What Build Tool Is Used for Securo Frontend Development (And How It Works)

Securo uses Vite as its frontend build tool, with standard npm scripts for development, production builds, and previewing.

Securo's frontend stack relies on Vite — a modern, fast build tool designed for JavaScript and TypeScript applications. According to the securo-finance/securo source code, Vite powers the entire development workflow from local development through production deployment. This article breaks down how Vite is configured and used in the Securo frontend.

How Vite Is Configured in Securo

The Vite setup lives in two primary files. In frontend/package.json, Vite is declared as the build tool through dedicated npm scripts. The frontend/vite.config.ts file contains the full configuration including plugins, environment loading, and Tailwind CSS integration.

Package.json Scripts

The frontend/package.json defines three core Vite commands:

{
  "scripts": {
    "dev": "vite",
    "build": "tsc -b && vite build",
    "preview": "vite preview"
  }
}

These map to standard Vite lifecycle stages:

• npm run dev — Starts the development server with hot-module replacement (HMR)
• npm run build — Compiles TypeScript and produces a production bundle
• npm run preview — Serves the production build locally for verification

Vite Configuration Details

The frontend/vite.config.ts file implements a dynamic configuration that loads environment variables and registers plugins:

import tailwindcss from '@tailwindcss/vite';
import react from '@vitejs/plugin-react';
import { defineConfig, loadEnv } from 'vite';

export default defineConfig(({ mode }) => {
  const env = loadEnv(mode, process.cwd());
  return {
    plugins: [react(), tailwindcss()],
    server: { port: Number(env.VITE_PORT) || 3000 },
  };
});

Key configuration elements:

• @vitejs/plugin-react — Enables React Fast Refresh and JSX transformation
• @tailwindcss/vite — Integrates Tailwind CSS 4.0's native Vite plugin
• loadEnv — Loads environment variables from .env files based on the current mode
• Dynamic port assignment — Uses VITE_PORT from environment variables, defaulting to 3000

Why Vite for Securo Frontend Development

Vite was chosen for several technical advantages evident in the Securo implementation:

Feature	How Securo Uses It
Instant server start	vite dev launches immediately without bundling delay
Native ESM	Leverages browser ES modules in development for faster updates
Optimized builds	vite build produces highly optimized production assets
Plugin ecosystem	React and Tailwind integration via official plugins
TypeScript support	First-class .ts and .tsx handling without extra configuration

The combination of tsc -b with vite build in the production script ensures type safety before the Vite bundling process begins.

Key Files in the Build System

Understanding the full build context requires examining these files:

• frontend/package.json — Declares Vite dependency and npm scripts
• frontend/vite.config.ts — Central Vite configuration with plugins and environment loading
• frontend/tsconfig.json — TypeScript compiler options used alongside Vite's built-in TS support

These files work together to create a cohesive development experience where Vite handles module resolution, bundling, and optimization while TypeScript provides type checking.

Summary

Securo's frontend build system centers on Vite as the core tool. Key takeaways:

• Vite powers development, build, and preview workflows through frontend/package.json scripts
• Configuration in frontend/vite.config.ts integrates React, Tailwind CSS, and environment variables
• TypeScript compilation precedes Vite bundling in production builds
• The setup follows Vite 5.x+ patterns with native ESM development server

Frequently Asked Questions

Is Vite the only build tool used for Securo's frontend?

Yes, according to the repository source code, Vite is the sole build tool. The package.json does not list Webpack, Parcel, or other alternatives — all build-related scripts delegate directly to Vite commands.

What version of Vite does Securo use?

The source analysis does not specify an exact version, but the configuration uses modern Vite 5.x+ patterns including defineConfig with mode-specific environment loading and the @tailwindcss/vite plugin for Tailwind CSS 4.0.

How do environment variables work with Vite in Securo?

Environment variables load dynamically through loadEnv(mode, process.cwd()) in vite.config.ts. The configuration reads VITE_PORT to set the development server port, falling back to 3000 if undefined. Variables prefixed with VITE_ are exposed to the client code.

Can I customize the Vite configuration for my own Securo deployment?

Yes, modify frontend/vite.config.ts to adjust plugins, build options, or server settings. The defineConfig helper provides full TypeScript intellisense for all Vite configuration options.
