# 🚀 Create New Branch
✨ **cnb** is a simple and customizable CLI tool that helps you create Git branches following naming conventions, and validates (lints) branch names to ensure they follow the configured conventions.
## 🎬 Demo
## 📦 Installation
Install the package as a dev dependency:
```bash
npm i -D cnb
```
## 🛠️ Usage
### Creating a New Branch
1. Add the following alias to your `.gitconfig`:
```shell
[alias]
cnb = "!npx cnb"
```
2. Add the following script to your `package.json`:
```json
"scripts": {
"prepare": "git config --local include.path ../.gitconfig",
}
```
3. Make sure the prepare script runs before trying the new git alias. You can do this by running (only once):
```bash
npm i
```
Or explicitly run the script:
```bash
npm run prepare
```
4. Run the following command to create a new branch with naming conventions:
```bash
git cnb
```
This will prompt you with a set of options to choose from (e.g., `feat`, `fix`, `chore`, etc.). You'll also provide a short description that will be formatted into kebab-case.
Example:
- Selected type: `feat`
- Description: `configure notifications`
The branch created will be: `feat/configure-notifications`.
If your configuration requires a ticket ID (based on your config file), the flow will prompt you to enter that first.
### Linting a Branch Name
You can also use **cnb** to lint and validate if the current branch name follows your configured conventions.
1. Add the following script to your `package.json`:
```json
"scripts": {
"cnb:check": "cnb --check"
}
```
2. Run the script to lint the current branch name:
```bash
npm run cnb:check
```
## 📁 Configuration
You can customize the behavior of **cnb** by creating a configuration file in your project root called `cnb.config.ts` (for ES6 environments) or `cnb.config.cjs` (for CommonJS environments).
### Configuration Options
| Option | Type | Description | Default |
| ---------------------- | ---------- | ----------------------------------------------------------------------------------------------- | ----------------------------------- |
| `branchTypes` | `string[]` | The types of branches you can select (e.g., `feat`, `fix`, `chore`, `style`) | `['feat', 'fix', 'chore', 'style']` |
| `maxDescriptionLength` | `number` | The maximum length allowed for the branch description. | `20` |
| `skipTicketId` | `boolean` | Whether to skip the ticket ID prompt. | `false` |
| `ticketIdPrefix` | `string` | The prefix to add to the ticket ID (e.g., `JIRA-`). | `T-` |
| `separator` | `string` | The character(s) used to separate the ticket ID, branch type, and branch name (e.g., `/`, `_`). | `/` |
### Example `cnb.config.ts` (ES6)
```ts
import type { CnbConfig } from 'cnb';
const config: CnbConfig = {
branchTypes: ['feat', 'fix', 'chore', 'style'],
maxDescriptionLength: 20,
skipTicketId: false,
ticketIdPrefix: 'JIRA-',
};
export default config;
```
### Example `cnb.config.cjs` (CommonJS)
```js
module.exports = {
branchTypes: ['feat', 'fix', 'chore', 'style'],
maxDescriptionLength: 20,
skipTicketId: false,
ticketIdPrefix: 'JIRA-',
};
```
## 🛠️ Note for ES6 vs. CommonJS Users
- **For ES6 users**: Create your configuration file as `cnb.config.ts` and use `export default`.
- **For CommonJS users**: Create your configuration file as `cnb.config.cjs` and use `module.exports`.
