# @git.zone/tsbuild

A flexible TypeScript compiler that leverages the latest TypeScript features to streamline your build process.

## Install

Add `@git.zone/tsbuild` to your project using npm or yarn:

```bash
npm install @git.zone/tsbuild
```

or

```bash
yarn add @git.zone/tsbuild
```

## Key Features

- Utilize the latest TypeScript features
- Flexible API for customized compilation processes
- Intuitive CLI for common build tasks
- Support for glob patterns to easily target files
- Ordered compilation to respect module dependencies

## API Reference

### Core Compilation Functions

#### `compileFileArray(fileStringArrayArg: string[], compilerOptionsArg?: CompilerOptions, argvArg?: any): Promise<any[]>`

Compiles an array of TypeScript files with customizable compiler options.

```typescript
import { compileFileArray } from '@git.zone/tsbuild';

const files = [
  './src/file1.ts',
  './src/file2.ts',
];
const options = {
  target: "ES2020",
  module: "CommonJS"
};

compileFileArray(files, options)
  .then(compiledFiles => {
    console.log('Compiled Files:', compiledFiles);
  })
  .catch(error => {
    console.error('Compilation Error:', error);
  });
```

#### `compileGlobStringObject(globStringObjectArg: Record<string, string>, tsOptionsArg?: CompilerOptions, cwdArg?: string, argvArg?: any): Promise<any[]>`

Compiles files matching glob patterns to specified output directories.

```typescript
import { compileGlobStringObject } from '@git.zone/tsbuild';

const globPattern = {
  './src/**/*.ts': './dist',
};
const compilerOptions = {
  target: "ESNext",
  module: "ESNext",
};

compileGlobStringObject(globPattern, compilerOptions)
  .then(compiledFiles => {
    console.log('Compilation complete:', compiledFiles);
  })
  .catch(error => {
    console.error('Error during compilation:', error);
  });
```

## Command Line Interface

The CLI provides convenient commands for common compilation tasks.

### Standard Command

Compiles all TypeScript files in the `ts/` directory to the `dist_ts` directory:

```bash
npx tsbuild
```

### Custom Command

Compile specific directories to corresponding `dist_` directories:

```bash
npx tsbuild custom <Dir1> <Dir2> ...
```

Example: `npx tsbuild custom src utils` compiles:
- `./src/**/*.ts` → `./dist_src`
- `./utils/**/*.ts` → `./dist_utils`

### TSFolders Command

Compiles TypeScript folders in a specific order based on dependencies:

```bash
npx tsbuild tsfolders
```

This command:
1. Identifies all folders starting with `ts` in the current directory
2. Prioritizes `ts_interfaces` and `ts_shared` to be compiled first
3. Orders other folders based on the `order` property in their `tspublish.json` files (if available)
4. Compiles each folder to its corresponding `dist_` folder

Example compilation order output:
```
compiling in this order:
[ 'ts_interfaces', 'ts_shared', 'ts_core', 'ts_utils', 'ts_modules' ]
```

## Compiler Options

Additional flags can be passed to any command to modify the compilation behavior:

- `--skiplibcheck`: Skip type checking of declaration files (shows warning)
- `--allowimplicitany`: Allow variables to be implicitly typed as `any`
- `--commonjs`: Use CommonJS module format instead of ESNext

Example:
```bash
npx tsbuild --skiplibcheck --allowimplicitany
```

## Default Compiler Options

By default, `@git.zone/tsbuild` uses the following compiler options:

```typescript
{
  declaration: true,
  emitDecoratorMetadata: true,
  experimentalDecorators: true,
  inlineSourceMap: true,
  noEmitOnError: true,
  outDir: 'dist_ts/',
  module: ModuleKind.NodeNext,
  target: ScriptTarget.ESNext,
  moduleResolution: ModuleResolutionKind.NodeNext,
  lib: ['lib.dom.d.ts', 'lib.es2022.d.ts'],
  noImplicitAny: true,
  esModuleInterop: true,
  useDefineForClassFields: false,
  verbatimModuleSyntax: true,
  baseUrl: './',
}
```

These options can be overridden by providing a custom `CompilerOptions` object.

## Path Resolution

The package automatically detects and applies path mappings from your `tsconfig.json`. When it finds path mappings, it adjusts them to work with the compiled output by replacing `./ts_` with `./dist_ts_` in path aliases.

## Notes and Best Practices

- Each glob pattern compilation runs in its own pass, which may cause duplicate error messages if shared files are included in multiple patterns
- Use the `--skiplibcheck` option cautiously as it will pause for 5 seconds with a warning before continuing
- If you need different output configurations for different file sets, use multiple calls to `compileGlobStringObject`
