icefog

a utility for passing environment/config info from server to client

install

pnpm -D add icefog

use

On the server, create a config string:

import { createConfig } from 'icefog/server'

const configString = createConfig({ isDev: true, token: 'abc' })
// then add this string to your rendered markup
// e.g. - `<div id="app" ${configString}></div>`

Then on the client, read the config string:

import 'icefog/init' // for the default element of '#app'

or

import { initConfig } from 'icefog'
initConfig('my-dom-element')

the config export is then available for use anywhere in your app:

import { config } from 'icefog'

if (config.isDev) // do development-specific things
