How can I optimize this custom dojo 1.7.2 build - dojo

I am working on my first project which uses a dojo 1.7.2 component, and only need a vertical slider widget. I was able to create a custom build which is supposed to include only the modules needed for my stated dependencies. Using the following build profile, and the command C:\dojo-release-1.7.2-src\util\buildscripts>build -p profiles/km.admin.dashboard.profile.js -r the resulting release/dojo/dojo.js.uncompressed.js is 796kb, and the release/dojo/dojo.js is 236kb. Is there any way to exclude more unneeded modules to reduce the file size? For instance, I just opened the release/dojo/dojo.js.uncompressed.js and took a quick look, there is a dojo/json package, I am not using any json. How do I exclude it? Thank you.
dependencies = {
layers: [
{
name: 'dojo.js',
customBase: true,
dependencies: [
'dojo/dojo',
'dojo.aspect',
'dojo/selector/acme',
'dojo/cldr/nls/number',
'dijit.form.VerticalSlider',
'dijit.form.VerticalRule',
'dijit.form.VerticalRuleLabels'
]
}
],
staticHasFeatures: {
'dojo-trace-api':0,
'dojo-log-api':0,
'dojo-publish-privates':0,
'dojo-sync-loader':0,
'dojo-xhr-factory':0,
'dojo-test-sniff':0
},
prefixes: [
[ 'dijit', '../dijit' ],
[ 'dojox', '../dojox' ]
]
}

There are some approaches by which you can trim down dojo.js to a bare minimum and keep adding the modules within dojo.js that you really need.
See:
http://dojotoolkit.org/reference-guide/1.7/build/customBase.html
and also:
http://www.sitepen.com/blog/2008/07/01/dojo-in-6k/ (this is somewhat old and cutombase approach in the first link might work better)

