maptalks support ssr，but I don't run the examples

Nobody has claimed this yet.

const maptalks = require('maptalks');
//with node-canvas 2.0
const { createCanvas, Image } = require('canvas');

//load node adapters, source: https://github.com/maptalks/maptalks.node
require('maptalks.node');
//register node-canvas's Image as a global class
global.Image = Image;

const canvas = createCanvas(400, 300);
const map = new maptalks.Map(canvas, {
center : [0, 0],
zoom : 3,
baseLayer : new maptalks.TileLayer('base', {
'urlTemplate' : 'http://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png',
'subdomains' : ['a','b','c','d','e'],
})
});

Start by running the supplied Node.js snippet with maptalks, node-canvas 2.0, and maptalks.node, then identify where the SSR example stops working. Confirm the expected server-side rendering behavior and document or implement the missing support so the example runs successfully.
