Vue.js:Nuxt错误处理

JavaScript

苦苦挣扎以设置vuex的错误处理。似乎有很多方法可以做到这一点,并且关于正确的错误处理的文档很少。尽管尚未找到令人满意的解决方案,但我一直在尝试四种替代方案。


备选方案1- 捕获和处理组件上的错误

pages / login.vue中:

export default {
    methods: {
        onLogin() {
            this.$store.dispatch('auth/login', {
                email: this.email,
                password: this.password,
            }).then(() => {
                this.$router.push('/home');
            }).catch((error) {
                // handle error in component
            });
        },
    },
}

store / auth.js中:

export const actions = {
    login({ commit }, { email, password }) {
        return this.$axios.post('/api/login', {
            email,
            password,
        }).then((res) => {
            doSomething(res);
        });
    },
}

优点

缺点

  • 错误未处理并存储在vuex中。
  • 在组件方法中引入了许多样板代码。

备选方案2- vuex中的捕获和处理错误

pages / login.vue中:

export default {
    methods: {
        onLogin() {
            this.$store.dispatch('auth/login', {
                email: this.email,
                password: this.password,
            }).then(() => {
                this.$router.push('/home');
            });
        },
    },
}

store / auth.js中:

export const actions = {
    login({ commit }, { email, password }) {
        return this.$axios.post('/api/login', {
            email,
            password,
        }).then((res) => {
            doSomething(res);
        }).catch((error) => {
            // store error in application state
            commit('SET_ERROR', error);
        });
    },
}

优点

  • vuex可从任何组件访问错误对象
  • 可以在布局中使用反应性错误组件,当错误状态更改时会显示出来。

缺点

  • 我不确定是否有办法跟踪错误的来源以及从哪个组件抛出错误。

Alternative 3 - Catching errors using axios interceptors

in plugins/axios.js:

export default function({ $axios, store }) {
    $axios.onError(error => {
        store.dispatch('setError', error);
    });
}

in pages/login.vue:

export default {
    methods: {
        onLogin() {
            this.$store.dispatch('auth/login', {
                email: this.email,
                password: this.password,
            }).then(() => {
                this.$router.push('/home');
            });
        },
    },
}

in store/auth.js:

export const actions = {
    login({ commit }, { email, password }) {
        return this.$axios.post('/api/login', {
            email,
            password,
        }).then((res) => {
            doSomething(res);
        });
    },
}

PROS

  • Global error handling
  • No need to catch errors in either vuex or component
  • No boiler-plate code

CONS

  • All exceptions are unhandled, meaning non-axios errors are uncaught.

Alternative 4 - Custom error plugin

I've been experimenting in implementing a custom plugin that catches all exceptions, but I'm not succeeding in making it work.

in plugins/catch.js:

export default (ctx, inject) => {
    const catchPlugin = function (func) {
        return async function (args) {
            try {
                await func(args)
            } catch (e) {
                return console.error(e)
            }
        }
    };
    ctx.$catch = catchPlugin;
    inject('catch', catchPlugin);
}

in pages/login.vue:

export default {
    methods: {
        onLogin: this.$catch(async function () {
            await this.$store.dispatch('auth/login', { email: this.email, password: this.password });
            this.$router.push('/home');
        }),
    },
}

PROS

  • No boilerplate.
  • All errors caught in plugin.

CONS

  • I cannot make it work. :(

我的印象是,缺少有关vue / nuxt中错误处理的文档。有人可以选择第四个替代方法吗?这样理想吗?还有其他选择吗?什么是常规?

感谢您的时间!
