Installation

This is how to use the plugin in your Silex instance or JS project

Add as a dependency

$ npm i --save @silexlabs/silex-cms

Add to Silex client config:

// silex-client.js
import Eleventy from './js/silex-cms/client.js'

export default function(config, options) {
  config.addPlugin(Eleventy, {
    dataSources: [{
      id: 'countries',
      type: 'graphql',
      name: 'Countries',
      url: 'https://countries.trevorblades.com/graphql',
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
    }],
    // ... Other options for @silexlabs/grapesjs-data-source plugin - see https://github.com/silexlabs/grapesjs-data-source
    dir: {
      input: 'pages/',
      css: 'css',
    },
    // ... Other options for @silexlabs/silex-cms plugin - see below
  })
}

And expose the plugin to the front end:

// silex-server.js
const StaticPlugin = require('@silexlabs/silex/dist/plugins/server/plugins/server/StaticPlugin').default
const node_modules = require('node_modules-path')
console.log('node_modules', node_modules('@silexlabs/silex-cms'))
module.exports = function(config, options) {
  config.addPlugin(StaticPlugin, {
    routes: [
      {
        route: '/js/silex-cms/',
        path: node_modules('@silexlabs/silex-cms') + '/@silexlabs/silex-cms/dist/',
      },
    ],
  })
}

Then start Silex with

npx @silexlabs/silex --client-config=silex-client.js --server-config=`pwd`/silex-server.js

11ty configuration

Install required 11ty packages:

$ npm install  @11ty/eleventy @11ty/eleventy-fetch @11ty/eleventy-img

You need to add a .eleventy.js file to your project, with the following content:

const { EleventyI18nPlugin } = require("@11ty/eleventy");
const Image = require("@11ty/eleventy-img");
  
module.exports = function(eleventyConfig) {
  // Serve CSS along with the site
  eleventyConfig.addPassthroughCopy({"silex/hosting/css/*.css": "css"});

  // For the fetch plugin
  eleventyConfig.watchIgnores.add('**/.cache/**')

  // i18n plugin
  eleventyConfig.addPlugin(EleventyI18nPlugin, {
    // any valid BCP 47-compatible language tag is supported
    defaultLanguage: "en", 
  });

  // Image plugin
  eleventyConfig.addShortcode("image", async function(src, alt, sizes) {
    let metadata = await Image(src, {
      widths: [300, 600],
      formats: ["avif", "jpeg"]
    });
    let imageAttributes = {
      alt,
      sizes,
      loading: "lazy",
      decoding: "async",
    };

    // You bet we throw an error on a missing alt (alt="" works okay)
    return Image.generateHTML(metadata, imageAttributes);
  });
};

Dev notes

Hidden states

• States with hidden property set to true
• Not rendered in the HTML page as liquid
• Not visible in the properties panel
• Visible in completion of expressions

Public states

• In the UI they are represented by a list in the properties panel "states" section
• In the HTML page they are rendered as "assign" liquid blocks before the element
• You get these states with getState(id, true)
• They are typically properties custom states the user need to create expressions, e.g. to use in the append filter

Private states

• In the UI they are represented in the properties panel as element's properties
• In the HTML page they are rendered as liquid blocks in place of the element, for loops, echo, if, etc.
• You get these states with getState(id, false)
• They are typically properties of the element, like "innerHTML", "src", "href", etc.
