Describe the bug

If a wasm contains imports from relative path, the module name will have foreign unintended characters.

For context, photon-rs has some imports from relative path, and using it causes the following error:

(inject plugin) rollup-plugin-inject: failed to parse ~/Developer/play/nitro-wasm/routes/wasm/photon_rs_bg.wasm. Consider restricting the plugin to particular files via options.include
routes/wasm/photon_rs_bg.wasm (6:2) Error when using sourcemap for reporting an error: Can't resolve original location of error.

This issue is resolved when moduleName is json-stringified at L180 in https://github.com/unjs/unwasm/blob/67a94a9d4f203db9a9864fcb0b8c2d0912c575c1/src/plugin/runtime.ts#L180-L186

I patched it temporarily:

I would highly appreciate a runnable reproduction 🙏

There are probably easier ways to include a repro, but I ran in to the same problem with Prismas new database adapters.

Here's a repro-link codesandbox.io.

If you try yourself with prisma, it does require you to have generated the prisma client before building:

node_modules/.bin/prisma generate

I'm not able to reproduce this at the moment; but @Zn4rK 's reproduction aligns with the issue I had

Okay, i will try to assmble a reproduction for photon as well to track both separately 👍🏼 There might be same common issues but we always need reproduction to make sure all root causes are fixed.

I will be able to provide a repro for photon by Sunday, as it happened on my work pc; And i couldn't make it happen again on my personal one.

The issue so far is that key in imports object should have been enclosed by quotes.

Thanks for nice reproduction @mukundshah. Added a fix via https://github.com/unjs/unwasm/pull/24 keeping this issue open until make sure photon is fully compatible.
