jsc.paths transform produces absolute paths (Windows only)

[colin969]

Describe the bug

jsc.paths transformation produces absolute paths instead of relative paths. This only occurs on Windows, the paths are relative when run on Linux.

Example project: https://github.com/colin969/swc-issue-01-colin969

"use strict";
const _import = require("./import");
console.log(_import.test);

Actual behavior

"use strict";
const _import = require("C:/Data/Projects/swc-bug/src/import");
console.log(_import.test);

Where C:/Data/Projects/swc-bug is the project path

Facing the same issue. Have you found a solution?

[colin969]

Nope, had to go back to ttypescript and only use SWC for the frontend w/ webpack.

Seems like this is fixed. I bought a Windows device and could reproduce this, but I couldn't reproduce it with a latest @swc/core.
I'll close this issue with a PR adding a test for it
