Fastify SWC TypeScript Server

Overview

This project utilizes Fastify, TypeScript, and SWC to create a robust and efficient server. Fastify's scalability, TypeScript's strong typing and advanced features, and SWC's transpilation contribute to the server's performance. Notably, the typescript package is not a dependency, as SWC handles the transpilation independently. In development mode, the server updates quickly to reflect changes in source files or tests. In production, it operates on optimized JavaScript.

This server template offers a highly advantageous platform for the swift development of serverless functions, which are integral to modern cloud-based applications. These functions, executed in cloud environments, absolve developers from the complexities of managing server infrastructure, concentrating instead on coding. They react to events, such as HTTP requests or database changes, and automatically scale with the demand, making them ideal for fluctuating workloads.

Scripts

Install

Installs the project dependencies.

pnpm i

Dev

Runs the server in development mode. The server immediately updates to reflect changes made to the source files and tests.

pnpm run dev

Test

Runs the Jest test suite.

pnpm run test

Build

Transpiles the TypeScript source files to JavaScript using SWC. The output is saved in the dist directory.

pnpm run build

Start

Runs the transpiled JavaScript code in the dist directory.

pnpm run start
