无服务器 webpack 不捆绑 handlers.js

Question

我是 webpack 和无服务器的新手，如果这看起来微不足道，请原谅我。我从 npm serverless-webpack 复制了这些代码。

我尝试使用 serverless webpack --out dist，但我的命令行无法识别 webpack。如果我尝试 serverless deploy <opts> <opt>，那么它会编译并捆绑到 .serverless 中，但缺少必要的 JS 文件。

webpack.config.js

var path = require('path');
var slsw = require('serverless-webpack');
var nodeExternals = require('webpack-node-externals');

module.exports = {
  context: path.resolve(__dirname, './src'),
  entry: slsw.lib.entries,
  target: 'node',
  externals: [nodeExternals()],
  output: {
    libraryTarget: 'commonjs',
    path: path.resolve(__dirname, '.webpack'),
    filename: '[name].js',
  },
  module: {
    rules: [
      {
        test: /\.jsx$/,
        loader: ["babel-loader"],
        include: __dirname,
        exclude: /node_modules/
      }
    ]
  }
};

Serverless.yml

service: hello-world
frameworkVersion: '>=1.2.0 <2.0.0'
provider:
  name: aws
  runtime: nodejs8.10
  deploymentBucket:
     name: test-bucket
plugin:
  - serverless-webpack
  - serverless-prune-plugin
custom:
  prune:
    automatic: true
    number: 3
  webpack: webpack.config.js
  webpackIncludeModules:
    packagePath: ./src/package.json
    forceInclude:
       - express
       - body-parser
functions:
  getHelloWorld:
    handler: functions/test.hello
    events:
      - http:
          path: test/hello
          method: get

webpack: 4.22.0（全局）

serverless-webpack: 5.3.0（全球）

Answer 1

首先，安装webpack。
```
npm install --save-dev webpack
```

安装插件serverless webpack

npm install serverless-webpack --save-dev

将插件添加到 serverless.yml

service: hello-world
plugins:
    - serverless-webpack
custom:
    webpackIncludeModules: true

您的 package.json 将是：

"scripts": {
    "test-process": "mocha --require babel-core/register ./tests/unit.test.js",
    "deploy": "./node_modules/.bin/serverless remove --stage dev --region us-east-1 && ./node_modules/.bin/serverless deploy -v --stage dev --region us-east-1"
}

然后，您可以使用此命令进行部署：npm 运行 deploy
还有 mocha you can test your code before doing the deploy. For that, you will have that configure babel

我为您准备了一个使用 webpack4 和无服务器的基本示例 hello-world：

别忘了，在apigateway中添加响应application/json：

让我知道效果如何..
