如何为AWS Lambda nodejs运行时构建单个js文件 [英] How do I build a single js file for AWS Lambda nodejs runtime

问题描述

我们正在开发一个有助于在AWS中部署和维护代码的项目/框架 LAMBDA。我想将lambda函数的所有node.js代码构建/捆绑到一个js文件中，因为：

We are working on a project/framework that aids in deploying and maintaining code in AWS Lambda. I want to build/bundle all node.js code for a lambda function into one js file because:

• 较小的代码库有助于lambda冷启动问题


• Lambda的代码拉链大小限制为50MB

我们不想创建一个自定义捆绑工具，因为有很多选项（systemjs，browserify，webpack等）。但是，我们担心某些节点模块与捆绑器/构建器不兼容的问题。

We don't want to create a custom bundler to do this because there are many options already out there (systemjs,browserify,webpack etc). HOWEVER we are concerned with issues with some node modules not playing well with bundlers/builders.

具体 aws-sdk 有 webpack的已知问题，说它有浏览支持但我已经与浏览过awts-sdk问题的人进行了交谈

Specifically aws-sdk has known issues with webpack, says it has browserify support but I've talked to people who have had issues with browserify'ing aws-sdk

我们想选择一个现有的捆绑器（或2），但我们希望确保它适用于尽可能多的模块/代码。我们正在尝试为JAWS创建一个插件生态系统，所以要做到这一点非常重要（不要让人们关闭，因为他们使用的模块X不会捆绑）。

We want to pick an existing bundler (or 2), but we want to make sure it works for as many modules/code as possible. We are trying to create a plugin ecosystem for JAWS, so getting this right is important (don't want to turn people off because module X they use wont bundle).

问题：

1. 我如何进行捆绑/构建以满足这些约束条件？


2. 是否存在我们可以向消费者提供我们产品的任何指导方针，以确保他们编写/使用的代码捆绑在一起？例如：动态require（）导致问题AFAIK。

推荐答案

aws-sdk-js 现在正式支持browserify 。你可以为什么这是一件好事在我的博客上。

aws-sdk-js now officially supports browserify. You can why this is a great thing on my blog.

我创建了一个名为 serverless-plugin-browserify 将以极少的配置完成所有繁重的任务。

I have created a serverless plugin called serverless-plugin-browserify that will do all the heavy lifting with very minimal configuration.

要具体回答这个问题，我用这个browserify配置解决了这个问题：

To answer the question specifically, I solved the problem with this browserify config:

{
  disable: false, //Not an official option, used as internal option to skip browserify
  exclude: [],    //Not an option, but will use for setting browserify.exclude() if defined in yml
  ignore:  [],    //Not an option, but will use for setting browserify.ignore() if defined in yml

  basedir:          this.serverless.config.servicePath,
  entries:          [],
  standalone:       'lambda',
  browserField:     false,  // Setup for node app (copy logic of --node in bin/args.js)
  builtins:         false,
  commondir:        false,
  ignoreMissing:    true,  // Do not fail on missing optional dependencies
  detectGlobals:    true,  // We don't care if its slower, we want more mods to work
  insertGlobalVars: {      // Handle process https://github.com/substack/node-browserify/issues/1277
    //__filename: insertGlobals.lets.__filename,
    //__dirname: insertGlobals.lets.__dirname,
    process: function() {
    },
  },
  debug:            false,
}
