netlify-frameworks-vite

Setup guidance for running Vite and React web applications on Netlify, a hosting platform. It covers the Netlify Vite plugin and its connection to Netlify features.

In plain words
What is it for?
Use it when adding the Netlify Vite plugin to a React project and preparing Netlify Functions, Blobs, or database features.
Why use it?
It reduces configuration mistakes and warns against choosing unverified package versions when installing the deployment plugin.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

netlify-frameworks-vite scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vite + React on Netlify

Setup

Check current versions before pinning. Knowledge cutoffs lag behind npm, and guessing a version tends to fail (npm install rejects it, or worse, installs something incompatible). Before pinning @netlify/vite-plugin, vite, @vitejs/plugin-react, or any other package in package.json, run npm view <pkg> version to get the current latest. Or omit explicit pins and let npm install pick them up. If that check itself fails (no network, registry unreachable), still don't fall back to a guessed exact pin — install without a version (or with @latest) and tell the user live verification wasn't possible so they should confirm the installed versions. Never present an unverified x.y.z as the current release.

Install the Netlify Vite plugin as a dev dependency (it's a build/dev-time tool, not a runtime dependency):

npm install -D @netlify/vite-plugin
// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import netlify from "@netlify/vite-plugin";

export default defineConfig({
  plugins: [react(), netlify()],
});

What the Plugin Does

  • Enables Netlify Functions, Blobs, DB, and environment variables in local dev
  • Handles build output for Netlify deployment
  • No need for netlify dev — run npm run dev directly

SPA Routing

For client-side routing (React Router, etc.), add the catch-all redirect:

# netlify.toml
[[redirects]]
from = "/*"
to = "/index.html"
status = 200

Netlify Functions

Write functions in netlify/functions/ as usual. The Vite plugin makes them available during local dev at their configured paths.

// netlify/functions/api.ts
import type { Config, Context } from "@netlify/functions";

export default async (req: Request, context: Context) => {
  return Response.json({ message: "Hello from API" });
};

export const config: Config = { path: "/api/hello" };

Forms (AJAX Pattern)

Since Vite + React renders forms client-side, include a hidden HTML form for Netlify to detect, and submit via AJAX:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

netlify-frameworks-vite is a cursor rule published in the GitHub repository netlify/context-and-tools (36 stars, last pushed 6d ago), licensed MIT. It adds 17 tokens to every session and 820 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
