- Add TypeScript type annotations to all migrated files: * Wrap Vue Options API components with defineComponent for proper type inference * Convert directives (Closeable, Float) to ES6 exports with proper types * Add comprehensive type safety to utilities (utils, urls, pubsub, dropdown, submenu) * Fix NodeList.ts with proper type handling and linting compliance * Add 'this: any' parameters to QuizQuestionMixin for dynamic property access - Configure build tools for TypeScript: * Install and configure @babel/preset-typescript * Update babel.config.js with TypeScript preset * Configure Jest with ts-jest for test transformation - Configure ESLint for TypeScript + Vue: * Add packages/vue-components/tsconfig.lint.json for ESLint * Update root .eslintrc.js to include vue-components tsconfig in project array * Configure vue-components/.eslintrc.js with vue-eslint-parser and TypeScript support * Add .eslintignore to exclude coverage and config files from linting * Configure import resolver to handle .ts file resolution * Add overrides for .js files to not require TypeScript project - Fix all linting errors without disabling rules: * Fix 83 linting errors in NodeList.ts (bitwise operators, parameter reassignments, for-in loops) * Fix 32 linting errors in utils.ts (nested ternaries, line length, typeof checks) * Reorder function declarations to fix no-use-before-define errors * Add inline eslint-disable only for unavoidable legacy patterns (lodash checks where lodash isn't available) * Replace ~arr.indexOf(x) with arr.indexOf(x) !== -1 * Replace for-in loops with Object.keys().forEach() * Fix parameter reassignments by using local variables * Break up nested ternaries into if-else statements * Use Number.isNaN instead of isNaN - Configure Vue-specific TypeScript settings: * Set strict: false for incremental migration * Disable noImplicitAny and noImplicitThis for Vue Options API compatibility * Configure jsx: 'preserve' for Vue template compilation
