 # Changelog
 
+## 2026-01-23 - 2.8.3 - fix(mod_output)
+use pattern base dir when computing relative paths for files to serve
+
+- Compute relativePath using the pattern base directory (dirPath) instead of this.cwd to ensure correct web-serving paths for absolute or relative entry.path values.
+- File changed: ts/mod_output/index.ts — replaces plugins.path.relative(this.cwd, fullPath) with plugins.path.relative(dirPath, fullPath) and adds clarifying comment.
+
+## 2026-01-23 - 2.8.2 - fix(mod_output)
+resolve absolute and relative entry.path correctly when adding files
+
+- Add check for plugins.path.isAbsolute(entry.path) to avoid incorrectly joining absolute paths with dirPath
+- Use entry.path directly when it's absolute, otherwise join with dirPath
+- Ensures correct relativePath calculation and prevents invalid file reads
+
+## 2026-01-12 - 2.8.1 - fix(readme)
+document maxLineLength option for base64ts output and add example and tip
+
+- Add documented `maxLineLength` configuration option (number, default 0 = unlimited) for `base64ts` output.
+- Include example config showing `maxLineLength: 200`.
+- Add a tip recommending setting `maxLineLength` to split long base64 strings when using AI tools with line-length limits.
+
+## 2026-01-12 - 2.8.0 - feat(tsbundle)
+add configurable maxLineLength for base64ts output and improve build/error handling in child builds
+
+- Add optional maxLineLength?: number to IBundleConfig to control max characters per line for base64ts output (0 or undefined = unlimited).
+- Support splitting base64 strings when maxLineLength is specified; generateTypeScript(maxLineLength?) and writeToFile(outputPath, maxLineLength?) updated to accept and apply this setting.
+- Pass bundleConfig.maxLineLength through in mod_custom so base64ts output respects bundle configuration.
+- Wrap TsBundle.build in mod_custom with try/catch to log failures and skip output handling when build fails.
+- tsbundle.class now rejects the bundle promise when the child process exits with a non-zero status.
+- mod_esbuild child process now awaits builds, exits with appropriate success/failure codes, and formats esbuild errors for clearer console output.
+
+## 2026-01-12 - 2.7.4 - fix(deps)
+bump @push.rocks/smartcli dependency to ^4.0.20
+
+- @push.rocks/smartcli: ^4.0.19 → ^4.0.20
+- Patch-level dependency update with no breaking changes
+
+## 2026-01-12 - 2.7.3 - fix(mod_output)
+wrap long base64 file contents and format generated TypeScript output to avoid extremely long lines
+
+- Introduce MAX_LINE_LENGTH (200) and formatBase64 to split long base64 strings into chunks and join them with string concatenation
+- Emit the files array as nicely indented object entries instead of a single JSON.stringify output to improve readability and avoid extremely long lines
+
+## 2026-01-12 - 2.7.2 - fix(readme)
+update README to add interactive setup (tsbundle init), expand quick start and usage examples, include pnpm install, document embedding/base64ts output with Deno example, add project structure recommendations, and clarify license/trademark wording
+
+- Add interactive setup command: `tsbundle init` and updated Quick Start flow
+- Include pnpm global install instruction in installation section
+- Replace API example with clarified build instructions and new bundle presets (element, website, npm, custom)
+- Document embedded bundle output (base64ts) and Deno usage example for decoding/serving files
+- Add recommended project structure and formatting improvements (emoji/icons, section reorganizations)
+- Clarify license link and expand trademark wording to mention third-party trademarks and approval requirements
+
 ## 2026-01-11 - 2.7.1 - fix(package.json)
 update repository URL to code.foss.global

 # Local installation for project usage
 npm install --save-dev @git.zone/tsbundle
+
+# Or with pnpm
+pnpm add -g @git.zone/tsbundle
 ```
 
-## Quick Start
+## Quick Start ⚡
 
-### CLI Usage
+### Interactive Setup
 
-The simplest way to bundle your project:
+The easiest way to get started is with the interactive wizard:
+
+```bash
+tsbundle init
+```
+
+This will guide you through setting up your bundle configuration with preset options:
+
+- **element** - Web component / element bundle (`./ts_web/index.ts` → `./dist_bundle/bundle.js`)
+- **website** - Full website with HTML and assets (`./ts_web/index.ts` → `./dist_serve/bundle.js`)
+- **npm** - NPM package bundle (`./ts/index.ts` → `./dist_bundle/bundle.js`)
+- **custom** - Configure everything manually
+
+### Build Your Bundles
+
+Once configured, simply run:
 
