I am trying to upgrade an old framework I built in javascript to es6/module standards and I have a lot of troubles.
One of my current problems is that due to server side rendering my modules are sometime loaded in the node environment and are trying to access the window, causing errors.
Is there a principled way to manage this ?
The main jQuery file has a nice failback if window is undefined and can load in node without a fuss. I am trying to implement this in web-pack by I am stumbling.
This is my current webpack config
// @flow
// import path from 'path'
import webpack from 'webpack'
const WDS_PORT = 7000
const PROD = JSON.parse(process.env.PROD_ENV || '0')
const libraryName = 'experiment'
const outputFile = `${libraryName}${PROD ? '.min' : '.max'}.js`
const plugins = [
new webpack.optimize.OccurrenceOrderPlugin(),
]
const prodPlugins = plugins.concat(new webpack.optimize.UglifyJsPlugin())
// not really working
export default {
entry: './builder.js',
target: 'web',
output: {
path: `${__dirname}/lib`,
filename: outputFile,
library: libraryName,
libraryTarget: 'umd',
umdNamedDefine: true,
},
module: {
loaders: [
{
test: /(\.jsx|\.js)$/,
loader: 'babel-loader',
exclude: /(node_modules|bower_components)/,
},
],
},
devtool: PROD ? false : 'source-map',
resolve: {
extensions: ['.js', '.jsx'],
},
externals: {
chartjs: {
commonjs: 'chartjs',
amd: 'chartjs',
root: 'Chart', // indicates global variable
},
lodash: {
commonjs: 'lodash',
amd: 'lodash',
root: '_', // indicates global variable
},
jquery: 'jQuery',
mathjs: {
commonjs: 'mathjs',
amd: 'mathjs',
root: 'math', // indicates global variable
},
'experiment-boxes': {
commonjs: 'experiment-boxes',
amd: 'experiment-boxes',
root: 'experimentBoxes', // indicates global variable
},
'experiment-babylon-js': {
commonjs: 'experiment-babylon-js',
amd: 'experiment-babylon-js',
root: 'EBJS', // indicates global variable
},
},
devServer: {
port: WDS_PORT,
hot: true,
},
plugins: PROD ? prodPlugins : plugins,
}
And this is my main entry point builder.js
/* --- Import the framwork --- */
import TaskObject from './src/framework/TaskObject'
import StateManager from './src/framework/StateManager'
import State from './src/framework/State'
import EventData from './src/framework/EventData'
import DataManager from './src/framework/DataManager'
import RessourceManager from './src/framework/RessourceManager'
import {
Array,
String,
diag,
rowSum,
getRow,
matrix,
samplePermutation,
rep,
Deferred,
recurse,
jitter,
delay,
looksLikeAPromise,
mustHaveConstructor,
mustBeDefined,
mandatory,
debuglog,
debugWarn,
debugError,
noop,
} from './src/framework/utilities'
/* add it to the global space in case user want to import in a script tag */
if (typeof window !== 'undefined') {
window.TaskObject = TaskObject
window.StateManager = StateManager
window.State = State
window.EventData = EventData
window.DataManager = DataManager
window.RessourceManager = RessourceManager
window.jitter = jitter
window.delay = delay
window.Deferred = Deferred
}
export {
TaskObject,
StateManager,
State,
EventData,
DataManager,
RessourceManager,
Array,
String,
diag,
rowSum,
getRow,
matrix,
samplePermutation,
rep,
Deferred,
recurse,
jitter,
delay,
looksLikeAPromise,
mustHaveConstructor,
mustBeDefined,
mandatory,
debuglog,
debugWarn,
debugError,
noop,
}
Am I on the right track?
