Disabling debug mode when building production : Vue 2

[Bhanu_Kumar_Singh]

I have setup vue in my project using the following answer:

Adding Vue.js to Sage 9: Dependencies and Approach

Updated instructions for buble instead of babel, with vue-style-loader working The previous solution above was missing vue-style-loader integration, and this one fixes that problem, permitting <style> sections in .vue single-file components. Thanks to @kellymears for having published https://github.com/pixelcollective/SageJS, which includes these fixes. Known issue: In the final main.css, the styles from .vue components are included before the normal scss styles. Now sure how to fix that yet. …

Vue is working perfectly fine but I am interested in disabling vue devtools (debug mode) when use a production build.

I found this at some place but I am not very sure about how to webpack.

if (process.env.MIX_APP_ENV === 'production') {
    Vue.config.devtools = false;
    Vue.config.debug = false;
    Vue.config.silent = true; 
}

This probably is a laravel Mix file. How can I do these in sage ?

Thanks in advance!!
