pv-scripts

CLI for zero configuration frontend-toolchain setup.

Installation

npm i @pro-vision/pv-scripts -D

Usage

Requirements

To use the CLI, you need to create at least the two entry-files (jsEntry, jsLegacyEntry), see Basic Configuration.

Command Line Interface

Installing this package gives you the CLI pv-scripts. It can be used with the parameters dev and prod.

To run a locally installed version of the pv-scripts, you can either call the pv-scripts command directly from your local node_modules/.bin folder or by using npx.

dev: Transpiles and bundles your code (JS/TS/JSX/TSX/SCSS) via webpack (+ all needed loaders) and opens a webpack-dev-server on the configured port (default: 8616).

npx pv-scripts dev

prod: Transpiles and bundles your code (JS/TS/JSX/TSX/SCSS) via webpack (+ all needed loaders) and writes them to your target folder.

npx pv-scripts prod

CLI flags

--stats or --statsJson

Webpack build will use webpack-bundle-analyzer to generate an html report or json output regarding the bundle sizes and its composition. Which will be stored under target/report_module.html | target/report_legacy.html and target/report_module.json | target/report_legacy.json.

This flag should only be used in combination with prod build to have a realistic information from the optimized bundles.

Configuration

Basic Configuration

Basic Configuration can be done in a pv.config.js file in the npm project root-folder. Possible configuration values are:

key type default usage
devServerPort number 8616 set webpack-dev-server port
srcPath string "src" defines the working directory
destPath string "target" defines where to put bundled files
namespace string "" this controls the name-prefix on your bundled files following this pattern [namespace].app.[?legacy].(js|css)
jsEntry string "src/index.ts" defines path of your (JS|TS|JSX|TSX) entry file
jsLegacyEntry string "src/legacyIndex.ts" defines path of your (JS|TS|JSX|TSX) legacy entry file
disableLegacyBuild boolean false disables legacy build
cssEntry string "src/index.scss" defines path of your SCSS entry file. If src/index.scss does not exist, no error is thrown but the css generation is simply skipped
useTS boolean true defines whether you want to use Typescript
useReact boolean false defines whether you want to use React
hbsEntry string defines path of your handlebars entry file
hbsTarget string defines path to your handlebars target file
handlebarsLoaderOptions string {} Object with additional options for the handlebars-loader. See https://github.com/pcardune/handlebars-loader for these options. Paths are relative to pv.config.js
copyStaticFiles boolean false defines whether content of /static should be copied to target
cleanDest boolean false defines whether the destination folder should be cleaned before every pv-scripts run
fontsSrc string "resources/fonts/" defines folder in which the fonts are located
resourcesSrc string "resources" defines resources folder which is copied to target/resources
autoConsoleClear boolean "false" defines whether the console should be cleared automatically in dev-mode
Example:
// pv.config.js
module.exports = {
  devServerPort: 8616,
  destPath: "target",
  jsEntry: "src/index.js",
  jsLegacyEntry: "src/legacyIndex.js",
  cssEntry: "src/index.scss",
  useTS: false,
  useReact: false,
  copyStaticFiles: false
};

Further Configurations

For further customization of the webpack-config, specific config-files can be added to the npm project root-folder.

webpack.config.js: Valid webpack.config file which will be merged with both (dev/prod) default configs.

webpack.config.module.js: Valid webpack.config file which will be merged with the module build of both (dev/prod) default configs.

webpack.config.legacy.js: Valid webpack.config file which will be merged with the legacy build of both (dev/prod) default configs.

webpack.config.dev.js: Valid webpack.config file which will be merged with the dev default config.

webpack.config.dev.module.js: Valid webpack.config file which will be merged with the module build of the dev default config.

webpack.config.dev.legacy.js: Valid webpack.config file which will be merged with the legacy build of the dev default config.

webpack.config.prod.js: Valid webpack.config file which will be merged with the prod default config.

webpack.config.prod.module.js: Valid webpack.config file which will be merged with the module build of the prod default config.

webpack.config.prod.legacy.js: Valid webpack.config file which will be merged with the legacy build of the prod default config.

Browserslist

A default browser query is used for compiling javascript and css. i.e. IE11 for the "legacy" bundle and latest 2 versions of evergreen browsers (chrome, firefox, safari, edge) for the "modern" bundle. And all combined for the css output. You can define your own browserslist to override any of these target groups. Don't forget to define default browsers, browser for [modern] or [legacy] environment. See default .browserslistrc file for an example.
