fix: skip undefined proxy entry

fix(vite/node): Cannot read properties of undefined: configure

When does this happen? IIUC when the config is like below?

export default defineConfig({
  server: {
    proxy: {
      '/api': undefined
    }
  }
}

In that case, I think it's better to skip from here with if (!opt) return.

vite/packages/vite/src/node/server/middlewares/proxy.ts

Lines 40 to 45 in 70b4baa

	Object.keys(options).forEach((context) => {
	let opts = options[context]
	if (typeof opts === 'string') {
	opts = { target: opts, changeOrigin: true } as ProxyOptions
	}
	const proxy = httpProxy.createProxyServer(opts) as HttpProxy.Server

Then, we won't need to check if the value is undefined or not in proxies.

vite/packages/vite/src/node/server/middlewares/proxy.ts

Line 86 in 70b4baa

const [proxy, opts] = proxies[context]

[lbiceman]

import { defineConfig, loadEnv } from 'vite'
export default function ({ command, mode }) {
const root = process.cwd();
const env = loadEnv(mode, root);
return defineConfig({
base: './',
server: {
host: true,
port: 9095,
proxy: {
'/logicFlow': env.VITE_SERVER_ADDR
}
}
})
}

@lbiceman, following up in case you're waiting for us here. I think you should implement @sapphi-red suggestion to move this PR forward. if you are busy, don't worry, we'll modify the PR at one point and merge it. Thanks again!

@sapphi-red function proxyMiddleware。When the options[context] is undefined, the current loop should be skipped。
