postcss-config-nick2bad4u

Context-aware PostCSS presets for modern CSS, Tailwind CSS, assets, and production optimization. Every path is resolved from the consuming project; the package never assumes that its own installation directory is the project root.

Install

npm install --save-dev postcss postcss-config-nick2bad4u

Install Tailwind CSS when using the Tailwind or full profile:

npm install --save-dev tailwindcss

Basic configuration

Use the base preset as a postcss.config.mjs function so postcss-load-config can supply its current environment and working directory:

import createPostcssConfig from "postcss-config-nick2bad4u";

export default (context) => createPostcssConfig({}, context);

The root export and postcss-config-nick2bad4u/base both provide the base profile. It includes imports, logical properties, flexbug fixes, and Autoprefixer in a stable semantic order.

Profiles

Each subpath supplies a focused default factory:

• postcss-config-nick2bad4u/base — portable modern-CSS defaults.
• postcss-config-nick2bad4u/tailwind — base plus the Tailwind PostCSS plugin.
• postcss-config-nick2bad4u/assets — base plus asset URL and inline-SVG handling.
• postcss-config-nick2bad4u/production — base plus safe cssnano defaults.
• postcss-config-nick2bad4u/full — Tailwind, assets, normalization, and environment-aware reporting or minification.

For example:

import createFullConfig from "postcss-config-nick2bad4u/full";

export default (context) =>
 createFullConfig(
  {
   projectRoot: import.meta.dirname,
   assetLoadPaths: ["public", "src/assets"],
   browsers: ["defaults and fully supports es6-module"],
  },
  context
 );

The full profile uses cssnano only when context.env or options.env is production. In other environments it appends postcss-reporter instead.

Production safety

The production preset intentionally uses cssnano's default preset. Selector combining, media-query sorting, and the advanced cssnano preset can alter CSS semantics, so each requires an explicit option:

import createProductionConfig from "postcss-config-nick2bad4u/production";

export default createProductionConfig({
 advancedMinification: true,
 combineDuplicateSelectors: true,
 sortMediaQueries: true,
});

Review the generated CSS before enabling these optimizations in an existing application.

Extending the pipeline

Use named insertion points instead of rebuilding the preset's ordering:

import createPostcssConfig from "postcss-config-nick2bad4u";
import customProperties from "postcss-custom-properties";

export default createPostcssConfig({
 additionalPlugins: {
  beforeOptimization: [customProperties()],
 },
 profile: "production",
});

Plugins in before run before imports. beforeOptimization runs after normal transforms and assets but before optional optimizers. after runs last, including after cssnano, and should be reserved for plugins that explicitly need that position.

Validation

npm run release:verify

This builds the ESM package, runs both TypeScript generations, exercises the configuration through PostCSS, checks coverage and formatting, and validates the packed public surface with publint and Are the Types Wrong.
