kickstart

Kick start a project by generating code according to template. Defined a template project and reuse it again and again to kick start new projects. All kinds of projects are supported no matter what programming languages they use.

It's a much simpler alternative to Yeoman.

Install

yarn global add kickstart-cli

Usage

ks -k kickstart-project -o output-directory

A new project will be created at output-directory, using kickstart-project as template.

-o output-directory is optional. By default it is ., a.k.a. the current directory.

Features

• Support projects in all programming languages.
• Support any project to be used as template, even they are not created for scaffolding purpose.
• Support templating, thanks to nunjucks.

Why?

Lots of projects look similar. For example, when I start a new JavaScript projects, I always created the following files: README.md, package.json, .gitignore, .editorconfig, .babelrc...etc.

I wanted a command line utility to create those files for me. I checked the popular Yeoman project but failed to comprehend its authoring workflow. I decided to create a new tool which is both flexible and straightforward.

Q & A

• Is kickstart for JavaScript projects only?
  • Nope, it is for all kinds of projects no matter what programming languages they use.
• Does kickstart support template projects with nested directory structure?
  • Yes. Template project can have deeply nested directory strucutre.
• What's the main differences between Yeoman and kickstart?
  • A template project for Yeoman (they call it a generator project) must be a Node.js module. Kickstart doesn't have this requirement.
    • Yeoman could generate projects for all kinds of languages but the template/generator project must be Node based. So developers who don't write JavaScript might have difficulty authoring a template/generator project.
  • Kickstart is much simpler than Yeoman. On the other hand, it doesn't have as many features as Yeoman. Kickstart is pretty new and it is still under development.
• Why is kickstart better than cp -r source-project target-directory ?
  • kickstart won't copy .git/
  • kickstart won't copy files/directories specified in .gitignore
  • kickstart supports configuration and templating.

How it works

First of all, ask yourself: do I or my users create similar projects again and again? If the answer is no, you probably don't need kickstart and you can stop reading on.

If the answer is yes, create a template project for those similar projects to abstract the things that they have in common. For strings that each project might have a different value, define them as {{ variable }}.

For example, I can define a template for JavaScript projects with the following directory structure:

kickstart-javascript
    - README.md
    - package.json
    - .gitignore
    - kickstart.yml

Please note that, a template project usually has a kickstart.yml file in its root directory. If no kickstart.yml file is found, an empty one will be used instead. Thus allows any project to be used as a template project.

A sample package.json file:

{
  "name": "{{ name }}",
  "version": "{{ version }}",
  "license": "{{ license }}",
}

A sample kickstart.yml file:

name: my-app
version: 0.1.0
license: MIT

Run the following command to generate a new project:

mkdir my-awesome-project && cd my-awesome-project
ks -k /path/to/kickstart-javascript/

The generated project:

my-awesome-project
    - README.md
    - package.json
    - .gitignore

Generated package.json file has the following content:

{
  "name": "my-app",
  "version": "0.1.0",
  "license": "MIT",
}

You can also edit the kickstart.yml file as below before executing the ks command:

name: cool-project
version: 0.2.0
license: MIT

In such case the generated package.json file is:

{
  "name": "cool-project",
  "version": "0.2.0",
  "license": "MIT",
}

Advanced templating

Nunjucks is the underlying templating engine.

You can use some of its adanvaced features. Sample:

kickstart.yml:

food:
  ketchup: 5 tbsp
  mustard: 1 tbsp
  pickle: 0 tbsp

Template:

{% for ingredient, amount in food %}
  Use {{ amount }} of {{ ingredient }}
{% endfor %}

Templating in directory/file name

You can use templating in directory/file name.

For example:

src/{{ serviceName }}/handler.js

Comments

You can write comments as {# comments #} which will be omitted when generating code.

Todo

• Each template project must be a runnable project itself
• Toml + regex as config file
  • Just use string match, no regex
  • Then how to support if, for...etc?
    • Can we give up these adavanced templating features?
      • Then no more nunjucks
