From f94ff8332aaa2b5f0e2cd8c043d9b5ce29cd3aec Mon Sep 17 00:00:00 2001 From: Matt Godbolt Date: Tue, 20 May 2025 17:53:24 -0500 Subject: [PATCH] Refactor: Split app.ts into smaller modules (#7681) ## Summary This PR significantly improves maintainability by breaking up the 880+ line monolithic app.ts file into smaller, focused modules with proper testing. The code is now organized into dedicated modules under the lib/app/ directory, making the codebase more maintainable and testable. ## Key changes - Extract functionality into modules under lib/app/ directory: - Command-line handling (cli.ts) - Configuration loading (config.ts) - Web server setup and middleware (server.ts) - Core application initialization (main.ts) - URL handlers, routing, rendering, and controllers - Add comprehensive unit tests for all new modules - Make compilationQueue non-optional in the compilation environment - Improve separation of concerns with dedicated interfaces - Ensure backward compatibility with existing functionality - Maintain cross-platform compatibility (Windows/Linux) ## Benefits - Improved code organization and modularity - Enhanced testability with proper unit tests - Better separation of concerns - Reduced complexity in individual files - Easier maintenance and future development This refactoring is a significant step toward a more maintainable codebase while preserving all existing functionality. --- app.ts | 860 +----------------- lib/app.interfaces.ts | 13 +- lib/app/cli.ts | 238 +++++ lib/app/compilation-env.ts | 66 ++ lib/app/compiler-changes.ts | 87 ++ lib/app/compiler-discovery.ts | 134 +++ lib/app/config.interfaces.ts | 43 + lib/app/config.ts | 186 ++++ lib/app/controllers.ts | 80 ++ lib/app/main.interfaces.ts | 45 + lib/app/main.ts | 176 ++++ lib/app/rendering.ts | 142 +++ lib/app/routes-setup.ts | 102 +++ lib/app/server-config.ts | 245 +++++ lib/app/server-listening.ts | 115 +++ lib/app/server.interfaces.ts | 89 ++ lib/app/server.ts | 92 ++ lib/app/static-assets.ts | 129 +++ lib/app/temp-dir.ts | 57 ++ lib/app/url-handlers.ts | 91 ++ lib/compilation-env.ts | 4 +- lib/handlers/noscript.ts | 5 +- lib/logger.ts | 35 +- lib/options-handler.interfaces.ts | 43 + lib/options-handler.ts | 3 +- test/app/cli-tests.ts | 331 +++++++ test/app/compiler-discovery-tests.ts | 232 +++++ test/app/config-tests.ts | 416 +++++++++ test/app/main-tests.ts | 357 ++++++++ test/app/rendering-tests.ts | 241 +++++ test/app/routes-setup-tests.ts | 308 +++++++ test/app/server-config-tests.ts | 179 ++++ test/app/server-listening-tests.ts | 153 ++++ test/app/server-tests.ts | 188 ++++ test/app/static-assets-tests.ts | 92 ++ test/app/temp-dir-tests.ts | 75 ++ test/app/url-handlers-tests.ts | 142 +++ ...lation-env.ts => compilation-env-tests.ts} | 40 +- 38 files changed, 4971 insertions(+), 863 deletions(-) create mode 100644 lib/app/cli.ts create mode 100644 lib/app/compilation-env.ts create mode 100644 lib/app/compiler-changes.ts create mode 100644 lib/app/compiler-discovery.ts create mode 100644 lib/app/config.interfaces.ts create mode 100644 lib/app/config.ts create mode 100644 lib/app/controllers.ts create mode 100644 lib/app/main.interfaces.ts create mode 100644 lib/app/main.ts create mode 100644 lib/app/rendering.ts create mode 100644 lib/app/routes-setup.ts create mode 100644 lib/app/server-config.ts create mode 100644 lib/app/server-listening.ts create mode 100644 lib/app/server.interfaces.ts create mode 100644 lib/app/server.ts create mode 100644 lib/app/static-assets.ts create mode 100644 lib/app/temp-dir.ts create mode 100644 lib/app/url-handlers.ts create mode 100644 lib/options-handler.interfaces.ts create mode 100644 test/app/cli-tests.ts create mode 100644 test/app/compiler-discovery-tests.ts create mode 100644 test/app/config-tests.ts create mode 100644 test/app/main-tests.ts create mode 100644 test/app/rendering-tests.ts create mode 100644 test/app/routes-setup-tests.ts create mode 100644 test/app/server-config-tests.ts create mode 100644 test/app/server-listening-tests.ts create mode 100644 test/app/server-tests.ts create mode 100644 test/app/static-assets-tests.ts create mode 100644 test/app/temp-dir-tests.ts create mode 100644 test/app/url-handlers-tests.ts rename test/{compilation-env.ts => compilation-env-tests.ts} (86%) diff --git a/app.ts b/app.ts index 185d83795..2ae3f64d0 100755 --- a/app.ts +++ b/app.ts @@ -1,4 +1,4 @@ -// Copyright (c) 2012, Compiler Explorer Authors +// Copyright (c) 2025, Compiler Explorer Authors // All rights reserved. // // Redistribution and use in source and binary forms, with or without @@ -26,842 +26,20 @@ // see https://docs.sentry.io/platforms/javascript/guides/node/install/late-initialization/ import '@sentry/node/preload';
