Vue js in cordova - javascript

I'm struggling to implement a simple Vue.js app into Cordova. Everything works fine except that I don't know how I can intercept cordova events (deviceready, pause, ...) into my vue application. I used the Webpack template from vue-cli.
Here's my file js/index.js :
const app = {
initialize: function () {
console.log('initialize')
this.bindEvents()
},
bindEvents: function () {
document.addEventListener('deviceready', this.onDeviceReady, false)
},
onDeviceReady: function () {
app.receivedEvent('deviceready')
},
receivedEvent: function (id) {
console.log('Received Event: ' + id)
}
}
app.initialize()
the src/main.js :
import Vue from 'vue'
import App from './App'
/* eslint-disable no-new */
const app = new Vue({
template: '<App/>',
components: { App }
})
app.$mount('#app')
config/index.js :
module.exports = {
build: {
env: require('./prod.env'),
index: path.resolve(__dirname, '../dist/index.html'),
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
//assetsPublicPath: '/',

},

What shoud I do to get events from Cordova to my Vue components ?

See this article, it worked for me:
https://coligo.io/building-a-mobile-app-with-cordova-vuejs/
To allow the app to access the Vue.js library, we also need to add the following to the end of the Content Security Policy (CSP) meta tag in www/index.html:
; script-src 'self' http://cdn.jsdelivr.net/vue/1.0.16/vue.js 'unsafe-eval'

Looks like the issue was that Cordova.js is not included in browser, you need to test on a physical device.
That doesn't mean you can't prototype in the browser though. In JS, window.cordova will be defined if cordova has loaded. So you can setup your initialization like so
if(window.cordova){
//add deviceready event to start app
} else {
//call starting function
}
For things requiring a physical device: vibration, accelerometer, etc, you have to build and deploy to a device, the browser itself is not enough.

Thanks for your interest towards Syncfusion controls.
We recommend you to configure aurelia-syncfusion-bridge resources in webpack.config.js file. Because aurelia-syncfusion-bridge’s resources are traced by aurelia-webpack-plugin and included in app.bundle.
Suppose If we add this plugin in webpack.vendor.js, we need to bundle manually for every additional aurelia-syncfusion-bridge’s resources for proper bundling. Since, we recommend to configure our bridge in webpack.config.js, which will automatically bundle the bridge source along with application bundle.
We have prepared sample for the same and attached below.
Sample
Please let us know if you need further assistance on this.
Thanks,

Adding Bluebird to aurelia project does not work

This might be another beginner question
I set up a Project using JavaScript Services aurelia SPA template. Running this project in IE11 throws a unhandled runtime exception: "Promise" is undefined.
Unhandled exception at line 1923, column 3 in
http://localhost:54195/dist/app.js?v=eXMK1e2R-1iC7sDJ1TzKClbGOJAKb11N-KPl95g30Fg
0x800a1391 - Laufzeitfehler in JavaScript: "Promise" ist undefiniert
occurred
To solve this I try to add the Bluebird library as suggested in several posts. But I cannot get it to run. I get always the same error. Apparently the error occurs in aurelia-bootstrapp-webpack.js line 36 (function ready()). Obviously the Bluebird library still does not get recognized. Here is what I have so far:

import { Router, RouterConfiguration } from 'aurelia-router';
export class App {

configureRouter(config: RouterConfiguration, router: Router) {
config.title = 'Aurelia';
config.map([{
route: [ '', 'home' ],
name: 'home',
settings: { icon: 'home' },
moduleId: '../home/home',
nav: true,
title: 'Home'
}, {
route: 'counter',
name: 'counter',

moduleId: '../counter/counter',

settings: { icon: 'th-list' },
moduleId: '../fetchdata/fetchdata',
nav: true,

}]);
this.router = router;
}
}
After some research, I found a solution. That was adding bluebird to the plugins in webpack.config.js:
plugins: [
new webpack.ProvidePlugin({ Promise: "bluebird" }),
new webpack.DefinePlugin({ IS_DEV_BUILD: JSON.stringify(isDevBuild) }),
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./wwwroot/dist/vendor-manifest.json')
}),
new AureliaWebpackPlugin({
root: path.resolve('./'),
src: path.resolve('./ClientApp'),
baseUrl: '/'
})
]
The ProvidePlugin seems to inject Bluebird into every package.

