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.
$ npm install --save-dev gulp-ui5-preload
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'));
})
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.
- 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.
- 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.
- Type:
string
- Default: 'Component-preload.js' or 'library-preload.js' (depends on
isLibrary
option)
File name of the combined file to emit.
- Type:
boolean
- Default: false
If set to true
a library-preload.js
file is emitted instead of a Component-preload.js
file (default). The emitted file contents between those options vary a little bit.
- Type:
string
- Default: 'js'
The output format. Can be set to 'json' in order to emit a library-preload.json
file (which is required for UI5 versions < 1.40).
