gulp-ui5-preload

Creates a Component-preload.js or library-preload.json file for openui5 / sapui5 projects. Creating a preload file can speed up the initial load time of your webapp, by reducing the number of HTTP requests / roundtrips to load your code. The preload file can combine your js artifacts, xml, html and json views as well as .properties files into a single Component-preload.js / library-preload.json file.

Install

$ npm install --save-dev gulp-ui5-preload

Usage

Simple example.

var ui5preload = require('gulp-ui5-preload');

gulp.task('ui5preload', function(){
  return gulp.src([
					'src/ui/**/**.+(js|xml)',
					'!src/ui/thirdparty/**' //exclude files that don't belong in preload (optional)
                  ])
          .pipe(ui5preload({base:'src/ui',namespace:'my.project.ui'}))
          .pipe(gulp.dest('dist'));
     })

Example with uglify / minify js and xml.

// npm install --save-dev gulp-ui5-preload gulp-uglify gulp-pretty-data gulp-if
var ui5preload = require('gulp-ui5-preload');
var uglify = require('gulp-uglify');
var prettydata = require('gulp-pretty-data');
var gulpif = require('gulp-if');

gulp.task('ui5preload', function(){
  return gulp.src([
					'src/ui/**/**.+(js|xml)',
					'!src/ui/thirdparty/**'
                  ])
          .pipe(gulpif('**/*.js',uglify()))    //only pass .js files to uglify
          .pipe(gulpif('**/*.xml',prettydata({type:'minify'}))) // only pass .xml to prettydata 
          .pipe(ui5preload({base:'src/ui',namespace:'my.project.ui'}))
          .pipe(gulp.dest('dist'));
     })

API

ui5Preload(options) -> vinyl through-stream

Accepts an options object. Returns a vinyl through-stream which collects all .xml and .js files and emits a single vinyl file (Component-preload.js / library-preload.json) which is passed downstream.

options

base

• required
• Type: string

The base / entry path of your app. Usually the same location where your index.html and the Component.js resides. Can also be just './' to point to the root of your project.

namespace

• Type: string
• Default: ''
• Example: my.company.app

The namespace at the base path. All source files are treated as sub-namespaces of this namespace, relative to the base path.

fileName

• Type: string
• Default: 'Component-preload.js' or 'library-preload.json' (depends on isLibrary option)

File name of the combined file to emit.

isLibrary

• Type: boolean
• Default: false

If set to true a library-preload.json file is emitted instead of a Component-preload.js file (default). The emitted file contents between those options vary a little bit.
