# Changelog

> プロジェクトの進捗状況をマークダウンで読むことは、コミットログを読むより簡単です。

コミットメッセージからのChangelog生成は、今はかなり一般的なパターンです。[Convention-changelog](https://github.com/conventional-changelog/conventional-changelog)というプロジェクトがあり、\_convention\_に続くコミットメッセージからChangelogを生成します。

## コミットメッセージの規約

もっとも一般的なのは、[\_angular\_のCommitメッセージ](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#-git-commit-guidelines)の規約です。

## セットアップ

* インストール：

```bash
npm install standard-version -D
```

* あなたの`package.json`に`script`ターゲットを追加してください：

```javascript
{
  "scripts": {
    "release": "standard-version"
  }
}
```

* オプション： 自動的に新しいgit commitとtagをpushして、npmにpublishする`postrelease`スクリプトを追加します:

```javascript
{
  "scripts": {
    "release": "standard-version",
    "postrelease": "git push --follow-tags origin master && npm publish"
  }
}
```

## リリース

単に以下を実行します：

```bash
npm run release
```

バージョンはコミットメッセージ`major`|`minor`|`patch`に基づいて自動的に決定されます。明示的にバージョンを指定したい場合は、`--release-as`を指定することができます：

```bash
npm run release -- --release-as minor
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://typescript-jp.gitbook.io/deep-dive/intro-2/changelog.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
