Webpack-Yaml-> JSON->提取文件 [英] Webpack - Yaml -> JSON -> Extract file

问题描述

我有一个带有一些翻译的YAML文件.我需要将这些文件转换为JSON文件.我试过使用yaml-import-loader和json-loader，但出现错误.

I have a YAML file with a few translations. I need to transform these files into a JSON file. I've tried using yaml-import-loader and json-loader but I get an error.

这是我的设置:

const ExtractTextPlugin = require('extract-text-webpack-plugin');

const extractEnglish = new ExtractTextPlugin('lang/en.js');

module.exports = {
  entry: [
    './src/locales/application.en.yml',
  ],
  output: {
    filename: 'english.js',
  },
  module: {
    strictExportPresence: true,
    rules: [
      {
        test: /\.en\.yml$/,
        use: extractEnglish.extract({
          use: [
            // { loader: 'json-loader' },
            {
              loader: 'yaml-import-loader',
              options: {
                output: 'json',
              },
            }],
        }),
      },
    ],
  },
  plugins: [
    extractEnglish,
  ],
};

我得到的错误:

Users/xxx/Documents/Project/node_modules/extract-text-webpack-plugin/dist/index.js:188
            chunk.sortModules();
                  ^

TypeError: chunk.sortModules is not a function
    at /Users/xxx/Documents/Project/node_modules/extract-text-webpack-plugin/dist/index.js:188:19

无论是否注释json-loader，都是相同的错误.

Same error whether or not the json-loader is commented or not.

我真的不明白是怎么回事.

I really don't understand what is going wrong.

版本: "webpack":"2.6.1"， "extract-text-webpack-plugin":"^ 3.0.0"， "json-loader":"^ 0.5.7"，

Versions: "webpack": "2.6.1", "extract-text-webpack-plugin": "^3.0.0", "json-loader": "^0.5.7",

推荐答案

不确定是否会帮助您解决问题，但是最近我找到了解决i18n加载问题的方法.我这样做是为了将YAML预先提取到JSON文件中，因为我使用angular-translate并需要动态地按需加载文件.我避免使用extract-text-webpack-plugin，而只使用加载程序:file-loader和yaml-loader.

Not sure if this will help your situation but I recently found a solution to my i18n loading problem. I do this to extract YAML into JSON files upfront as I use angular-translate and needed to load files dynamically and on-demand. I avoid extract-text-webpack-plugin and use only loaders: file-loader and yaml-loader.

首先，我在源代码的开头附近设置.yaml文件的导入(在我的情况下，是特定的一系列导入文件供webpack处理)

First I setup the import of my .yaml files near the beginning of source (in my case a specific chain of import files for webpack to process)

 import "./i18n/en.user.yaml";

我更新了webpack配置，将YAML转换为JSON，并使其可以动态加载(所有内容都来自我的"src"目录，因此是上下文):

I updated webpack config to translate YAML to JSON and have it available to load dynamically (everything originates from my 'src' directory, hence the context):

 rules: [{
   test: /.\.yaml$/,
   use: [{
     loader: 'file-loader',
     options: {
       name: '[path][name].json',
       context: 'src'
      }
    },{
      loader: 'yaml-loader'
    }]
  }]

这将转换我的yaml文件并将其导出到我的公共目录，在本例中为"/i18n/en.user.json".

This will translate my yaml file(s) and export them to my public directory, in this case at '/i18n/en.user.json'.

现在，当angular-translate通过$ http按需上传我配置的i18n设置时，它已经具有解析的YAML，并且避免了必须在前端使用js-yaml(或类似名称)对其进行解析.

Now when angular-translate uploads my configured i18n settings via $http on-demand, it already has the parsed YAML and avoids having to parse it with js-yaml (or similar) on the front end.
