Console.log is not removing while building the app with react router v7

[saugatclinch-netizen]

import tailwindcss from "@tailwindcss/vite";
import { defineConfig } from "vite";
import tsconfigPaths from "vite-tsconfig-paths";

export default defineConfig({
	plugins: [tailwindcss(), reactRouter(), tsconfigPaths()],
	server: {
		port: 5173,
	},
	esbuild: {
		drop: ["console"],
	},
});

First distinguish logs in generated client JS, generated server JS and build-tool output. A build minifier does not silence Vite or framework tooling itself.

A documented alternative is explicit Terser minification (npm install -D terser):

build: {
  minify: 'terser',
  terserOptions: {
    compress: { drop_console: true },
  },
}

Merge this into your existing configuration. For a framework with multiple build environments, confirm the effective client/server configs both receive it; SSR minification is disabled by default in Vite. Then inspect the generated JS rather than source-map originals. Dropping all console calls also drops errors/warnings and can remove evaluation of arguments, so logging calls must not contain essential side effects. Without your dependency versions and a small reproduction, I cannot confirm why the existing esbuild.drop setting is ineffective.

Prepared with AI assistance and checked against the linked documentation. I have not reproduced your original project locally.

If this is Vite 8, esbuild.drop is not wired to the Rolldown/Oxc minifier anymore, so the option is silently ignored. React Router is not doing anything special here. Move it to the minifier config:

build: {
 rolldownOptions: {
 output: {
 minify: {
 compress: { dropConsole: true, dropDebugger: true }
 }
 }
 }
}

On Vite 7 or older, your existing esbuild.drop should work for direct console.* calls. Then I would check vite --version, make sure you are inspecting the client bundle, and look for window.console.* or dependency aliases like l.warn, which drop will not catch.
