开发cli插件,有没有异步执行的api

[HCLQ]

What problem does this feature solve?

开发vue-cli插件，希望能有个异步执行api, 执行每个插件的异步任务,完成后再执行webpaclk编译等后续操作

What does the proposed API look like?

想umi的插件api里 _beforeDevServerAsync类似

api.register('_beforeDevServerAsync', () => {
    return new Promise((resolve, reject) => {
      buildDll()
        .then(() => {
          resolve();
        })
        .catch(e => {
          reject(e);
        });
    });
  });

想要在serve和build前先自动打包dll
看来只有注册新命令,执行完dll后,api.service.run('build')这样了么？