Webpack babel config for both server and client javascript?

I'm trying to figure out how to have a single webpack config file that works for transforming both server (node.js) js and client js with the es2015 preset. Currently I have to specifically set "target: 'node'" for it to correctly process node-based files. If I don't, then webpack does the transformation based on the default "target: 'web'". It then reports errors because the 'mysql' module being imported clearly won't work for web.
How can I unify both into the same config file so that server and client js will be transformed separately? Or do I need separate configs entirely?
Sample webpack.config.js
'use strict';
var path = require('path');
var webpack = require('webpack');
module.exports = {
target: 'node',
resolve: {
root: path.resolve(__dirname),
extensions: ['', '.js']
},
entry: [
'babel-polyfill',
'./index.js',
],
output: {
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /\.js$/,
exclude: /node_modules/,
loader: 'babel',
query: {
presets: ['es2015']
}
}
]
}
};
Sample js code
import 'babel-polyfill';
import mysql from 'mysql';
class Test {
constructor () {
}
get read () {
}
};
You can pass multiple configs for Webpack to process at the same time. Simply return an array of configuration objects.
export default [
{
// config 1 here
},
{
// config 2 here
},
];
Extra tip: if you use .babel.js as extension for your config file, Webpack will run it through Babel for you, which allows you to use ES6 in your Webpack config.

That is the config we use in one of our sites with a partially shared codebase, and partially shared assets. It consists of three Webpack builds in one:
Browser
Server assets (images/fonts/... that will be referenced in server-generated HTML)
Server code (Node)
The server code has a few special properties:
target: 'node' (Webpack needs this)
output.libraryTarget: 'commonjs' (makes Webpack use commonjs for unbundled libs)
externals: [ /^(?!\.|\/).+/i, ] (makes Webpack not bundle anything in node_modules, or anything that is not a relative path (starting with . or /)
This combination makes Webpack only process your own code, and access other modules and libraries through require. Which means your dependencies using native bindings won't break as they won't be bundled.

