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 build a visual with webpack
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 json-loader less-loader less css-loader webpack-dev-server --save-devInstall optional libraries to build JSX files
If you aren't going to build JSX files, then you can skip this step and delete all babel in section 5.
npm i @babel/preset-react @babel/runtime @babel/runtime-corejs3 @babel/core @babel/preset-env babel-loader --save-devInstall the latest version of API package
npm i powerbi-visuals-api --saveCreate 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-toolsor use autogenerated certificates bywebpack-dev-server. Just skip section 4 to use webpack-dev-server certificates.4.1 Run the following command:
npm i powerbi-visuals-tools@latest --save-devto install the latest version of tools
4.2 create script command to generate certificate.
Add into
scriptssection ofpackage.jsoncommand"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

Add new command
"package": "webpack"intoscriptssection ofpackage.json:"scripts": { "cert": "pbiviz --install-cert", "package": "webpack" }Run
npm run packagecommand to create visual package.
Add webpack-dev-server package to debug custom visual
Install webpack-dev-server:
npm i webpack-dev-server --save-devAdd command "start": "webpack serve" into scripts section of package.json :
"scripts": {
"cert": "pbiviz --install-cert",
"package": "webpack",
"start": "webpack serve"
}Run command npm run start to start dev server.
