WebPack 2.1.0-beta.25 postLoaders błąd nieznany własności

Question

WebPack 2.1.0-beta.25 (przynajmniej beta 23+) wyrzuca następujący błąd gdybym określić postLoaders: [] w moim webpack.config:

(tylko ciekawe bit):

configuration.module has an unknown property 'postLoaders'. 

(pełny stos):

23 09 2016 13:37:31.599:ERROR [preprocess]: Can not load "webpack"! 
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

Moja webpack.config:

process.env.npm_lifecycle_event = 'test'; 
var webpack = require('webpack'); 
var path = require('path'); 
var NODE_MODULES = root("node_modules"); 

function root(args) { 
    args = Array.prototype.slice.call(arguments, 0); 
    return path.join.apply(path, [__dirname].concat(args)); 
} 

module.exports = { 
    entry: {}, 

    resolve: { 
     modules: [root(""), NODE_MODULES], 
     extensions: [".ts", ".js", ".json", ".css", ".scss", ".html"] 
    }, 

    module: { 
     loaders: [ 
      { 
       test: /\.ts$/, 
       loader: "ts", 
       query: { 
        "ignoreDiagnostics": [ 
         2403, // 2403 -> Subsequent variable declarations 
         2300, // 2300 -> Duplicate identifier 
         2374, // 2374 -> Duplicate number index signature 
         2375, // 2375 -> Duplicate string index signature 
         2502 // 2502 -> Referenced directly or indirectly 
        ] 
       }, 
       exclude: [/node_modules\/?!(@angular)/] 
      }, 

      { test: /\.scss$/, loader: "null" }, 
      { test: /\.css$/, loader: "null" }, 
      { test: /\.html$/, loader: "raw" } 
     ], 
     postLoaders: [ 
      { 
       test: /\.(js|ts)$/, 
       include: [root("")], 
       loader: "istanbul-instrumenter-loader", 
       exclude: [/.+-spec\.ts$/, /\.e2e\.ts$/, NODE_MODULES] 
      } 
     ] 
    } 
}; 

Wygląda na to, że dokumentacja dla ładowarek na stronie sieci Web wciąż odwołuje się do pre/postLoaders. Ale jeden, nawet pusty, nadal będzie generował ten błąd.

Czy schemat został zmieniony? Gdzie powinien iść postLoader lub jak skonfigurować usługę PostLoader?

Answer 1

Jest nowy enforce: pre lub post nieruchomość, która jest wprowadzona w Uwagi do wydania v2.1.0-beta.24 i v2.1.0-beta.25: https://github.com/webpack/webpack/releases

musieliśmy przenieść obciążenia wstępnego z:

module: { 
    preLoaders: [ 
    { 
     test: /\.jsx?$/, 
     loader: 'eslint', 
     exclude: /(node_modules)/ 
    } 
    ], 
    loaders: [ 
    ... 
    ] 
} 

do tego:

module: { 
    loaders: [ 
    { 
     test: /\.jsx?$/, 
     loader: 'eslint', 
     exclude: /(node_modules)/, 
     enforce: 'pre' 
    }, 
    ... 
    ] 
} 

Więc domyślam się, że twoja konfiguracja zakończyłaby się wyglądając coś w stylu:

process.env.npm_lifecycle_event = 'test'; 
var webpack = require('webpack'); 
var path = require('path'); 
var NODE_MODULES = root("node_modules"); 

function root(args) { 
    args = Array.prototype.slice.call(arguments, 0); 
    return path.join.apply(path, [__dirname].concat(args)); 
} 

module.exports = { 
    entry: {}, 

    resolve: { 
     modules: [root(""), NODE_MODULES], 
     extensions: [".ts", ".js", ".json", ".css", ".scss", ".html"] 
    }, 

    module: { 
     loaders: [ 
      { 
       test: /\.ts$/, 
       loader: "ts", 
       query: { 
        "ignoreDiagnostics": [ 
         2403, // 2403 -> Subsequent variable declarations 
         2300, // 2300 -> Duplicate identifier 
         2374, // 2374 -> Duplicate number index signature 
         2375, // 2375 -> Duplicate string index signature 
         2502 // 2502 -> Referenced directly or indirectly 
        ] 
       }, 
       exclude: [/node_modules\/?!(@angular)/] 
      }, 

      { test: /\.scss$/, loader: "null" }, 
      { test: /\.css$/, loader: "null" }, 
      { test: /\.html$/, loader: "raw" }, 

      { 
       test: /\.(js|ts)$/, 
       include: [root("")], 
       loader: "istanbul-instrumenter-loader", 
       exclude: [/.+-spec\.ts$/, /\.e2e\.ts$/, NODE_MODULES], 
       enforce: 'post' 
      } 
     ] 
    } 
};
