How to configure Production build and Development Build vue-cli - vue.js

Question

I want to setup a npm script for production build and one for development build. like npm run build for production and npm run buildDev for development.
I have some configurations in each env file like:
ROOT_API: '"url for the production"' and something else in the development env.
The build will be added to the dist folder.
I want the Production Build to be added to the dist folder and the Development Build to be added to a distDev folder.
I have tried to make a copy of the build.js file but without luck.
config/index.js:
'use strict'
// see http://vuejs-templates.github.io/webpack for documentation.
const path = require('path')
module.exports = {
build: {
env: require('./prod.env'),
index: path.resolve(__dirname, '../dist/index.html'),
assetsRoot: path.resolve(__dirname, '../dist'),
assetsSubDirectory: 'static',
assetsPublicPath: '/',
productionSourceMap: true,
// Gzip off by default as many popular static hosts such as
// Surge or Netlify already gzip all static assets for you.
// Before setting to `true`, make sure to:
// npm install --save-dev compression-webpack-plugin
productionGzip: false,
productionGzipExtensions: ['js', 'css'],
// Run the build command with an extra argument to
// View the bundle analyzer report after build finishes:
// `npm run build --report`
// Set to `true` or `false` to always turn it on or off
bundleAnalyzerReport: process.env.npm_config_report
},
dev: {
env: require('./dev.env'),
port: 8080,
autoOpenBrowser: true,
assetsSubDirectory: 'static',
assetsPublicPath: '/',
proxyTable: {},
// CSS Sourcemaps off by default because relative paths are
"buggy"
// with this option, according to the CSS-Loader README
// (https://github.com/webpack/css-loader#sourcemaps)
// In our experience, they generally work as expected,
// just be aware of this issue when enabling this option.
cssSourceMap: false
}
}
config/prod.env.js
module.exports = {
NODE_ENV: '"production"',
ROOT_API: '"url for production"'
}
config/dev.env.js
'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
ROOT_API: '"url for development"'
})
build/build.js
'use strict'
require('./check-versions')()
process.env.NODE_ENV = 'production'
const ora = require('ora')
const rm = require('rimraf')
const path = require('path')
const chalk = require('chalk')
const webpack = require('webpack')
const config = require('../config')
const webpackConfig = require('./webpack.prod.conf')
const spinner = ora('building for production...')
spinner.start()
rm(path.join(config.build.assetsRoot,
config.build.assetsSubDirectory), err => {
if (err) throw err
webpack(webpackConfig, function (err, stats) {
spinner.stop()
if (err) throw err
process.stdout.write(stats.toString({
colors: true,
modules: false,
children: false,
chunks: false,
chunkModules: false
}) + '\n\n')
console.log(chalk.cyan(' Build complete.\n'))
console.log(chalk.yellow(
' Tip: built files are meant to be served over an HTTP
server.\n' +
' Opening index.html over file:// won\'t work.\n'
))
})
})
Any suggestions?

Answer 1

Didn't you try to use vue.config.js file to configure Vue build behavior?
You could specify an outputDir according to process.env.NODE_ENV at vue.config.js.
All environment-specific parameters would be set at .env.development and .env.production files accordingly.
Of course you can modify Webpack config through vue.config.js if you need, examples here.
Output directory parameter changing example is here.
At the end, your configuration file will depend only on environment variables and maybe some logic, e.g.:
module.exports = {
NODE_ENV: process.env.NODE_ENV,
ROOT_API: process.env.VUE_APP_ROOT_API_URL,
ANY_PARAM: process.env.VUE_APP_ANY_DOT_ENV_PARAM,
}
But remember, that your custom .env params should start with VUE_APP_ prefix, if you use them at templates.

Add --mode development entry in your package.json file like this:
