aws-xray-sdk-node VS esbuild

You see in the node xrays sdk that each AWS service is customized with the captureAWSRequest function, which is responsible for the X-Ray calls.

Generally speaking, it is encouraged on serverless-heavy environments (assuming Lambdas, API Gateways, AppSync, DynamoDB and similar services were configured to use it). However, some crucial pieces are still missing, like a proper SQS integration. Bear that in mind.

So what do we get for that? The Tracer module wraps the AWS X-Ray SDK (as a transitive dependency). It doesn't really add any net new capabilities, but makes the SDK easier to work with. In my experience, that SDK is a bit of a bear so this may be well worth it. We can decorate class methods to introduce new trace segments in a single line of code. We can also use the imperative form to add new traces where we see fit. We can capture AWS clients, but that simply exposes the X-Ray SDK.

During my search for deploying Lambdas via GitHub actions, I came across a tutorial that utilized ncc for converting TypeScript and bundling. While ncc is effective, I discovered esbuild, which proved to be significantly faster and perfectly suited to my requirements.

The advent of esbuild, the native support for ES Modules in browsers, the widespread adoption of import map, the emergence of tools like Native Federation, and the Nx ecosystem all combine to forge a flexible and well-maintained Micro Frontend Architecture.

EsBuild is a relatively new, blazing-fast JavaScript bundler and minifier. It stands out for its high performance, significantly speeding up the build process in development pipelines.

Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

Use esbuild to build the React code into a form executable on both the server and client sides.

The functions will bundle using esbuild. For that, it is required to install esbuild globally:

TSX is the newest and most improved version of our ts-node, using ESBuild to transpile TS files to JS very quickly. The most interesting part is that TSX was developed to be a complete replacement for Node, so you can actually use TSX as a TypeScript REPL, if you install it globally with npm i -g tsx, just run tsx in your terminal and you can write TSX natively. But what's even cooler is that you can load TSX for all TypeScript files using --loader tsx when you run your file. For example, let's say we have this file called index.ts:

esbuild plus Vite is out of developer preview and enabled by default, yielding 67%, 87%, 80% speed improvements for build time, hybrid build time and hybrid serve time respectively.

Bundling with esbuild

Besides Webpack, there are many other popular web bundlers available, such as Parcel, Esbuild, Rollup, and more. They all have their own unique features and strengths, and you should make your decision based on the needs and requirements of your specific project. Please refer to their official websites for details.
