【笔记】采集Hexo文章实现贡献日历

编写Hexo插件，通过采集sitemap.txt站点地图中的文章创建日期作为数据，通过Echarts的日历热力图（Calendar Heatmap）渲染图表，实现贡献日历

• 已部署的站点可以访问站点地图（/sitemap.txt）

创建贡献页面

hexo new page contribute

npm install ajax-for-node
npm install hexo-fs

• 在hexo/scripts目录下创建.js文件作为Hexo脚本

site：这个常量要改成自己的站点域名
start_data：这个常量要改成自己的建站时间

hexo/scripts/GenerateContributeEchartsScript.js

const nodeAjax = require('ajax-for-node');
const fs = require('hexo-fs');

// 站点根目录
const site = `https://loli.fj.cn`;
// 站点地图路径
const site_map = `${site}/sitemap.txt`;
// 正则表达式
const reg = /\d{4}\/\d{2}\/\d{2}/;
// 建站时间
const start_data = new Date("2019-11-22");
// 所有日期
let data_list = [];
// 日期计数
let data_map = new Map();
// 分年度存储
let data_map_year = new Map();
// 文件内容
let file_content = ""

        data_list.push(line);
      }
    }
