🔗 Linked issue

resolves #1635

📚 Description

This was an issue in test-utils.
config.environments.ssr.resolve.conditions seems to be applied to config.ssr.resolve.conditions for backward compatibility. If 'import' is included in config.ssr.resolve.conditions, Vitest fails to resolve the pg module in test run.

📝 Walkthrough

Walkthrough

This change updates the nuxt:test-utils:browser-conditions Vite plugin in src/config.ts to add a configResolved hook. When SSR-specific resolve conditions are present, the hook filters config.ssr.resolve.conditions to remove the 'import' condition.

Consider returning a partial config instead of mutating config directly.

Vite's plugin API docs recommend returning a partial config object (deep-merged automatically) and reserve direct mutation for cases where merging can't achieve the desired result: It can return a partial config object that will be deeply merged into existing config, or directly mutate the config (if the default merging cannot achieve the desired result). The official configEnvironment example for this exact use case also returns a partial config: configEnvironment(name: string, options: EnvironmentOptions) { // add "workerd" condition to the rsc environment if (name === 'rsc') { return { resolve: { conditions: ['workerd'], }, } } }

♻️ Align with documented pattern

         {
           // https://github.com/nuxt/test-utils/issues/1635
           name: 'nuxt:test-utils:patch-ssr-conditions',
           enforce: 'post',
           configEnvironment(name, config) {
-            if (name === 'ssr' && config.resolve?.conditions) {
-              config.resolve.conditions = config.resolve.conditions.filter(x => x !== 'import')
-            }
+            if (name === 'ssr' && config.resolve?.conditions) {
+              return {
+                resolve: {
+                  conditions: config.resolve.conditions.filter(x => x !== 'import'),
+                },
+              }
+            }
           },
         },

should this live in the plugin above?

[yamachi4416]

Thank you.
config.ssr.resolve.conditions was causing the issue.
updated it to adjust config.ssr via the configResolved hook and unified it into the plugin above.
