Detailed instruction:

• Russian (русский язык) - https://habr.com/ru/articles/754878/

STEP 1.

Install AstroJS: instruction

STEP 2.

Add packages to help make your developing project better:

• editorconfig
• prettier
• eslint
• stylelint
• postcss
• AstroJS package to compress files: astro-compress

npm install --save-dev editorconfig-checker prettier prettier-plugin-astro eslint eslint-plugin-astro eslint-plugin-jsx-a11y typescript-eslint @eslint/js @types/eslint__js @typescript-eslint/parser stylelint stylelint-config-html stylelint-config-standard postcss-html stylelint-order autoprefixer postcss-preset-env cssnano astro-compress

STEP 3.

Add scripts to your package.json: copy it from the file package-scripts.json in this repository.

STEP 4.

Copy dot files from this repository to your AstroJS project: git clone https://github.com/teinett/astro-dot-files.git

Now move all files, excepting package-scripts.json and .vscode folder, to the root of your project.

STEP 5.

Add integrations and helpful settings to file astro.config.mjs.

• Add line prefetch: true, for faster page loading.

• Add @playform/compress to compress files: npm i @playform/compress.

• Add astro-purgecss to purge unused styles: npx astro add astro-purgecss

• Add sitemap integration: npm i @astrojs/sitemap.

• Add environment variables from the .env file.

• Change CSS specify strategy. Options: 'where' | 'class' | 'attribute'. I prefer 'class'.

As a result, we get the file astro.config.mjs

import { defineConfig } from "astro/config";
import sitemap from "@astrojs/sitemap";
import purgecss from "astro-purgecss";
import Compress from "@playform/compress";

import { loadEnv } from "vite";
const { FRONTEND_DOMAIN } = loadEnv(import.meta.env.MODE, process.cwd(), "");
// const { ASSETS_CDN_DOMAIN } = loadEnv(import.meta.env.MODE, process.cwd(), "");


export default defineConfig({
    site: FRONTEND_DOMAIN || "https://example.com",
    prefetch: true,
    scopedStyleStrategy: "class",
    integrations: [
        sitemap(),
        purgecss({
            variables: true,

            // for Astro view transitions
            keyframes: false,

            // for Astro view transitions
            safelist: {
                greedy: [
                    /*astro*/
                ],
            },

            // for SSR
            content: [process.cwd() + "/src/**/*.{astro,jsx,tsx,css}"],
        }),
        Compress({
            // CSS: false,
            // HTML: false,
            Image: false,
            // JavaScript: false,
            SVG: false,
        }), // should be last in the list
    ],
    build: {
        // assetsPrefix: ASSETS_CDN_DOMAIN,
    },
});

STEP 6.

Use VSCode editor?

Move all files from the copied .vscode folder to your local .vscode folder.

STEP 7.

Use TypeScript?

Edit file tsconfig.json: add aliases

{
  "extends": "astro/tsconfigs/strict",
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

STEP 8.

Use Astro Dev Toolbar?

Move file .astro/settings.json to root: it's Dev Toolbar settings.
