获取 https://www.latexlive.com 上的数据，配置到cherry上的方法
至于怎么获取 api.json，参考 https://www.latexlive.com

const fs = require('node:fs');

const jsonStr = fs.readFileSync('./api.json', 'utf8');

const api = JSON.parse(jsonStr);

const myobj = {};

const oss = 'https://latexlive-resourse.oss-cn-beijing.aliyuncs.com';

api.shortcut.reduce((acc, cur) => {
  const obj = {
    title: cur.descript,
    subCategory: {},
  };
  cur.layer1.cont.reduce((layer1Acc, layer1Cur) => {
    const obj2 = {
      title: layer1Cur.descript,
      img: oss + cur.layer1.path + layer1Cur.name,
      formulas: cur.layer2.cont[layer1Cur.tag].cont.map((layer2Val) => {
        let img = '';
        let name = '';
        if (layer2Val.name.includes('.svg') || layer2Val.name.includes('.png')) {
          img = `${oss + cur.layer2.path + layer1Cur.tag}/${layer2Val.name}`;
        } else {
          name = layer2Val.name;
        }
        let formulaStyle = '';
        if (layer2Val.latex !== '') {
          const isNum = isNaN(Number(cur.layer2.cont[layer1Cur.tag].defaultsize));
          formulaStyle = `width: ${cur.layer2.cont[layer1Cur.tag].defaultsize}${isNum ? '' : 'rem'}`;
        }
        return {
          name,
          img,
          latex: layer2Val.latex,
          formulaStyle,
        };
      }),
    };
    layer1Acc[layer1Cur.tag] = obj2;
    return layer1Acc;
  }, obj.subCategory);
  acc[cur.name] = obj;
  return acc;
}, myobj);

console.log(JSON.stringify(myobj));
