Multiple issues when running vite-jest: fsevents .node, jest-pnp-resolver defaultResolver, ReferenceError: __DEFINES__

[PeterDeKok]

I ran into multiple issues while trying to add (vite-)jest to a vite: vanilla-ts project.

As far as I can tell, these issues are actually caused upstream and therefore not actually issues with vite or vite-jest, they seem mostly limitations of esbuild and rollup.

Also, I could not find a solution that could be implemented in vite-jest, of course I could be wrong...

However, it did stop me from using vite and vite-jest 'out-of-the-box' and therefore want to throw it out here, so other people running into the issue(s) might not have to spend a few days on finding a solution or workaround.

Reproduction:

TLDR Below.

yarn/1.22.17 npm/8.5.0 node/v16.14.2 darwin x64

A project created with vite vanilla-ts template, with added jest and vite-jest.

Running yarn test:unit, gives the following errors:

[vite] error while updating dependencies:

By excluding fsevents and jest-pnp-resolver, from dependency optimization, these errors are no longer thrown.

However, on top of 2 warnings about unsupported async import syntax, a new error pops up:

ReferenceError: __DEFINES__ is not defined

Possibly related issues:

TLDR;

By exluding (only) jest, from dependency optimization, all errors seem gone.

// vite.config.ts
import { defineConfig } from 'vite';

export default defineConfig({
	optimizeDeps: {
        exclude: [ 'jest' ],
    },
});