Unable to use Aurelia plugin

I'm trying to move one of my custom elements into a plug-in so that I can re-use it across projects.
I had a look at the skeleton plugin and noticed that it has a src/index.js that returns a config with all custom elements defined as globalResources.
So I tried the same thing and I basically have:
src/index.js
export function configure (config) {
config.globalResources([
'./google-map',
'./google-map-location-picker',
'./google-map-autocomplete'
]);
}
And then I have each one of my custom elements next to index.js, for example:
google-map.js
import {inject, bindable, bindingMode, inlineView} from 'aurelia-framework';
#inlineView(`
<template>
<div class="google-map"></div>
</template>
`)
#inject(Element)
export class GoogleMapCustomElement {
// All the Custom Element code here
}
I've also set up a basic npm script that runs babel on the code and sticks it in dist/:
"main": "dist/index.js",
"babel": {
"sourceMap": true,
"moduleIds": false,
"comments": false,
"compact": false,
"code": true,
"presets": [ "es2015-loose", "stage-1"],
"plugins": [
"syntax-flow",
"transform-decorators-legacy",
"transform-flow-strip-types"
]
},
"scripts": {
"build": "babel src -d dist"
},
Tbh I'm not entirely sure this is all correct but I took some of it from the skeleton plugin and it seems to run fine.
Anyway, the problem I'm having is that after I install the plugin (npm install --save-dev powerbuoy/AureliaGoogleMaps), add it to my aurelia.json in build.bundles[vendor-bundle.js].dependencies and tell aurelia to use it in main.js (.use.plugin('aurelia-google-maps')) I get:
GET http://localhost:9000/node_modules/aurelia-google-maps/dist/index/google-map.js (404)
So my question is, where does it get the dist/index/ part from?? I'm configuring my globalResources in index.js but nowhere does it say that I have an index folder.
What am I doing wrong?
Bonus question: What is the bare minimum required to transpile my ES6 plug-in code so that others can use it? Does my babel configuration look correct?
What about referencing your plugin within aurelia.json, like this:
{
"name": "aurelia-google-maps",
"path": "../node_modules/aurelia-google-maps/dist",
"main": "index"
}
I have absolutely no idea why, but in order to solve this problem I actually had to move my custom elements inside an index/ folder.
So now I have this:
- index.js
- index/
- custom-element-one.js
- custom-element-two.js
And my index.js still looks like this:
export function configure (config) {
config.globalResources([
'./custom-element-one',
'./custom-element-two'
]);
}
Where it gets index/ from I guess I will never know, but this works at least.
I did need the babel plug-in Marton mentioned too, but that alone did not solve the mystery of the made up path.
Edit: To elaborate a bit further, if I name my main entry point something other than index.js the folder too needs that name. For example, if I were to rename index.js main.js I would need to put my globalResources inside a folder called main/.
Update:
Edit: thanks for clarifying why you don't want to use the whole skeleton-plugin package.
Focusing on your original question: aurelia-cli uses RequireJS (AMD format) to load dependencies. Probably, your current output has a different format.
Add transform-es2015-modules-amd to babel.plugins to ensure AMD-style output, so it will be compatible with RequireJS and therefore with aurelia-cli.
"babel": {
"sourceMap": true,
"moduleIds": false,
"comments": false,
"compact": false,
"code": true,
"presets": [ "es2015-loose", "stage-1"],
"plugins": [
"syntax-flow",
"transform-decorators-legacy",
"transform-flow-strip-types",
"transform-es2015-modules-amd"
]
}
Original:
There are several blog post about plugin creation, I started with this: http://patrickwalters.net/making-out-first-plugin/ .
Of course, there have been many changes since then, but it's a useful piece of information and most of it still applies.
I'd recommend using plugin-skeleton as project structure. It provides you with a working set of gulp, babel, multiple output formats out-of-the-box.
With this approach, your plugin's availability wouldn't be limited to JSPM or CLI only but everyone would have the possibility to install it regardless of their build systems.
Migration is fairly easy in your case:
Download skeleton-plugin
Copy your classes + index.js into src/
npm install
...wait for it...
gulp build
check dist/ folder
most of your pain should now be gone :)
Here are some details based on my observations/experience.
1. Main index.js/plugin-name.js:
In general, a main/entry point is required, where the plugin's configure() method is placed. It serves as a starting point when using it within an Aurelia application. This file could have any name, usually it's index.js or plugin-name.js (e.g. aurelia-google-maps.js) to make it clear for other developers what should be included for bundling. Set that same entry point in package.json as well.
In addition to globalResources, you can implement a callback function to allow configuration overrides. That can be called in the application, which will use the plugin. Example solution
Plugin's index.js
export * from './some-element';
export function configure(config, callback) {
// default apiKey
let pluginConfig = Container.instance.get(CustomConfigClass);
pluginConfig.apiKey = '01010101';
// here comes an override
if (callback) {
callback(pluginConfig);
}
...
config.globalResources(
'./some-element'
);
}
Your app's main.js
export function configure(aurelia) {
aurelia.use
.standardConfiguration()
.developmentLogging()
.plugin('aurelia-google-maps', (pluginConfig) => {
// custom apiKey
pluginConfig.apiKey = '12345678';
});
aurelia.start().then(a => a.setRoot());
}
2. HTML and CSS resources:
If you have html only custom elements, you can make them available using globalResources.
Custom css styling is going to require a bit of additional configuration in bundling configuration (see below).
3. Using the plugin with aurelia-cli: Documentation
One of the first new features you'll see soon is a command to help you with 3rd party module configuration. The command will inspect a previously npm-installed package, and make a configuration recommendation to you, automating the process if you desire.
While we are looking forward to that above moment, let's edit aurelia.json:
Configure plugin dependencies. If there are any external libraries (e.g. Bootstrap), then those should be included before your plugin.
Include your plugin:
...
{
"name": "plugin-name",
"path": "../node_modules/plugin-name/dist/amd",
"main": "plugin-name",
"resources": ["**/*.html", "**/*.css"] // if there is any
},
...
Now, your plugin is ready to include it in main.js as showed in Section 1..
I hope you didn't get sick of reading the word 'plugin' so many (21!) times. :D

