ui5-task-transpile-gen

A UI5 builder task that transpiles ES6 to ES5, including async/await, with Babel at build time, registered in ui5.yaml with a bundle definition that includes the regenerator runtime.

An app written with ES6 classes or async/await has to reach browsers that run ES5. This task for ui5-builder transpiles the sources at build time. It is registered under builder/customTasks in ui5.yaml with afterTask: replaceVersion, together with a bundle definition: regenerator-runtime/runtime.js in raw mode, the app's manifest, controllers, views, models and i18n files in preload mode, and the bundle options optimize and usePredefineCalls. The package is a development dependency that must also be listed under ui5 > dependencies in package.json. The registry record lists Babel's preset-env and regenerator-runtime among its dependencies.

ui5-task-transpile-gen

UI5tooling task for transpiling ES6 to ES5 including Async Await

Task for ui5-builder, enabling ES6 support.

Install

npm install ui5-task-transpile-gen --save-dev

Usage

  1. Define the dependency in $yourapp/package.json:
"devDependencies": {
    // ...
    "ui5-task-transpile-gen": "*"
    // ...
},
"ui5": {
  "dependencies": [
    // ...
    "ui5-task-transpile-gen",
    // ...
  ]
}

As the devDependencies are not recognized by the UI5 tooling, they need to be listed in the ui5 > dependencies array. In addition, once using the ui5 > dependencies array you need to list all UI5 tooling relevant dependencies.

  1. configure it in $yourapp/ui5.yaml:
builder:
  customTasks:
  - name: ui5-task-transpile-gen
    afterTask: replaceVersion
  bundles:
  - bundleDefinition:
      name: namespace/appname/Component-preload.js
      defaultFileTypes:
      - ".js"
      - ".json"
      - ".xml"
      - ".html"
      - ".library"
      sections:
      - mode: raw
        filters:
        - namespace/appname/regenerator-runtime/runtime.js
      - mode: preload
