h-Ionic-cli

Helper scripts to get Ionic apps up and running quickly (minus the config overload).

To get the latest h-ionic-cli, please run:

cnpm install h-ionic-cli@latest --save-dev

Config Defaults

Out of the box, Ionic starters have been preconfigured with great defaults for building fast apps, including:

  • Multi-core processing tasks in parallel for faster builds
  • In-memory file transpiling and bundling
  • Transpiling source code to ES5 JavaScript
  • Ahead of Time (AoT) template compiling
  • Just in Time (JiT) template compiling
  • Template inlining for JiT builds
  • Bundling modules for faster runtime execution
  • Treeshaking unused components and dead-code removal
  • Generating CSS from bundled component Sass files
  • Autoprefixing vendor CSS prefixes
  • Minifying JavaScript files
  • Compressing CSS files
  • Copying src static assets to www
  • Linting source files
  • Watching source files for live-reloading

Just the bullet list above is a little overwhelming, and each task requires quite a bit of development time just to get started. Ionic App Script's intention is to make it easier to complete common tasks so developers can focus on building their app, rather than building build scripts.

Note that the Ionic Framework's source is made up of modules and can be packaged by any bundler or build process. However, this project's goal is provide simple scripts to make building Ionic apps easier, while also allowing developers to further configure their build process.

To run the build script found in the package.json scripts property, execute:

npm run build

Custom Configuration

In many cases, the defaults which Ionic provides cover most of the scenarios required by developers; however, Ionic App Scripts does provide multiple ways to configure and override the defaults for each of the various tasks. Note that Ionic will always apply its defaults for any property that was not provided by custom configuration.

Default Config Files

package.json Config

Ionic projects use the package.json file for configuration. There's a handy config property which can be used. Below is an example of setting a custom config file using the config property in a project's package.json.

  "config": {
    "ionic_cleancss": "./config/cleancss.config.js"
  },

Command-line Flags

Remember how we're actually running ionic-app-scripts from the scripts property of a project's package.json file? Well we can also add command-line flags to each script, or make new scripts with these custom flags. For example:

  "scripts": {
    "build": "ionic-app-scripts build --webpack ./config/webpack.dev.config.js",
    "minify": "ionic-app-scripts minify --cleancss ./config/cleancss.config.js",
  },

The same command-line flags can be also applied to npm run commands too, such as:

npm run build --webpack ./config/webpack.dev.config.js

Ionic Environment Variables

These environment variables are automatically set to Node's process.env property. These variables can be useful from within custom configuration files, such as custom webpack.config.js file.

Environment VariableDescription
IONIC_ENVValue can be either prod or dev.
IONIC_ROOT_DIRThe absolute path to the project's root directory.
IONIC_SRC_DIRThe absolute path to the app's source directory.
IONIC_WWW_DIRThe absolute path to the app's public distribution directory.
IONIC_BUILD_DIRThe absolute path to the app's bundled js and css files.
IONIC_TMP_DIRTemp directory for debugging generated/optimized code and various build tasks
IONIC_NODE_MODULES_DIRThe absolute path to the node_modules directory.
IONIC_ANGULAR_DIRThe absolute path to the ionic-angular node_module directory.
IONIC_APP_SCRIPTS_DIRThe absolute path to the h-ionic-cli node_module directory.
IONIC_SOURCE_MAP_TYPEThe Webpack devtool setting. eval and source-map are supported.
IONIC_GENERATE_SOURCE_MAPDetermines whether to generate a sourcemap or not.
IONIC_TS_CONFIGThe absolute path to the project's tsconfig.json file
IONIC_APP_ENTRY_POINTThe absolute path to the project's main.ts entry point file
IONIC_APP_NG_MODULE_PATHThe absolute path to app's primary NgModule
IONIC_APP_NG_MODULE_CLASSThe exported class name for app's primary NgModule
IONIC_GLOB_UTILThe path to Ionic's glob-util script. Used within configs.
IONIC_CLEAN_BEFORE_COPYAttempt to clean existing directories before copying files.
IONIC_CLOSURE_JARThe absolute path ot the closure compiler jar file
IONIC_OUTPUT_JS_FILE_NAMEThe file name of the generated javascript file
IONIC_OUTPUT_CSS_FILE_NAMEThe file name of the generated css file
IONIC_WEBPACK_FACTORYThe absolute path to Ionic's webpack-factory script
IONIC_WEBPACK_LOADERThe absolute path to Ionic's custom webpack loader
IONIC_BAIL_ON_LINT_ERRORBoolean determining whether to exit with a non-zero status code on error
IONIC_TYPE_CHECK_ON_LINTBoolean determining whether to type check code during lint or not
IONIC_AOT_WRITE_TO_DISK--aotWriteToDisknullSet to true to write files to disk for debugging
IONIC_PRINT_WEBPACK_DEPENDENCY_TREEboolean to print out a dependency tree after running Webpack
IONIC_PARSE_DEEPLINKSboolean to enable parsing the Ionic 3.x deep links API for lazy loading
IONIC_BUILD_TO_ES5boolean to enable converting bundle to ES5 for production deployments
IONIC_START_WATCH_TIMEOUTMilliseconds controlling the default watch timeout

The process.env.IONIC_ENV environment variable can be used to test whether it is a prod or dev build, which automatically gets set by any command. By default the build and serve tasks produce dev builds (a build that does not include Ahead of Time (AoT) compilation or minification). To force a prod build you should use the --prod command line flag.

process.env.IONIC_ENV environment variable is set to prod for --prod builds, otherwise dev for all other builds.

All Available Tasks

These tasks are available within ionic-app-scripts and can be added to npm scripts or any Node command.

TaskDescription
buildA complete build of the application. It uses development settings by default. Use --prod to create an optimized build
cleanEmpty the www/build directory.
cleancssCompress the output CSS with CleanCss
copyRun the copy tasks, which by defaults copies the src/assets/ and src/index.html files to www.
lintRun the linter against the source .ts files, using the tslint.json config file at the root.
minifyMinifies the output JS bundle and compresses the compiled CSS.
sassSass compilation of used modules. Bundling must have at least ran once before Sass compilation.
watchRuns watch for dev builds.

Example NPM Script:

  "scripts": {
    "minify": "ionic-app-scripts minify"
  },

Tips

  1. The Webpack devtool setting is driven by the ionic_source_map_type variable. It defaults to source-map for the best quality source map. Developers can enable significantly faster builds by setting ionic_source_map_type to eval.
  2. By default, the lint command does not exit with a non-zero status code on error. To enable this, pass --bailOnLintError true to the command.
"scripts" : {
  ...
  "lint": "ionic-app-scripts lint"
  ...
}
npm run lint --bailOnLintError true
