An UNOFFICIAL Babel transform plugin for SAP UI5 modules. It transforms SAP UI5 module imports into sap.ui.define() format, while skips transformation for the other imports. The other imports should be handled by the packaging tool like webpack.
- Class, inheritance and
superkeyword - UI5's
metadatafield - Static methods and fields
Currently this version only supports Babel 6.
Suppose that in your project, all the source codes are stored in app folder.
<your-ui5-project> ├── <app> │ └── <your_module> │ └── <sub_folder> │ ├── ClassA.js │ └── ClassB.js ├── .babelrc ├── webpack.config.js └── package.json { ... "devDependencies": { "babel-core": "^6.25.0", "babel-loader": "^7.1.1", "babel-plugin-syntax-class-properties": "^6.13.0", "babel-plugin-transform-ui5": "^6.1.2", "babel-polyfill": "^6.23.0", "babel-preset-env": "^1.6.0", "webpack": "^3.4.1" } ... }$ npm install --save-dev babel-preset-transform-ui5 babel-plugin-syntax-class-properties Add transform-ui5 to the plugins and pass the options to track the imports that should be transformed.
{ "sourceRoot": "./", "presets": [ [ "env", { "loose": true, "modules": false } ] ], "plugins": [ "syntax-class-properties", ["transform-ui5", { "libs": ["^sap", "^jquery"], "files": ["app/controller", "app/model"] }] ] } The
sourceRootproperty can helps the plugin to output the right namespace.
Add a gulpfile.js in your project root folder.
module.exports = { entry: { 'Component': ['babel-polyfill', path.resolve(__dirname, 'app/Component.mjs')], 'test/unit/allTests': ['babel-polyfill', path.resolve(__dirname, 'app/test/unit/allTests.mjs')] }, output: { path: path.resolve(__dirname, 'app/'), filename: '[name].js' }, // devtool: 'cheap-module-eval-source-map', module: { rules: [ { test: /\.m?js$/, exclude: /node_modules/, loaders: [ 'babel-loader' ] } ] } };Please take a look at example, you'll find the answer.
