Sourcemap generated on windows includes \\ for paths. Should be /

[matthiasg]

In order for Chrome to resolve sourcemaps correctly (especially when using workspaces) the sources property in the sourcemap should specify forward slashes not escaped backward slashes.

E.g.

"sources": ["node_modules\\test\\src\\test2.js", "node_modules\\test\\src\\index.js", "src\\test\\index.ts", "src\\index.ts"]

should be

 "sources": ["node_modules/test/src/test2.js", "node_modules/test/src/index.js", "src/test/index.ts", "src/index.ts"]

Thanks for reporting. I'm guessing this is because these are really URLs, not paths, and should be treated as such. It's also not great that esbuild's output is different depending on the platform it's running on even independent of this issue. I'll fix this sometime soon.

Thanks. Great ! we always build on windows, linux, and mac to ensure consistency.
