PurgeCSS is not enabled because you are in dev mode

Hey! Thanks for your work

Looks like I missed something.

I am using Tailwind CSS and here is my nuxt config:

modules: [ 'nuxt-purgecss' ],

purgeCSS: {
    mode: 'postcss',
    whitelist: ['html', 'body', 'nuxt-progress', 'is-active']
  },

build: {
    extractCSS: true,
    postcss: {
      plugins: {
        tailwindcss: './tailwind.config.js',
        autoprefixer: {}
      }
    }
...

I got “PurgeCSS is not enabled because you are in dev mode” regardless yarn dev or yarn build command I am using

What I am doing wrong? Thanks

I had the same problem. i got the “PurgeCSS is not enabled because you are in dev mode” on my remote app using CleverCloud. Of course I set up DEBUG to true and all env variables to production, but I was always getting an error saying I was in Dev mode… but I was in production. I think the error message is misleading because it check if (typeof purgeCSS.enabled === ‘undefined’) but that doesn’t mean we are in dev mode right ? I think the problem come from the enabled option with " ({ isDev, isClient }) => (!isDev && isClient) ". It doesn’t seem to work anymore. I was getting “undefined” while testing.

For people stuck like me, I ended up setting the enabled option in nuxt.config.js with one of my env variable.

purgeCSS: {
    enabled:  process.env.NODE_ENV == 'production' ? true : false ,
 },

I was able to fix the issue by upgrading all dependencies, not sure which one was causing the problem…
