M1#A08: Problema ao executar o "npm start"

wandrebarbosa commented 3 years ago

Bom tarde, @fdaciuk , conforme sua dica na issue da colega no outro dia, instalei o webpack local (npm install --save-dev webpack-dev-server@1) e ainda continuo com o problema.

segue abaixo meus seguintes trechos de códigos:

########################### server.js:

'use strict'

const webpack = require('webpack')
const WebpackDevServer = require('webpack-dev-server')
const config = require('./webpack.config')

new WebpackDevServer(webpack(config), {
  publicPath: config.output.publicPath,
  hot: true,
  historyApiFallback: true,
  stats: { colors: true }
}).listen(3000, (err) => {
  if (err) {
    return console.log(err)
  }

  console.log('Listening on http://localhost:3000')
})

########################### package.json:

{
  "scripts": {
    "start": "node server.js"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^6.4.1",
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-0": "^6.24.1",
    "react-hot-loader": "^3.0.0-beta.2",
    "webpack": "^1.15.0",
    "webpack-dev-server": "^1.16.5"
  },
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2"
  }
}

########################### webpack.config.js:

'use strict'

const path = require('path')
const webpack = require('webpack')

module.exports = {
  devtool: 'source-map',

  entry: [
    'react-hot-loader/patch',
    'webpack-dev-server/client?http://localhost:3000',
    'webpack/hot/only-dev-server',
    path.join(__dirname, 'src', 'index')
  ],

  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/dist/'
  },

  plugins: [
    new webpack.HotModuleReplacementPlugin()
  ],

  module: {
    loaders: [{
      test: /\.js$/,
      exclude: /node_modules/,
      include: /src/,
      loader: 'babel'
    }]
  }
}

continuo ainda ao aplicar o npm start o erro abaixo:

Rodando pelo npm o comando correto seria "npm run start", ele precisa de "run" no comando para executar a ação, espero ter ajudado..

Infelizmente isso não funcionou amigo, @2lipe.

fdaciuk commented 3 years ago

Oi @wandrebarbosa! Para o comando start, não precisa do run =) No seu caso, o problema é que você instalou o webpack-dev-server, mas não instalou o webpack. Instalando ele, ao rodar o npm start tudo deve funcionar como esperado :)

Boa noite @fdaciuk , desculpa a demora, faculdade e TCC nesse semestre ta osso, conseguir aqui sim, obrigado, continuando o curso, esta ótimo a proposito.
