wl-web-configs

Workleap's shared configuration library for web tooling. Provides pre-configured packages for ESLint, TypeScript, Rsbuild, Rslib, Stylelint, and Browserslist.

Philosophy

• No lock-in: Default configurations can always be extended or overridden
• By project type: Configurations are composed internally and offered per project type for simplicity
• ESM/ESNext by default: Targets modern JavaScript environments
• Distributed via NPM: Easy to adopt new features by bumping package versions

Supported Tools (Active)

Tool	Package	Purpose
Browserslist	@workleap/browserslist-config	Browser targets for apps
ESLint	@workleap/eslint-configs	Code linting
Stylelint	@workleap/stylelint-configs	CSS linting
TypeScript	@workleap/typescript-configs	Type checking (linting only)
Rsbuild	@workleap/rsbuild-configs	Web application bundling
Rslib	@workleap/rslib-configs	Library bundling

In maintenance mode (do not recommend): PostCSS, SWC, webpack, tsup

Quick Reference

Which Configuration to Use?

Project Type	ESLint	TypeScript	Bundler
Web app with React	defineWebApplicationConfig	web-application.json	@workleap/rsbuild-configs
React library	defineReactLibraryConfig	library.json	@workleap/rslib-configs
TypeScript library (no React)	defineTypeScriptLibraryConfig	library.json	@workleap/rslib-configs
Monorepo workspace root	defineMonorepoWorkspaceConfig	monorepo-workspace.json	N/A

Browserslist (Apps Only)

pnpm add -D @workleap/browserslist-config browserslist

# .browserslistrc
extends @workleap/browserslist-config

Only for projects emitting application bundles. Libraries should NOT include Browserslist.

To add custom browser targets while still using the shared config:

# .browserslistrc
extends @workleap/browserslist-config

Reference Guide

For comprehensive setup guides, options, and examples, read the appropriate reference file:

• ESLint — references/eslint.md: Installation, define*Config functions, rule categories, customization, and VS Code integration
• TypeScript — references/typescript.md: Config files by project type, compiler option overrides, path mappings, and CLI scripts
• Rsbuild — references/rsbuild.md: Dev/build/Storybook configs, predefined options, transformers, and Turborepo setup
• Rslib — references/rslib.md: Library build/dev/Storybook configs, bundleless vs bundle, transformers, and type declarations
• Stylelint — references/stylelint.md: Installation, .stylelintrc.json setup, Prettier integration, and VS Code settings

Critical Rules

1. Never invent APIs: Only suggest documented options and patterns
2. Respect maintenance mode: Do not recommend PostCSS, SWC, webpack, or tsup configs
3. ESM by default: All configs target ESM/ESNext unless migrating legacy code
4. Browserslist for apps only: Libraries should not include Browserslist config
5. TypeScript for linting: The shared TypeScript configs focus on linting; bundlers handle transpilation
