Account Merging Example

A simple task management app built with Wasp that demonstrates how to implement account merging functionality in user-land using merge codes.

Account merging allows users to consolidate multiple accounts (created with different authentication methods) into a single account.

Getting Started

Make sure you have Wasp installed. Then, clone this repository and navigate into the project directory:

wasp db migrate-dev
wasp start

For Google OAuth, you'll need to set up your Google OAuth credentials in .env.server:

GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret

How This Implementation Works

This app demonstrates a merge code approach to account merging:

1. Generate Merge Code: User generates a temporary merge code in their target account (the account they want to keep)
2. Use Merge Code: User logs into their source account (the account to be merged) and enters the merge code
3. Account Merge: The system transfers all data from the source account to the target account and deletes the source account

Take a look at the following files for the implementation details:

• ./src/merge/actions.ts: Contains the logic for generating and using merge codes, as well as merging accounts.
  • generateMergeCode: Generates a unique merge code for the target account.
  • validateMergeCode: Validates the provided merge code.
  • mergeAccounts: Merges the source account into the target account using the merge code.
• ./src/merge/AccountMergePage.tsx: The UI for generating and using merge codes.
• ./schema.prisma: Database schema including the MergeCode model.
