typescript配置alias的详细步骤
1 安装依赖
npm install --save-dev babel-plugin-module-resolver
# yarn add babel-plugin-module-resolver --dev
根目录新增.babelrc文件
参考以下内容按您项目中的需要去修改
{
"presets": ["next/babel"],
"plugins": [
[
"module-resolver",
{
"alias": {
"@/actions": "./actions",
"@/components": "./components",
"@/constants": "./constants",
"@/pages": "./pages",
"@/public": "./public",
"@/reducers": "./reducers",
"@/utils": "./utils"
}
}
]
]
}
修改tsconfig.json文件
{
"compilerOptions": {
"baseUrl": "./",
"paths": {
"@components/*": ["./components/*"],
"@pages/*": ["./pages/*"],
"@public/*": ["./public/*"]
}
}
}
注意"baseUrl": "./",不能省去，否则ts报Option 'paths' cannot be used without specifying '--baseUrl' option.错误
next.js中配置alias也可以参考如上步骤