 ```bash
-# Bundle with default settings (from ./ts_web/index.ts to ./dist_bundle/bundle.js)
 tsbundle
-
-# Bundle with custom paths
-tsbundle --from="./src/index.ts" --to="./dist/bundle.js"
-
-# Production build with minification
-tsbundle --from="./src/index.ts" --to="./dist/bundle.js" --production
-
-# Use a specific bundler
-tsbundle --bundler=rolldown
 ```
 
-### API Usage
-
-```typescript
-import { TsBundle } from '@git.zone/tsbundle';
-
-const bundler = new TsBundle();
-
-// Basic usage
-await bundler.build(
-  process.cwd(), // working directory
-  './src/index.ts', // entry point
-  './dist/bundle.js', // output file
-  { bundler: 'esbuild' }, // options
-);
-
-// Production build with rolldown
-await bundler.build(process.cwd(), './src/index.ts', './dist/bundle.min.js', {
-  bundler: 'rolldown',
-  production: true,
-});
-```
-
-## Available Bundlers
-
-tsbundle supports three modern bundlers, each with its own strengths:
-
-- **esbuild** (default): Extremely fast, great for development
-- **rolldown**: Rust-based bundler with excellent tree-shaking
-- **rspack**: High-performance bundler with webpack compatibility
-
-Select your bundler using the `--bundler` flag in CLI or the `bundler` option in API.
+That's it! Your bundles will be built according to your `npmextra.json` configuration.
 
 ## CLI Commands
 
-### Default Command
+| Command | Description |
+|---------|-------------|
+| `tsbundle` | Build all bundles from `npmextra.json` configuration |
+| `tsbundle custom` | Same as above (explicit) |
+| `tsbundle init` | Interactive wizard to create/update bundle configuration |
 
-Bundle TypeScript/JavaScript projects:
+## Configuration 📝
 
-```bash
-tsbundle [options]
+tsbundle uses `npmextra.json` for configuration. Here's an example:
 
-Options:
-  --from          Source entry point (default: ./ts_web/index.ts)
-  --to            Output bundle path (default: ./dist_bundle/bundle.js)
-  --production    Enable production mode with minification
-  --bundler       Choose bundler: esbuild, rolldown, or rspack
-  --commonjs      Output CommonJS format instead of ESM
-  --skiplibcheck  Skip TypeScript library checking
+```json
+{
+  "@git.zone/tsbundle": {
+    "bundles": [
+      {

+      }
+    ]
+  }
+}
 ```
 
-### Specialized Commands
+### Bundle Configuration Options
 
-#### `tsbundle element`
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `from` | `string` | - | Entry point TypeScript file |
+| `to` | `string` | - | Output file path |
+| `outputMode` | `"bundle"` \| `"base64ts"` | `"bundle"` | Output format (see below) |
+| `bundler` | `"esbuild"` \| `"rolldown"` \| `"rspack"` | `"esbuild"` | Which bundler to use |
+| `production` | `boolean` | `false` | Enable minification |
+| `includeFiles` | `string[]` | `[]` | Glob patterns for additional files (HTML, assets) |
+| `maxLineLength` | `number` | `0` (unlimited) | For `base64ts` mode: max chars per line in output |
 
-Bundle web components with standard naming conventions:
+### Output Modes
 
-```bash
-tsbundle element
-# Bundles from ./ts_web/elements/<elementName>.ts to ./dist_bundle/bundle.js
+#### `bundle` (default)
+Standard JavaScript bundle output. Additional files specified in `includeFiles` are copied to the output directory.
+
+#### `base64ts`
+Generates a TypeScript file with base64-encoded content - perfect for **Deno compile** scenarios where you need everything embedded in a single executable:
+
+```typescript
+// Auto-generated by tsbundle
+export const files: { path: string; contentBase64: string }[] = [
+  { path: "bundle.js", contentBase64: "Y29uc3QgaGVsbG8gPSAid29ybGQi..." },
+  { path: "index.html", contentBase64: "PCFET0NUWVBFIGh0bWw+..." },
+];
 ```
 
-#### `tsbundle npm`
+**Tip:** If you're working with AI tools that have line length limitations, set `maxLineLength` (e.g., `200`) to split long base64 strings across multiple lines.
 
-Bundle npm packages for distribution:
+## Available Bundlers 🔧
 
-```bash
-tsbundle npm
-# Prepares your package for npm publishing
-```
+tsbundle supports three modern bundlers:
 
-#### `tsbundle website`
+| Bundler | Speed | Best For |
+|---------|-------|----------|
+| **esbuild** | ⚡⚡⚡ Blazing fast | Development, quick iterations |
+| **rolldown** | ⚡⚡ Fast | Production builds, tree-shaking |
+| **rspack** | ⚡⚡ Fast | Webpack compatibility |

-## Advanced Examples
+## Complete Example 🎯
 
-### Building a Modern Web Application
+### 1. Initialize your project
 
-```typescript
-import { TsBundle, HtmlHandler, AssetsHandler } from '@git.zone/tsbundle';
-
-async function buildWebApp() {
-  const bundler = new TsBundle();
-  const htmlHandler = new HtmlHandler();
-  const assetsHandler = new AssetsHandler();
-
-  // Bundle the JavaScript
-  await bundler.build(process.cwd(), './src/app.ts', './dist/app.js', {
-    bundler: 'rolldown',
-    production: true,
-  });

-    to: './dist/assets',
-  });
-
-  console.log('Build complete!');
-}
-
-buildWebApp();
+```bash
+tsbundle init
 ```
 
