serverless-esbuild VS node

Support Yarn PnP with externals bundling #327

We use serverless-esbuild to transpile our TypeScript code to JavaScript.

You should use appropriate tools to bundle your Lambda functions with a minimal size. For example, the Serverless Framework, with the serverless-esbuild plugin, automatically bundles your code and uploads it to AWS.

One of the most important aspects of serverless development is keeping an eye on your bundle sizes and to reduce cold start times on Lambda. Keeping this in mind, the template utilizes serverless-esbuild and serverless-analyze-bundle-plugin to provide function analysis out-of-the-box. I opted for serverless-esbuild over serverless-bundle for a few reasons:

Its faster and easier to setup that webpack and drastically reduces the size of the archive. For Serverless framework users there is https://github.com/floydspace/serverless-esbuild and if you use SAM CLI, you already get this for free since they now use esbuild in the build process

if you can, try using https://github.com/floydspace/serverless-esbuild - esbuild is stupid fast and it produces tiny artifacts. Its dead simple too compared to the webpacks/rollups/etc.

Let’s see how we could set up a shiny new JavaScript project using the Yarn package manager. We are going to set up nodenv, install Node.js and Yarn, and then initialize a new project that we will then be able to use as a foundation for our further ideas.

Node.js ( https://nodejs.org/ )

Visit the Node.js website and download the latest version of Node.js for your operating system.

Basic knowledge of Node.js and its environment setup. If you don't have Node.js installed on your system, make sure you download and install it from the official Node.js website.

Node.js can be easily installed from its official website. Depending on your operating system, you can choose the Windows, macOS, or Linux version. Node.js packages come with npm (Node Package Manager), which is essential for managing dependencies in your projects.

To get started with Node.js 22.0.0, you can download the latest version from the official Node.js website. For those upgrading from an older version, it is recommended to test your existing applications for compatibility with the new release, particularly if you are using native modules or rely heavily on third-party npm packages.

Node.js (version 10 or higher)

Before we start, ensure that you have Node.js installed on your computer. This is necessary because we will use Node's package manager (npm) to create our Next.js project. If you need to install Node.js, you can download it from the official Node.js website.

Before starting a new project in react, you need to make sure that you have NodeJS install on your system. You can download the latest version of node at https://nodejs.org. Follow the instructions on the node website to do the installation.
