MatchaBot

Introduction

MatchaBot is a code generator written in TypeScript.

You can use matchabot to create an entire project, or to generate code inside an existing project in a consistent way.

This tool has been created to offer a "Ruby on Rail" like programming experience with any projects: React / Vue / Angular, NextJS / Gatsby, etc ...

The complete documentation of the project is available at https://www.matchabot.site/

Features

• ✅ Easy to use in project generator
• ✅ You can create your own generator by project, or use a global templates repository
• ✅ Templating language support: HandleBars and EJS
• ✅ Powerful command line support: automatic CLI arguments and automatic prompts for missing arguments
• ✅ Simplified workflow to create new generators for you own project
• ✅ Debug mode
• ✅ Add new file to your project
• ✅ Modify existing files
• ✅ You can generate any kind of files/projects (NodeJS, typescript, Javascript, SQL, C++, C, Go, ...)

Benefits

• ✅ Simple and Powerful
• ✅ Save time and Boost your productivity
• ✅ Enforce a consistent project structure
• ✅ Easier team onboarding with a codified best practices stored inside each project
• ✅ Fun to use 🦄

Key concepts

• 👉 A code generator is identified by a name
• 👉 A code generator offer one or more commands
• 👉 A command takes a list of arguments as input and execute a list of actions ⚙️.
• 👉 ️️A generator action is specified by one or multiple template written with a templating language such as HandleBars or EJS
• 👉 The generators definition are stored inside your project inside the ./_machatbot directory as a subdirectory
• 👉 commands are defined by a matchabot.cmd.json file inside the ./_machatbot/--generator-name-- directory

👉 How to start

1 - Add matchabot to your project

Execute the following command at the root of your project.

yarn add matchabot --dev

or

npm install matchabot --save-dev

💡 matchabot can be installed globally with

npm install -g matchabot

2️ - Initialise matchabot

Execute the following command at the root of your project.

matchabot init

👉 This command create a local directory ./_matchabot inside your current project directory

In this example, the _matchabot is composed of 2 generators

• license
• react-app

Each generator is defined by a matchabot.jsonfile

Example for license

{
  "name": "license",
  "description": "📃 Add licence to your project",
  "version": "1.0.0"
}

Each subdirectory contains a definition of a command associated with a generator

For the react-appgenerator we have 2 commands:

• create-app
• create-component

Each subdirectory contains a matchabot.cmd.json file that defines the commands and list of actions to perform.

Example ./_matchabot/license/add/matchabot.cmd.json:

{
  "name": "add",
  "description": "add a licence file to your project",
  "version": "1.0.0",
  "args": [
    {
      "name": "CopyRightsHolder",
      "alias": "c",
      "type": "string",
      "default": "{{process.env.LOGNAME}}"
    },
    {
      "name": "ProgramDescription",
      "alias": "p",
      "type": "string"
    },
    {
      "name": "LicenceType",

      "type": "list",
      "choices": [
        { "name": "MIT License", "value": "mit" },
        { "name": "BSD License", "value": "bsd" },
        { "name": "Apache License, Version 2.0", "value": "apache2" },
        { "name": "GNU General Public License version 3", "value": "gnu3" }
      ],
      "default": "MIT"
    }
  ],
  "actions": [
    {
      "type": "template",
      "name": "Generate Licence",
      "source": "{{toLowerCase LicenceType}}.md.hbs",
      "target": "LICENCE.md"
    }
  ]
}

command arguments

In this example, the args array contains a list of arguments (variables) that will be used in the templates.

command actions

In this example with only have 1 action: select a template from "source": "{{toLowerCase LicenceType}}.md.hbs" and generates a file "target": "LICENCE.md"

3 - List all available generators
