基于koa框架，封装typeorm从而进行快速开发

const { createConnection } = require("typeorm");
function loadOrm (config) {
  config.entities = [];
  const entityClassName = [];
  //加载文件
  require("require-all")({
    dirname: config.filePath,
    filter: /(.+)\.ts$/,
    resolve: function (Service) {
      for (let ServiceName in Service) {
        config.entities.push(Service[ServiceName]);
        entityClassName.push(ServiceName);
      }
    },
  });
  const connection = createConnection(config)
    .then((connection) => {
      entityClassName.forEach((e) => {
        connection[e] = connection.getRepository(e);
        console.log(`实体【${e}】加载成功，使用方法：this.ctx.orm.${e}`);
      });
      return connection;
    })
    .catch((err) => {
      console.log(err);
    });
  return async function (ctx, next) {
    if (!ctx.orm) ctx.orm = await connection;
    await next();
  };
};
const Base = require("./lib/base");
module.exports = { Base, loadOrm };
