Warning: "deps.registerNodeLoader" is deprecated

[jtmueller]

When running vitest 0.34.2, if I have vite-plugin-solid registered as a plugin, the following warning is logged:

Vitest "deps.registerNodeLoader" is deprecated. If you rely on aliases inside external packages, use "deps.optimizer.web.include" instead.

If I remove vite-plugin-solid from the vitest config, no warnings are logged.

Same with me. Another weird thing that I cannot figure out for the life of me @jtmueller is that when I have the vite-plugin-solid plugin enabled in my vite config, my tests all are duplicated (they each run twice)!! Have you noticed this at all? It is driving me insane, haha. See here: https://github.com/solidjs/vite-plugin-solid/issues/112#issuecomment-1698476208

You can remove the warning by using optimizer and server config:

  test: {
    server: {
      deps: {
        // fixes: You appear to have multiple instances of Solid. This can lead to unexpected behavior.
        inline: [/solid-js/],
      },
    },
    deps: {
      // fixes: Vitest "deps.registerNodeLoader" is deprecated. If you rely on aliases inside external packages, use "deps.optimizer.web.include" instead.
      optimizer: {
        web: {
          enabled: true,
        },
      },
    },
  }

https://github.com/vitest-dev/vitest/releases/tag/v0.34.0 From release notes:

Deprecate deps.registerNodeLoader - by @sheremet-va (7f45b) This option was introduced to support aliasing inside external packages. Please, use deps.optimizer.web instead. If you test Node.js applications, consider adding external packages to server.deps.inline.

@alarivan Thanks, that gets rid of the warning for me - I was logging the issue mostly so that the next version of vite-plugin-solid wouldn't trigger the deprecation warning by default, but I appreciate the workaround.

@GitMurf I was seeing the deprecation warning twice, but at least after applying the above workaround, the actual tests don't seem to run more than once.

@GitMurf I was seeing the deprecation warning twice, but at least after applying the above workaround, the actual tests don't seem to run more than once.

When I am running my unit tests with vitest, whenever I use my main vite config that has the vite-plugin-solid included, it runs my tests twice!

FYI see this thread for the solution to my additi issue mentioned above: https://github.com/solidjs/vite-plugin-solid/pull/101#issuecomment-1698495511

Why is that not working for me?

• vitest 0.34.6
• vite 4.5.0
• vite-plugin-solid 2.7.2 My vitest.config.ts

And I get this

@Tur8008 I was also unable to suppress the deprecation message using the above recommendations.

This message seems to be caused by the SolidPlugin()'s returned config-patch object that contains the deprecated property:

https://github.com/solidjs/vite-plugin-solid/blob/7e667ad0bb05ba55e0a4a3e185ecc7e3e3535e4f/src/index.ts#L338

I was able to develop a workaround that patches-out the deprecated property (setting it to undefined) which effectively suppresses the deprecation message when running vitest:

vite@4.5.0 vitest@0.34.6 vite-plugin-solid@2.7.2.

- import { defineConfig } from "vitest/config";
+ import { type UserConfig, defineConfig } from "vitest/config";
import SolidPlugin from "vite-plugin-solid";

export default defineConfig({
  // ...
  plugins: [
-    SolidPlugin(),
+    // @workaround
+    // `"deps.registerNodeLoader" is deprecated.`
+    (() => {
+      const plugin = SolidPlugin();
+      const { config } = plugin;
+      return Object.assign(plugin, {
+        config: async (...args: any[]) => {
+          const result: UserConfig = await (config as any)(...args);
+          if (result.test?.deps?.registerNodeLoader) {
+            result.test.deps.registerNodeLoader = undefined;
+          }
+          return result;
+        },
+      });
+    })(),
  ],
  // ...
});

I'm not sure whether or not this patched-out property will cause any other problems -- but for now it seems okay!

[edit 1] ~Sorry, it seems to completely crash vite dev with TypeError: Cannot read properties of undefined (reading 'deps') -- I'll have to look into it further.~

[edit 2] Turns out I made a mistake in the original version of my workaround diff causing a config error if not running in the "test" mode. I've fixed my code snippet to first check for the property before attempting to clear it.

Works also with vitest@1.2.1, vite@5.0.11 and vite-plugin-solid@2.8.2

Works also with vitest@1.2.1, vite@5.0.11 and vite-plugin-solid@2.8.2 Yepp! Just have updated site-plugin-solid up to 2.9.1 and problem has gone. Thank you! They fixed that, at last.
