How to use an .env variable in Vite with Typescript?

I've an .env file with the following variable:

VITE_GIPHY_KEY=abcdfg

And I'm trying to use that .env variable in src/main.ts like this:

console.log(import.meta.env.VITE_GIPHY_KEY);

I get undefined in the console. How can I use .env variables in Vite with TS?

Solution

  • First I renamed .env to .env.local

    Second, only variables prefixed with VITE_ are exposed to your Vite-processed code. Example:

    VITE_SOME_KEY=123
DB_PASSWORD=foobar

console.log(import.meta.env.VITE_SOME_KEY) // 123
console.log(import.meta.env.DB_PASSWORD) // undefined
