@hummhive/react-web-data v1.0.22

hummhive-react-web-data

Power your React site with public and/or encrypted members-only data from HummHive.

This package abstracts all the encryption, decryption, public/private key generation and HummHive data-bridge calls into a React Context Object that contains:

1. A HummHive state object
2. Actions to fetch or create data
3. A set of React Hooks to simplify usage of encrypted blob data.

Installation

1. Install with npm install @hummhive/react-web-data

Usage Examples

Using state

import React, { useContext } from 'react';
import { HummContext } from '@hummhive/react-web-data';

const MyComponent = () => {
  const { state } = useContext(HummContext);

  return <h1>Hello {state.hive.name}</h1>;
};

Fetching state

import React, { useEffect, useContext } from 'react';
import { HummContext } from '@hummhive/react-web-data';

const MyComponent = () => {
  const { state, actions } = useContext(HummContext);

  // fetch hive data when the component mounts
  useEffect(() => {
    if (!state.hive) actions.getHive();
  }, []);

  if (!state.hive) return <p>Loading...</p>;

  return <h1>Hello {state.hive.name}</h1>;
};

Joining a Hive

import React, { useEffect, useContext, useState } from 'react';
import { HummContext } from '@hummhive/react-web-data';

const MyComponent = () => {
  const { state, actions } = useContext(HummContext);
  const [error, setError] = useState(null);

  const handleJoin = async () => {
    try {
      await actions.joinHive(state.hive, USERNAME, EMAIL, GROUP_ID);
    } catch (err) {
      setError(err.message);
    }
  };

  return <button onClick={handleJoin}>Join</button>;
};

The State Object

const { state } = useContext(HummContext);

The state object contains all the data you need to build a HummHive website.

Types

type Hive = {
  name: string;
  description: string;
  signingPublicKey: string;
  encryptionPublicKey: string;
  createdAt: string;
  updatedAt: string;
};

type Member = {
  id: string;
  email: string;
  username: string;
  hive: string;
  role: string;
  groups: Array<GroupMembership>;
  encryptionPublicKey: string;
  signingPublicKey: string;
  createdAt: string;
  updatedAt: string;
};

type GroupMembership = {
  expiration: string;
  groupId: string;
  intervalCount: bigint;
  joinedAt: string;
};

type Group = {
  id: string;
  name: string;
  description: string;
  amount: bigint;
  currency: string;
  interval: string;
  isActive: boolean;
};

type StoryIndex = {
  id: string;
  title: string;
  slug: string;
  createdAt: string;
  updatedAt: string;
  publishedAt: string;
  summary: string;
};

type Stories = {
  [storyId: string]: Story;
};
type Story = {
  id: string;
  title: string;
  slug: string;
  createdAt: string;
  updatedAt: string;
  publishedAt: string;
  summary: string;
};

type MemberKeys = {
  signing: KeyPair;
  encryption: KeyPair;
};

type KeyPair = {
  public: ByteArray;
  secret: ByteArray;
};

type ByteArray = Array<bigint>;

type MemberKeysBase64 = {
  signing: KeyPairBase64;
  encryption: KeyPairBase64;
};

type KeyPairBase64 = {
  public: string;
  secret: string;
};

Actions

const { actions } = useContext(HummContext);

The actions object contains all the functions you need in order to hydrate the state object, join a Hive, login and logout.

getHive(): Promise<void>

joinHive(hive: Hive, username: string, email: string, groupId: string): Promise<void>

getMe(): Promise<void>

getGroups(): Promise<void>

login(base64KeySet: string): Promise<void>

logout(): Promise<void>

getStoryIndex(): Promise<void>

getStory(id: string): Promise<void>

Hooks

import { HummHooks } from '@hummhive/react-web-data';

Currently the only available hook is useBlob. This handles the fetching and decryption of blobs within a component.

useBlob(filename: string): { blob: DOMString, isLoading: boolean, error: string }
