fastify-vite server is not esbuild friendly

[IlyaSemenov]

aws-lambda-fastify is a wrapper that exposes a fastify app as a lambda entrypoint. I'm currently using serverless-http which does the same for Express and Koa. But these libraries are about runtime, not about building. They compile fine with esbuild, there is no problem with that.

The problem with fastify-vite is that the way it is designed, it needs vite builder in production runtime. That is what I'm trying to avoid. By using tree shaking, we can keep that dependency in dev mode but avoid in production, so that the server can be compiled with esbuild.

@IlyaSemenov JSYK at least part of these issues have been resolved in v3 — I'll look closely later. Keeping open.

Interesting, will see what can be done about this.

This is a rather specific use case, I'd personally never use esbuild to bundle Fastify server code, that is, I'd use esbuild only where it's needed (typically for the client). But I'll study this carefully and see what can be done.

BTW New release is almost coming out from dev branch — stay tuned!

Thank you 🙏. The justification for esbuilding is deploying to serverless platforms such as AWS Lambda. It's simpler and faster to distribute a single executable *.js file rather than maintain separate package.json and/or somehow publish parts of node_modules.

Ah, gotcha — maybe we should also look into https://github.com/fastify/aws-lambda-fastify
