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)

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

Quick Reference

Which Configuration to Use?

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
IE 11
last 2 OperaMobile 12.1 versions

Detailed Documentation

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

• ESLint: See references/eslint.md
• TypeScript: See references/typescript.md
• Rsbuild: See references/rsbuild.md
• Rslib: See references/rslib.md
• Stylelint: See references/stylelint.md

Common Patterns

Customizing Default Rules

All define* functions accept a second argument for customization:

// ESLint example
export default defineWebApplicationConfig(import.meta.dirname, {
    core: { "no-var": "off" },
    typescript: { "@stylistic/quote-props": "off" }
});

// TypeScript example - tsconfig.json
{
    "extends": ["@workleap/typescript-configs/web-application.json"],
    "compilerOptions": { "strict": false },
    "exclude": ["dist", "node_modules"]
}

Configuration Transformers (Advanced)

For full control over Rsbuild/Rslib configs:

import { defineDevConfig, type RsbuildConfigTransformer } from "@workleap/rsbuild-configs";

const customTransformer: RsbuildConfigTransformer = (config) => {
    config.tools = config.tools ?? {};
    // modify config
    return config;
};

export default defineDevConfig({
    transformers: [customTransformer]
});

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