Preferred way of using Bootstrap in Webpack

Greetings one and all,
I have been playing around with Bootstrap for Webpack, but I'm at the point of tearing my hair out. I have literally gone through loads of blog articles and they either use the 7 months outdated 'bootstrap-webpack' plugin (which, surprisingly does not work out of the box) or.. They include the Bootstrap files through import 'node_modules/*/bootstrap/css/bootstrap.css'.
Surely, there must be a cleaner and more efficient way of going about this?
This is my current webpack.config.js file:
var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var autoprefixer = require('autoprefixer');
var path = require('path');
module.exports = {
entry: {
app: path.resolve(__dirname, 'src/js/main.js')
},
module: {
loaders: [{
test: /\.js[x]?$/,
loaders: ['babel-loader?presets[]=es2015&presets[]=react'],
exclude: /(node_modules|bower_components)/
}, {
test: /\.css$/,
loaders: ['style', 'css']
}, {
test: /\.scss$/,
loaders: ['style', 'css', 'postcss', 'sass']
}, {
test: /\.sass$/,
loader: 'style!css!sass?sourceMap'
},{
test: /\.less$/,
loaders: ['style', 'css', 'less']
}, {
test: /\.woff$/,
loader: "url-loader?limit=10000&mimetype=application/font-woff&name=[path][name].[ext]"
}, {
test: /\.woff2$/,
loader: "url-loader?limit=10000&mimetype=application/font-woff2&name=[path][name].[ext]"
}, {
test: /\.(eot|ttf|svg|gif|png)$/,
loader: "file-loader"
}]
},
output: {
path: path.resolve(__dirname, 'dist'),
filename: '/js/bundle.js',
sourceMapFilename: '/js/bundle.map',
publicPath: '/'
},
plugins: [
new ExtractTextPlugin('style.css')
],
postcss: [
autoprefixer({
browsers: ['last 2 versions']
})
],
resolve: {
extensions: ['', '.js', '.sass'],
modulesDirectories: ['src', 'node_modules']
},
devServer: {
inline: true,
contentBase: './dist'
}
};
I could go and require('bootstrap') (with some way of getting jQuery in it to work), but.. I'm curious to what you all think and do.
Thanks in advance :)
I am not sure if this is the best way, but following work for me well with vue.js webapp. You can see the working code here.
I have included files required by bootstrap in index.html like this:
<head>
<meta charset="utf-8">
<title>Hey</title>
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, minimal-ui">
<link rel="stylesheet" href="/static/bootstrap.css" type="text/css">
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.3.7/js/tether.min.js" integrity="sha384-XTs3FgkjiBgo8qjEjBk0tGmf3wPrWtA6coPfQDfFEY8AnYJwjalXCiosYRBIBZX8" crossorigin="anonymous"></script>
<script href="/static/bootstrap.js"></script>
</head>
And this works, you can execute the repo. Why I went this way was I had to customise some config in bootstrap so I had to change the variables file and build the code of bootstrap which outputted me bootstrap.js and bootstrap.cssfiles, which I am using here.
There is an alternative way suggested here by using the npm package and a webpack customisation.
First install bootstrap in your project:
npm install bootstrap#4.0.0-alpha.5
And make sure you can use sass-loader in your components:
npm install sass-loader node-sass --save-dev
now go to your webpack config file and add a sassLoader object with the following:
sassLoader: {
includePaths: [
path.resolve(projectRoot, 'node_modules/bootstrap/scss/'),
],
},
projectRoot should just point to where you can navigate to node_packages from, in my case this is: path.resolve(__dirname, '../')
Now you can use bootstrap directly in your .vue files and webpack will compile it for you when you add the following:
<style lang="scss">
#import "bootstrap";
</style>
I highly recommend using bootstrap-loader. You add a config file (.bootstraprc in your root folder) where you can exclude the bootstrap elements you don't want and tell where your variables.scss and bootstrap.overrides.scss are. Define you SCSS variables, do your overrides, add your webpack entry and get on with your life.
I use webpack to build bootstrap directly from .less and .scss files. This allows customizing bootstrap by overriding the source in .less/.scss and still get all the benefits of webpack.
Your code is missing an entry point for any .css/.less/.scss files. You need to include an entry point for the compiled css files. For this entry point, I declare an array with const and then include paths inside the array to the source files I want webpack to compile.
Currently, I'm using bootstrap 3 with a base custom template and also a 2nd custom theme. The base template uses bootstrap .less file styling and it has specific source overrides written in .less files.
The 2nd custom theme uses .sass file styling and has similar overrides to bootstrap's base written in .scss files. So, I need to try to optimize all this styling for production (currently coming in about 400kb but that's a little heavy because we choose to avoid CDN's due to targeting use in China).
Below is a reference webpack.config.js which works to build from .less/.scss/.css files, and also does a few other things like build typescript modules and uses Babel for converting es6/typescript to browser compatible javascript. The output ultimately ends up in my /static/dist folder.

webpack dev server does not show the content

I have the following problem when running the webpack dev server:
when I run npm start, it show the following:
➜ directory git:(staging) ✗ npm start
directory #1.0.0 start directory
BUILD_DEV=1 BUILD_STAGING=1 ./node_modules/webpack-dev-server/bin/webpack-dev-server.js
http://localhost:8080/
webpack result is served from /undefined/
content is served from
directory
404s will fallback to /index.html
Hash: 75773622412153d5f921
Version: webpack 1.12.11
Time: 43330ms
I guess the problem might because the following line:
webpack result is served from /undefined/
When I open the browser at http://localhost:8080/, it appear as follow:
Cannot GET /
and there is no thing in the console.
Do you have any ideas for this problem ?

Same problem occurred to me when i started using babel-loader > 6.
It was fixed by adding contentBase in webpack dev server configuration.
In my case it looked like this
new WebPackDevServer(webpack(config), {
publicPath: config.output.publicPath,
hot: true,
historyApiFallback: true,
contentBase: __dirname + '/public'
}).listen(3000, 'localhost')
I would be great to see your webpack config file to pin point the exact problem, but from the error message, there could be multiple problem
Make sure you are on the right port
Make sure your webpack config has
path and public path setup
Make sure you have contentBase setup as
well
Without seeing your webpack file and more concrete detail, it is quite hard to pinpoint the issue. But you can always go to https://webpack.github.io/docs/webpack-dev-server.html for information on how to set it up.
