mithril-node-render

Use mithril views to render server side

Demo

Installation

npm install mithril-node-render

Usage

// Make Mithril happy
if (!global.window) {
  global.window = global.document = global.requestAnimationFrame = undefined
}
var m = require('mithril')
var render = require('mithril-node-render')
render(m('span', 'huhu')).then(function (html) {
  // html === '<span>huhu</span>'
})
var html = render.sync(m('span', 'huhu'))
// html === '<span>huhu</span>'

Async components

As you see the rendering is asynchronous. It lets you await certain data from within oninit hooks.

var myAsyncComponent = {
  oninit: function (node, waitFor) {
    waitFor(new Promise(function (resolve) {
      node.state.foo = 'bar'
      resolve()
    }))
  },
  view: function (node) {
    return m('div', node.state.foo)
  }
}
render(myAsyncComponent).then(function (html) {
  // html === '<div>bar</div>'
})

Sync rendering

You can also render synchronously. You just don’t get the waitFor callback.

var myAsyncComponent = {
  oninit: function (node, waitFor) {
    // waitFor === undefined
    new Promise(function (resolve) {
      node.state.foo = 'bar'
      resolve()
    })
  },
  view: function (node) {
    return m('div', node.state.foo)
  }
}
var html = render.sync(myAsyncComponent)
// html === '<div>bar</div>'

Options

Optionally pass in options as an object: render(component, options).

The following options are supported:

escapeAttribute(value)
Default: render.escapeAttribute
A filter function for attribute values. Receives value, returns what is printed.

escapeText(value)
Default: render.escapeText
A filter function for string nodes. Receives value, returns what is printed.

strict
Default: false
Set this to true to close all empty tags automatically. Default is standard HTML mode where tags like <br> and <meta> are allowed to implicitly close themselves. This should be set to true if you’re rendering XML-compatible HTML documents.

xml
Default: false
Set this to true to render as generic XML instead of (possibly XML-compatible) HTML. Default is HTML mode, where children of void elements are ignored. This implies strict: true.
