How to use import-fresh - 10 common examples

async updateDatabase() {

export default (file, program, appConfig) => {
  const context = getContext();

  let configFile = file;
  if (['.js', '.json'].indexOf(extname(file)) < 0) {

  }
  // 为了测试方便，增加 `process.env.CONTEXT`
  const pathInProject = resolve(context ? join(context, configFile) : configFile);
  const pathInLib = resolve(__dirname, '..', configFile);

  // 此处不能使用 require.cache
  // 因为该方法依赖 process.env.CONTEXT
  // 而在跑测试用例时会在不同的用例设置不同的 process.env.CONTEXT
  // 使用 require.cache 就会导致除第一次外的所有结果都从缓存中加载，从而引发错误
