Subject: [PATCH] chore: refine esbuild & node detection
|
|||
|
|
|
|||
|
|
When using the loader for external builtins, `esbuildDetection` is
|
|||
|
|
undefined. This commit defines `__UNDICI_IS_NODE__` on `globalThis`
|
|||
|
|
in the loader and deletes it after loading Undici. `esbuildDetection`
|
|||
|
|
has also been extracted as a variable at the top level of the module,
|
|||
|
|
to support deleting `__UNDICI_IS_NODE__` on `globalThis` to avoid
|
|||
|
|
polluting the global namespace.
