Matters IPNS Site Generator

Matters IPNS Site Generator is currently used by matters.town, to genereate HTML files of article & user homepage & static activitypub files before adding to IPFS & IPNS.

It can be used to create encrypted HTML page with decryption code embedded, generate HTML bundle, and create content metadata.

Installation

NPM

npm install --save @matters/ipns-site-generator

Usage

Create HTML bundle for uploading to IPFS

makeArticlePage returns an array of object that contains path and buffer data that can be added with IPFS API directly. See test for more detail.

import { makeArticlePage } from '@matters/ipns-site-generator'

const article = {
  meta: { ... },
  byline: { ... },
  rss: { ... },
  article: { ... },
}

// this creates an array of object containing path and buffer data,
// which IPFS recognizes as a folder
const { bundle } = await makeArticlePage(article)

Create an encrypted HTML

Pass in a HTML string as content, and return a HTML string with the content encrypted and the encrytion key. The returned HTML can be then written to a file or add to IPFS. During rendering, the HTML will be decrypted by adding key=${encrytion-key} in query parameter, and also include a simple UI to prompt key enter.

Support payment pointer for Web Monetization. See test for more detail.

import { makeArticlePage } from '@matters/ipns-site-generator'

const { bundle, key } = await makeArticlePage({
  encrypted: true, // argument for whether encrypt or not, if false returned key will be null
  paymentPointer: '$pay-me', // used for Web Monetization
  meta: { ... },
  byline: { ... },
  rss: { ... },
  article: { ... },
})

Create HTML bundle for user homepage & static activitypub files

import { 
  HomepageContext,
  makeHomepageBundles,
  makeActivityPubBundles,
} from '@matters/ipns-site-generator'

const context: HomepageContext = {
  meta: { title, description, authorName, siteDomain, image, ... },
  byline: { author: { userName, displayName, ipnsKey, webfDomain, }, ... },
  rss: { ... },
  articles: [ { id, title, createdAt, ... }, ... ],
}

const contents = [
  ...makeHomepageBundles(context),
  ...makeActivityPubBundles(context),
]

const bundles = await ipfs.addAll(contents) // get the top dir CID

Unit test

Run test with:

npm run test

Tests were run with Jest after compiled to JavaScript. Most test are run with snapshots located in src/__tests__/__snapshots__.

Encryption with formatHTML changes in every run, since encryption is random, and we cannot use snapshot. Therefore the test write out a HTML file to src/__tests__/__snapshots__ with decryption key as filename. You can open and test the decryption manually.
