From 10cac45daa9dc86a2427adaafc5548d9d4846bb2 Mon Sep 17 00:00:00 2001 From: "g. nicholas d'andrea" Date: Tue, 13 Jan 2026 02:14:35 -0500 Subject: [PATCH] Enable incremental TypeScript compilation with project references - Enable incremental and composite options in tsconfig.base.json - Add project references from pointers to format package - Fix watch mode race condition in format package (run prepare before watch, and have nodemon trigger full prepare on YAML changes) - Add root build script using tsc --build - Update pointers to use tsc --build for prepare/watch - Include test files in format tsconfig (required for composite) - Fix readonly array type in test/guards.ts - Add *.tsbuildinfo to .gitignore Incremental rebuilds are now ~6x faster (0.22s vs 1.37s). --- .gitignore | 1 + package.json | 1 + packages/format/bin/generate-schema-yamls.js | 11 +++++++++-- packages/format/package.json | 4 ++-- packages/format/test/guards.ts | 2 +- packages/format/tsconfig.json | 2 +- packages/pointers/package.json | 4 ++-- packages/pointers/tsconfig.json | 3 ++- tsconfig.base.json | 4 ++-- 9 files changed, 21 insertions(+), 11 deletions(-) diff --git a/.gitignore b/.gitignore index c2658d7d1..ff2c58566 100644 --- a/.gitignore +++ b/.gitignore @@ -1 +1,2 @@ node_modules/ +*.tsbuildinfo diff --git a/package.json b/package.json index 78d6fb480..1c71ed9ef 100644 --- a/package.json +++ b/package.json @@ -5,6 +5,7 @@ "packages/*" ], "scripts": { + "build": "tsc --build packages/format packages/pointers", "bundle": "tsx ./bin/bundle-schema.ts", "test": "vitest", "start": "./bin/start", diff --git a/packages/format/bin/generate-schema-yamls.js b/packages/format/bin/generate-schema-yamls.js index 5f42c890f..3671935f6 100644 --- a/packages/format/bin/generate-schema-yamls.js +++ b/packages/format/bin/generate-schema-yamls.js @@ -33,7 +33,7 @@ const rawSchemas = Object.entries(schemaYamls) .map(([id, yaml]) => ({ [id]: YAML.parse(yaml) })) .reduce((a, b) => ({ ...a, ...b }), {});
