+# Source Maps
+
+Generate source maps for debugging bundled code.
+
+## Overview
+
+Source maps map minified/bundled code back to original source files, making debugging significantly easier by showing original line numbers and variable names.
+
+## Basic Usage
+
+### CLI
+
+```bash
+tsdown --sourcemap
+
+# Or inline
+tsdown --sourcemap inline
+```
+
+### Config File
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  sourcemap: true,
+})
+```
+
+## Source Map Types
+
+### External (default)
+
+Generates separate `.map` files:
+
+```ts
+export default defineConfig({
+  sourcemap: true,  // or 'external'
+})
+```
+
+**Output:**
+- `dist/index.mjs`
+- `dist/index.mjs.map`
+
+**Pros:**
+- Smaller bundle size
+- Can be excluded from production
+- Faster parsing
+
+### Inline
+
+Embeds source maps in the bundle:
+
+```ts
+export default defineConfig({
+  sourcemap: 'inline',
+})
+```
+
+**Output:**
+- `dist/index.mjs` (includes source map as data URL)
+
+**Pros:**
+- Single file deployment
+- Guaranteed to be available
+
+**Cons:**
+- Larger bundle size
+- Exposed in production
+
+### Hidden
+
+Generates map files without reference comment:
+
+```ts
+export default defineConfig({
+  sourcemap: 'hidden',
+})
+```
+
+**Output:**
+- `dist/index.mjs` (no `//# sourceMappingURL` comment)
+- `dist/index.mjs.map`
+
+**Use when:**
+- You want maps for error reporting tools
+- But don't want them exposed to users
+
+## Auto-Enable Scenarios
+
+### Declaration Maps
+
+If `declarationMap` is enabled in `tsconfig.json`, source maps are automatically enabled:
+
+```json
+// tsconfig.json
+{
+  "compilerOptions": {
+    "declarationMap": true
+  }
+}
+```
+
+This also generates `.d.ts.map` files for TypeScript declarations.
+
+## Common Patterns
+
+### Development Build
+
+```ts
+export default defineConfig((options) => ({
+  entry: ['src/index.ts'],
+  sourcemap: options.watch,  // Only in dev
+  minify: !options.watch,
+}))
+```
+
+### Production with External Maps
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  sourcemap: true,  // External maps
+  minify: true,
+})
+```
+
+Deploy maps to separate error reporting service.
+
+### Always Inline (Development Tool)
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm'],
+  sourcemap: 'inline',
+})
+```
+
+### Per-Format Source Maps
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: {
+    esm: {
+      sourcemap: true,
+    },
+    iife: {
+      sourcemap: 'inline',  // Inline for browser
+    },
+  },
+})
+```
+
+### TypeScript Library with Declaration Maps
+
+```ts
+export default defineConfig({
+  entry: ['src/index.ts'],
+  format: ['esm', 'cjs'],
+  sourcemap: true,
+  dts: {
+    sourcemap: true,  // Enable declaration maps
+  },
+})
+```
+
+**Output:**
+- `dist/index.mjs` + `dist/index.mjs.map`
+- `dist/index.cjs` + `dist/index.cjs.map`
+- `dist/index.d.ts` + `dist/index.d.ts.map`
+
+## Benefits
+
+### For Development
+
+- **Faster debugging** - See original code in debugger
+- **Better error messages** - Stack traces show original lines
+- **Easier breakpoints** - Set breakpoints on source code
+
+### For Production
+
+- **Error reporting** - Send accurate error locations to services
+- **Monitoring** - Track errors back to source
+- **Support** - Help users report issues accurately
+
+## Performance Impact
+
+| Type | Bundle Size | Parse Speed | Debugging |
+|------|-------------|-------------|-----------|
+| None | Smallest | Fastest | Hard |
+| External | Small | Fast | Easy |
+| Inline | Largest | Slower | Easy |
+| Hidden | Small | Fast | Tools only |
+
+## CLI Examples
+
+```bash
+# Enable source maps
+tsdown --sourcemap
+
+# Inline source maps
+tsdown --sourcemap inline
+
+# Hidden source maps
+tsdown --sourcemap hidden
+
+# Development with source maps
+tsdown --watch --sourcemap
+
+# Production with external maps
+tsdown --minify --sourcemap
+
+# No source maps
+tsdown --no-sourcemap
+```
+
+## Use Cases
+
+### Local Development
+
+```ts
+export default defineConfig({
+  sourcemap: true,
+  minify: false,
+})
+```
+
+### Production Build
+
+```ts
+export default defineConfig({
+  sourcemap: 'external',  // Upload to error service
+  minify: true,
+})
+```
+
+### Browser Library
+
+```ts
+export default defineConfig({
+  format: ['iife'],
+  platform: 'browser',
+  sourcemap: 'inline',  // Self-contained
+  globalName: 'MyLib',
+})
+```
+
+### Node.js CLI Tool
+
+```ts
+export default defineConfig({
+  format: ['esm'],
+  platform: 'node',
+  sourcemap: true,
+  shims: true,
+})
+```
+
+## Troubleshooting
+
+### Source Maps Not Working
+
+1. **Check output** - Verify `.map` files are generated
+2. **Check reference** - Look for `//# sourceMappingURL=` comment
+3. **Check paths** - Ensure relative paths are correct
+4. **Check tool** - Verify debugger/browser supports source maps
+
+### Large Bundle Size
+
+Use external source maps instead of inline:
+
+```ts
+export default defineConfig({
+  sourcemap: true,  // Not 'inline'
+})
+```
+
+### Source Not Found
+
+- Ensure source files are accessible relative to map
+- Check `sourceRoot` in generated map
+- Verify paths in `sources` array
+
+## Tips
+
+1. **Use external maps** for production (smaller bundles)
+2. **Use inline maps** for single-file tools
+3. **Enable in development** for better DX
+4. **Upload to error services** for production debugging
+5. **Use hidden maps** when you want them for tools only
+6. **Enable declaration maps** for TypeScript libraries
