@metablock/server v0.26.8

A dev server for metablock

This package allow to serve metablocks during development.

yarn add @metablock/server --dev

To enable SSR (server side rendering) via puppeteer you may need to

apt install libcairo2 libpango-1.0-0 libxkbcommon-x11-0 libgbm-dev libatk-bridge2.0-0 libcups2 libnss3

Use with webpack

To use it install this additional dev dependency

yarn add webpack-require-from --dev

and use it with webpack.config.js

import RequireFrom from "webpack-require-from";
import { devServer } from "@metablock/server";

const PWD = process.cwd();
const resolvePath = (relativePath) => path.resolve(PWD, relativePath);


const STATIC_PATH = "/dist/";

const webPackConfig = {
  devServer: devServer("https://myblock.mblock.me", {
    ssr: true,
    hot: true,
    ssrPlugins: [statusCode],
    static: {
      directory: resolvePath(`.${STATIC_PATH}`),
      publicPath: STATIC_PATH,
    },
  }),
  plugins: [
    new RequireFrom({
      variableName: "__bundle_url__",
    }),
  ],
};

The additional options for the server are

• ssr to enable server side rendering via puppeteer
• slowMo to slow down puppeteer operations by the specified amount of milliseconds (this will set headless option to false so you can see what the server side browser is doing). Only used when mode=development.
• docker to signal the server is running inside a docker container
• ssrPlugins additional plugins for customizing SSR

For example, using SSR in dev mode:

import { devServer, statusCode } from "@metablock/server";

const webPackConfig = {
  mode: "development",
  devServer: devServer("https://myblock.mblock.sh", {
    ssr: true,
    slowMo: 250,
    ssrPlugins: [statusCode],
    hot: true
  })
};
