Manual Installation 🧑‍💻

1. Install package astro-min

2. Import and add to integrations list

//astro.config.mjs
import { defineConfig } from 'astro/config'
import min from 'astro-min'

export default defineConfig({
  integrations: [min()]
})

Options 🔧

//astro.config.mjs
import { defineConfig } from 'astro/config'
import minify from 'astro-min'

export default defineConfig({
  integrations: [
    minify({
      do_not_minify_doctype: false,
      ensure_spec_compliant_unquoted_attribute_values: false,
      keep_closing_tags: false,
      keep_comments: false,
      keep_html_and_head_opening_tags: false,
      keep_input_type_text_attr: false,
      keep_spaces_between_attributes: false,
      keep_ssi_comments: false,
      minify_css: false,
      minify_js: false,
      preserve_brace_template_syntax: false,
      preserve_chevron_percent_template_syntax: false,
      remove_bangs: false,
      remove_processing_instructions: false,
    })
  ]
})

[!IMPORTANT]

Use astro-min last in your integration list for the best optimization
Optional: but before astro-compressor and astro-compress for images only

//astro.config.mjs
import { defineConfig } from 'astro/config'
import compressor from 'astro-compressor'
import minify from 'astro-min'

export default defineConfig({
  integrations: [
    minify({
      // do_not_minify_doctype: false,
      // ensure_spec_compliant_unquoted_attribute_values: false,
      // keep_closing_tags: false,
      // keep_comments: false,
      // keep_html_and_head_opening_tags: false,
      // keep_input_type_text_attr: false,
      // keep_spaces_between_attributes: false,
      // keep_ssi_comments: false,
      // minify_css: false,
      // minify_js: false,
      // preserve_brace_template_syntax: false,
      // preserve_chevron_percent_template_syntax: false,
      // remove_bangs: false,
      // remove_processing_instructions: false,
    }),
    compress({
      CSS: false,
      HTML: false,
      Image: true,
      JavaScript: false,
      SVG: false
    }),
    compressor()
  ]
})