Wallaby with Browserify and TypeScript modules

I am trying to get Wallaby to work with a TypeScript app, using Browserify and Wallabify. However, when I run Wallaby, it outputs No failing tests, 0 passing, and all test indicators are grey.
The file app/spec.setup.ts is responsible for loading node modules dependencies such as chai, sinon, and the app's main module. app/spec.util.ts provides some helpers, imported by individual spec files.
module.exports = function() {
var wallabify = require('wallabify');
var wallabyPostprocessor = wallabify({
entryPatterns: [
'app/spec.setup.ts',
'app/src/**/*.spec.ts'
]
}
);
return {
files: [
{pattern: 'app/spec.setup.ts', load: false, instrument: false},
{pattern: 'app/spec.util.ts', load: false, instrument: false},
{pattern: 'app/src/**/*.ts', load: false},
{pattern: 'app/src/**/*.spec.ts', ignore: true}
],
tests: [
{pattern: 'app/src/**/*.spec.ts', load: false}
],
testFramework: 'mocha',
postprocessor: wallabyPostprocessor,
bootstrap: function (w) {
// outputs test file names, with .ts extensions changed to .js
console.log(w.tests);
window.__moduleBundler.loadTests();
}
};
};
What's interesting is that I don't get any feedback from changing entryPatterns, even setting it to an empty array or invalid file names. The result is still the same. Only if I remove it entirely, I get errors such as Can't find variable: sinon.
I've also figured that the entryPatterns list may need the compiled file names, i.e. .js instead of .ts extension. However, when I do that, I get Postprocessor run failure: 'import' and 'export' may appear only with 'sourceType: module' on spec.setup.ts.
I don't know what is the correct way to configure Wallabify for TypeScript compilation, and I couldn't find any complete examples on the web, so I'd appreciate any hints.
P.S. with my current StackOverflow reputation I couldn't add two new tags: wallaby and wallabify. Could someone do me a favour and add the two tags please.
Because TypeScript compiler renames files to .js and applied before wallabify, you need to change your entry patterns like this to make it work:
entryPatterns: [
'app/spec.setup.js',
'app/src/**/*.spec.js'
]

Durandal.js optimizer not working (empty main-built.js)

I'm trying to get Durandal.js optimizer working on my test project, but it seems to generate nothing to main-built.js. I use the following command from node.js command prompt, in durandal/amd folder:

Tracing dependencies for: durandal/amd/almond-custom
Then, when I check main-built.js, it is empty. Can anyone help me what is the problem? I have several AMD modules in the test project, including Raphael.js AMD modules.
My requirejs configuration looks like this:
requirejs.config({
paths: {
'text': 'durandal/amd/text',
'eve': './raphael-amd/eve.0.3.4',
'raphael.core': './raphael-amd/raphael.2.1.0.core',
'raphael.svg': './raphael-amd/raphael.2.1.0.svg',
'raphael.vml': './raphael-amd/raphael.2.1.0.vml',
'raphael': './raphael-amd/raphael.2.1.0.amd',
'tinymce': "../Scripts/tinymce/jquery.tinymce.min"
}
});
In the same amd folder, where optimizer is stored, try running node r.js -o app.build.js. I've seen r.js sometimes choke about some dependencies, which resolves without problem when loading via require.js. For whatever reason the error messages won't show up when using optimizer --verbose. Typically the error message provides enough information to see where this occurs and if you've to update require.contig.paths or a specific define dependency.

Create different versions form one bootstrap file with require.js

I develop an iPad/iPhone App web app. Both share some of the resources. Now I wanna build a bootstrap js that looks like this:
requirejs(['app'], function(app) {
app.start();
});
The app resource should be ipadApp.js or iphoneApp.js. So I create the following build file for the optimizer:
{
"appDir": "../develop",
"baseUrl": "./javascripts",
"dir": "../public",
"modules": [
{
"name": "bootstrap",
"out": "bootstrap-ipad.js",
"override": {
"paths": {
"app": "ipadApp"
}
}
},
{
"name": "bootstrap",
"out": "bootstrap-iphone.js",
"override": {
"paths": {
"app": "iphoneApp"
}
}
}
]
}
But this doesn't seems to work. It works with just one module but not with the same module with different outputs.
The only other solution that came in my mind was 4 build files which seems a bit odd. So is there a solution where i only need one build file?
AFAIK the r.js optimizer can only output a module with a given name once - in your case you are attempting to generate the module named bootstrap twice. The author of require.js, #jrburke made the following comment on a related issue here:
...right now you would need to generate a separate build command for each script being targeted, since the name property would always be "almond.js" for each one.
He also suggests:
...if you wanted just one build file to run, you could create a node program and drive the optimizer multiple times in one script file. This example shows using requirejs as a module and calling requirejs.optimize().
I took a similar approach in one of my projects - I made my build.js file an ERB template and created a Thor task that ran through my modules and ran r.js once for each one. But #jrburke's solution using node.js is cleaner.

