtocolEnum } from "@spheron/storage";

const client = new SpheronClient({ token });
let currentlyUploaded = 0;
const { uploadId, bucketId, protocolLink, dynamicLinks, cid } =
  await client.upload(filePath, {
    protocol: ProtocolEnum.IPFS, // Only works with IPFS and Filecoin uploads
    name,
    onUploadInitiated: (uploadId) => {
      console.log(`Upload with id ${uploadId} started...`);
    },
    onChunkUploaded: (uploadedSize, totalSize) => {
      currentlyUploaded += uploadedSize;
      console.log(`Uploaded ${currentlyUploaded} of ${totalSize} Bytes.`);
    },
  });

// Publish Upload to IPNS
const ipnsData: IPNSName = await client.publishIPNS(uploadId);

// Upload second file to Spheron
const uploadIdTwo = await client.upload(filePath2, { ...uploadDetails });

// Update IPNS Name to point to another upload
const ipnsData: IPNSName = await client.updateIPNSName(
  ipnsData.id,
  uploadIdTwo
);

// Get all published IPNS Names for organization
const orgIPNSNames: IPNSName[] = await client.getIPNSNamesForOrganization(
  organizationId
);
  • Function publishIPNS has one parameter client.upload(uploadId);
    • uploadId - the upload id of file uploaded using Spheron SDK
  • Function updateIPNSName has two parameters client.updateIPNSName(ipnsNameId, uploadId);
    • ipnsNameId - the IPNS name id of a previously published upload
    • uploadId - the new upload id you want IPNS Name to point to.
  • Function orgIPNSNames has one parameter client.upload(organizationId);
    • organizationId - your organization id

The SpheronClient instance provides several methods for working with buckets. The supported methods are:

  • async getBucket(bucketId: string): Promise<Bucket>
    • used to get the bucket information for the specified bucketId.
  • async getBucketDomains(bucketId: string): Promise<Domain[]>
    • used to get the domains that are attached to the specified bucketId.
  • async getBucketDomain(bucketId: string, domainIdentifier: string): Promise<Domain>
    • used to get the information about the specific domain. The domainIdentifier can ether be the id of the domain, or the name of the domain.
  • async addBucketDomain(bucketId: string, { link: string; type: DomainTypeEnum; name: string; }): Promise<Domain>
    • used to add a new domain to the specified bucket. The link property needs to have the protocolLink value of an existing bucket id. After adding a new domain, you will need to setup the record on your DNS provider:
      • domain: you should create a A type record with value 13.248.203.0, and the same name as the domain you have added.
      • subdomain : you should create a CNAME type record with value cname.spheron.io, and the same name as the domain you have added.
      • handshake-domain: you should create a A type record with value ipfs.namebase.io, and @ for name. Also you should create a TXT type record with link for a value, and _contenthash for name.
      • handshake-subdomain: you should create a A type record with value ipfs.namebase.io, and the same name as the domain you have added. Also you should create a TXT type record with link for a value, and _contenthash.<name_of_the_domain> for name.
      • ens-domain: you should create a CONTENT type record with link for a value, and the same name as the domain you have added.
    • After you have setup the record on your DNS provider, then you should call the verifyBucketDomain method to verify your domain on Spheron. After the domain is verified, the data behind the link will be cached on the Spheron CDN.
  • async updateBucketDomain(bucketId: string, domainIdentifier: string, options: { link: string; name: string; }): Promise<Domain>
    • used to update an existing domain of the Bucket.
  • async verifyBucketDomain(bucketId: string, domainIdentifier: string): Promise<Domain>
    • used to verify the domain, after which the content behind the domain will be cached on CDN.
  • async deleteBucketDomain(bucketId: string, domainIdentifier: string): Promise<void>
    • used to delete the domain of the Bucket.
  • async archiveBucket(bucketId: string): Promise<void>
    • used to archive the Bucket. New uploads cannot be created for an archived bucket.
  • async unarchiveBucket(bucketId: string): Promise<void>
    • used to unarchive the Bucket.
  • async getBucketUploadCount(bucketId: string): Promise<{total: number; successful: number; failed: number; pending: number; }>
    • used to get the number of uploads for the specified bucket.
  • async getBucketUploads(bucketId: string, options: { skip: number; limit: number; }): Promise<Upload[]>
    • used to get the uploads of the bucket. The default value for skip is 0. The default value for limit is 6.
  • async getUpload(uploadId: string): Promise<Upload>
    • used to get the upload by its id.
  • async getOrganizationUsage(organizationId: string): Promise<UsageWithLimits>
    • used to get the usage of the current active subscription of the organization.
  • async getTokenScope(): Promise<TokenScope>
    • used to get the scope of the token.
  • async publishIPNS(uploadId: string): Promise<IPNSName>
    • used to publish IPFS Upload to IPNS
  • async updateIPNSName(ipnsNameId: string, uploadId: string): Promise<IPNSName>
    • used to update IPNS name to new upload id
  • async getIPNSName(ipnsNameId: string): Promise<IPNSName>
    • get IPNS name data by id
  • async getIPNSNamesForUpload(uploadId: string): Promise<IPNSName[]>
    • get all IPNS names for an upload id
  • async getIPNSNamesForOrganization(organizationId: string): Promise<IPNSName[]>
    • get all IPNS names for an organization
  • async createSingleUploadToken(configuration: { name: string; protocol: ProtocolEnum; }): Promise<{ uploadToken: string }>
    • used to create a token for the @spheron/browser-upload package. The token can be used by your web app to enable users to directly upload their data from their browser to the specified protocol. Checkout the @spheron/browser-upload package for more information.

  publishedUploadId: string;
  organizationId: string;
  createdAt: string;
  updatedAt: string;

  ipnsLink: string;
}

The package also provides a couple of methods for transforming CID from V0 to V1 and vice verse.

import { ipfs } from "@spheron/storage";

const cid = <CID_VALUE>;

const v1 = ipfs.utils.toV1(cid);
console.log("CID V1", v1);

const v0 = ipfs.utils.toV0(cid);
console.log("CID V0", v0);

Access Token

To create the token that is used with the SpheronClient, follow the instructions in the DOCS. When you are creating the tokens, please choose web app type in the dashboard.

Notes

The package is only meant for Node.js environments and will not work in a browser or frontend apps.
