Variables

To declare environment variables for Vite, create .env.<mode> files in the root of your project
- Example:
```
DB_PASSWORD=foobar
VITE_SOME_KEY=123
```
- Note the strings assigned to the variables are not quoted. Added quotes results in the quotes being included when replaced
Vite only has access to variables with names prefixed with VITE_
- In the example above, Vite will have access to the VITE_SOME_KEY variable at build time but will not have access to DB_PASSWORD
To use the variable, reference it as a property on the object import.meta.env
- To reference the VITE_SOME_KEY variable declared above, you would reference it like this: import.meta.env.VITE_SOME_KEY
- Unlike other Javascript objects, you can not reference the environment variable as import.meta.env['VITE_SOME_KEY]'. These environment variables are replaced statically at build time, and only the dot syntax is replaced.
- If you want the variable to be a string value in Javascript, you must include your own quotes.
  - Example: const key = 'import.meta.env.VITE_SOME_KEY';
You cannot use these environment variables in vite.config.js since it is a node script and is not built by Vite.

Modes

You can create arbitrary modes by creating .env files for those modes
- Example: .env.staging creates a mode called “staging”
To build in a mode, run vite build --mode <mode>
- Example: vite build --mode staging
Running vite build builds using the .env.production variables