Make a build in dojo 1.7.2

Well, I read all about build and all about dojo. Three days nightmare and so on... Need some help.
I'm using the last version of dojo. 1.7.2 in:
</sites/somesite/scripts/dojo17>
which contains
--dojo
--dijit
--dojox
--utils
I use the following profile:
dependencies = {
stripConsole: "all",
action: "release",
optimize: "shrinksafe",
layerOptimize: "shrinksafe",
//optimize: "closure",
//layerOptimize: "closure",
//mini: true,
//localeList : 'en-us',
//cssOptimize: "comments",
//selectorEngine: "acme",
releaseName: "content7",
layers: [
{
// This is a specially named layer, literally 'dojo.js'
// adding dependencies to this layer will include the modules
// in addition to the standard dojo.js base APIs.
name: "dojo.js",
customBase : true,
dependencies: [
"dojo.fx",
"dijit.form.Button",
"dojox.gauges.AnalogGauge",
"dojox.gauges.AnalogArcIndicator",
"dojox.gauges.AnalogNeedleIndicator",
"myApp.smartmix"
]
}
],
prefixes: [
[ "dijit", "../dijit" ],
[ "dojox", "../dojox" ],
[ "myApp", "../../../myApp" ]
]
};
then i use this build script
./build.sh profile=../../../../myApp/myApp.profile.js releaseDir=../../../release
And I got the
</sites/somesite/scripts/release/content7>
which contains
--dijit
--dojo
--dojox
--myApp
NOW in my index.html file I have
<script type="text/javascript">
//<![CDATA[
var djConfig = {
parseOnLoad: true,
isDebug: false,
modulePaths: {
'myApp': '../myApp'
}
};
//]]>
</script>
<script type="text/javascript" src="scripts/release/content7/dojo/dojo.js"></script>
<script>
dojo.require('myApp.smartmix');
</script>
And YES this reduce the 230 files loaded without the build to 153 files.
BUT stills I (want to) believe that is posibble to reduce to one or 2 files.
But HOW?????
Please, some help will be appreciated!!!!
Ok, your profile is not right.
1st of all: You are using customBase, which is an advanced property for creating a minimal version of dojo core. I don't think you want that, do you? Normally, you just let dojo build its core normally, and that ends up as dojo.js in your output dir.
2nd of all: Every layer entry there will generate a minified .js file with all the files in dependencies inside it.
So, if you want your myApp stuff in a built JS file, you'll need to create a layer, and put your files in its dependencies.
Dojo will still generate all the individual files - but you don't have to deploy them. Just deploy the layer files. I usually have a layer for Dojo core, a layer for the dijit/dojox stuff I want, and then a layer for my custom JS. Then there are three JS files, which dojo will output in the dojo dir, and they are used in the HTML page.
...
layers: [
{
// this is a layer 'application', which will cache all
// dependencies to smartmix and declare smartmix in the same file
name: "../../../myApp/smartmix.js",
dependencies: [
"dojo.fx",
"dijit.form.Button",
"dojox.gauges.AnalogGauge",
"dojox.gauges.AnalogArcIndicator",
"dojox.gauges.AnalogNeedleIndicator",
"myApp.smartmix"
]
}
],
...
you will need only two requests;
<script src=..dojo.js></script>
and
<script>require(["myApp.smartmix"], function(smartmixApplication) { });</script>