-### Multi-Entry Point Bundling
+Select "website" preset for a full web application setup.
 
-```typescript
-import { TsBundle } from '@git.zone/tsbundle';
-
-async function buildMultipleEntries() {
-  const bundler = new TsBundle();
-  const entries = [
-    { from: './src/main.ts', to: './dist/main.js' },
-    { from: './src/admin.ts', to: './dist/admin.js' },
-    { from: './src/worker.ts', to: './dist/worker.js' },
-  ];
-
-  for (const entry of entries) {
-    await bundler.build(process.cwd(), entry.from, entry.to, {
-      bundler: 'esbuild',
-    });
-  }
-}
-```
-
-### Development vs Production Builds
-
-```typescript
-import { TsBundle } from '@git.zone/tsbundle';
-
-const bundler = new TsBundle();
-const isDev = process.env.NODE_ENV === 'development';
-
-await bundler.build(
-  process.cwd(),
-  './src/index.ts',
-  isDev ? './dist/dev/bundle.js' : './dist/prod/bundle.min.js',
-  {
-    bundler: isDev ? 'esbuild' : 'rolldown', // esbuild for speed in dev
-    production: !isDev, // minify in production
-    commonjs: false, // use ES modules
-  },
-);
-```
-
-## TypeScript Configuration
-
-tsbundle works best with the following TypeScript configuration:
+### 2. Your generated config
 
 ```json
 {
-  "compilerOptions": {
-    "target": "ES2022",
-    "module": "ESNext",
-    "moduleResolution": "node",
-    "esModuleInterop": true,
-    "allowSyntheticDefaultImports": true,
-    "strict": true
+  "@git.zone/tsbundle": {
+    "bundles": [
+      {
+        "from": "./ts_web/index.ts",
+        "to": "./dist_serve/bundle.js",
+        "outputMode": "bundle",
+        "bundler": "esbuild",
+        "includeFiles": ["./html/**/*.html", "./assets/**/*"]
+      }
+    ]
   }
 }
 ```
 
-## Best Practices
+### 3. Create your entry point
 
-1. **Entry Points**: Keep your entry points in `ts_web/` for web bundles or `ts/` for library bundles
-2. **Output Structure**: Use `dist_bundle/` for bundled files and `dist_serve/` for web-ready files
-3. **Bundler Selection**:
-   - Use `esbuild` for development (fastest)
-   - Use `rolldown` or `rspack` for production (better optimization)
-4. **Assets**: Place static assets in the `assets/` directory
-5. **HTML**: Keep HTML templates in the `html/` directory
+```typescript
+// ts_web/index.ts
+console.log('Hello from tsbundle! 🚀');
+
+export const app = {
+  version: '1.0.0',
+  init() {
+    console.log('App initialized');
+  }
+};
+
+app.init();
+```
+
+### 4. Build
+
+```bash
+tsbundle
+```
+
+Your bundle is ready in `./dist_serve/bundle.js` along with any HTML and assets!
+
+## Embedding for Deno Compile 🦕
+
+For single-executable scenarios with Deno:
+
+```bash
+tsbundle init
+# Select "custom", set outputMode to "base64ts"
+```
+
+Config:
+```json
+{
+  "@git.zone/tsbundle": {
+    "bundles": [
+      {
+        "from": "./ts_web/index.ts",
+        "to": "./ts/embedded-bundle.ts",
+        "outputMode": "base64ts",
+        "bundler": "esbuild",
+        "production": true,
+        "includeFiles": ["./html/index.html"],
+        "maxLineLength": 200
+      }
+    ]
+  }
+}
+```
+
+Then in your Deno app:
+```typescript
+import { files } from './ts/embedded-bundle.ts';
+
+// Decode and serve your embedded files
+const bundle = files.find(f => f.path === 'bundle.js');
+const html = files.find(f => f.path === 'html/index.html');
+
+const bundleContent = atob(bundle.contentBase64);
+const htmlContent = atob(html.contentBase64);
+```
+
