如何在Nuxt.js中实现流程类型

问题描述

我目前正在尝试将现有的vue.js项目转换为nuxt.js.我无法在nuxt.js中添加流类型支持.当我运行流服务器时，它说没有错误！但运行npm run dev时，它会在流语法上引发错误.

I am currently trying to convert our existing vue.js project into nuxt.js. I am unable to add flowtype support in nuxt.js. when i run the flow server it says no errors!! but running npm run dev, its throwing error on the flow syntax.

.flowconfig

[include]
pages/**/.*
components/**/.*
layouts/**/.*
apiRoutes/.*
store/.*
utils/.*


[ignore]
.*/build/.*
.*/config/.*
.*/dist/.*
.*/node_modules/.*
.*/static/.*
.*/test/.*
.*/ssl/.*
.*/.nuxt/.*

[libs]
./flow/

[options]
emoji=true
module.file_ext=.vue
module.file_ext=.js
server.max_workers=3
log.file=./flow.log
suppress_comment= \\(.\\|\n\\)*\\$FlowFixMe
unsafe.enable_getters_and_setters=true
module.system.node.resolve_dirname=node_modules
module.name_mapper='^.*\.css$' -> 'empty/object'
module.name_mapper='^.*\.js$' -> 'empty/object'
module.name_mapper='^@/\(.*\)$' -> '<PROJECT_ROOT>/\1'

我添加了所有必要的babel和eslint软件包.

i've added all the neccessary babel and eslint packages.

.babelrc
{
  "presets": [
    ["env", { "modules": false }],
    "stage-2",
    ["es2015", {"modules": false }],
    "flow-vue"
  ],
  "plugins": [
    "transform-runtime",
    "transform-class-properties",
    "syntax-flow",
    "transform-flow-strip-types"
  ],
  "comments": false,
  "env": {
    "test": {
      "presets": ["env", "stage-2"],
      "plugins": [ "istanbul" ]
    }
  }
}

---

.eslintrc.js
module.exports = {
  root: true,
  parserOptions: {
    parser: 'babel-eslint',
    sourceType: 'module'
  },
  env: {
    browser: true,
    node: true,
    jquery: true
  },
  extends: [
    'standard',
    'plugin:flowtype/recommended'
    // 'plugin:vue/recommended'
  ],
  // required to lint *.vue files
  plugins: [
    'html',
    'flowtype-errors',
    'flowtype'
  ],
  // add your custom rules here
  rules: {
    'flowtype-errors/show-errors': 2,
    // allow paren-less arrow functions
    'arrow-parens': 0,
    'semi': ["error", "always"],
    // allow async-await
    'generator-star-spacing': 0
  },
  globals: {}
}

在运行npm run dev时，它不会解析流类型语法

On running npm run dev, it doesnt parse flowtype syntax

推荐答案

我建议按照上的说明进行操作流程网站以设置Babel.特别是有一个预设，因此您无需配置单个规则.然后，您实际上需要运行Babel(同样，说明在网站上).运行Babel之后，您应该能够运行它在Node中输出的代码.

I suggest following the instructions on the flow website to set up Babel. In particular there is a preset, so you shouldn't need to configure individual rules. Then you'll actually need to run Babel (again, instructions are on the website). Once you have run Babel, you should be able to run the code it outputs in Node.
