refactor: move fs based inc cache to next-server #36246

huozhi · 2022-04-18T16:30:21Z

In edge runtime, node.js polyfills should not be applied, move more nodejs specific code (fs related) to next server before removing them

@@ -67,11 +68,13 @@ function runTestsAgainstRuntime(runtime) {
          invalidPage.write(`export const value = 1`)
        }
        nextConfig.replace("// runtime: 'edge'", `runtime: '${runtime}'`)
+        indexPage.replace("// runtime: 'edge'", `runtime: '${runtime}'`)


Setting page runtime to edge, this wasn't coverred before cause it will be statically optimized.
Adding this to avoid the basic build failed when removing the nodejs polyfills
