VError-Chain

这个库是构建在 verror 库之上的, 在 Error 对象上扩展方法, 并封装成 VError 对象. 提供便利 的 error wrap 和 chain 机制.

注意这个库会污染 Error 实例的几个方法.

this lib is a simple wrapper builded upon verror lib. it injects a few helper methods into Error & Error.prototype to help you with error chainning & wrapping. In doing so it apparently pollutes Error and its instance. So use it with care.

示例:

import '@jing.miao/verror-chain'; // 

try {
  await fs.readFileSync('something-not-existed')
} catch (err){
  return err.chain({name: 'FILE_NOT_EXISTED'})
}

Api

-> Error.chain(options) options is the same parameters but with only one exception that is name field is required.

-> Error.verror -> Error.werror a helper function wrap around new VError()/WError().

-> Error.of(t: string | object | Error) create a new Error().
