Summary

This pull request includes several changes to improve the handling of user data and optimize the use of the useEffect hook across the codebase. The most important changes are the addition of user data fetching, updates to the useEffect hook to include dependency arrays, and modifications to the resume service to accept optional user data.

Details

Data Fetching Enhancements:

src/lib/utils/firebase/database/users.ts: Added a new function getUserData to fetch user data from the database.
src/app/(enter-data)/enter-data/page.tsx: Integrated getUserData to fetch user data before calling getResumeFormData. [1] [2]
src/app/(generate-resume)/generate-resume/[slug]/page.tsx: Updated to fetch user data and pass it to getResumeFormData for both base and variant resumes. (src/app/(generate-resume)/generate-resume/[slug]/page.tsxL85-R93, src/app/(generate-resume)/generate-resume/[slug]/page.tsxL98-R117)

State Management Improvements:

src/app/(generate-resume)/generate-resume/[slug]/page.tsx: Added state management for userData and included a check for user credits before proceeding with resume generation. (src/app/(generate-resume)/generate-resume/[slug]/page.tsxR49, src/app/(generate-resume)/generate-resume/[slug]/page.tsxR143-R150)

Code Simplification:

src/lib/services/resume-service.ts: Modified getResumeFormData to accept an optional userData parameter, reducing the need for additional API calls if user data is already available.
Removed unnecessary useEffect dependencies across multiple components to ensure proper effect execution. [1] [2] [3] [4]
