Saber-cli

Saber-cli is a project scaffold management tool used to scaffold your project based on specific template sources. The default registry is saber-cli-templates. And you can switch to your personal template registry source.That's really awesome!

Install

# install saber-cli
yarn global add @zenghj/saber-cli

Create a Project

# create a new project based on specific template
saber init templateName projectName

Usage

Usage: saber [options] [command]
# saber-dev [options] [command] (print some logs for dev)

Options:
  -V, --version  output the version number
  -c, --clone    use git clone
  -p, --private  directly git clone from private repository, make sure you have access to the repository
  -h, --help     output usage information

Commands:
  init|i         generate a new project
  config|cfg     config .saberrc

Usage:
  - saber init templateName projectName     create a project from a template
  - saber config set <k> <v>                set config
  - saber config set registry $registryUri  set a template registry
  - saber config get <k>                    get config[k]
  - saber config get                        get total config
  - saber config reset                      reset total config
  - saber config select-registry            select registry from config.registries
  - saber config sr                         abbreviation of "saber config select-registry"

You can use saber config set registry {registrySource} to change templates' downloading source. Then it will get template from ${registrySource}/${templateName}

Download template from private gitlab

If you don't want to put your template on public git platform like github, you can set the private registry source first and then use saber init -p ${templateName} ${projectName}. It will directly execute shell script to clone the repository from the private registry. But make sure you have access to the private repository.

Supported templates

comming soon...

Develop template

The template repository should have files like below:

├── README.md // template description
├── meta.json // config custom field here
└── template // project template files
    └── anything you like!

meta.json

meta.json is where you define some magic things, which looks like this:

{
  "prompts": {
    "name": {
      "type": "string",
      "required": true,
      "label": "Project name"
    },
    "description": {
      "type": "string",
      "required": true,
      "label": "Project description",
      "default": "A demo project"
    },
    "author": {
      "type": "string",
      "label": "Author"
    },
    "license": {
      "type": "string",
      "label": "License",
      "default": "MIT",
      "validate": "function(answer) {var licenses = ['LGPL', 'MIT', 'GPL']; if (!licenses.includes(answer)) {return `License should be one of ${licenses}`} return true}"
    },
    "test_checkbox": {
      "type": "checkbox",
      "label": "test_checkbox",
      "choices": [
        {
          "value": "A",
          "name": "A"
        },
        {
          "checked": true,
          "value": "B",
          "name": "B"
        }
      ]
    },
    "include_filters_dir": {
      "type": "confirm",
      "label": "test_confirm"
    }
  },
  "skipInterpolation": [
    "skip/**"
  ],
  "filters": {
    "filters/**": "data.include_filters_dir === true"
  },
  "completeMessage": "To get started:\n\n  cd {{destDirName}}\n  npm install\n  npm run dev"
}

The meta option interface:

type MetaOption = {
  prompts?: MetaPrompts;// prompts to show when initializing the project
  filters?: MetaFilters; // include some files only when satisfy some condition
  skipInterpolation?: string|string[]; // files not render with meta data,just simply copy
  completeMessage?: string; // displaying message when completing (when `complete` is not defined)
  complete?: (metadata: Object) => any; // callback function when completing
}
prompts

use prompts field to define everything you need to know when initial the template. the prompt interface looks like below:

type MetaPrompt = {
  type: string; // prompt type, see https://www.npmjs.com/package/inquirer
  message?: string; // tips message
  label?: string; // tips message, same as `message`
  required?: boolean; // whether be required or not
  default?: any; // default value
  when?: string; // if `when` expression value is true, then this prompt will show
  choices?: any[]; // needed when type is like 'list', 'checkbox' and so on
  validate?: string | ((...args: any[]) => boolean|string); // validate the input value
}

filters

filters interface:

type MetaFilters = {
  // propName is fileblob tell whether the file will be detect or not
  // the value is an expression return a boolean,
  // if it is false, then the file will be not be generated in the final project.
  // filename blob pattern see https://www.npmjs.com/package/minimatch
  [propName: string]: string // filenameBlob: conditionExpression
}

skipInterpolation

skipInterpolation tell the files which will be skiped during rendering files with handlebarsjs. See multimatch for match patterns.

Render template

We use handlebarsjs to render template content with meta data. So learn the handlebarsjs template syntax at first.
