This PR will ensure that the oxide engine doesn't leak in the current stable version.
The oxide engine is currently behind a runtime feature flag:
But some build tools that use the commonjs plugin (often used in Vite / Rollup) will hoist that
require
part out of the guard... this typically results in a static import instead. But since the stable engine doesn't have any idea what@tailwindcss/oxide
even is, it crashes.If you would inspect the generated code, then it will look something like this:
... which kind of defeats the whole purpose of the feature flag in the first place. In a project where
OXIDE
is defined this all works fine, but in other places it won't.This PR will switch the runtime feature flag, to a build time feature flag. This will ensure that the code is not even there in the final built code but that should be fine since you can switch between the engines if you install a different version (
insiders
vsoxide-insiders
).We will replace
__OXIDE__
at build time. This also means that some parts of the code will now look something likeif (false) { require('@tailwindcss/oxide') }
. This means that the block will never be reachable, but luckily SWCs optimizer will get rid of the dead code entirely.
