For more introduction, please refer to the How it works.

Features

• Easy to use
• Light-weight
• Still powerful
• High efficiency
• Zero dependencies
• Template-based
• Configurable
• Extensible
• TypeScript
• Use modern API

I'll give you specific reasons later.

Getting Started

Prerequisites

• Node.js (>= 16.x required, >= 18.x preferred)
• npm (>= 7.x) or pnpm (>= 6.x) or yarn (>= 1.22)
• Git (>= 2.0)

Installation

# install it globally
$ npm install -g caz

# or yarn
$ yarn global add caz

Quick Start

Create new project from a template.

$ caz <template> [project] [-f|--force] [-o|--offline]

# caz with an official template
$ caz <template> [project]

# caz with a github repo
$ caz <owner>/<repo> [project]

If you only use it occasionally, I recommend that you use npx to run caz directly.

$ npx caz <template> [project] [-f|--force] [-o|--offline]

Options

• -f, --force: Overwrite if the target exists
• -o, --offline: Try to use an offline template

Recipes

GitHub Repo Templates

$ caz nm my-project

The above command pulls the template from caz-templates/nm, then prompts for some information according to the configuration of this template, and generate the project at ./my-project.

$ caz nm#typescript my-project

By running this command, CAZ will pulls the template from typescript branch of caz-templates/nm.

Use Custom templates

$ caz zce/nm my-project

The above command pulls the template from zce/nm. This means that you can also pull templates from your public GitHub repository.

Public repository is necessary.

Local Templates

Instead of a GitHub repo, you can also use a template on your local file system.

e.g.

$ caz ~/local/template my-project

The above command use the template from ~/local/template.

Remote ZIP Templates

Instead of a GitHub repo, you can also use a template with a zip file uri.

e.g.

$ caz https://cdn.zce.me/boilerplate.zip my-project

The above command will download & extract template from https://cdn.zce.me/boilerplate.zip.

Offline Mode

$ caz nm my-project --offline

By running this command, CAZ will try to find a cached version of nm template or download from GitHub if it's not yet cached.

Prompts Override

CAZ allows you to specify prompt response answers through cli parameters.

$ caz minima my-project --name my-proj

By running this command, you don't have to answer the next name prompts.

Debug Mode

$ caz nm my-project --debug

--debug parameter will open the debug mode.

In debug mode, once an exception occurs, the exception details will be automatically output. This is very helpful in finding errors in the template.

List Available Templates

Show all available templates:

$ caz list [owner] [-j|--json] [-s|--short]

Arguments

• [owner]: GitHub orgs or user slug, default: 'caz-templates'

Options

• -j, --json: Output with json format
• -s, --short: Output with short format

Official Templates

Current available templates list:

• template - for creating caz templates.
• nm - for creating node modules.
• vercel - for creating vercel apps.
• react - for creating modern react apps.
• vue - for creating modern vue.js apps.
• vite - for creating vue.js apps powered by vite.
• electron - :construction: for creating electron apps.
• mp - :construction: for creating wechat mini-programs.
• jekyll - :construction: for creating jekyll site.
• x-pages - for creating x-pages static site.

Maybe more: https://github.com/caz-templates

You can also run $ caz list to see all available official templates in real time.

All templates are currently hosted on GitHub, Chinese users can use the mirror on coding.net.

Advanced

Configuration

CAZ will read the configuration file in ~/.cazrc, default config:

; template download registry
; {owner} & {name} & {branch} will eventually be replaced by the corresponding value.
registry = https://github.com/{owner}/{name}/archive/{branch}.zip
; template offlicial organization name
official = caz-templates
; default template branch name
branch = master

This means that you can customize the configuration by modifying the configuration file.

For example, in your ~/.cazrc:

registry = https://gitlab.com/{owner}/{name}/archive/{branch}.zip
official = faker
branch = main

Then run the following command:

$ caz nm my-project

The above command will download & extract template from https://gitlab.com/faker/nm/archive/main.zip.

Mirror for Chinese

Due to network limitations, the template download may time out, you can consider using the mirror repository I configured on coding.net.

~/.cazrc:

registry = https://zce.coding.net/p/{owner}/d/{name}/git/archive/{branch}
official = caz

Socks Proxy

CAZ supports socks proxy config.

~/.cazrc:

proxy = socks5://127.0.0.1:1080

or environment variable:

$ ALL_PROXY=socks5://127.0.0.1:1080 caz nm my-project

Create Your Template

$ caz template my-template

The above command will pulls the template from caz-templates/template, and help you create your own CAZ template.

To create and distribute your own template, please refer to the How to create template.

Maybe fork an official template is also a good decision.

Create Your Scaffold

# install it locally
$ npm install caz

# or yarn
$ yarn add caz

with ESM and async/await:

import caz from 'caz'

try {
  const template = 'nm'
  // project path (relative cwd or full path)
  const project = 'my-project'
  const options = { force: false, offline: false }
  // scaffolding by caz...
  await caz(template, project, options)
  // success created my-project by nm template
} catch (e) {
  // error handling
  console.error(e)
}

or with CommonJS and Promise:

const { default: caz } = require('caz')

const template = 'nm'
// project path (relative cwd or full path)
const project = 'my-project'
const options = { force: false, offline: false }
// scaffolding by caz...
caz(template, project, options)
  .then(() => {
    // success created my-project by nm template
  })
  .catch(e => {
    // error handling
    console.error(e)
  })

This means that you can develop your own scaffolding module based on it.

To create and distribute your own scaffolding tools, please refer to the How to create scaffolding tools based on CAZ.

Motivation

👉 🛠 ⚙

Joking: I want to make wheels ;P

The real reason is that I think I need a scaffolding tool that is more suitable for my personal productivity. The existing tools have more or less certain limitations because of their different starting points.

Nothing else.

Concepts

How It Works

P.S. The picture is from the Internet, but I have forgotten the specific source, sorry to the author.

Main Workflow

The core code is based on the middleware mechanism provided by zce/mwa.

The following middleware will be executed sequentially.

1. confirm - Confirm destination by prompts.
2. resolve - Resolve template from remote or local filesystem.
3. load - Install template dependencies, load template config by require.
4. inquire - Inquire template prompts by prompts.
5. setup - Only apply template setup hook function.
6. prepare - Filter out unnecessary files and prepare all files to be generated.
7. rename - Rename each file if the filename contains interpolations.
8. render - Render the contents of each file if template.
9. emit - Emit files to destination.
10. install - Execute npm | yarn | pnpm install command if necessary.
11. init - Execute git init && git add && git commit command if necessary.
12. complete - Only apply template complete hook function.

Roadmap

The following are the features I want to achieve or are under development:

• config command
• cache command
• all lifecycle hooks
• console output (colorful & verbose)
• more and more official templates

See the open issues for a list of proposed features (and known issues).
