Vue & Webpack - make files unreadable after build [duplicate] - vue.js

Question

My app is created with the vue cli. I can't find any option to disable source maps in production.
The npm build step in my package.json looks like this:
"build": "vue-cli-service build",
In angular, i can just add --prod to my build step to make it work.
Is there any such option for vue.js? Or do I have to change the webpack config (which is hidden by the cli)?

Answer 1

You make changes to the internal webpack config with the vue.config.js file at the project root (you may need to create it manually).
There is a productionSourceMap option so you can disable source maps when building for production:
module.exports = {
productionSourceMap: false
};

Answer 2

like #yuriy636 's answer, if you want only for production :
module.exports = {
productionSourceMap: process.env.NODE_ENV != 'production'
};

Answer 3

In my case the file vue.config.js wasn't taking effect. I had to change config/index.js changing productionSourceMap to false.
Please note that the project was generated a time ago. For the record, I am using a template from Vuetify.
