eslint-plugin-light v1.0.3
Eslint Plugin Light
Simple Eslint plugin.
1. Installation
You need to install ESLint first.
npm i eslint -DNext, install eslint-plugin-light.
npm i eslint-plugin-light -D2. Usage
Add light to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:
{
"plugins": [
"light"
]
}Then configure the rules you want to use under the rules section.
{
"rules": {
"light/rule-name": 2
}
}or use extends:
{
"extends": ["plugin:light/recommended"],
}3. Supported Rules
3.1. light/valid-vue-comp-import
禁止从js文件中加载Vue组件
比如,
- 导入地址是
js/ts文件
import SomeComp from 'src/local-component/ui/pages/user/account-manage/index.js';
// 或者省略了js/ts文件后缀
import SomeComp from 'src/local-component/ui/pages/user/account-manage/index';如果加了 --fix,会被转换为:
import SomeComp from 'src/local-component/ui/pages/user/account-manage/xxx.vue';注意上面的xxx.vue是从index.js中分析得到的原始文件路径。
- 导入一个目录,但目录存在
index.js,这时候不管存不存在index.vue,uni-app转换都会失败
import SomeComp from 'src/local-component/ui/pages/user/account-manage';可转换为:
import SomeComp from 'src/local-component/ui/pages/user/account-manage/xxx.vue';- 具名导入
import {
AComp,
BComp,
CComp,
DComp,
} from './comp';可转换为:
import AComp from 'src/local-component/module/tip-match/tip-match-schedule-tree-new/comp/a.vue';
import BComp from 'src/local-component/module/tip-match/tip-match-schedule-tree-new/comp/b.vue';
import CComp from 'src/local-component/module/tip-match/tip-match-schedule-tree-new/comp/c.vue';
import DComp from 'src/local-component/module/tip-match/tip-match-schedule-tree-new/comp/d.vue';3.2. light/no-plus-turn-number
禁止在vue的template中用+号转换字符串为数字
比如:
<ScheduleItem
:child-id="+childId"
/>如果加了--fix,会被转化成:
<ScheduleItem
:child-id="parseInt(childId, 10)"
/>3.3 no-complex-key
不要在vue模板中使用复杂的key。包括:
字符串拼接,如:
:key="`hold` + index"`- 模板字符串,如:
:key="`hold-${index}`"- 将
key提到一个函数中,如:
:key="getHoldKey(index)"
getHoldKey(index) {
return `hold${index}`
}最佳方式其实是提前处理好数据,这样性能会更好,也避免了key重复。
getData() {
items = items.map((item,index) => ({
...item,
key: `hold-${index}`
}))
}uni-app中,key重复的话,会造成挂载在组件上面的事件参数为undefined,从而不成功。
3.4 json-parse-try-catch
JSON.parse 应该加 try catch。
默认配置会排除下面情况:
JSON.parse(JSON.stringify(abc));可以配置 strict 参数为 true,开启检查。
// .eslintrc.js
module.exports = {
plugins: [
'light',
],
rules: {
'light/json-parse-try-catch': [2, { strict: true }],
},
}
