What is cz-git?

What is commitizen: A Node.js-based git commit command-line tool that assists in generating standardized and standardized commit messages.

What is an adapter: Replace the interactive plugin for the commitizen command line tool.

Why do it

For the past year, I have been committing almost every day, and as a lazy software engineer, I realized that almost all commitizen adapters are not very comfortable for me to use.

For example, if I repaired the table in the monorepo ui library, I must subconsciously fix the table. Why do I need to keep selecting up and down? I just want fi to press Enter to output fix, ta to press Enter to output table.So much so that I made the cz-git adapter.

Let me introduce the use of cz-git

scopes

scopes, usually to define the scope of this commit, there are generally two types: according to the project code distinction such as monorepo , the other is project business distinction

scopes for project code

If you need to manage multiple packages for a better experience, for example, use: pnpm | lerna.js to manage monorepo you can Use the path and fs modules to dynamically define the scopes (scopes) display in the commit message.

// .commitlintrc.js 
const fs = require('fs')
const path = require('path')
const packages = fs.readdirSync(path.resolve(__dirname, 'packages'))
module.exports = {
  prompt: { 
    scopes: [...packages] 
  }
}

If you define a scope-enum using the commitlintopen in new window rule, it will be imported automatically.

// .commitlintrc.js 
const fs = require('fs')
const path = require('path')
const packages = fs.readdirSync(path.resolve(__dirname, 'packages'))
module.exports = {
  rules: {
    "scope-enum": [2, "always", [ ...packages ]]
  }
};

scopes for business system

// .commitlintrc.js 
const fs = require('fs')
const path = require('path')
const packages = fs.readdirSync(path.resolve(__dirname, 'packages'))
module.exports = {
  prompt: {
    scopes: ["app", "home", "account", "comment"] 
  }
}

Of course, if you want to add description information to the module-wide customization to display on the command line, you can use name and value to define.

// .commitlintrc.js 
const fs = require('fs')
const path = require('path')
const packages = fs.readdirSync(path.resolve(__dirname, 'packages'))
module.exports = {
  prompt: {
    scopes: [
      { value: "app",     name: "app:       System business" },
      { value: "home",    name: "home:      Homepage" },
      { value: "account", name: "account:   Account related" },
      { value: "comment", name: "comment:   Comment related" },
    ]
  }
}

default

defaultIssues

Obtaining the Issue Number automatically, it is a very troublesome thing to repeat the query to fill in the issue number.
- But if the team's branch command rules are standardized (e.g: fix/33)
- Then we use Node's execSync to get the branch name through the command
- Then process the obtained string
- Then we use defaultIssues
- When using, we only need to press the <Enter> key to output the Issue Number, so that we can easily intercept the Issue Number to reduce repetitive work.

// .commitlintrc.js 
const { execSync } = require('child_process');

// @tip: git branch name = feature/33   =>    auto get defaultIssues = #33
 const issue = execSync('git rev-parse --abbrev-ref HEAD')
  .toString()
  .trim()
  .split("/")[1]
// @tip: monorepo dynamic get name

/** @type {import('cz-git').UserConfig} */
module.exports = {
  prompt: {
    defaultIssues: () => !issue ? "" : `#${issue}`
  }
};
