From 32075d28803344230e6366e2a683b8d3f39b2433 Mon Sep 17 00:00:00 2001 From: silverwind Date: Sat, 10 Aug 2024 11:46:48 +0200 Subject: [PATCH] Add types to various low-level functions (#31781) Adds types to various low-level modules. All changes are type-only, no runtime changes. `tsc` now reports 38 less errors. One problem was that `@types/sortablejs` does not accept promise return in its functions which triggered the linter, so I disabled the rules on those line. --- package-lock.json | 22 ++++++-- package.json | 1 + types.d.ts | 9 ++++ web_src/js/features/dropzone.ts | 2 +- web_src/js/features/repo-issue-list.ts | 2 +- web_src/js/features/repo-projects.ts | 6 +-- web_src/js/features/stopwatch.ts | 2 +- web_src/js/modules/dirauto.ts | 14 +++-- web_src/js/modules/sortable.ts | 6 ++- web_src/js/modules/stores.ts | 3 +- web_src/js/modules/tippy.ts | 47 ++++++++-------- web_src/js/utils/color.ts | 11 ++-- web_src/js/utils/dom.ts | 75 +++++++++++++++----------- 13 files changed, 123 insertions(+), 77 deletions(-) diff --git a/package-lock.json b/package-lock.json index 846cf6f838b8..5c56531ec058 100644 --- a/package-lock.json +++ b/package-lock.json @@ -108,6 +108,7 @@ "stylelint-declaration-strict-value": "1.10.6", "stylelint-value-no-unknown-custom-properties": "6.0.1", "svgo": "3.3.2", + "type-fest": "4.23.0", "updates": "16.3.7", "vite-string-plugin": "1.3.4", "vitest": "2.0.5" @@ -7439,6 +7440,19 @@ "url": "https://github.com/sponsors/sindresorhus" } }, + "node_modules/globals/node_modules/type-fest": { + "version": "0.20.2", + "resolved": "https://registry.npmjs.org/type-fest/-/type-fest-0.20.2.tgz", + "integrity": "sha512-Ne+eE4r0/iWnpAxD852z3A+N0Bt5RN//NjJwRd2VFHEmrywxf5vsZlh4R6lixl6B+wz/8d+maTSAkN1FIkI3LQ==", + "dev": true, + "license": "(MIT OR CC0-1.0)", + "engines": { + "node": ">=10" + }, + "funding": { + "url": "https://github.com/sponsors/sindresorhus" + } + }, "node_modules/globby": { "version": "11.1.0", "resolved": "https://registry.npmjs.org/globby/-/globby-11.1.0.tgz", @@ -12287,13 +12301,13 @@ } }, "node_modules/type-fest": { - "version": "0.20.2", - "resolved": "https://registry.npmjs.org/type-fest/-/type-fest-0.20.2.tgz", - "integrity": "sha512-Ne+eE4r0/iWnpAxD852z3A+N0Bt5RN//NjJwRd2VFHEmrywxf5vsZlh4R6lixl6B+wz/8d+maTSAkN1FIkI3LQ==", + "version": "4.23.0", + "resolved": "https://registry.npmjs.org/type-fest/-/type-fest-4.23.0.tgz", + "integrity": "sha512-ZiBujro2ohr5+Z/hZWHESLz3g08BBdrdLMieYFULJO+tWc437sn8kQsWLJoZErY8alNhxre9K4p3GURAG11n+w==", "dev": true, "license": "(MIT OR CC0-1.0)", "engines": { - "node": ">=10" + "node": ">=16" }, "funding": { "url": "https://github.com/sponsors/sindresorhus" diff --git a/package.json b/package.json index 730c47f90de2..d1a624f11692 100644 --- a/package.json +++ b/package.json @@ -107,6 +107,7 @@ "stylelint-declaration-strict-value": "1.10.6", "stylelint-value-no-unknown-custom-properties": "6.0.1", "svgo": "3.3.2", + "type-fest": "4.23.0", "updates": "16.3.7", "vite-string-plugin": "1.3.4", "vitest": "2.0.5" diff --git a/types.d.ts b/types.d.ts index 3da7cbe05039..a8dc09e06436 100644 --- a/types.d.ts +++ b/types.d.ts @@ -3,6 +3,11 @@ declare module '*.svg' { export default value;
