react-native 相对项目路径导入组件 ___ babel-plugin-root-import

本文介绍了一个Babel插件Babel-Root-Importer的使用方法,该插件能够简化React-Native项目中相对路径的导入,通过设置项目根路径前缀和别名,实现更简洁的代码结构。

在使用react-native的时候,经常要自定义很多组件,但是只能使用../../../的方式,经常不记得这是多深,有没有一个插件,能自动帮我们解决这样的问题?

使用指南

我们使用的目标要达到以下的使用效果

// 通常
import SomeExample from '../../../some/example.js';
或
const OtherExample = require('../../../other/example.js');
// 使用了 Babel-Root-Importer 之后
import SomeExample from '~/some/example.js';
或
const OtherExample = require('~/other/example.js');

组件安装

npm 方式

npm install babel-plugin-root-import --save-dev

yarn 方式

yarn add babel-plugin-root-import --dev

配置

增加一个 .babelrc项目根目录,并写入(如果已有,则加入plugins):

{
  "plugins": [
    [
      "babel-plugin-root-import"
    ]
  ]
}

温馨提示

已有项目,记得清理一个缓存(先关闭所有控制侦听程序)

watchman watch-del-all
npm start -- --reset-cache

扩展

自定义根路径前缀

如果你想把src/js作为项目根入口,你可以修改.babelrc为以下内容:

{
  "plugins": [
    [
      "babel-plugin-root-import",
      {
        "rootPathSuffix": "src/js"
      }
    ]
  ]
}

如何你想修改项目的默认根入口别名,默认~

{
  "plugins": [
    [
      "babel-plugin-root-import", {
        "rootPathPrefix": "@"
      }
    ]
  ]
}

也可以定义多组别名入口

{
  "plugins": [
    ["babel-plugin-root-import", [{
      "rootPathPrefix": "~", // `~` 默认
      "rootPathSuffix": "src/js"
    }, {
      "rootPathPrefix": "@",
      "rootPathSuffix": "other-src/js"
    }, {
      "rootPathPrefix": "#",
      "rootPathSuffix": "../../src/in/parent" //也支持父级路径
    }]]
  ]
}

// 然后你就可以这样使用插件了。

import foo from '~/my-file';
const bar = require('@/my-file');
