@placeshaker/powerbi-visuals-webpack-plugin

This is a fork from powerbi-visuals-webpack-plugin done to resolve some issues related to webpack 5 and pluginTemplate functionality from the plugin and typescript.

This plugin allows developing custom visuals by using webpack to build a visual package.

Provides following functionality:

• Creates assets for developer server
• Creates *.pbiviz package.

How to use the plugin

Plugin options

Plugin config description

  var defaultOptions = {
      visual: {
        name: "Visual name",
        displayName: "Visual name for displaying in visuals panel",
        guid: `Unique GUID for the visual (generated by plugin)`,
        visualClassName: "Visual class name, it is used by visual plugin to create instance of the visual",
        version: "Visual version",
        description: "Visual description",
        supportUrl: "URL for support"
    },
    author: "Author of the visual",
    apiVersion: "API version",
    stringResourcesPath: [
      "Paths to localization files"
    ],
    capabilities: {
        // Visual capabilities
    },
    iconImage: "Icon file as base64 string",
    devMode: "development mode",
    packageOutPath: "location to create *.pbiviz file",
    cssStyles: "styles",
    generateResources: "it is used --resources flag in pbiviz tools",
    generatePbiviz: "it is used by --no-pbiviz flag in pbiviz tools"
  };

How to build a visual with webpack

1. Install all required libraries to build a visual

   npm i webpack webpack-cli powerbi-visuals-webpack-plugin mini-css-extract-plugin webpack-bundle-analyzer extra-watch-webpack-plugin ts-loader less-loader less babel-loader json-loader base64-inline-loader @babel/preset-env @babel/core css-loader webpack-dev-server --save-dev

2. Install babel JS compiler and polyfills

   npm i  @babel/runtime @babel/runtime-corejs3 core-js --save

3. Install powerbi-visuals-api package with required API version

   Run the following command to install the latest version of API package

   npm i powerbi-visuals-api --save

4. Create SSL certificates (optional)

   You need generate SSL certificates manually or copy files from powerbi-visuals-tools instance.

   Read more about certificates in documentation.

   Also, you can use certificates from powerbi-visuals-toos or use autogenerated certificates by webpack-dev-server. Just skip section 4 to use webpack-dev-server certificates.

   4.1 Run the following command:

       npm i powerbi-visuals-tools@beta --save-dev

   to install the latest version of tools

   4.2 create script command to generate certificate.

   Add into scripts section of package.json command "cert": "pbiviz --install-cert":

       ...
           "scripts": {
               "cert": "pbiviz --install-cert"
           },
       ...

   Execute command npm run cert. You should get message:

       error  Certificate not found. The new certificate will be generated
       info   Certificate generated. Location is <visual root>\node_modules\powerbi-visuals-tools\certs\PowerBICustomVisualTest_public.pfx. Passphrase is '<YOUR_PASSPHRASE>'

   Apply path node_modules\powerbi-visuals-tools\certs\PowerBICustomVisualTest_public.pfx in webpack.config.js at https section of devServer parameters:

   ...
       https: {
           pfx: fs.readFileSync(path.join(__dirname, `node_modules\powerbi-visuals-tools\certs\PowerBICustomVisualTest_public.pfx`)), // for windows
           passphrase: "<YOUR_PASSPHRASE>"
       },
   ...

5. Use sample of config webpack 4. (copy into webpack.config.js)

   const path = require('path');
   const fs = require("fs");
   
   // werbpack plugin
   const webpack = require("webpack");
   const PowerBICustomVisualsWebpackPlugin = require('powerbi-visuals-webpack-plugin');
   const MiniCssExtractPlugin = require("mini-css-extract-plugin");
   const Visualizer = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
   const ExtraWatchWebpackPlugin = require('extra-watch-webpack-plugin');
   
   // api configuration
   const powerbiApi = require("powerbi-visuals-api");
   
   // visual configuration json path
   const pbivizPath = "./pbiviz.json";
   const pbivizFile = require(path.join(__dirname, pbivizPath));
   
   // the visual capabilities content
   const capabilitiesPath = "./capabilities.json";
   const capabilitiesFile = require(path.join(__dirname, capabilitiesPath));
   
   const pluginLocation = './.tmp/precompile/visualPlugin.ts'; // path to visual plugin file, the file generates by the plugin
   
   // string resources
   const resourcesFolder = path.join(".","stringResources");
   const localizationFolders = fs.existsSync(resourcesFolder) && fs.readdirSync(resourcesFolder);
   const  statsLocation = "../../webpack.statistics.html";
   
   // babel options to support IE11
   let babelOptions = {
       "presets": [
           [
               require.resolve('@babel/preset-env'),

           	powerbi: 'corePowerbiObject'
       	})
       ]
   };

6. Add new script to build a visual package

   Add new command "package": "webpack" into scripts section of package.json:

   "scripts": {
       "cert": "pbiviz --install-cert",
       "package": "webpack"
   }

   Run npm run package command to create visual package.

Add webpack-dev-server package to debug custom visual

Install webpack-dev-server:

npm i webpack-dev-server --save-dev

Add command "start": "webpack-dev-server" into scripts section of package.json :

"scripts": {
    "cert": "pbiviz --install-cert",
    "package": "webpack",
    "start": "webpack-dev-server"
}

Run command npm run start to start dev server.
