The sveltejs/template starter project doesn’t allow the use of environment variables out-of-the-box.
Env can be used by using this module with svelte.
npm install @goesvt/svelte-use-envJust following below code.
in rollup.config.js file
... import insertEnv from "@goesvt/svelte-use-env"; const production = !process.env.ROLLUP_WATCH; ... export default { ..., plugins : [ ..., insertEnv(), // insert here !! ], ... }then, you can create & use .env file as follows
APP_KEY=vr9e29399g83gnrvesd/* App.js */ console.log(process.env.APP_KEY); // vr9e29399g83gnrvesd
