Hashed Private Client API

Enables the usage of the Hashed Private backend services by client applications.

To install the hashed private client api run the following command:

npm i --save @smontero/hashed-private-client-api

Access to most of the functionality is done through the HashedPrivate object which enables its configuration and provides access to the different API objects:

import { HashedPrivate } from '@smontero/hashed-private-client-api'

A new instance of the HashedPrivate class has to be created passing in the ipfs url, hashed private server endpoint and the sigining function:

const hp = new HashedPrivate({
    ipfsURL: 'https://ipfs.infura.io:5001',
    privateURI: 'http://localhost:8080/v1/graphql',
    signFn: async (address, message) => {
      const { signature } = await nbvStorageApi.signMessage(message, address)
      return signature
    }
})

Then the user has to be logged in into the hashed private server:

await hp.login(address)

Once logged in the services provided by the Document and Group objects can be accessed.

Document services

• store: Store a personal private document in the hashed private service

const document = await hp.document().store({
    name: 'name1',
    description: 'desc1',
    payload: {
      prop1: 1,
      prop2: 'str1'
    }
  })

This method receives an optional actorId parameter that can be used to store a document on behalf of a group

• share: Share a private document with another user or group

const document = await hp.document().share({
    toActorAddress: '5CBLWNtpdafzuUsq7P5Hn4amrBAd66R183FmHkEC7utB28ni'
    name: 'name1',
    description: 'desc1',
    payload: {
      prop1: 1,
      prop2: 'str1'
    }
  })

This method receives an optional actorId parameter that can be used to store a document on behalf of a group

• viewByCID: View a stored payload by specifying the cid, returns the deciphered payload(object or File)

const document = await hp.document().viewByCID({cid})

• updateMetadata: Update the metadata for a document

const document = await hp.document().updateMetadata({
    cid,
    name,
    description
  })

• delete: Delete a document by specifying the cid
