mobiledoc-vdom-renderer

This package renders Mobiledoc documents through calls to a createElement function, often referred to as h (for hyperscript) or provided as a global if you are using JSX. This allows embedding Mobiledoc content “natively” as virtual DOM in frameworks like React, preact, or hyperapp.

Alternatively, you can skip the “virtual” step and build DOM directly with a micro-renderer such as ultradom or even convert mobiledocs to arbitrary ASTs by adopting createElement’s standard (type: (properties: object) => Node, properties: object, ...children: Node[]) => Node signature for your builder.

Installation

npm install mobiledoc-vdom-renderer --save

or

yarn add mobiledoc-vdom-renderer

Usage

/* @jsx h */
import Renderer from 'mobiledoc-vdom-renderer'

// render: (mobiledoc: Mobiledoc) => Node[]
const render = Renderer({ createElement: h })

// Instant <Mobiledoc/> Component
export default function Mobiledoc({ mobiledoc }) {
  return <div>{render(mobiledoc)}</div>
}

API

import Renderer, { upgradeMobiledoc } from 'mobiledoc-vdom-renderer'

Renderer (default export)

Renderer: (options: RendererOptions) => RenderFunction

Creates a render function ((mobiledoc: Mobiledoc) => Node[]) from the supplied options

• options required

  {
    createElement: CreateElement,
    getCardComponent?: ComponentGetter,
    getAtomComponent?: ComponentGetter,
    getMarkupComponent?: ComponentGetter = getMarkupComponentDefault
  }

  • createElement required

    createElement: (
      type: string | Component,
      properties?: object,
      ...children: Node[]
    ) => Node

    Any compatible function such as React.createElement or hyperscript h

  • getCardComponent

    getCardComponent: (type: string) => string | Component

    Function which returns a string (tag name) or component ((properties: { payload: object }) => Node) for the given card type (required if rendering a mobiledoc with cards)

  • getAtomComponent

    getAtomComponent: (type: string) => string | Component

    Function which returns a string (tag name) or component ((properties: { payload: object }) => Node) for the given atom type (required if rendering a mobiledoc with atoms)

  • getMarkupComponent

    getMarkupComponent: (tagName: string) => string | Component = getMarkupComponentDefault

    Function which returns a string (tag name) or component ((attributes: object) => Node) to override rendering for the given tag name (for instance, to mix in HTML attributes or render a custom component instead)

    import { getMarkupComponentDefault } from 'mobiledoc-vdom-renderer'

    getMarkupComponent’s default behavior is exported as getMarkupComponentDefault, which passes through valid tag names but throws an error for tags not on Mobiledoc’s markup section or markup whitelists; passing through all tag names instead (as in tagName => tagName) allows (non-standard) mobiledocs containing arbitrary tags to be rendered

upgradeMobiledoc

upgradeMobiledoc: (mobiledoc: Mobiledoc | Mobiledoc02x) => Mobiledoc

Upgrades a mobiledoc from any released version to the latest specification (0.3.1)

Type definitions

import { Mobiledoc, MobiledocTypes } from 'mobiledoc-vdom-renderer'

This package includes complete Typescript definitions describing the Mobiledoc format, which may be imported directly for use with any mobiledoc-related code.

Contributing

Contributions—including pull requests, bug reports, documentation, and suggestions—are welcome!

The code is written in Typescript in a pure functional style. Opinionated “best practices,” including functional programming, are strictly enforced by linters—it’ll help to use a code editor which supports both as-you-type linting and type-checking.

Test-driven development

• Installation

git clone https://github.com/bustle/mobiledoc-vdom-renderer.git
cd mobiledoc-vdom-renderer/
npm install

• npm start

  Watches the filesystem for changes (chokidar-cli) then lints (Typescript, Standard style, functional JS practices) and tests (ava snapshots) each file you touch

• Other useful commands

  • npm test

    Run the linters and all tests and generate a coverage report (nyc)

  • npm run snapshot

    Updates all snapshots; check your git diff before committing!

  • npm run format

    Fixes many linting errors and applies prettier whitespace conventions
