契约

  1. compile is a function exported by @tailwindcss/node and wrapper module
  2. createCompiler returns a compiler object with build and buildSourceMap methods
  3. compiler.build(candidates) generates CSS rules for standard utility classes
  4. compiler.build(candidates) generates CSS rules for arbitrary value utilities
  5. compiler.build(candidates) generates CSS rules for variants such as hover and focus
  6. compiler.build(candidates) generates responsive variant media queries
  7. compiler.build(candidates) generates CSS rules for custom utilities defined in input stylesheet
  8. compiler.build(candidates) ignores unrecognized or invalid utility classes
  9. compiler.buildSourceMap() returns a decoded source map with mappings
  10. compileAndBuild helper compiles and builds CSS candidates directly
  11. compile tracks imported stylesheets and dependencies via onDependency callback

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify @tailwindcss/node.compile in pkg:npm/%40tailwindcss/node@4.3.3
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tailwindcss/node@4.3.3
Demonstrate these symbols/APIs:
  - @tailwindcss/node.compile
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
