The JavaScript toolkit to build full stack apps and frameworks with your own opinions.
powered by vite and nitro

vinxi

Compose full stack applications (and frameworks) using Vite, the versatile bundler and dev server, and Nitro, the universal production server.

Inspired by the Bun.App API, the core primitive in Vinxi is the router, which is simply a brief specification defining how a group of URLs should be handled.

Vinxi supports many common router types:

• 'static' - for serving uncompiled, static assets
• 'http' - for creating traditional web servers
• 'spa' - for building and serving single page application assets
• 'client' - for building and serving of SSR application assets
• custom - for adapting Vinxi to your use case

Creating a new router is as simple as adding a specification object to the routers array in the createApp call:

import { createApp } from "vinxi";

export default createApp({
  routers: [
    // A static router serving files from the `public` directory
    {
      name: "public",
      type: "static",
      dir: "./public",
      base: "/",
    },
    // A http router for an api
    {
      name: "api",
      type: "http",
      handler: "./app/api.ts",
      base: "/api",
      plugins: () => [
        // Vite plugins applying exclusively to `http` router
      ],
    },
  ],
});

Frameworks actively being developed on vinxi:

• SolidStart

There are also a few other frameworks experimenting with vinxi:

• AngularStart

Examples

Framework	Category	Example	StackBlitz Link
React	RSC	SPA
	SPA	Basic
		MDX
		TanStack Router (Pages)
		TanStack Router (App)
		Wouter
	SSR	Basic
		Basic w/Cloudflare
		TanStack Router (App)
		Wouter
Solid	SPA	Basic
	SSR	Basic
		Solid Router
Vanilla		SPA
		TRPC

Goals

Primary goal is to build the tools needed to build a NextJS or SolidStart style metaframework on top of vite without worrying about a lot of the wiring required to keep dev and prod working along with SSR, SPA, RSC, and all the other acronyms. etc. On top of that, we should be able to deploy anywhere easily.

Mostly trying to disappear for the user outside the app.js file

The surface layer we are intending to tackle:

1. Full stack builds (handle manifest stuff to figure out what assets to load at prod runtime)
2. Dev time asset handling (avoiding FOUC in SSR frameworks) and smoothing over some of vite's dev/prod mismatching behaviours by providing common manifest APIs that work in dev and prod the same way
3. File system router (not any specific file system conventions, just an API for interfacing with FileSystemRouters and utils to implement your conventions in them)
4. Building the server, and providing a simple opaque handler API to control the server
5. Adapter stuff to deploy to various platforms with support for all the features they provide
6. Not to abstract away the platforms. Let people use what they want to the fullest
7. Have little opinion about how the app should be authored or structured

Roadmap

• vinxi deploy
• hooks throughout the app licycle:
  • dev: app:created, app:started, router:created

Try it out

npm install vinxi

React SSR

import reactRefresh from "@vitejs/plugin-react";
import { createApp } from "vinxi";

export default createApp({
  routers: [
    {
      name: "public",
      type: "static",
      dir: "./public",
    },
    {
      name: "client",
      type: "client",
      handler: "./app/client.tsx",
      target: "browser",
      plugins: () => [reactRefresh()],
      base: "/_build",
    },
    {
      name: "ssr",
      type: "http",
      handler: "./app/server.tsx",
      target: "server",
    },
  ],
});

Solid SSR

import { createApp } from "vinxi";
import solid from "vite-plugin-solid";

export default createApp({
  routers: [
    {
      name: "public",
      type: "static",
      dir: "./public",
    },
    {
      name: "client",
      type: "client",
      handler: "./app/client.tsx",
      target: "browser",
      plugins: () => [solid({ ssr: true })],
      base: "/_build",
    },
    {
      name: "ssr",
      type: "http",
      handler: "./app/server.tsx",
      target: "server",
      plugins: () => [solid({ ssr: true })],
    },
  ],
});
