vite-plugin-env-switch

U can switch the server env by click the btns on page, and dont need to restart your server by CMD.

change the server env

• vite.config.ts

// vite config 
export default defineConfig({
  //...
  plugins: [
    envSwitchPlugin({
      wsProtocol: 'vite-hmr', // ws protocol
      envs: ['prepare', 'development', 'production'], // env vars
      wsPath: `${wsprotocol}://${host}/${base}:${port}/`, // link
      root: __dirname, // env config root path
      eventName: 'env-check'
    }),
  ]
  //...
})

• inject code in index.html, depend on envs config, there will be some buttons to trigger ws event.
• these code will be inject by transformIndexHtml.transform

<div class="env-btn-wrapper">
  <button class="env-btn" data-env="development">dev</button>
  <button class="env-btn" data-env="prepare">pre</button>
  <button class="env-btn" data-env="production">pro</button>
</div>

• get a ws socket to send event to vite server

const ws = new WebSocket('wss://xx', 'vite-hmr')
document.querySelectorAll('.env-btn').forEach(dom => {
  const { dataset } = dom
  dom.addEventListener('click', () => handleEnv(dataset.env))
})
function handleEnv(env) {
  ws.send(JSON.stringify({ type: 'custom', event: 'env-check', data: { env } }))
}
