!!!16.0.0開始這個方式不能使用有找到新的方法再重新寫教學

大部分家庭應該都有拜拜的習慣
找了很久都沒有關於在NodeRed中使用國曆農曆轉換的方法
花了一些時間跟ChatGPT來回請益終於搞定
以下分享如何在NodeRed中使用 lunar-calendar-zh 套件
做出國曆農曆轉換的方法

事前工作

  1. 安裝 SSH & Web Terminal 如果已經安裝 Terminal & SSH 請先移除再安裝

    關掉保護模式

  2. 安裝lunar-calendar-zh套件
    打開 SSH & Web Terminal 輸入以下指令

docker exec -it homeassistant /bin/bash
npm install lunar-calendar-zh

此時會發現我們無法用 npm 安裝套件,因為Home Assistant 的操作系統是基於 Alpine Linux 精簡版的
所以我們需要使用 apk 安裝 npm, 照以下方式輸入指令

apk update
apk add nodejs npm

這裡使用 apk 命令來更新套件庫，並安裝 Node.js 和 npm.

更新套件及安裝完後就可以再次透過 npm 安裝 lunar-calendar-zh 套件

接著輸入exit離開docker

  1. 修改NodeRed settings.js 在 functionGlobalContext 局範圍中引入 lunar-calendar-zh 套件
functionGlobalContext: {
    LunarCalendar: require('lunar-calendar-zh')
}

加好存檔離開並重新啟動NodeRed

  1. 再來就可以在NodeRed裡面調用 LunaCalendar了
    下面為function範例,可以依照個人需求去調整
const today = new Date();
const LunarCalendar = global.get('LunarCalendar');
const date = today.toISOString().split('T')[0];
const lunarDate = LunarCalendar.solarToLunar(today.getFullYear(), today.getMonth() + 1, today.getDate());
let payload = `今天是國曆${date}農曆${lunarDate.lunarMonth}月${lunarDate.lunarDay}日`;

switch (lunarDate.lunarDay) {
    case 1:
        payload += ' 初一';
        break;
    case 2:
        payload += ' 初二';
        break;
    case 3:
        payload += ' 初三';
        break;
    case 4:
        payload += ' 初四';
        break;
    case 5:
        payload += ' 初五';
        break;
    case 6:
        payload += ' 初六';
        break;
    case 7:
        payload += ' 初七';
        break;
    case 8:
        payload += ' 初八';
        break;
    case 9:
        payload += ' 初九';
        break;
    case 10:
        payload += ' 初十';
        break;
    case 15:
        payload += ' 十五';
        break;
    default:
        break;
}

return { payload };

測試用的flow
