在旧版浏览器上使用Fetch进行ReactJS [英] ReactJS with Fetch on older browsers

问题描述

我正在用Webpack和Babel实现React JS.但是，我无法让Fetch与IE 11一起使用.

.babelrc文件中包含以下内容:

{
  "presets" : ["env", "stage-0", "react"]
}

以及我的webpack.config.js文件中的以下内容:

var webpack = require('webpack');
var path = require('path');

var DIST_DIR = path.resolve(__dirname, 'dist');
var SRC_DIR = path.resolve(__dirname, 'src');

var config = {
  entry: {
    bundle: [
      'babel-polyfill',
      SRC_DIR + '/app/index.js',
    ]
  },
  output: {
    path: DIST_DIR + '/public/js',
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        include: SRC_DIR,
        loader: 'babel-loader'
      }
    ]
  }
};

module.exports = config;

根据我的理解，实施babel-preset-env，stage-0和babel-polyfill应该可以将Fetch API转换为较旧的浏览器可以理解的东西.还有其他我想念的东西吗?

解决方案

fetch不是EcmaScript的一部分，而是网络平台的一部分. Babel只是编写最新Javascript的编译器.如果要在较旧的浏览器中使用fetch，则需要类似此版本

的polyfill

I am implementing React JS, with Webpack and Babel. However, I am having trouble getting Fetch to work with IE 11.

I have the following in my .babelrc file:

{
  "presets" : ["env", "stage-0", "react"]
}

and the following in my webpack.config.js file:

var webpack = require('webpack');
var path = require('path');

var DIST_DIR = path.resolve(__dirname, 'dist');
var SRC_DIR = path.resolve(__dirname, 'src');

var config = {
  entry: {
    bundle: [
      'babel-polyfill',
      SRC_DIR + '/app/index.js',
    ]
  },
  output: {
    path: DIST_DIR + '/public/js',
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        include: SRC_DIR,
        loader: 'babel-loader'
      }
    ]
  }
};

module.exports = config;

From my understanding implementing babel-preset-env, stage-0, and babel-polyfill should have allowed for the Fetch API to be transpiled into something older browsers could understand. Is there something else that I am missing?

解决方案

fetch isn't part of EcmaScript but its part of the web platform. Babel is only a compiler to write the latest Javascript. If you want to use fetch in older browsers you need a polyfill like this one
