serverless-microservices-graphql-template VS serverless-analyze-bundle-plugin

For those that know me, they know I love talking about two things more than anything: Serverless Framework and GraphQL. Today, I'm excited to announce a project starter template that I've been developing that allows developers to build serverless microservices with GraphQL. It is built using Nx monorepos and provides a lot of quality of life developer tooling out-of-the-box. I'll discuss what's in the repo and how you can leverage it today for your own projects. If you want to jump into the code, you can find it on GitHub.

Note that there is one minor drawback, though: Kysely will add 120KB in your Lambdas bundles (props to for serverless-analyze-bundle-plugin for helping me out with this 🙌). It is not a lot, but not negligible either as NodeJS Lambdas bundles above 5MB negatively impacts their cold starts. So you might want to re-evaluate adding Kysely to your bundles if your query is not changing often.

There are plenty of tools out there to optimize the size of your bundles. For instance the Serverless Analyze Bundle Plugin integrates with the Serverless Framework and helps you diagnose which of your NodeJS dependency is not properly tree-shaked.

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:
