I need to know the context of an ENV value

[timscodebase]

In your benchmark project you reference an ENV value in the vite.config.js file

const svg = !!process.env.USE_SVG;

What is this? And how do I set it?

Thank You for everything!

its just a flag to toggle using the preprocessor.

"dev:svg": "USE_SVG=1 vite",
