链判断运算符特地好用,我就不多说了,搭建 vite 时,发现用了很多办法,都不能反对

办法一:@vitejs/plugin-react-refresh 配置 parserPlugins,不失效

import {defineConfig} from 'vite';
import reactRefresh from '@vitejs/plugin-react-refresh';

export default defineConfig({
    plugins: [
        reactRefresh({parserPlugins: ['optionalChaining', 'nullishCoalescingOperator']
        })
    ]
});

办法二:vite-babel-plugin 加 babel,不失效

import {defineConfig} from 'vite';
import reactRefresh from '@vitejs/plugin-react-refresh';
import babel from 'vite-babel-plugin';

export default defineConfig({
    plugins: [babel(),
        reactRefresh({parserPlugins: ['optionalChaining', 'nullishCoalescingOperator']
        })
    ]
});

办法三:@rollup/plugin-babel 加 babel,不失效

import {defineConfig} from 'vite';
import reactRefresh from '@vitejs/plugin-react-refresh';
import babel from '@rollup/plugin-babel';

export default defineConfig({
    plugins: [
        babel({
            babelHelpers: 'runtime',
            plugins: [
                '@babel/plugin-proposal-nullish-coalescing-operator',
                '@babel/plugin-proposal-optional-chaining'
            ]
        }),
        reactRefresh({parserPlugins: ['optionalChaining', 'nullishCoalescingOperator']
        })
    ]
});

办法四:改 tsconfig.json,仍然没成果

{
    "compilerOptions": {
        "target": "ES5",
        "lib": [
            "DOM",
            "DOM.Iterable",
            "ESNext",
            "ES2020",
            "ES2020.Symbol.WellKnown",
            "ES2020.String",
            "ES2020.SharedMemory",
            "ES2020.Promise",
            "ES2020.Intl",
            "ES2020.BigInt",
            "ES2021",
            "ES2021.Promise",
            "ES2021.String",
            "ES2021.WeakRef",
            "ES2019",
            "ES2019.Array",
            "ES2019.Object",
            "ES2019.String",
            "ES2019.Symbol",
            "ES2017",
            "ES2017.Object",
            "ES2015",
            "ES2015.Core"
        ],
        "allowJs": false,
        "skipLibCheck": false,
        "esModuleInterop": false,
        "allowSyntheticDefaultImports": true,
        "strict": true,
        "forceConsistentCasingInFileNames": true,
        "module": "ESNext",
        "moduleResolution": "Node",
        "resolveJsonModule": true,
        "isolatedModules": true,
        "noEmit": true,
        "jsx": "react"
    },
    "include": ["./src"]
}

试了这么多办法,都没用,我心田是解体的,没方法,还要到 node_modules 里找 @vitejs/plugin-react-refresh,钻研一下源码,我感觉我在 parserPlugins 里加 optionalChaining 和 nullishCoalescingOperator,没有成果,我就重点看了这里,而后在源码里强制 require 这两个 babel 插件,再 yarn add/npm install 这两个插件,这次终于起作用了,快乐的我想吐血,心愿尤大大看到这个,优化一下 @vitejs/plugin-react-refresh
