start-ts-by

Create ts/js projects from flexible templates using git and local folders.

---

🚀 Get Started

npx start-ts-by [projectName]
# or
npx start-ts-by create [projectName]

Interactive Mode

npx start-ts-by
# Example workflow:
# 🚀 Start creating project...
# ✔ Enter project name: my-app
# ✔ Enter template (e.g. user/repo, ./local-path, git@domain:group/repo.git)
# ? Choose a template (Use arrow keys)
#   royfw/starter-ts-app (Starter TypeScript App)
#   royfw/starter-ts-lib (Starter TypeScript Library)
#   ...

Non-interactive Mode

Basic Usage

# Using --no-interaction (--ni) flag
npx start-ts-by my-app -t royfw/starter-ts-app --no-interaction
npx start-ts-by my-app -t royfw/starter-ts-app --ni

# Legacy --skip-prompt flag (deprecated, use --no-interaction)
npx start-ts-by my-app --skip-prompt -t royfw/starter-ts-app

Monorepo Mode

# Non-interactive mode: Remove lock files, workspace config, .npmrc, and packageManager field
npx start-ts-by my-app -t user/repo --monorepo --ni

# Combine with other flags
npx start-ts-by my-app -t user/repo --monorepo --no-husky --ni

# Interactive mode: Specify --monorepo flag upfront
npx start-ts-by my-app -t user/repo --monorepo

# Interactive mode: Will prompt for monorepo mode if not specified
npx start-ts-by my-app -t user/repo
# During prompts, you'll see:
# ? Enable monorepo mode? (Remove lock files, workspace config, .npmrc, and packageManager field) (y/N)

The --monorepo flag (or interactive prompt) automatically removes files that conflict with monorepo root configuration:

• pnpm-lock.yaml, pnpm-workspace.yaml, package-lock.json, yarn.lock (lock files and workspace config)
• .npmrc (package manager config)
• .husky directory and prepare script containing "husky" in package.json
• .github directory (GitHub Actions workflows)
• packageManager field in package.json

Interactive Mode Behavior:

• If you provide --monorepo flag when starting, it will be pre-selected in the prompts
• If you don't provide the flag, you'll be asked during the interactive prompts
• Default is false (not enabled) - press Enter to skip or type 'y' to enable

This is useful when creating subprojects in a monorepo where these files should be managed at the root level.

Advanced Non-interactive with Variables

# Using --vars for inline variables
npx start-ts-by my-app --ni --vars name=my-app,template=user/repo
npx start-ts-by my-app --ni --vars "removeList[0].field=README.md,removeList[0].isRemove=true"

# Using --vars-file for configuration files
npx start-ts-by my-app --ni --vars-file ./project.vars

# Combining multiple sources (vars override vars-file)
npx start-ts-by my-app --ni --vars-file ./base.vars --vars template=user/custom-repo

Variable File Format (.vars)

Create a .vars file with key=value pairs:

# project.vars
name=my-awesome-app
template=user/repo

# Nested variables for removeList
removeList[0].field=README.md
removeList[0].isRemove=true
removeList[1].field=.github
removeList[1].isRemove=false

# Execution options
execList[0].key=gitInit
execList[0].command=git init
execList[0].isExec=true

# File content (@ prefix reads from file)
# token=@./secret-token.txt

# Include other vars files
# include: ./common.vars

Template Sources with Branches/Subdirectories

npx start-ts-by my-app -t royfw/starter-ts-app#dev/subdir --ni
npx start-ts-by my-app -t git@your.gitlab:group/repo.git#v2/templates --ni
npx start-ts-by my-app -t ./my-template-folder/subdir --ni

List Available Templates

# List all available templates (human-readable format)
npx start-ts-by --list
npx start-ts-by -l

# List templates in JSON format (for programmatic use)
npx start-ts-by --list-json

# List templates with descriptions (verbose mode)
npx start-ts-by --list-verbose

Example Output:

📦 Available Templates:

📌 Built-in Templates (builtin)
  ├─ TypeScript Library
  ├─ TypeScript Application
  └─ Monorepo Template

🌐 start-ts-templates (registry)
  ├─ App (tsdown)
  └─ Library

✨ Total 5 templates from 2 sources

🌐 Registry Support

start-ts-by supports loading templates from external registries, allowing you to use community-provided template collections.

Setting Up Registry

Create a registry-config.json file:

{
  "registries": [
    {
      "name": "start-ts-templates",
      "url": "https://raw.githubusercontent.com/royfw/start-ts-templates/main/registry.json",
      "enabled": true
    }
  ],
  "cacheDir": ".cache/registries",
  "cacheTTL": 3600000
}

Registry.json Format

External registries should provide a JSON file in the following format:

{
  "repo": "your-org/your-templates-repo",
  "defaultRef": "main",
  "templates": [
    {
      "id": "template-id",
      "path": "templates/template-path",
      "title": "Template Display Name",
      "description": "Optional description"
    }
  ]
}

Using Registry Templates

When running npx start-ts-by create my-project:

1. Select template source (Built-in / Registry / Manual input)
2. If you choose Registry, select a specific template
3. Or use --list to view all available templates

For detailed instructions, see Registry Guide | zh-TW.

Official Template Collection

  --vars <pairs...>                 Variables in key=value format (can be used multiple times)
  --vars-file <path>                Path to variables file (non-JSON, supports includes)
  --strict                          Strict mode: treat duplicate keys and type conflicts as errors
  --rm <files...>                   Remove files/folders after project creation
  --no-husky                        Remove .husky
  --github                          Keep .github/workflows

Variable Priority (high to low)

1. --vars command line arguments
2. --vars-file file contents
3. Individual flags (-t, --rm, etc.)
4. Environment variables
5. Interactive input
6. Default values

Error Handling

• Non-interactive mode requires name and template parameters
• Missing required parameters exit with code 2
• File read errors and parsing failures provide specific error messages
• --strict mode treats duplicate keys and type conflicts as errors (default: warnings)

Key changes:

• degit is removed, all template fetching is handled by git commands or direct file copy.
• Template source string is parsed to support repo URLs, branches, tags, and subdirectories.
