先来看一个 eslint 报错信息:
error: Expected the Promise rejection reason to be an Error (prefer-promise-reject-errors) at src/views/pages/account/login.vue:42:16:
40 | const validatePass = async(rule: RuleObject, value: string) => {
41 | if (value === '') {
> 42 | return Promise.reject('Please input the password');
| ^
43 | }
44 | if (formState.checkPass !== '') {
45 | formRef.value.validateField('checkPass');
prefer-promise-reject-errors 规则
该规则旨在确保 Promise 只使用 Error 对象拒绝
/*eslint-env es6*/
// Bad
a => {}
// Good
(a) => {}
Options
该规则有一个可选的对象参数:
allowEmptyReject: true (默认为 false) 允许调用不带参数的 Promise.reject()。
假如我想把这个规则禁掉,可以这样配置
// .eslintrc.js
module.exports = {
rules: {
'prefer-promise-reject-errors': 0
},
};
