💪 Motivation

A CMS should not be the defining feature of a webapp. Neither should Ecommerce or anything other than your code.
ERP integration should not force developer to cut corners.

• Jaen does not interfere with your user experience.
• Jean does not challange your application design.
• Jaen gives the power back to you.

One thing and one thing only with clean and well documented interfaces. Customizable, extensible and open-source.

Jaen Features

• A fast, attractive interface for authors
• Complete control over front-end design and structure
• Fast out of the box, cache-friendly when you need it
• StreamField encourages flexible content without compromising structure
• Excellent support for images and embedded content
• Powered by blockchain and can be run for free
• Simple, intuitive "What you see is what you get" editing mode

Generate from template Generate Jaen on GitHub

Generate from template	Important public and no branches

First Deployment

The GITHUB_TOKEN has limitations for the first deployment so we have to select the GitHub Pages branch on the repository settings tab. After that follow the instrucions shown in the pictures below to deploy successfully.

First deployment failed	Go to the settings tab

Select branch	Deploying again and succeed

Deployment Options

We recomend to use vscode as IDE in either an codespace or local setup.

Codespace Setup

The easiest method is to use a GitHub Codespace (in beta). Just create a GitHub Codespace from the Code menu. Wait for the Codespace to complete provisioning. When the Codespace has completed provisioning open a terminal window (Ctrl-`, Control-backquote) and:

• Add GitHub npm registry npm login --registry=https://npm.pkg.github.com
• Create .env and set PUBLIC_URL
• Start a local copy of the docs site with npm start
• Or build a local copy of the library with npm run build

Local Setup

If you decide to set up locally, make sure you have the following prerequisites:

• Add GitHub npm registry npm login --registry=https://npm.pkg.github.com
• Use npm install to install all dependencies
• Start a local copy of the docs site with npm start
• Or build a local copy of the library with npm run build

The demo site will now be accessible at http://localhost:3000/.

Troubleshooting

If you are having trouble to get the template up and running there are a few things you can try:

• node-sass requires you to use node15. If you have node16 you can use nvm to get the repository running without having to downgrade

If you encounter any other issues getting this template to work we ask you to report it so that we can improve the documentation.

Editing

To edit the page you have to log into the CMS.
The standard user for this is snekman and the password for the account is ciscocisco.

Page Settings

Field	Type	Description	Wiki	Tutorial
PageType	string	The PageType defines the name of your page in the context of the CMS.
ChildPages	[Pages]	ChildPages is an array of pages in which you define what subpages can be added to a particular PageType.

SimplePdfField	name pdfStyle	If you want to embed a PdfFile on your page you can use our SimplePdfField.	✅️
StreamField	name reverseOrder blocks	With a StreamField you can build your own React-Components with editable content and repeat them as often as you like.	✅️
IndexField	fixedSlug outerElement renderItem	The IndexField provides you with the oppertunity to easily build links, buttons and more pointing to your subpages. It is also useful for building cards that rely on content from childpages. With the fixedSlug property you can decide which page the childpages are pulled from.	✅️

App Settings

import {CMSProvider} from '@snek-at/jaen'

import {HomePage} from '...'
import ImprintPage from '...'

const App: React.FC = () => {
  return (
    <div style={{margin: 150}}>
      <CMSProvider
        settings={{gitRemote: process.env.REACT_APP_JAEN_GIT_REMOTE}}
        pages={[HomePage, ImprintPage]}></CMSProvider>
    </div>
  )
}
)

Page Settings

import ImprintPage from '...'

const HomePage: ConnectedPageType = () => {...}

HomePage.PageType = 'HomePage'
HomePage.ChildPages = [ImprintPage]

export default HomePage

Fields

Fields are data blocks that you can use to build React apps which the enduser is able to maintain. Fieldnames have to be unique when they are on the same page. It is advisable to give all the fields descriptive names.

SimpleTextField

The SimpleTextField is as the name implies quite simple. You just have to give the field a name.

Wiki 📖

import {SimpleTextField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
    <SimpleTextField name="stffield" />
  )
}

[...]

export default HomePage

SimpleRichTextField

SimpleRichTextField is also a quite simple field that only requires a name.

Wiki 📖

import {SimpleRichTextField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
    <SimpleRichTextField name="srtffield" />
  )
}

[...]

export default HomePage

SimpleImageField

If you want to add an image to your page you can use the SimpleImageField.
It works by embedding an image that is hosted on the ipfs by the CMS.

Wiki 📖

import {SimpleImageField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
    <SimpleImageField
      name="siffield"
    />
  )
}

[...]

export default HomePage

ImageField

The ImageField is a more powerful version of the SimpleImageField. In addition to giving the field a name you also have the oppertunity to pass the field an imageClassName as well as an imageStyle property to fulfill your styling requirements.

Wiki 📖

import {ImageField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
    <ImageField
      fieldOptions={{fieldName: "iffield"}}
      imageClassName="iffield"
      imageStyle={{width: '500px', height: '500px', objectFit: 'cover'}}
    />
  )
}

[...]

export default HomePage

SimplePdfField

SimplePdfFields as the name implies enables you to embed a PDF hosted on the ipfs.

Wiki 📖

import {SimplePdfField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
     <SimplePdfField name="spffield" pdfStyle={{height: 1000, width: 1000}} />
  )
}

[...]

export default HomePage

StreamField

Jaen StreamFields enable you to integrate editable blocks and to use as many of them as you like. In order to use this field you are required to build a block. You can find an example of a block below.

Wiki 📖

import {StreamField} from '@snek-at/jaen'
import {CardBlock} from '...'

const HomePage: ConnectedPageType = () => {
  return (
    <div style={{width: '50%', display: 'table'}}>
      <StreamField
        reverseOrder={false}
        name={'timeline'}
        blocks={[CardBlock]}
      />
    </div>
  )
}

[...]

export default HomePage

IndexField

If you want to link to childpages of a slug the IndexField is your friend. The fixedSlug property is not required. When none is provided the children of the current page are used if you like it is possible to specify the parentpage, the outerElement is the wrapper for all your items and the renderItem property allows you to build cards, teasers, buttons and more to your subpages.

Wiki 📖

import {IndexField} from '@snek-at/jaen'

const HomePage: ConnectedPageType = () => {
  return (
    <IndexField
      fixedSlug={'home'}
      outerElement={() => <div />}
      renderItem={(item, key, navigate) => (
        <p key={key}>
          Slug: {item.slug} Title: {item.title}{' '}
          <button onClick={() => navigate()}>Goto</button>
        </p>
       )}
    />
  )
}

[...]

export default HomePage

Blocks

The Block is the keystone of the StreamField. With the help of blocks you can build complex React-Components with editable content.

Wiki 📖

import {
  BC,
  prepareBlocks,
  ImageField,
  EditableField,
  RichTextField
} from '@snek-at/jaen'

type BlockType = {
  title: string
  extra: string
  text: string
  }

const Block: BC<BlockType> = ({
  fieldOptions,
  streamFieldWidth
}) => {
  const blocks = prepareBlocks<BlockType>(Block, fieldOptions)

  return (
    <>
      <div className="card">
        <h1>{title}</h1>
        {blocks['text']}
        {blocks['image']}
        {blocks['extra']}
      </div>
    </>
  )
}

Block.BlockType = 'Block'
Block.BlockFields = {
  image: ImageField,
  title: EditableField,
  extra: EditableField,
  text: RichTextField
}

export default Block
