Using the bundle We've already decided to use express to send content to the browser.

The handler.js file contains a small wrapper function that wraps the getState() function in AWS' preferred function signature. Also note that Webpack processes Loaders from right to left, so the results of css-loader (the file contents) are passed to style-loader (adding the styles to the HTML document) If we now run Webpack and reload our application the results will look like this: Behind the scenes these two Loaders have dynamically added the styles to the HTML. Note the entry point, and the template, webpack links the two, hence we didn't need to manually add any script tags in the client/index.html.

If you're looking to try this code out, make sure you npm install mongoose webpack webpack-cli first. When Gatsby creates its webpack config, this function will be called allowing you to modify the default webpack config using webpack-merge. Inside this file, export a function called onCreateWebpackConfig. Suppose you have a function that gets a document from the 'State' collection in MongoDB. To add custom webpack configurations, create (if there’s not one already) a gatsby-node.js file in your root directory. Sounds like a textbook use case for Webpack.

In other words, creating a zip bundle manually means you need to follow require() statements to make sure you get all the modules you need and none of the modules you don't. devDependencies can help, but then you need to remember to npm install -production if you're building the bundle locally. Once your project grows beyond the proof-of-concept phase and you want to add a testing framework like Mocha or a linter like eslint, your node_modules will be filled with modules that your Lambda function doesn't need in production. In other words, you need to manually figure out the entire tree of require()-ed files and make sure they're all in your zip file, otherwise your Lambda function will crash.įurthermore, zipping up all of node_modules is a bad idea. Using npm you can easily install Webpack: npm install webpack -save-dev. The first step to using Webpack is installing the necessary dependencies. In this example, we will be using Babel to convert ES6 to ES5 using Webpack. First, we will need to install or otherwise provide a browser-compatible Buffer implementation. Below are 4 easy steps to using Webpack with an existing Node.js web app. With v5, Webpack will no longer polyfill Node.js APIs automatically. But presumably you also want to create some extra Mongoose models, which involves adding another file to your zip command. Before Webpack v5, the polyfilling of many Node.js APIs would be performed automatically. Now, to create a Lambda bundle lambda.zip with a function that uses db.js, you need to zip -r. : Modern Full-Stack Development: Using TypeScript, React, Node.js, Webpack, and Docker : Frank Zammetti : Apress: 2020: true pdfepub: 395: 10 Mb. Module.exports = async function connect( ) )) To start using webpack Node.js API, first install webpack if you haven’t yet: npm install-save-dev webpack Then require the webpack module in your Node. You have a common file that handles connecting to the database called db.js: const config = require( './.config') Motivationįor example, say you're building a couple simple API endpoints in Lambda using Mongoose.

In this article, I'll demonstrate the problem with zipping up Lambda functions yourself and show you how to use Webpack to bundle a Lambda function that connects to MongoDB. node_modules, but that doesn't scale well if you're looking to built a suite of Lambda functions as opposed to a single 'Hello, World' example.

Most simple examples rely on zipping up the entirety of. Resolve.One of the major challenges when working with AWS Lambda is bundling all your node_modules into one zip file. If you don't want to include a polyfill, you can use an empty module like this:
