Build, test, and lint

• Use pnpm for all package management and repo scripts.
• Install dependencies: pnpm install
• Lint: pnpm run lint
• Type-check: pnpm run typecheck
• Build: pnpm run build
• Full test suite: pnpm run test
• Watch tests: pnpm run test:watch
• Run one test file: pnpm exec node --import tsx --test tests/serve.test.ts
• Run one test by name: pnpm exec node --import tsx --test --test-name-pattern "should return health status" tests/serve.test.ts
• CLI/manual smoke flows already scripted in package.json:
  • pnpm run test:bin
  • pnpm run test:serve
  • pnpm run test:serverPublish
  • pnpm run test:realPublish

High-level architecture

• This repository is a thin TypeScript CLI/server layer over @wenyan-md/core/wrapper. Rendering, theme management, credential storage, and WeChat publishing are mostly delegated to the core package; repo-local logic mainly handles command wiring, input resolution, and the HTTP server wrapper.
• src/cli.ts is the real entrypoint. It defines the publish, render, theme, serve, and credential commands with Commander, exports createProgram() for tests, and only calls program.parse() behind import.meta.main.
• src/utils.ts centralizes content ingestion. Input precedence is inline argument > file/URL via --file > stdin. File input is normalized with getNormalizeFilePath() and returns absoluteDirPath so core rendering can resolve relative assets correctly.
• src/commands/serve.ts implements the remote publish server used by wenyan publish --serve .... The flow is:
  1. /upload accepts Markdown, CSS, JSON, and image files into configDir/uploads
  2. clients reference uploaded assets via asset://...
  3. /publish loads an uploaded JSON render payload, rewrites asset:// references back to temp files, and calls publishToWechatDraft()
• The project supports both direct local publish and client-server publish. Local mode calls WeChat APIs from the CLI process; server mode pushes render/publish work to a remote Express server to avoid local IP whitelist issues.

Key conventions

• Keep the codebase in ESM TypeScript ("type": "module", moduleResolution: "NodeNext"). Prefer import/export, not CommonJS.
• Preserve the current error-handling split:
  • CLI commands should go through the shared runCommandWrapper() pattern and exit with code 1 on failure.
  • Server routes should throw AppError for expected client errors so the shared JSON error shape stays { code: -1, desc }.
• Preserve user-facing Chinese success/error messages unless there is a strong reason to change them. Tests assert on specific Chinese output and error text.
• When adding input-related behavior, keep the existing precedence rules and do not break stdin-based usage for CI/CD pipelines.
• Server uploads are temporary and live under configDir/uploads with a 10-minute TTL cleanup job. Features that rely on uploaded files should fit that lifecycle instead of introducing permanent storage here.
• Publishing assumes Wenyan article metadata conventions from the README: Markdown frontmatter should provide at least title, with optional cover, author, and source_url. WeChat publishing also depends on WECHAT_APP_ID and WECHAT_APP_SECRET unless credentials are managed through the CLI/server credential flow.
• Tests use the native Node test runner (node:test) plus node:assert/strict and mock. Follow the existing style instead of introducing Jest/Vitest.
