# Server

You can configure server behaviors with a simple file server.config.js located in the root folder of your application.

# Plugins

Like UVue plugins, you can install or write your own plugins for server side. These plugins can add middlewares to HTTP server, log things during each HTTP requests, or rewrite HTML output sended to clients.

See more informations: Server plugins

# HTTPS

In server.config.js:

export default {
  https: {
    key: '',
    cert: '',
  },
};

# HTTP/2

You can enable HTTP/2 server with a simple comfiguration:

In server.config.js:

export default {
  http2: true,
};

# Vue renderer / directives

For Vue directives you have to rewrite them make them compatible with SSR. You can define these rewrites in server config file.

In server.config.js:

export default {
  renderer: {
    directives: {
      // Place your directives here
    },
  },
};

You can also customize cache used by renderer (default to lru-cache) or change preload and prefetch behaviors:

export default {
  renderer: {
    cache: null,
    shouldPrefetch: null,
    shouldPreload: null,
  },
};

• API Directives
• Cache
• shouldPreload / shouldPrefetch

# Dev server

In development mode, you can customize HMR behaviors too:

export default {
  devServer: {
    middleware: {
      // ...
    },
    hot: {
      // ...
    },
  },
};

export default {
  watch: ['server.config.js', 'src/server/**/*.js'],
  watchIgnore: ['node_modules'],
};

• Dev middleware options
• Hot middleware options

# Adapters

By default UVue use a connect instance to process HTTP requests and send responses to clients, but you can change this very easly.

# Use Express

First install dependency:

npm install express

Then setup your server configuration to use ExpressAdapter, in server.config.js:

import { ExpressAdapter } from '@uvue/server';

export default {
  adapter: ExpressAdapter,
};

# Use Fastify

First install dependency:

npm install fastify

Then setup your server configuration to use FastifyAdapter, in server.config.js:

import { FastifyAdapter } from '@uvue/server';

export default {
  adapter: FastifyAdapter,
};

# Use Koa

First install dependencies:

npm install koa koa-mount koa-static koa-compress
npm install -D koa-webpack # For ssr:serve command

Then setup your server configuration to use KoaAdapter, in server.config.js:

import { KoaAdapter } from '@uvue/server';

export default {
  adapter: KoaAdapter,
};
