Answer 1

Update Config
There are several experimental ways of improving build speed.
https://nuxtjs.org/api/configuration-build#parallel
https://nuxtjs.org/api/configuration-build#cache
https://nuxtjs.org/api/configuration-build#hardsource
build: {
// standalone: true,
analyze: false,
parallel: true,
cache: true,
hardSource: false,
splitChunks: {
layouts: false,
pages: false,
components: false,
},
html: {
minify: {
minifyCSS: false,
minifyJS: false
}
},
loaders: {
vue: {
prettify: false
}
},
transpile: ["#coreui/vue", "#coreui/utils", "#ag-grid-community/vue"],
extend(config, ctx) {
if (ctx.isDev) {
config.devtool = ctx.isClient ? "source-map" : "inline-source-map";
}
}
}
