当使用Firebase config.ts文件设置Vue 3+Quasar时，我得到了以下eslint错误:"

Question

我刚刚使用Quasar CLI设置了一个新的Vue 3 Quasar项目。

我创建了一个新的src/firebase/config.ts文件来存储我的firebase配置，它看起来像这样：

// Import the functions you need from the SDKs you need
import { initializeApp } from 'firebase/app';
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries
import { getFirestore, serverTimestamp } from 'firebase/firestore';
import { getAuth } from 'firebase/auth';
import { getStorage } from 'firebase/storage';
// Your web app's Firebase configuration
const firebaseConfig = {
  apiKey: 'REDACTED',
  authDomain: 'REDACTED',
  projectId: 'REDACTED',
  storageBucket: 'REDACTED',
  messagingSenderId: 'REDACTED',
  appId: 'REDACTED',
  measurementId: 'REDACTED',
};
// Initialize Firebase
const firebaseApp = initializeApp(firebaseConfig);
//Export modules
export const db = getFirestore(firebaseApp);
export const store = getStorage(firebaseApp);
export const auth = getAuth(firebaseApp);
export const timestamp = serverTimestamp();

但是const firebaseApp = initializeApp(firebaseConfig);行正在抛出Unsafe assignment of an 'any' value. eslint@typescript-eslint/no-unsafe-assignment的esint错误。

以下是Quasar CLI在项目创建过程中生成的.eslintrc.js文件：

const { resolve } = require('path');
module.exports = {
  // https://eslint.org/docs/user-guide/configuring#configuration-cascading-and-hierarchy
  // This option interrupts the configuration hierarchy at this file

  },
  // add your custom rules here
  rules: {
    'prefer-promise-reject-errors': 'off',
    // TypeScript
    quotes: ['warn', 'single', { avoidEscape: true }],

    "no-console": process.env.NODE_ENV === "production" ? "warn" : "off",
    "no-debugger": process.env.NODE_ENV === "production" ? "warn" : "off",
  }
}

我不知道为什么我会看到这个错误。

当使用Vue CLI而不是Quasar CLI创建项目时，我不会收到同样的错误。

由于与Quasar CLI .eslintrc.js文件相比，Vue CLI创建了不同类型的.eslintrc.js，我认为问题在于Quasar CLI选择的配置。

以下是使用Vue CLI创建的项目的.eslintrc.js文件的副本。

也许为了修复错误，这个版本的某些部分可以安全地合并到Quasar创建的.eslintrc.js文件中？

module.exports = {
  root: true,
  env: {
    node: true,
  },
  extends: [
    "plugin:vue/vue3-essential",
    "eslint:recommended",
    "@vue/typescript/recommended",
    "@vue/prettier",
    "@vue/prettier/@typescript-eslint",
  ],
  parserOptions: {
    ecmaVersion: 2020,
  },
  rules: {
    "no-console": process.env.NODE_ENV === "production" ? "warn" : "off",
    "no-debugger": process.env.NODE_ENV === "production" ? "warn" : "off",
  },
  globals: {
    defineProps: 'readonly',
    defineEmits: 'readonly',
    defineExpose: 'readonly',
    withDefaults: 'readonly'
  }
};

Answer 1

我不确定这是否有效，但请尝试为您的配置声明类型：

const firebaseConfig: FirebaseOptions = ...

对于你的firebase应用程序：

const firebaseApp: FirebaseApp = initializeApp(firebaseConfig);

并导入这些类型：

import { FirebaseOptions, FirebaseApp, initializeApp } from "firebase/app";

Answer 2

这感觉有点愚蠢，但我所要做的就是重新启动IDE(Visual Studio代码(，错误就消失了。
