## polkadot-dev-run-node-ts

**Summary**:  
This script executes a Node.js script with TypeScript support, using the `@polkadot/dev-ts/cached` loader by default. It dynamically handles global and local loaders and allows for additional Node.js flags to be passed.

### CLI Arguments

- `<script>`: The TypeScript file to execute.
- `[args...]`: Arguments to pass to the executed script.
- Node.js flags, such as `--require`, `--loader`, and `--import`, are also supported and processed as follows:
  - **Global loaders** (e.g., absolute or non-relative paths) are prioritized.
  - The TypeScript loader is inserted after global loaders.
  - **Local loaders** (e.g., relative paths starting with `.`) are appended last.

### Default Behavior

- Suppresses warnings using the `--no-warnings` flag.
- Enables source maps with `--enable-source-maps`.
- Uses the `@polkadot/dev-ts/cached` loader for TypeScript execution.

### Usage

```bash
yarn polkadot-dev-run-node-ts <script> [nodeFlags...] [args...]
```

Notes:

- The execNodeTs function ensures correct ordering of loaders:
1. Global loaders are added first.
2. The default TypeScript loader is included.
3. Local loaders are appended.
- Global and local loaders can be mixed for flexible runtime configurations.

## polkadot-dev-run-test

  Imports the specified module.

- **`--loader <loader>`**:  
  Specifies a custom Node.js loader.

- **`--require <module>`**:  
  Preloads the specified module.

- **Filters**:  
  You can include or exclude specific test files by specifying path-based filters:  
  - Include: `filter` (e.g., `utils`)  
  - Exclude: `^filter` (e.g., `^utils`)  

### Supported Test Files

The script searches for test files with the following extensions:  
- **File Types**: `.spec`, `.test`  
- **Languages**: `.ts`, `.tsx`, `.js`, `.jsx`, `.cjs`, `.mjs`  

### Usage

```bash
yarn polkadot-dev-run-test [options] [filters...]
```

### Behavior

- **Filters:**
Filters are applied to include or exclude test files based on their paths. Included filters take precedence, and excluded filters are applied afterward.

- **Execution:**
The script dynamically loads the appropriate environment setup (node or browser) and runs the tests using @polkadot/dev-test.

- **Errors:**
If no matching files are found, the script exits with a fatal error.

- **Development Mode:**
In development mode, local build paths are used for test and TypeScript loaders.

## polkadot-dev-version

**Summary**:  
This script automates the version bump process for a package or a monorepo. It updates the `version` field in `package.json` files and synchronizes dependency versions across workspaces. It supports major, minor, patch, and pre-release version bumps.

### CLI Arguments

- `<type>`: The type of version bump to apply.
  - Acceptable values: `major`, `minor`, `patch`, `pre`
  - Required.

### Behavior

1. **Version Bump**:
   - Uses `yarn version` to bump the root package version based on the specified `<type>`.

2. **Synchronizes Dependencies**:
   - Updates all `dependencies`, `devDependencies`, `peerDependencies`, `optionalDependencies`, and `resolutions` across all workspace packages to match the new version where applicable.

3. **Handles `-x` Suffix**:
   - If the root package's version ends with `-x`, it is temporarily removed before the version bump and re-added afterward for pre-releases.

4. **Updates Workspaces**:
   - Loops through all `packages/*` directories to update their `package.json` files with the new version and aligned dependencies.

5. **Installs Updated Dependencies**:
   - Runs `yarn install` to apply dependency updates after bumping versions.

### Usage

```bash
yarn polkadot-dev-version <type>
```

## polkadot-dev-yarn-only
